     2. Description of the Related Art 
     With the progress of miniaturization of semiconductor devices, the treatment, such as etching or washing, with a treatment liquid used in the semiconductor device manufacturing process is increasingly required to be more accurately performed with high efficiency. 
     For example, JP2004-101849A discloses a washing agent composition containing N-hydroxyformamide, and the like. 
     SUMMARY OF THE INVENTION

Furthermore, the treatment liquid is also required, for example, to be able to demonstrate constant performance even after a lapse of time and to have excellent stability.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Hereinafter, the present invention will be specifically described. 
     The following constituents will be described based on typical embodiments of the present invention in some cases, but the present invention is not limited to the embodiments. 
     In the present specification, the range of numerical values described using “to” means a range including the numerical values listed before and after “to” as the lower limit and the upper limit. 
     Furthermore, in the present invention, “ppm” means “parts-per-million (10 −6 )”, “ppb” means “parts-per-billion (10 −9 )”, and “ppt” means “parts-per-trillion (10 −12 )”. 
     In the present specification, “room temperature” is “25° C.”. 
     [Treatment Liquid] 
     The treatment liquid according to an aspect of the present invention contains water, hydroxylamine, and one or more kinds of hydrazines selected from the group consisting of hydrazine, a hydrazine salt, and a hydrazine derivative, in which a content of the hydrazines is 1 part by mass or less with respect to 100 parts by mass of the hydroxylamine. 
     It is unclear what mechanism works for the treatment liquid constituted as above to achieve the above objects. According to the inventors of the present invention, the mechanism is considered to be as below. 
     That is, in the treatment liquid according to the aspect of the present invention, water contains both the hydroxylamine and hydrazines. Hydrazines have more nitrogen atoms than hydroxylamine, and nitrogen atoms have more unshared electron pairs than hydroxylamine. 
     Presumably, because hydrazines are adequately rich in unshared electron pairs on nitrogen, the coexistence of the hydrazines and the hydroxylamine may enable the hydrazines and/or hydroxylamine to suitably interact with an organic substance, which may enable the treatment liquid to exhibit excellent organic residue removability. In addition, presumably, because the content of the hydrazines is equal to or less than a predetermined amount, hydroxylamine decomposition that may occur during storage of the treatment liquid may be suppressed, which may contribute to the excellent stability of the treatment liquid. 
     Furthermore, in a case where the treatment liquid according to the aspect of the present invention contains a predetermined type and amount of anions, either or both of the removability for residues that the object to be treated can further contain and contain a metal as a main component (hereinafter, the removability will be also simply called “metal residue removability of the treatment liquid”) and surface smoothness of a metal-containing substance (such as a cobalt-containing substance) that the object to be treated having been treated can contain (hereinafter, the surface smoothness will be also simply called “smoothness of the object to be treated”) are also excellent. 
     Hereinafter, regarding the treatment liquid according to the aspect of the present invention, further improving organic residue removability, stability, metal residue removability, and/or smoothness of the object to be treated will be also simply described as “further improving the effects of the treatment liquid”. 
     Hereinafter, the components contained in the treatment liquid according to the embodiment of the present invention will be specifically described. 
     &lt;Water&gt; 
     The treatment liquid contains water. 
     The water is not particularly limited, and examples thereof include distilled water, deionized water, and pure water. 
     The content of water in the treatment liquid is not particularly limited. The content of water with respect to the total mass of the treatment liquid is preferably 50% by mass or more, more preferably 70% by mass or more, and even more preferably 80% by mass or more. The upper limit of the content of water is less than 100% by mass. 
     &lt;Hydroxylamine&gt; 
     The treatment liquid contains hydroxylamine (NH 2 OH). 
     The hydroxylamine may be ionized in the treatment liquid. 
     The content of hydroxylamine is not particularly limited. In view of further improving the effects of the treatment liquid, the content of the hydroxylamine compound with respect to the total mass of the treatment liquid is preferably 0.001% to 25% by mass. 
     In a case where the content of hydroxylamine is 0.001% by mass or more with respect to the total mass of the treatment liquid, the washing properties of the treatment liquid are further improved. In a case where the content of hydroxylamine is 25% by mass or less with respect to the total mass of the treatment liquid, the smoothness of the object to be treated is further improved. 
     In order that the performances of the treatment liquid are well balanced, the content of hydroxylamine with respect to the total mass of the treatment liquid is, for example, preferably 0.05% to 15% by mass, more preferably 0.1% to 10% by mass, and even more preferably 0.5% to 8% by mass. 
     The content of hydroxylamine in the treatment liquid can be measured by ion chromatography (Dionex ICS-2100 from Thermo Fisher Scientific Inc., or the like). 
     Furthermore, in a case where the components and formulation of the raw materials used for preparing the treatment liquid are known, the content of hydroxylamine may be calculated from the amount of the compound formulated. 
     &lt;Hydrazines&gt; 
     The treatment liquid contains one or more kinds of hydrazines selected from the group consisting of hydrazine, a hydrazine salt (a salt of hydrazine), and a hydrazine derivative (a derivative of hydrazine). 
     The hydrazine derivative may be a salt or a derivative other than a salt. 
     Examples of the hydrazine salt include hydrazine sulfate, hydrazine hydrochloride, and hydrazine acetate. 
     Examples of the hydrazine derivative include a compound represented by General Formula (A) (a compound represented by H 2 N—N—R N   2 ), a compound represented by General Formula (B) (a compound represented by H 2 N—N═X), a compound having a pyrazole ring (pyrazols), a salt of these (such as sulfate, hydrochloride, or acetate). 
       H 2 N—N—R N   2   (A)
 
       H 2 N—N═X  (B)
 
     It is also preferable that the hydrazine derivative be not azoles (such as benzotriazoles) other than pyrazoles. 
     In General Formula (A) (H 2 N—N—R N   2 ), two R N &#39;s each independently represent a hydrogen atom or a substituent. Two R N &#39;s may be bonded to each other to form a ring. Here, at least one of two R N &#39;s is not a hydrogen atom (in other words, at least one of two R N &#39;s is a substituent, or two R N &#39;s are bonded to each other to form a ring). 
     As the substituent represented by R N , an alkyl group which may have a substituent (the alkyl group may be linear or branched, and preferably has 1 to 5 carbon atoms) or -L N -NH 2  (L N  represents a single bond or a divalent linking group, and the divalent linking group is preferably —CO—, —CS—, —NH—, —C(═NH)—, or a group consisting of a combination of two or more of these groups) is preferable. 
     In General Formula (B) (H 2 N—N═X), X represents a divalent group. Especially, X is preferably ═CR C   2 . Two R C &#39;s each independently represent a hydrogen atom or a substituent. 
     In the hydrazine derivative, the total number of atoms other than hydrogen atoms is preferably 3 to 30, more preferably 3 to 15, and even more preferably 3 to 8. 
     Specific examples of the hydrazine derivative include pyrazole, carbohydrazide, semicarbazide, thiosemicarbazide, monomethylhydrazide, t-butylhydrazine, dimethylhydrazine (1,1-dimethylhydrazine), and aminoguanidine. 
     It is preferable that the hydrazines contain at least hydrazine among the above. 
     The content of hydrazine with respect to the total mass of the hydrazines is preferably 20% to 100% by mass, and more preferably 50% to 100% by mass. 
     In the treatment liquid, the total content of the hydrazines (preferably hydrazine) with respect to 100 parts by mass of the hydroxylamine is 1 part by mass or less. In view of further improving the stability of the treatment liquid, the total content of the hydrazines is preferably 0.5 parts by mass or less. In view of further improving the organic residue removability of the treatment liquid, the total content of the hydrazines is preferably 0.00001 parts by mass or more, more preferably 0.0001 parts by mass or more, even more preferably 0.0005 parts by mass or more, and particularly preferably 0.005 parts by mass or more. 
     In the treatment liquid, the total content of the hydrazines (preferably hydrazine) is preferably 0.0001 to 3,000 ppm by mass with respect to the total mass of the treatment liquid. In a case where the total content of the hydrazines is 0.0001 ppm by mass or more (preferably 0.0005 ppm by mass or more, more preferably 0.005 ppm by mass or more, and even more preferably 0.05 ppm by mass or more), the organic residue removability of the treatment liquid is further improved. In a case where the total content of the hydrazines is 3,000 ppm by mass or less (preferably 300 ppm by mass or less), the stability of the treatment liquid is further improved. 
     The type and content of the hydrazines in the treatment liquid can be measured by ion chromatography (Dionex ICS-2100 from Thermo Fisher Scientific Inc., or the like). Furthermore, in a case where the components and formulation of the raw materials used for preparing the treatment liquid are known, the content of hydroxylamine may be calculated from the amount of the compound formulated. 
     The method for introducing hydrazines into the treatment liquid is not particularly limited. For example, a substance containing hydrazines (such as hydrazines or an aqueous solution of hydrazines) may be added in preparing the treatment liquid. Furthermore, a substance containing hydrazines as a trace component (impurity or the like) may be used as a raw material in preparing the treatment liquid so that the hydrazines are introduced into the treatment liquid. 
     &lt;First Anions&gt; 
     The treatment liquid preferably contains one or more kinds of first anions selected from the group consisting of Cl − , NO 2   − , and NO 3   − , more preferably contains two or more kinds of first anions selected from the same group, and even more preferably contains three kinds of first anions selected from the same group. 
     That is, it is preferable that the treatment liquid contain all of Cl − , NO 2   − , and NO 3   − . 
     In the treatment liquid, the total content of the first anions (total content of Cl − , NO 2   − , and NO 3   − ) is preferably 0.00001 to 100 parts by mass with respect to 100 parts by mass of hydroxylamine. 
     In a case where the total content of the first anions is 0.00001 parts by mass or more, the metal residue removability of the treatment liquid is further improved. In a case where the total content of the first anions is 100 parts by mass or less, the smoothness of the object to be treated is further improved. In order that the performances of the treatment liquid are well balanced, the total content of the first anions is, for example, preferably 0.0001 to 30 parts by mass, more preferably 0.1 to 25 parts by mass, and even more preferably 0.1 to 10 parts by mass. 
     The inventors of the present invention consider that in a case where the treatment liquid contains anions as described above, the effects of the treatment liquid may be further improved for the following reason. 
     That is, in a case where the first anions are in water in the treatment liquid according to the aspect of the present invention, the anions suitably react with metal-containing residues and the like generated after dry etching, which can further improve the solubility of the residues in water and enhance the washing properties. Such an effect is more marked in a case where the total content of the first anions is equal to or more than a predetermined amount with respect to the hydroxylamine. Furthermore, presumably, because the total content of the first anions is equal to or less than a predetermined amount with respect to the hydroxylamine, so-called pitting and corrosion caused in a metal by anions may be suppressed, and the smoothness of the surface after treatment could be improved. 
     In the treatment liquid, the total content of the first anions is preferably 0.001 to 50,000 ppm by mass with respect to the total mass of the treatment liquid. 
     In a case where the total content of the first anions is 0.001 ppm by mass or more with respect to the total mass of the treatment liquid, the washing properties of the treatment liquid are further improved. In a case where the total content of the first anions is 50,000 ppm by mass or less with respect to the total mass of the treatment liquid, the smoothness of the object to be treated is further improved. In order that the performances of the treatment liquid are well balanced, the total content of the first anions with respect to the total mass of the treatment liquid is, for example, more preferably 1 to 25,000 ppm by mass, and even more preferably 2 to 15,000 ppm by mass. 
     In the treatment liquid, the content of Cl −  is preferably 0.001 to 5,000 ppm by mass with respect to the total mass of the treatment liquid. 
     In a case where the content of Cl −  is 0.05 ppm by mass or more with respect to the total mass of the treatment liquid, the washing properties of the treatment liquid are further improved. In a case where the content of Cl −  is 5,000 ppm by mass or less with respect to the total mass of the treatment liquid, the smoothness of the object to be treated is further improved. 
     In order that the performances of the treatment liquid are well balanced, the content of Cl −  with respect to the total mass of the treatment liquid is, for example, more preferably 0.05 to 2,000 ppm by mass, and even more preferably 0.1 to 500 ppm by mass. 
     In the treatment liquid, the content of NO 2   −  is preferably 0.001 to 30,000 ppm by mass with respect to the total mass of the treatment liquid. 
     In a case where the content of NO 2   −  is 0.001 ppm by mass or more with respect to the total mass of the treatment liquid, the washing properties of the treatment liquid are further improved. In a case where the content of NO 2   −  is 30,000 ppm by mass or less with respect to the total mass of the treatment liquid, the smoothness of the object to be treated is further improved. In order that the performances of the treatment liquid are well balanced, the content of NO 2   −  with respect to the total mass of the treatment liquid is, for example, more preferably 0.5 to 20,000 ppm by mass, and even more preferably 1 to 5,000 ppm by mass. 
     In the treatment liquid, the content of NO 3   −  is preferably 0.001 to 30,000 ppm by mass with respect to the total mass of the treatment liquid. 
     In a case where the content of NO 3   −  is 0.001 ppm by mass or more with respect to the total mass of the treatment liquid, the washing properties of the treatment liquid are further improved. In a case where the content of NO 3   −  is 30,000 ppm by mass or less with respect to the total mass of the treatment liquid, the smoothness of the object to be treated is further improved. In order that the performances of the treatment liquid are well balanced, the content of NO 3   −  with respect to the total mass of the treatment liquid is, for example, more preferably 0.5 to 20,000 ppm by mass, and even more preferably 1 to 5,000 ppm by mass. 
     Especially, among the first anions, NO 2   −  and NO 3   −  are also called specific anions. 
     The total mass of the two kinds of specific anions consisting of NO 2   −  and NO 3   −  contained in the treatment liquid is preferably 0.001 to 50,000 ppm by mass with respect to the total mass of the treatment liquid. 
     In order that the performances of the treatment liquid are well balanced, the total mass of the specific anions contained in the treatment liquid with respect to the total mass of the treatment liquid is more preferably 1 to 50,000 ppm by mass, and even more preferably 2 to 10,000 ppm by mass. 
     In the treatment liquid, the total mass of the two kinds of specific anions consisting of NO 2   −  and NO 3   −  contained in the treatment liquid is preferably larger than the mass of the Cl −  contained in the treatment liquid. In this case, in the treatment liquid, the content of the Cl −  with respect to the total mass of the treatment liquid is preferably more than 0 ppm by mass, and more preferably 0.001 ppm by mass. 
     For example, a ratio of the total mass of the specific anions contained in the treatment liquid to the mass of the Cl −  contained in the treatment liquid (total mass of specific anions contained in treatment liquid/mass of Cl −  contained in treatment liquid) is preferably 1.1 to 100, and more preferably 1.5 to 30. 
     In the treatment liquid, the content of the first anions preferably satisfies the relationship of “mass of Cl −  contained in treatment liquid ≤mass of NO 2   −  contained in treatment liquid ≤mass of NO 3   −  contained in treatment liquid”, and more preferably satisfies the relationship of “0.001 ppm by mass ≤mass of Cl −  contained in treatment liquid ≤mass of NO 2   −  contained in treatment liquid ≤mass of NO 3   −  contained in treatment liquid”. 
     &lt;Second Anions&gt; 
     The treatment liquid may further contain one or more kinds of second anions selected from the group consisting of SO 4   2−  and PO 4   3− . 
     That is, the treatment liquid may contain either or both of SO 4   2−  and PO 4   3− , or may contain neither of these. 
     In a case where the treatment liquid contains one or more kinds of second anions, the total content of the first anions and the second anions (total content of Cl − , NO 2   − , NO 3   − , SO 4   2− , and PO 4   3− ) is preferably 0.0001 to 30 parts by mass with respect to 100 parts by mass of hydroxylamine. 
     In a case where the total content of the first and second anions is 0.0001 parts by mass or more, the washing properties of the treatment liquid are further improved. In a case where the total content is 30 parts by mass or less, the smoothness of the object to be treated is further improved. In order that the performances of the treatment liquid are well balanced, the total content of the first and second anions is, for example, more preferably 0.1 to 25 parts by mass, and even more preferably 0.1 to 10 parts by mass.

     The method for introducing the first anions and/or the second anions into the treatment liquid is not particularly limited.

     Furthermore, the compounds that produce substances containing the first anions and/or the second anions by dissolution in water, chemical reactions, and the like may be adopted as sources of the first anions and/or the second anions. Examples of such compounds include dinitrogen trioxide which produces nitrous acid by reacting with water.

     &lt;Treatment Liquid Manufacturing Method&gt; 
     The method for manufacturing the treatment liquid is not particularly limited, and known manufacturing methods can be used.

     &lt;Treatment Liquid Container&gt; 
     The treatment liquid may be stored in a container and kept as it is until use. 
     The container and the treatment liquid stored in the container are collectively called treatment liquid container. The stored treatment liquid is used after being taken out of the treatment liquid container. Furthermore, the treatment liquid may be transported as a treatment liquid container. 
     It is preferable to use a container for semiconductors which has a high internal cleanliness and hardly causes elution of impurities. Examples of usable containers include a “CLEAN BOTTLE” series manufactured by AICELLO CORPORATION, and “PURE BOTTLE” manufactured by KODAMA PLASTICS Co., Ltd.

It is also preferable that the inner wall of the container be formed of a metal having undergone a rustproofing treatment or a metal elution preventing treatment, such as stainless steel, Hastelloy, Inconel, or Monel. 
     As “resin different from these” described above, a fluororesin (perfluororesin) is preferable. In a case where a container having inner wall made of a fluororesin is used, the occurrence of problems such as elution of an ethylene or propylene oligomer can be further suppressed, than in a case where a container having inner wall formed of a polyethylene resin, a polypropylene resin, or a polyethylene-polypropylene resin is used. 
     Examples of the container having inner wall made of a fluororesin include a FluoroPure PFA composite drum manufactured by Entegris, and the like. In addition, it is also possible to use the containers described on page 4 of JP1991-502677A (JP-H03-502677A), page 3 of WO2004/016526A, pages 9 and 16 of the WO99/46309A, and the like. 
     Furthermore, in addition to the fluororesin described above, quartz and an electropolished metallic material (that is, a metallic material having undergone electropolishing) are also preferably used for the inner wall of the container. 
     For manufacturing the electropolished metallic material, it is preferable to use a metallic material which contains at least one kind of metal selected from the group consisting of chromium and nickel, and in which the total content of chromium and nickel is more than 25% by mass with respect to the total mass of the metallic material. Examples of such a metallic material include stainless steel and a nickel-chromium alloy. 
     The total content of chromium and nickel in the metallic material is preferably 30% by mass or more with respect to the total mass of the metallic material. 
     The upper limit of the total content of chromium and nickel in the metallic material is not particularly limited, but is preferably 90% by mass or less with respect to the total mass of the metallic material. 
     The stainless steel is not particularly limited, and known stainless steel can be used. Particularly, an alloy with a nickel content of 8% by mass or more is preferable, and austenite-based stainless steel with a nickel content of 8% by mass or more is more preferable. 
     Examples of the austenite-based stainless steel include Steel Use Stainless (SUS) 304 (Ni content: 8% by mass, Cr content: 18% by mass), SUS304L (Ni content: 9% by mass, Cr content: 18% by mass), SUS316 (Ni content: 10% by mass, Cr content: 16% by mass), and SUS316L (Ni content: 12% by mass, Cr content: 16% by mass).

     Furthermore, if necessary, the nickel-chromium alloy may further contain boron, silicon, tungsten, molybdenum, copper, or cobalt, in addition to the aforementioned alloy. 
     The method of electropolishing the metallic material is not particularly limited, and known methods can be used. For example, it is possible to use the methods described in paragraphs “0011” to “0014” in JP2015-227501A, paragraphs “0036” to “0042” in JP2008-264929A, and the like. 
     It is preferable that the metallic material have undergone buffing. As the buffing method, known methods can be used without particular limitation. The size of abrasive grains used for finishing the buffing is not particularly limited, but is preferably #400 or less because such grains make it easy to further reduce the surface asperity of the metallic material. 
     The buffing is preferably performed before the electropolishing. 
     Furthermore, one of the multistage buffing carried out by changing the size of abrasive grains, acid pickling, magnetorheological finishing, and the like or a combination of two or more treatments selected from the above may be performed on the metallic material. 
     It is preferable that the inside of these containers be washed before the containers are filled with the treatment liquid. For washing, it is preferable to use a liquid with a lower metal impurity content. 
     After being manufactured, the treatment liquid may be bottled using a container, such as a gallon bottle or a quart bottle, and transported or stored. 
     In order to prevent changes in the components of the treatment liquid during storage, the inside of the container may be purged with an inert gas (such as nitrogen or argon) having a purity of 99.99995% by volume or higher. Particularly, a gas with a low moisture content is preferable. Although the treatment liquid may be transported and stored at room temperature, in order to prevent deterioration, the temperature may be controlled in a range of −20° C. to 20° C. 
     The treatment liquid may be prepared as a kit composed of a plurality of separated raw materials of the treatment liquid. 
     Furthermore, the treatment liquid may be prepared as a concentrated solution. In a case where the treatment liquid is prepared as a concentrated solution, the concentration factor is appropriately determined depending on the composition, but is preferably 5× to 2,000×. That is, the concentrated solution is used after being diluted 5× to 2,000×. 
     [Method for Treating Object to be Treated] 
     In the method for treating an object to be treated by using the treatment liquid according to an embodiment of the present invention (hereinafter, the method will be also simply described as “the present treatment method”), typically, it is possible to use the treatment liquid by bringing the treatment liquid into contact with an object to be treated containing a metal-based material which is a material containing a metal. In this case, the object to be treated may contain two or more kinds of metal-based materials. Furthermore, it is preferable that the treatment liquid dissolve at least one of the two or more kinds of metal-based materials that may be contained in the object to be treated. 
     The metal-based material may have metal atoms (such as cobalt (Co), ruthenium (Ru), tungsten (W), molybdenum (Mo), aluminum (Al), copper (Cu), titanium (Ti), and/or tantalum (Ta)). Examples thereof include a simple metal, an alloy, a metal oxide (which may be a composite oxide), and a metal nitride (which may be a composite nitride). 
     The content of metal atoms in the metal-based material with respect to the total mass of the metal-based material is preferably 30% to 100% by mass, more preferably 40% to 100% by mass, and even more preferably 52% to 100% by mass. 
     Examples of the metal-based material include a cobalt-containing substance, a metal-containing substance, and the like. Details of the cobalt-containing substance and the metal-containing substance will be described later. 
     For example, it is preferable that at least one of the two or more kinds of metal-based materials that an object to be treated may contain be a cobalt-containing substance, and the treatment liquid is preferably used by being brought into contact with the object to be treated containing a cobalt-containing substance so that the cobalt-containing substance is dissolved (etched). 
     That is, the treatment liquid may be, for example, an etching treatment liquid. 
     It is also preferable that the object to be treated contain a metal-containing substance (hereinafter, also simply called “metal-containing substance”) containing metal atoms other than cobalt atoms (hereinafter, also simply called “other metal atoms”), in addition to the cobalt-containing substance. 
     In this case, the treatment liquid may be used for etching only the cobalt-containing substance, or used for etching both the cobalt-containing substance and metal-containing substance. 
     The form of the object to be treated is not particularly limited. For example, the object may be an object  10  to be treated shown in  FIG.  1    having a substrate  12 , an insulating film  14  with hole portions that is disposed on the substrate  12 , a metal-containing substance portion  16  disposed in the form of a layer along the inner wall of the hole portions of the insulating film  14 , and a cobalt-containing substance portion  18  with which the hole portions are filled. In  FIG.  1   , the metal-containing substance portion can function as a barrier metal layer. 
     Although  FIG.  1    shows an aspect in which the object to be treated has one cobalt-containing substance portion, the object to be treated is not limited to this aspect. For example, the object may be an object  20  to be treated shown in  FIG.  2    having a substrate  12 , an insulating film  14  with a plurality of hole portions that is disposed on the substrate  12 , a metal-containing substance portion  16  disposed in the form of a layer along the inner wall of each of the hole portions of the insulating film  14 , and a cobalt-containing substance portion  18  with which each of the hole portions is filled. That is, the object to be treated may have an aspect in which each of the cobalt-containing substance and the metal-containing substance is at a plurality of sites. 
     The type of substrate that may be contained in the object to be treated is not particularly limited. Examples of the substrate include various substrates such as a semiconductor wafer, a glass substrate for a photomask, a glass substrate for liquid crystal display, a glass substrate for plasma display, a substrate for field emission display (FED), a substrate for an optical disk, a substrate for a magnetic disk, and a substrate for a magneto-optical disk. 
     Examples of materials constituting the semiconductor substrate include silicon, silicon germanium, a Group III-V compound such as GaAs, and any combination of these. 
     The size, thickness, shape, layer structure, and the like of the substrate are not particularly limited, and can be appropriately selected as desired. 
     As the insulating film, known insulating films are used. 
     The insulating film in  FIGS.  1  and  2    has hole portions. However, the insulating film is not limited to this aspect, and may be an insulating film having groove portions. 
     The cobalt-containing substance may have cobalt atoms. Examples of the cobalt-containing substance include simple cobalt (metallic cobalt), a cobalt alloy (preferably an alloy containing cobalt as a metal component taking up the highest mass ratio), a cobalt oxide, and a cobalt nitride. 
     In the cobalt-containing substance, the content of cobalt atoms with respect to the total mass of the cobalt-containing substance is preferably 50% to 100% by mass, more preferably 80% to 100% by mass, and even more preferably 99% to 100% by mass. 
     The type of other metal atoms in the metal-containing substance is not particularly limited, and examples thereof include titanium and tantalum. Particularly, as other metal atoms, metal atoms nobler than cobalt are preferable. 
     The metal-containing substance may contain the aforementioned other metal atoms.

     As the metal-containing substance, in view of further improving the effects of the treatment liquid, simple titanium, a titanium alloy, a titanium oxide, a titanium nitride, simple tantalum, a tantalum alloy, a tantalum oxide, or a tantalum nitride is preferable. 
     In a case where the object to be treated contains the metal-containing substance, the cobalt-containing substance and the metal-containing substance may be in contact with each other in the object to be treated or may be arranged via other members. 
     The forms of the cobalt-containing substance and the metal-containing substance are not particularly limited. For example, these substances may be in the form of a film, wiring, or particles. 
     In a case where the cobalt-containing substance and the metal-containing substance are in the form of a film, the thickness thereof is not particularly limited and may be appropriately selected depending on the use. For example, the thickness is preferably 50 nm or less, more preferably 20 nm or less, and even more preferably 10 nm or less. 
     The cobalt-containing substance and the metal-containing substance may be disposed only on one of the main surfaces of the substrate, or may be disposed on both the main surfaces of the substrate. Furthermore, the cobalt-containing substance and the metal-containing substance may be disposed on the entire main surface of the substrate, or may be disposed on a portion of the main surface of the substrate. 
     The object to be treated may contain two or more kinds of cobalt-containing substances, or may contain two or more kinds of metal-containing substances. 
     Although the object to be treated containing a cobalt-containing substance has been mainly described hitherto as an object to be treated, the object to be treated containing a cobalt-containing substance may contain another metal-based material instead of the cobalt-containing substance. For example, these objects to be treated may contain, instead of the cobalt-containing substance, a ruthenium-containing substance, a tungsten-containing substance, a molybdenum-containing substance, an aluminum-containing substance, or a copper-containing substance. Specifically, the ruthenium-containing substance, the tungsten-containing substance, the molybdenum-containing substance, the aluminum-containing substance, and the copper-containing substance are the same as the cobalt-containing substance described above except that cobalt is substituted with ruthenium, tungsten, molybdenum, aluminum, and copper, respectively. 
     In a case where the object to be treated contains, instead of the cobalt-containing substance, a ruthenium-containing substance, a tungsten-containing substance, a molybdenum-containing substance, an aluminum-containing substance, or a copper-containing substance, “other metal atoms” in the aforementioned metal-containing substance refers to metal atoms other than ruthenium atoms, metal atoms other than tungsten atoms, metal atoms other than molybdenum atoms, metal atoms other than aluminum atoms, and metal atoms other than copper atoms, respectively. Even in this case, as the metal-containing substance, simple titanium, a titanium alloy, a titanium oxide, a titanium nitride, simple tantalum, a tantalum alloy, a tantalum oxide, or a tantalum nitride is preferable. 
     The object to be treated may include various layers and/or structures as desired, in addition to the above components. For example, the substrate may have metal wiring, a gate electrode, a source electrode, a drain electrode, an insulating layer, a ferromagnetic layer, and/or a non-magnetic layer, and the like. 
     The substrate may include the structure of an exposed integrated circuit, for example, an interconnection mechanism such as metal wiring and a dielectric material. Examples of metals and alloys used for the interconnection mechanism include aluminum, a copper-aluminum alloy, copper, titanium, tantalum, cobalt, silicon, titanium nitride, tantalum nitride, and tungsten. The substrate may include a layer of silicon oxide, silicon nitride, silicon carbide, and/or carbon-doped silicon oxide. 
     The method for manufacturing the object to be treated is not particularly limited. For example, the object to be treated shown in  FIG.  1    may be manufactured by a method of forming an insulating film on a substrate, forming hole portions or groove portions in the insulating film, arranging a metal-containing substance layer and a cobalt-containing substance layer in this order on the insulating film by a sputtering method, a chemical vapor deposition (CVD) method, a molecular beam epitaxy (MBE) method, or the like, and then performing a smoothing treatment such as CMP. 
     Examples of the method for treating an object to be treated according to an embodiment of the present invention include a method of bringing an object to be treated containing at least one kind of metal-based material into contact with the treatment liquid described above. By adopting this method, it is possible to dissolve one or more kinds of metal-based materials contained in the object to be treated or to wash the object to be treated (for example, wash dry etching residues contained in the object to be treated). 
     &lt;First Aspect&gt; 
     More specifically, examples of the method for treating an object to be treated according to the embodiment of the present invention include a method of bringing an object to be treated containing at least a cobalt-containing substance into contact with the aforementioned treatment liquid so that the cobalt-containing substance is dissolved. This method for treating an object to be treated is also called a first aspect of the method for treating an object to be treated according to the embodiment of the present invention. 
     The method of bringing the object to be treated into contact with the treatment liquid is not particularly limited, and examples thereof include a method of immersing the object to be treated in the treatment liquid stored in a tank, a method of spraying the treatment liquid onto the object to be treated, a method of causing the treatment liquid to flow on the object to be treated, and a combined method consisting of any of the above methods. Among these, the method of immersing the object to be treated in the treatment liquid is preferable. 
     In order to further enhance the washing ability of the treatment liquid, a mechanical stirring method may also be used. 
     Examples of the mechanical stirring method include a method of circulating the treatment liquid on an object to be treated, a method of causing the treatment liquid to flow on the object to be treated or spraying the treatment liquid onto the object to be treated, and a method of stirring the treatment liquid by using ultrasonic or megasonic waves. 
     The contact time between the object to be treated and the treatment liquid can be adjusted as appropriate. 
     The treatment time (the contact time between the treatment liquid and the object to be treated) is not particularly limited, but is preferably 0.25 to 10 minutes, and more preferably 0.5 to 2 minutes. 
     The temperature of the treatment liquid during the treatment is not particularly limited, but is preferably 20° C. to 75° C. and more preferably 20° C. to 65° C. 
     By the treatment performed as above, mainly the cobalt-containing substance in the object to be treated is dissolved. 
     In a case where the object to be treated contains a metal-containing substance in addition to the cobalt-containing substance, the metal-containing substance may or may not be dissolved together with the cobalt-containing substance by this treatment. In a case where the metal-containing substance is dissolved, the dissolution of the metal-containing substance may be intentional or inevitable. 
     In a case where the dissolution of the metal-containing substance is unintentional, it is preferable that the amount of the inevitably dissolved metal-containing substance be small. In a case where the dissolution of the metal-containing substance is unintentional, and the amount of the inevitably dissolved metal-containing substance is small, the treatment liquid is also described as being excellent in member resistance of the metal-containing substance. 
     In the first aspect, the object to be treated may contain, instead of or in addition to the cobalt-containing substance, a ruthenium-containing substance, a tungsten-containing substance, a molybdenum-containing substance, an aluminum-containing substance, or a copper-containing substance. 
     &lt;Second Aspect&gt; 
     Examples of other aspects of the method for treating an object to be treated according to an embodiment of the present invention include the following second aspect. 
     That is, the second aspect is a method for treating an object to be treated, including a step A of performing an oxidation treatment on an object to be treated having a metal layer so that the surface layer of the metal layer is oxidized and turns into a metal oxide layer and a step B of bringing the object to be treated obtained by the step A into contact with the treatment liquid so that the metal oxide layer is dissolved. 
     The second aspect may be a form of the first aspect. 
     The metal layer is a form of metal-based material which is a layer consisting of a metal-based material that can be oxidized. The metal layer is preferably, for example, a simple metal or a metal alloy. The metal layer is preferably a cobalt-containing substance (such as simple cobalt or a cobalt alloy), a ruthenium-containing substance (such as simple ruthenium or a ruthenium alloy), a tungsten-containing substance (such as simple tungsten or a tungsten alloy), a molybdenum-containing substance (such as simple molybdenum or a molybdenum alloy), an aluminum-containing substance (such as simple aluminum or an aluminum alloy), or a copper-containing substance (such as simple copper or a copper alloy), and more preferably a cobalt-containing substance (simple cobalt or a cobalt alloy). 
     The metal oxide layer is a layer formed by the oxidation of the surface layer of the metal layer, and can be said to be a form of metal-based material. A part of the surface layer of the metal layer may turn into a metal oxide layer, or the entire surface layer of the metal layer may turn into a metal oxide layer. 
     The metal oxide layer is an oxide of a simple metal or alloy. The metal oxide layer is preferably a layer consisting of a cobalt oxide, an oxide of a cobalt alloy, a ruthenium oxide, an oxide of a ruthenium alloy, a tungsten oxide, an oxide of a tungsten alloy, a molybdenum oxide, an oxide of a molybdenum alloy, an aluminum oxide, an oxide of an aluminum alloy, a copper oxide, or an oxide of a copper alloy, more preferably a layer consisting of a cobalt oxide or an oxide of a cobalt alloy, and even more preferably a layer consisting of a cobalt oxide. 
     The thickness of the metal oxide layer is, for example, equivalent to the thickness of 1 to 10 atomic layers. The thickness of one atomic layer of a metal or metal oxide is 1 nm or less (for example, 0.3 nm to 0.4 nm). That is, the oxidation treatment is a treatment of forming a metal oxide layer by oxidizing the surface layer of the metal layer, for example, by a thickness of 1 to 10 atomic layers. 
     In many cases, the metal oxide layer is more soluble (more easily etched) in the treatment liquid than the metal layer. 
     That is, in the second aspect, by making the surface of the metal layer into a thin metal oxide layer in the step A and removing only the metal oxide layer (and the portion where the metal layer under the metal oxide layer can be inevitably dissolved) by using the treatment liquid in the step B, it is possible to remove (dissolve) only the extremely thin surface of the metal layer contained in the object to be treated. 
     Furthermore, by alternately repeating the step A and the step B, it is possible to control the etching amount with high accuracy. 
     In a case where the step A and the step B are performed alternately, it is preferable that each of the step A and the step B be performed 1 to 20 times. 
     The object to be treated to which the second aspect can be applied may have only one kind of metal layer or two or more kinds of metal layers. Furthermore, the object to be treated to which the second aspect can be applied may contain a metal-based material other than the metal layer or the metal oxide layer, and a part or entirety of such a metal-based material may be intentionally or inevitably removed through the step A and the step B. 
     The step A is a step of performing an oxidation treatment on the object to be treated having the metal layer so that the surface layer of the metal layer is oxidized and turns into a metal oxide layer. 
     There are no restrictions on the method of oxidation treatment for oxidizing the surface layer of the metal layer to form a metal oxide layer. For example, the oxidation treatment can be performed by a liquid treatment of bringing the object to be treated into contact with an oxidizing solution, a gas treatment of bringing the object to be treated into contact with an oxidizing gas (such as an ozone treatment of bringing the object to be treated into contact with an ozone gas or a heating treatment in oxygen in which the object to be treated is heated in an oxygen atmosphere that will be described later), or a plasma treatment using an oxygen gas. 
     One kind of oxidation treatment may be performed, or two or more kinds of oxidation treatments may be performed. 
     Particularly, as the oxidation treatment, it is preferable to perform at least a liquid treatment of bringing a predetermined solution into contact with the aforementioned object to be treated. 
     The aforementioned oxidizing solution may be a solution that can oxidize the surface layer of the metal layer. The oxidizing solution is preferably a solution other than the treatment liquid according to an embodiment of the present invention. 
     The aforementioned oxidizing solution is preferably a solution (hereinafter, also called “specific solution”) selected from the group consisting of water, hydrogen peroxide water, a mixed aqueous solution of ammonia and hydrogen peroxide (APM), a mixed aqueous solution of hydrofluoric acid and hydrogen peroxide water (FPM), a mixed aqueous solution of sulfuric acid and hydrogen peroxide water (SPM), a mixed aqueous solution of hydrochloric acid and hydrogen peroxide water (HPM), water containing dissolved oxygen, water containing dissolved ozone, perchloric acid, and nitric acid. 
     Among these, a solution selected from the group consisting of water, hydrogen peroxide water, APM, FPM, SPM, HPM, water containing dissolved oxygen, and water containing dissolved ozone is preferable as the specific solution. 
     The hydrogen peroxide water has a composition in which, for example, the content of H 2 O 2  is 0.5% to 31% by mass with respect to the total mass of the hydrogen peroxide water. The content of H 2 O 2  is more preferably 3% to 15% by mass. 
     The composition of APM is, for example, preferably in a range of “aqueous ammonia:hydrogen peroxide water:water=1:1:1” to “aqueous ammonia:hydrogen peroxide water:water=1:3:45” (mass ratio). 
     The composition of FPM is, for example, preferably in a range of “hydrofluoric acid:hydrogen peroxide water:water=1:1:1” to “hydrofluoric acid:hydrogen peroxide water:water=1:1:200” (mass ratio). 
     The composition of SPM is, for example, preferably in a range of “sulfuric acid:hydrogen peroxide water:water=3:1:0” to “sulfuric acid:hydrogen peroxide water:water=1:1:10” (mass ratio). 
     The composition of HPM is, for example, preferably in a range of “hydrochloric acid:hydrogen peroxide water:water=1:1:1” to “hydrochloric acid:hydrogen peroxide water:water=1:1:30” (mass ratio). 
     The preferred compositional ratio described above means a compositional ratio determined in a case where the content of aqueous ammonia is 28% by mass, the content of hydrofluoric acid is 49% by mass, the content of sulfuric acid is 98% by mass, the content of hydrochloric acid is 37% by mass, and the content of hydrogen peroxide water is 30% by mass. 
     Furthermore, the volume ratio is based on a volume at room temperature. 
     “A:B:C=x:y:z to A:B:C=X:Y:Z” used above to describe a suitable range means that it is preferable that at least one (preferably two and more preferably all) of “A:B=x:y to A:B=X:Y”, “B:C=y:z to B:C=Y:Z”, or “A:C=x:z to A:C=X:Z” be satisfied. 
     The water containing dissolved oxygen is an aqueous solution having a composition in which, for example, the content of O 2  is 1 to 200 ppm by mass with respect to the total mass of the water containing dissolved oxygen. 
     The water containing dissolved ozone is an aqueous solution having a composition in which, for example, the content of O 3  is 1 to 200 ppm by mass with respect to the total mass of the water containing dissolved ozone. 
     Perchloric acid is, for example, an aqueous solution in which the content of HClO 4  is 0.001% to 60% by mass with respect to the total mass of the solution. 
     Nitric acid is, for example, an aqueous solution in which the content of HNO 3  is 0.001% to 60% by mass with respect to the total mass of the solution. 
     In the liquid treatment, the method of bringing the object to be treated into contact with the oxidizing solution (preferably the specific solution) is not particularly limited. Examples of the method include a method of immersing the object to be treated in the oxidizing solution stored in a tank, a method of spraying the oxidizing solution onto the object to be treated, a method of causing the oxidizing solution to flow on the object to be treated, and a combined method consisting of any of the above methods. 
     The contact time between the object to be treated and the oxidizing solution is, for example, preferably 0.25 to 10 minutes, and more preferably 0.5 to 5 minutes. 
     The temperature of the oxidizing solution is preferably 20° C. to 75° C., and more preferably 20° C. to 60° C. 
     Examples of the oxidizing gas to be brought into contact with the object to be treated in the gas treatment include dry air, an oxygen (02) gas, an ozone (03) gas, and a mixed gas of these. The oxidizing gas may contain a gas other than these gases. 
     The oxidizing gas to be brought into contact with the object to be treated in the gas treatment is particularly preferably an oxygen gas or an ozone gas. In a case where an oxygen gas or an ozone gas is brought into contact with the object to be treated, it is also preferable that the contact be made in an oxygen atmosphere, an ozone atmosphere, or an atmosphere of a mixed gas of oxygen and ozone. 
     In the gas treatment, it is also preferable to heat the object to be treated (for example, heat the object to be treated at 40° C. to 200° C.) while bringing the object to be treated into contact with an oxidizing gas. 
     The gas treatment is particularly preferably an ozone treatment of bringing an ozone gas into contact with the object to be treated or a heating treatment in oxygen in which the object to be treated is heated in an oxygen atmosphere. 
     In the ozone treatment, an ozone gas may be brought into contact with the object to be treated in an ozone atmosphere, or an ozone gas may be brought into contact with the object to be treated in an atmosphere of a mixed gas of an ozone gas and another gas (for example, an oxygen gas). Furthermore, the ozone treatment may be a treatment of heating the object to be treated while bringing the object to be treated into contact with an ozone gas. 
     In step A (particularly in a case where the liquid treatment is performed), the object to be treated may contain a metal-based material other than the metal layer having surface layer that is oxidized by the oxidation treatment and turns into a metal oxide layer, and a part or entirety of such a metal-based material may be intentionally or inevitably removed by the step A (particularly by the liquid treatment). 
     Furthermore, in the step A (particularly in a case where the liquid treatment is performed), a part of the metal layer of the object to be treated may be intentionally or inevitably removed. 
     The step B is a step of bringing the object to be treated obtained by the step A into contact with a treatment liquid so that the metal oxide layer is dissolved. 
     The method of bringing the object to be treated into contact with the treatment liquid in step B is not limited, and examples thereof are the same as the examples of the method of bringing the object to be treated into contact with an oxidizing solution. 
     The contact time between the object to be treated and the treatment liquid is, for example, preferably 0.25 to 10 minutes, and more preferably 0.5 to 5 minutes. 
     The temperature of the treatment liquid is preferably 20° C. to 75° C., and more preferably 20° C. to 60° C. 
     In the step B, the metal oxide layer may be partially or totally removed. 
     In the step B, a part or entirety of the metal layer (for example, the metal layer which is exposed on the surface layer by the removal of the metal oxide layer covering the surface) may be intentionally or inevitably removed. 
     In the step B, the object to be treated may contain a metal-based material other than the metal oxide layer and the metal layer forming a metal oxide layer on the surface, or a part or entirety of such a metal-based material may be intentionally or inevitably removed. 
     In a case where the dissolution of the metal layer and/or other metal-based materials is unintended, it is preferable that the amount of the metal layer and/or other metal-based materials to be inevitably dissolved be small. 
     The treatment liquid to be used in the step B may be subjected to a deaeration treatment in advance so that the amount of dissolved oxygen is reduced. In a case where the amount of dissolved oxygen in the treatment liquid is reduced, it is possible to suppress a phenomenon where the metal layer exposed by the removal of the metal oxide layer with the treatment liquid is oxidized due to the dissolved oxygen in the treatment liquid and turns into a new metal oxide layer, such a metal oxide layer is removed again by the treatment liquid, and thus an excess of metal layer is removed. 
     &lt;Third Aspect&gt; 
     Examples of another aspect (third aspect) of the method for treating an object to be treated according to an embodiment of the present invention include an aspect in which an object to be treated containing a metal-based material is subjected to a dry etching treatment and then brought into contact with a treatment liquid so that dry etching residues are removed. 
     The object to be treated in the present aspect may contain only one kind of metal-based material or two or more kinds of metal-based materials. At least one kind of metal-based material or at least one of the two or more kinds of metal-based materials is preferably a cobalt-containing substance, a ruthenium-containing substance, a molybdenum-containing substance, an aluminum-containing substance, or a copper-containing substance, and is more preferably a cobalt-containing substance. 
     That is, as the third aspect of the method for treating an object to be treated according to an embodiment of the present invention, an aspect is preferable in which an object to be treated containing a cobalt-containing substance containing cobalt atoms is subjected to a dry etching treatment and then brought into contact with a treatment liquid so that dry etching residues are removed. 
     In the present aspect, the object to be treated that is brought into contact with the treatment liquid contains a metal-based material. Furthermore, in the present aspect, the object to be treated is brought into contact with the treatment liquid after being subjected to the dry etching treatment. Therefore, at a point in time when the object to be treated is brought into contact with the treatment liquid, the object to be treated contains dry etching residues on the surface. In the present aspect, the dry etching residues existing on the surface of such an object to be treated are removed. 
     This method for treating an object to be treated is also called a third aspect of the method for treating an object to be treated according to the embodiment of the present invention. 
     The third aspect may be a form of the first aspect described above that is accomplished by specifically restricting the constitution of the object to be treated and the purpose of the treatment in the first aspect. 
     The treatment liquid according to the embodiment of the present invention can also be suitably used for washing the object to be treated (for removing residues) as described above. 
       FIG.  3    is a schematic view showing an example of the object to be treated (object to be treated after the dry etching treatment) in the third aspect described above. 
     An object  30  to be treated shown in  FIG.  3    comprises a metal-containing film  34 , an etch stop layer  36 , an interlayer insulating film  38 , a metal hard mask  40  in this order on a substrate  32 . Through a dry etching step or the like, a hole  42  exposing the metal-containing film  34  is formed at a predetermined position. That is, the object to be treated shown in  FIG.  3    is a laminate which comprises the substrate  32 , the metal-containing film  34 , the etch stop layer  36 , the interlayer insulating film  38 , and the metal hard mask  40  in this order and comprises the hole  42  that extends from the surface of the metal hard mask  40  to the surface of the metal-containing film  34  at the position of the opening portion of the metal hard mask  40 . An inner wall  44  of the hole  42  is constituted with a cross-sectional wall  44   a  which includes the etch stop layer  36 , the interlayer insulating film  38 , and the metal hard mask  40 , and a bottom wall  44   b  which includes the exposed metal-containing film  34 . A dry etching residue  46  is attached to the inner wall  44 . 
     The metal hard mask in the object to be treated may turn into a barrier metal after the object to be treated is further processed. In other words, the layer that will turn into a barrier metal in the subsequent step may be used as a metal hard mask in the dry etching step. That is, the barrier metal may be used as a metal hard mask. 
     For example, it is preferable that at least one of the metal-containing film  34  or the metal hard mask  40  be the cobalt-containing substance. Especially, it is preferable that the metal-containing film  34  and the metal hard mask  40  be the cobalt-containing substance and the metal-containing substance respectively, or that the metal-containing film  34  and the metal hard mask  40  be the metal-containing substance and the cobalt-containing substance respectively. 
     It is particularly preferable that the metal-containing film  34  and the metal hard mask  40  be the cobalt-containing substance and the metal-containing substance respectively. 
     As the interlayer insulating film, known materials can be used. 
     The dry etching residues may be organic residues containing an organic substance as a main component. The organic residues are residues having an organic substance content of 50% by mass or more. The organic residues may be residues that substantially do not contain a metal-containing substance and/or a cobalt-containing substance. 
     The dry etching residues may contain a metal component as a main component, or may be metal residues containing a metal-containing substance and/or a cobalt-containing substance. The metal residues are residues having a metal component content of more than 50% by mass. The metal residues may be residues that substantially do not contain an organic substance. 
     Examples of the specific method of the third aspect include a method of bringing the aforementioned object to be treated into contact with the treatment liquid. 
     The method of bringing the object to be treated into contact with the treatment liquid is the same as the method described above in the first aspect. 
     By the method of bringing the object to be treated into contact with the treatment liquid, the dry etching residues on the object to be treated are removed. In this case, a metal-based material (such as a cobalt-containing substance which is preferably a cobalt-containing substance as the metal-containing film  34 ) may be dissolved as well. In this case, there is no restriction on the amount of the metal-based material (such as the cobalt-containing substance) dissolved. The dissolution of the metal-based material (such as the cobalt-containing substance) may be intentional dissolution for removing a part or all of the metal-containing film  34  (such as a cobalt-containing substance) on the bottom wall  44   b  of the hole  42 , or inevitable dissolution resulting from the contact between the treatment liquid and the metal-based material (such as the cobalt-containing substance). 
     If necessary, the present treatment method may include a rinsing step of performing a rinsing treatment on the object to be treated by using a rinsing liquid. 
     For example, the method for treating an object to be treated in the first aspect, the second aspect, or the third aspect described above may further include the rinsing step after the procedure described above in each aspect. 
     Furthermore, the present treatment method may include the rinsing step between the step A and the step B in the second aspect.

     The preferred conditions required to FPM, SPM, APM, and HPM are the same as the preferred conditions required, for example, to FPM, SPM, APM, and HPM used as the specific solution described above. 
     The hydrofluoric acid, nitric acid, perchloric acid, and hydrochloric acid mean aqueous solutions obtained by dissolving HF, HNO 3 , HClO 4 , and HCl in water respectively. 
     The aqueous ozone, aqueous carbon dioxide, and aqueous hydrogen mean aqueous solutions obtained by dissolving O 3 , CO 2 , and H 2  in water respectively. 
     As long as the purpose of the rinsing step is not impaired, these rinsing liquids may be used by being mixed together. The rinsing liquid may also contain an organic solvent. 
     Examples of the specific method of the rinsing step include a method of bringing the rinsing liquid into contact with the object to be treated. 
     The method of bringing the rinsing liquid into contact with the object to be treated is performed by a method of immersing the substrate in the rinsing liquid stored in a tank, a method of spraying the rinsing liquid onto the substrate, a method of causing the rinsing liquid to flow on the substrate, or a combined method consisting of any of the above methods. 
     The treatment time (contact time between the rinsing liquid and the object to be treated) is not particularly limited, but is 5 seconds to 5 minutes for example. 
     The temperature of the rinsing liquid during the treatment is not particularly limited. Generally, the temperature of the rinsing liquid is, for example, preferably 16° C. to 60° C., and more preferably 18° C. to 40° C. In a case where SPM is used as the rinsing liquid, the temperature thereof is preferably 90° C. to 250° C. 
     If necessary, the present treatment method may include a drying step of performing a drying treatment after the rinsing step. The method of the drying treatment is not particularly limited, and examples thereof include spin drying, causing a drying gas to flow on the substrate, heating the substrate by a heating unit such as a hot plate or an infrared lamp, isopropyl alcohol (IPA) vapor drying, Marangoni drying, Rotagoni drying, and any combination of these. 
     The drying time varies with the specific method to be used, but is about 30 seconds to a few minutes in general. 
     The present treatment method may be performed in combination with a semiconductor device manufacturing method, before or after the steps performed in the manufacturing method. While being performed, the present treatment method may be incorporated into those other steps. Alternatively, while those other steps are being performed, the present treatment method may be incorporated into the steps and performed. 
     Examples of those other steps include a step of forming each structure such as metal wiring, a gate structure, a source structure, a drain structure, an insulating layer, a ferromagnetic layer and/or a non-magnetic layer (layer formation, etching, chemical mechanical polishing, modification, and the like), a step of forming resist, an exposure step and a removing step, a heat treatment step, a washing step, an inspection step, and the like. 
     The present treatment method may be performed in the back end process (BEOL: Back end of the line) or in the front end process (FEOL: Front end of the line). 
     In addition, the treatment liquid may be applied, for example, to NAND, dynamic random access memory (DRAM), static random access memory (SRAM), resistive random access memory (ReRAM), ferroelectric random access memory (FRAM (registered trademark)), magnetoresistive random access memory (MRAM), phase change random access memory (PRAM), or the like, or applied to a logic circuit, a processor, or the like.

     A multilayer substrate was prepared which consisted of a substrate and a resist film, a metal hard mask (TiN layer), an etching stop layer (Al 2 O 3  layer), a Co layer, and an interlayer insulating layer (ILD) that were laminated in this order on the surface of the substrate. This multilayer substrate was subjected to a patterning treatment by lithography, an etching treatment using a plasma etching machine for metals, and a resist film removal treatment by oxygen plasma ashing, thereby preparing a multilayer substrate for evaluation test (hereinafter, the multilayer substrate will be also described as “test piece”). 
     The obtained test piece was washed (treated) with the treatment liquid of each of the examples and comparative examples. 
     Specifically, first, a glass beaker having a volume of 500 mL was filled with 200 mL of the treatment liquid. In a state where the treatment liquid was being stirred with a stirrer, the temperature of the treatment liquid was raised to 40° C. Then, the test piece prepared as above was immersed for 5 minutes in the treatment liquid at a liquid temperature of 40° C. that was being stirred, so that the test piece was washed. While being immersed in the treatment liquid, the test piece was held using 4-inch long plastic locking forceps so that a surface on a side of the test piece from which the photoresist had been removed faced the stirrer. 
     After a lapse of washing time, the test piece was immediately taken out of the treatment liquid and put in a 400 mL of deionized water (water temperature 17° C.) being gently stirred in a plastic beaker having a volume of 500 mL. The test piece was immersed in the deionized water for 30 seconds, then immediately taken out, and rinsed in running deionized water at 17° C. for 30 seconds. 
     Subsequently, the test piece was exposed to a nitrogen gas stream so that the liquid droplets having adhered to the surface of the test piece were blown away and the surface of the test piece was dried. 
     After this nitrogen drying step, the test piece was removed from the holding part of the plastic forceps, put in a plastic storage box with a lid with the element surface facing up, and stored. 
     By X-ray Photoelectron Spectroscopy (XPS), the composition of the surface of the obtained test piece was analyzed. The surface of the obtained test piece was measured using an XPS device (manufactured by ULVAC-PHI, INCORPORATED, trade name: Quantera SXM). The amounts of carbon atoms contained in the organic residues of the test piece, the amounts of carbon atoms being measured before and after the treatment, were compared with each other, and the rate of reduction caused through the treatment was calculated and adopted as an organic residue removal rate. The organic residue removability of each treatment liquid was evaluated according to the following evaluation standard. 
     1: The organic residue removal rate is 95% or more. 
     2: The organic residue removal rate is 80% or more and less than 95%. 
     3: The organic residue removal rate is 75% or more and less than 80%. 
     4: The organic residue removal rate is 50% or more and less than 75%. 
     5: The organic residue removal rate is less than 50%. 
     &lt;Evaluation on Stability&gt; 
     Next, a storage test was performed using the treatment liquid of each of the examples and comparative examples, and the temporal stability of the removal performance of each treatment liquid was evaluated. 
     Specifically, first, a high-density polyethylene container having a volume of 250 mL was filled with 200 mL of each treatment liquid and sealed. The container filled with the treatment liquid was stored in an environment at 60° C. for 24 hours (storage treatment). 
     The organic residue removability was evaluated and tested according to the same evaluation method of organic residue removability described above, except that the treatment liquid having undergone the storage treatment was used. On the assumption that the organic residue removal rate determined using a treatment liquid not yet being subjected to the storage treatment is 100%, the retention rate of the organic residue removal rate determined using a treatment liquid having undergone the storage treatment (=organic residue removal rate determined using treatment liquid having undergone storage treatment]÷[organic residue removal rate determined using treatment liquid not yet being subjected to storage treatment]×100) was calculated. The obtained retention rate was classified according to the following evaluation standard, and the stability of each treatment liquid was evaluated. 
     It should be noted that the retention rate did not exceed 100% regardless of which treatment liquid was used. 
     1: The retention rate is 99% or more. 
     2: The retention rate is 95% or more and less than 99%. 
     3: The retention rate is 85% or more and less than 95%. 
     4: The retention rate is 75% or more and less than 85%. 
     5: The retention rate is less than 75%. 
     &lt;Evaluation on Smoothness (Smoothness of Object to be Treated)&gt; 
     Substrates were prepared in which a metallic cobalt layer was formed on one surface of a commercial silicon wafer (diameter: 12 inches) by a chemical vapor deposition (CVD) method. The thickness of the metallic cobalt layer was 20 nm. 
     The obtained substrate was immersed in water at 40° C. for 1 minute, and then immersed in each of the treatment liquids shown in the table at 40° C. for 30 seconds. This treatment was regarded as one cycle, and the substrate was treated by repeating this cycle until the metallic cobalt was dissolved by 10 nm. 
     Then, after the treatment, the surface of the metallic cobalt layer was observed with a scanning electron microscope, and the smoothness of the portion treated with the treatment liquid was evaluated on a scale of 1 to 10. 
     The smoothness rated “1” is the best. The larger the rating scale, the worse the smoothness. Specifically, in a case where the surface of the metallic cobalt layer was found to be smooth and no roughness was found as a result of observation, the smoothness of the object to be treated in the treatment liquid was rated “1”. In addition, as the rating scale was getting close to “10”, roughness was further observed, and the metallic cobalt layer was evaluated as having a rougher surface. The smoothness rated “1 to 8” is at a practically preferably usable level, the smoothness rated “9” is at a practically usable level, and the smoothness rated “10” is at a level problematic for practical use. 
     &lt;Evaluation on Metal Residue Removability&gt; 
     An object to be treated (untreated laminate) comprising a metallic cobalt layer, a SiN film, a SiO 2  film, and a barrier metal (TaN) having a predetermined opening portion on a substrate (Si) in this order was formed. By using the barrier metal as a mask, plasma etching (dry etching) was performed on the obtained object to be treated. The SiN film and the SiO 2  film were etched until the metallic cobalt layer was exposed and via holes were formed, thereby manufacturing a sample 1 (see  FIG.  3   ). The cross section of the laminate was checked using SEM/EDX (scanning electron microscope with energy-dispersive X-ray spectroscopy). As a result, plasma etching residues (metal residues) containing, as a main component, a metal such as cobalt on the wall surface of the holes were observed. 
     Then, by the following procedure, metal residue removability was evaluated. First, a section (about 2.0 cm×2.0 cm) of the prepared sample 1 was immersed for 1 minute in (treated with) each treatment liquid controlled to have a temperature of 40° C. After the lapse of a predetermined time, the section of the sample 1 was taken out, immediately washed with ultrapure water, and dried with N 2 . 
     Thereafter, the surface of the section of the sample 1 having undergone immersion was observed with SEM/EDX, and the removability for the aforementioned metal residues was evaluated on a scale of 1 to 10. 
     The washing properties rated “1” are the best. The larger the rating scale, the worse the washing properties. Specifically, in a case where the metal residues were found to be completely removed as a result of observation, the washing properties were rated “1”, and in a case where the metal residues were found to be substantially unremoved, the washing properties were rated “10”. The washing properties rated “1 to 6” are at a practically preferably usable level, the washing properties rated “7 to 9” are at a practically usable level, and the washing properties rated “10” are at a level problematic for practical use. 
     Particularly, in view of balance between performances, it is preferable that the metal residue removability be rated 1 to 6 and the smoothness be rated 1 to 8. 
     [Result] 
     The following Tables 1a-1 to 1n-1 and Tables 1a-2 to 1n-2 show the formulation of the treatment liquids used in the series of test X and the test results. 
     In the tables, “%” means “% by mass”, and “ppm” means “ppm by mass”. 
     The column of “HA (%)” shows the content (% by mass) of hydroxylamine in each treatment liquid with respect to the total mass of the treatment liquid. 
     In the columns of “Chelating agent/Content”, “Benzotriazole compound/Content”, and “Organic solvent/Content”, the upper row shows the type of each component added, and the lower row shows the amount (% by mass) of each component added. 
     The column of “Hydrazines (with respect to 100 parts of HA)” shows the total content (parts by mass) of the hydrazines with respect to 100 parts by mass of hydroxylamine in each treatment liquid. In a case where two kinds of hydrazines were used, the masses the two kinds of hydrazines contained in the treatment liquid were adjusted so that the masses were equal. 
     The column of “Anions (ppm)” shows the content (ppm by mass) of each anion in each treatment liquid with respect to the total mass of the treatment liquid. 
     The column of “Content of first anions (with respect to 100 parts of HA)” shows the total content (parts by mass) of the first anions with respect to 100 parts by mass of hydroxylamine in each treatment liquid. 
     The column of “Content of first and second anions (with respect to 100 parts of HA)” shows the total content (parts by mass) of the first anions and the second anions with respect to 100 parts by mass of hydroxylamine in each treatment liquid. 
     The column of “pH” shows the pH of each treatment liquid. 
     The components (remainder) of each treatment liquid that are not shown in the table consist of a pH adjuster added to achieve a predetermined pH and water. 
     Tables 1a-1 shows the formulation of the treatment liquids of Examples 001 to 049, and Table 1a-2 shows the test results obtained from the treatment liquids of the same examples. 
     For example, in the treatment liquid of Example 001, the content of hydroxylamine is 0.1% by mass with respect to the total mass of the treatment liquid, the content of hydrazine as hydrazines is 0.001 ppm by mass with respect to the total mass of the treatment liquid (0.0001 parts by mass with respect to 100 part by mass of hydroxylamine), none of the first anions, second anions, chelating agent, anticorrosive, and organic solvent are contained in the treatment liquid, and the remainder is a pH adjuster and water added to achieve a pH of 9. Regarding the test results obtained from the treatment liquid of Example 001, the organic residue removability is rated 3, the stability is rated 1, the metal residue removability is rated 9, and the smoothness is rated 3. 
     Tables 1b-1 and the subsequent tables and Table 1b-2 and the subsequent tables can be interpreted in the same way.

     From the results shown in the table, it has been confirmed that in a case where the treatment liquid according to the aspect of the present invention is used, the objects of the present invention can be achieved. 
     In addition, it has been confirmed that in a case where the content of hydrazines is 0.0001 parts by mass or more (preferably 0.005 to 0.5 parts by mass) with respect to 100 parts by mass of hydroxylamine, the effects of the treatment liquid are further improved (refer to the comparison of results of Examples 001 to 005, the comparison of results of Examples 001 and 011, and the like). 
     It has been confirmed that in a case where hydrazines contain hydrazine, the effects of the treatment liquid are further improved (refer to the comparison of results of Examples 014 and 020 to 027, and the like). 
     It has been confirmed that in a case where treatment liquid contains the first anions, the effects of the treatment liquid are further improved (refer to the comparison of results of Examples 009 and 036 to 045, and the like). 
     Furthermore, it has been confirmed that the effects of the treatment liquid are further improved in a case where the total content of the first anions and the second anions is 0.0001 to 30 parts by mass with respect to 100 parts by mass of hydroxylamine (refer to the comparison of the results of Examples 009 and 036 to 045, and the like). 
     It has been confirmed that the effects of the treatment liquid are further improved in a case where the total mass of the two kinds of specific anions consisting of NO 2   −  and NO 3   −  contained in the treatment liquid is larger than the mass of the Cl −  contained in the treatment liquid (refer to the comparison between the result of Example 056 and the result of Example 057, and the like). 
     It has been confirmed that the effects of the treatment liquid are further improved in a case where the treatment liquid contains a chelating agent (more preferably diethylenetriaminepentaacetic acid or citric acid) (refer to the comparison between the results of Examples 093 to 155 and the results of Examples 055, 056, 063, 064, 070, 071, and 072, and the like). 
     It has been confirmed that the effects of the treatment liquid are further improved in a case where the treatment liquid contains an anticorrosive (more preferably benzotriazole, 1-amino-benzotriazole, or 5-methyl-1H-benzotriazole, and even more preferably 5-methyl-1H-benzotriazole) (refer to the comparison between the results of Examples 156 to 204 and the results of Examples 055, 056, 063, 064, 070, 071, and 072, and the like). 
     It has been confirmed that the effects of the treatment liquid are further improved in a case where the treatment liquid contains one or more kinds of organic solvents (more preferably ethylene glycol monobutyl ether) selected from the group consisting of an alcohol-based solvent, a ketone-based solvent, an ester-based solvent, and an ether-based solvent (refer to the comparison between the results of Examples 205 to 372 and the results of Examples 055, 056, 063, 064, 070, 071, and 072, and the like).
