     BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     The present invention relates generally to the semiconductor processing equipment, and more particularly, containment of semiconductor processing fluid and reducing potential sources of contamination from processing fluid interaction with the processing equipment.  
         [0004]     2. Description of the Related Arts  
         [0005]     In the field of semiconductor processing, processing equipment can expose substrates to a variety of processing fluids that are highly reactive. The reactive nature of the processing fluids can result in contamination of the substrate and decreased yields. To contain the processing fluids, processing equipment using the processing fluids can be positioned within a chamber body fabricated from non-reactive plastics. The use of non-reactive plastics provides a chamber body that can minimize a source of contamination should the chamber body is exposed to the processing fluids. While plastics can reduce possible sources of contamination, a chamber body fabricated using plastics may not be as robust as a chamber body fabricated using metals. However, using a metallic chamber body may increase the likelihood of contaminating the substrate if the metallic chamber body is exposed to the processing fluids. In view of the forgoing, there is a need for a robust, non-reactive chamber body.

     DETAILED DESCRIPTION  
       [0022]     An invention is described for improving the chemical resistance of a chamber body for use during semi-conductor substrate processing. The embodiments of the present invention enable a chamber body to be made of any size, and specifically, larger than single substrate chambers, without compromising the structural integrity and resistivity to chemicals designed for use in the chamber. Today&#39;s feature sizes, which continue to shrink into the nanometer range and smaller, require the minimization of potential sources of contamination. Wafer processes utilizing highly reactive chemicals such as hydrofluoric acid (referred to as HF) are conducted in chamber bodies composed of materials that do not produce detrimental contamination when exposed to HF. For example, forming a chamber body from plastics such as polyvinylchloride (PVC) and polytetrafluoroethylene (PTFE) reduces the possibility of contamination because the materials are non-reactive in the presence of HF. However, forming large chamber bodies from plastics can be expensive, difficult and not necessarily geometrically nor statically stable enough to accommodate the precision tolerances required in semiconductor processing. The use of non-plastics such as metals, ceramics, and composite materials for the chamber body can alleviate the geometric and stability problems that can be associated with large plastic chamber bodies. However, HF and other reactive chemicals can react with a metallic chamber body and result in detrimental contamination of the wafer.  
         [0023]     As will be discussed below, a coating of HF resistant material on top of a non-plastic chamber body can alleviate the potential of the non-plastic chamber to detrimentally contaminate the wafer. A non-plastic chamber body with a HF resistant coating can be used for single-wafer wet clean processes. These single-wafer wet clean processes can have several stages, and thus, the chamber body may be relatively large. It will be obvious to one skilled in the art that the present invention may be practiced without some, or all, of these specific details. In other instances, well known process operations have not been described in detail in order not to unnecessarily obscure the present invention.  
         [0024]      FIG. 1  is a simplified diagram of a high level overview of a system for processing semiconductor substrates in accordance with one embodiment of the present invention. As shown in  FIG. 1 , a clean room  100  houses a semiconductor processing unit  118 . The semiconductor processing unit  118  contains a processing chamber  102  and an ancillary chamber  116 . The processing chamber  102  includes a chamber body  104  that is used to contain semiconductor processes such as, but not limited to, plating  110  and wet cleaning  112 . As shown, the wet clean can be of different forms. For instance, a spin-type system may be used or a proximity head system that uses a fluid meniscus may be used. Within the chamber body  104  a wafer carrier  108  can transport a wafer  106  so the semiconductor processes can be performed on the wafer  106 .  
         [0025]     The clean room  100  can have input lines  114  that supply power and processing fluids. The clean room  100  can also have output lines  120  that allow for the removal of used processing fluids from the semiconductor processing unit  118 . Some of the input lines  114  can provide computer-networking capacity allowing the semiconductor processing unit  118  to be monitored and controlled from a remote location. Other input lines  114  may supply processing fluid to a storage tank within the ancillary chamber  116 . The output lines  120  can facilitate the removal of used processing fluid from a storage tank within the ancillary chamber  116 .  
         [0026]      FIG. 2  is a simplified diagram of a cross section of semiconductor process  102  within the chamber body  104  in accordance with one embodiment of the present invention. In one embodiment, the wafer  106  is passing through a meniscus of a process fluid  202  maintained between heads  204 . The heads  204  can be used to plate a metallic layer, such as copper or other metals, or the heads  204  can be used to apply and remove fluids to define controlled fluid menisci (shown as fluid  202 ). In another embodiment the process fluid  202  is sprayed directly onto the wafer  106 . To ensure the process fluid  202  covers the maximum area of the wafer  106  the process fluid  202  is allowed to contact the wafer carrier  108 . As the process fluid  202  flows onto and around the wafer carrier  108  it is possible that some of the process fluid  202  can drip or flow off the wafer carrier  108  and onto the chamber body  104 .  
         [0027]      FIG. 3  is a simplified diagram of a cross section of a spin drying semiconductor process  102  within the chamber body  104  in accordance with one embodiment of the present invention. In this embodiment the wafer  106  is secured to a device  110  that can rotate at a high enough speed so fluid is removed from the surface of the wafer  102  by centrifugal force. Various process fluids  202  can be introduced to the surface of the wafer  106  and subsequently the wafer is spun dry. Spin drying the wafer allows the process fluids  202  to contact the chamber body  104  and can allow pools  304  of the process fluids  202  to form on the interior surface  302  of the chamber body  104 . These pools  304  can then flow out through appropriate exit holes or channels.  
         [0028]     Process fluids  202  that can be used within the chamber body  104  found in  FIG. 2  and  FIG. 3  include highly reactive chemicals such as hydrofluoric acid, ozonated water, deionized water or mixtures with chemicals, isopropyl alcohol, ammonia, etc. The chemicals listed are exemplary and are not intended to limit the type of chemicals that can be used within the chamber body  104 . Because a chamber body can be exposed to highly reactive chemicals and the semiconductor processes conducted in the chamber bodies are sensitive to contamination, a chamber body must be substantially chemically inert.  
         [0029]      FIG. 4  is a diagram of a cross-section of a substantially chemically inert chamber body  104  showing different layers of material used to coat the chamber body  104  in accordance with one embodiment of the present invention. The base material  406  is the chamber body, and in one embodiment the base material  406  can be an aluminum alloy. In another embodiment the base material  406  can be a ferrous alloy. In yet another embodiment the base material  406  can be a titanium alloy. In another embodiment the base material  406  can be a composite material such as carbon fiber. In another embodiment the base material  406  can be a ceramic.  
         [0030]     The primer coat  404  is applied over the base material  406 . The primer coat  404  can contain metallic as well as non-metallic components and can be applied using a variety of techniques. In one embodiment the primer coat  404  can be a powder coating that is electrostatically sprayed onto the base material  406 . In another embodiment the primer coat  404  can be painted on the base material  406 . In yet another embodiment the base material can be dipped into a vat filled with the primer coat  404  material. After the application of the primer coat  404  the base material with the primer coat can be cured using any variety of techniques capable of varying temperature, pressure, and humidity. The application of multiple layers of primer coat  404  may be necessary to create a layer of sufficient thickness to protect the base material  406  and provide a stable bonding surface for the main coat  402 . In one embodiment, the primer coat  404  is Composition  1  applied and cured as multiple layers of an electrostatic powder coating to a thickness of between about 0.005 inches and about 0.025 inches over a base material  406  of an aluminum alloy.  
         [0031]     In one embodiment, Composition  1  can be a coating material obtained from Solvay Solexis, S.p.A. of Bollate, Italy, and Composition  1  can be Halar 9414. Halar 9414 was selected, as its performance in application to the chamber body was found to be of high quality. The constituents of particular usefulness include about 0.5% titanium, about 2.4% aluminum, about 1.3% silicon, about 40% carbon, about 0.6% chlorine, about 32% oxygen and about 23% fluorine. Note that Halar 9414 is only one example, and Composition  1  can be either mixed from base elements or obtained from other suppliers that can approximate the mixture of the constituents. In particular, it is believed that the constituents of Composition  1 , find particular usefulness in defining good adhesion and integration with the metallic structure of the chamber body. As will be discussed below, Composition  1  was also selected so as to define a base for the following main coat  402 .  
         [0032]     The main coat  402  is therefore applied over the primer coat  404 . In order to minimize the possibility of creating metallic contamination from a reaction between the main coat  402  and any chemicals used within the chamber body  104  the composition of the main coat  402  should minimize metallic content. The techniques used to apply and cure the main coat can be the same as those used to apply the primer coat  404 . As with the primer coat  404 , multiple applications of the main coat  402  may be required to achieve the desired thickness. In one embodiment the main coat  402  is Composition  2  applied and cured in multiple layers of an electrostatic powder coating to a thickness of 0.010-0.090 inches over the primer coat  404  of Composition  1 . In one embodiment, Composition  2  can be coating material obtained from Solvay Solexis, S.p.A. of Bollate, Italy, and Composition  2  can be Halar 6014F. Halar 6014F was selected, as its performance in application to the chamber body was found to be of high quality. The constituents of particular usefulness include about 65% carbon, about 4.4% chlorine, and about 30% fluorine. It is noted that Halar 6014F is only one example, and Composition  2  can be either mixed from base elements or obtained from other suppliers that can approximate the mixture of the constituents. In particular, it is believed that the constituents of Composition  2 , find particular usefulness in not producing detrimental contamination when exposed to the process chemicals  202 . As will be discussed below, Composition  2  was also selected because of its clear color and machinable qualities when fully cured.  
         [0033]     One of the many advantages of using the combination of Composition  1  as the primer coat  404  and Composition  2  as the main coat  402  is that the final color of the chamber body  104  conforms to industry tradition. Traditionally, chamber bodies have been constructed from plastics such as PVC or PTFE that have a whitish or yellowish color. When fully cured the primer coat  404  of Composition  1  is a whitish color while the main coat  402  of cured Composition  2  is substantially clear. Therefore, application of Composition  1  over Composition  2  to a chamber body results in a chamber body with a whitish color. Because users of semiconductor processing equipment have become accustomed to the whitish or yellowish color of chamber bodies the use of Composition  1  and Composition  2  provides users with a familiar color.  
         [0034]     The precision and accuracy required to maximize output from modern semiconductor processing equipment requires exacting tolerances. Multiple reference data surfaces that are part of a chamber body  104  can minimize process variations by locating process equipment in definite areas. The over application of the primer coat  404  and the main coat  402  can require the removal of excess material from a reference data surface. One of the many advantages of using Composition  2  as the main coat  402  is ability to machine Composition  2  after the final coating is cured without adversely affecting chemical resistance of the Composition  2 . Thus, if a reference data surface has an excessive amount of main coating a mill or other type of process can be used to remove the excess material and bring the reference data surface back within specified tolerances.  
         [0035]      FIG. 5  is a flow chart illustrating the procedure of creating a chamber body in accordance with one embodiment of the present invention. The process starts with operation  500  and is followed by operation  502  where the chamber body is created from a base material. A chamber body created from a metal alloy can be formed using machining and joint processes such as milling, drilling, welding and bonding. A ceramic chamber body can be created using sintering, injection molding or another ceramic forming process. The formation of the chamber body is not limited to the types of materials and processes listed above.  
         [0036]     After the chamber body is formed, execution of operation  504  coats the chamber body. As discussed above, coating the chamber body can be done with a primer coat and a main coat. Multiple applications of coatings may be required to achieve the desired thickness of the respective coatings. Additionally, it is possible that one or both of the primer coat and main coat may be composed of non-homogenous layers of various coatings.  
         [0037]     Upon completion of operation  504 , operation  506  processes the coated chamber body. Processing the chamber body is intended to identify uneven application of the coatings to the chamber body. Processing the chamber body can also include removing uneven applications of the coating that are found to compromise the dimensional tolerances of the chamber body. Once the chamber body has been processed, the procedure is completed with operation  508 .  
         [0038]      FIG. 6  is a flow chart illustrating the procedure to coat the chamber body in accordance with one embodiment of the present invention. The process starts with operation  600  and proceeds to operation  602  where the exterior surface of the base material is subjected to an abrading process such as grit blasting or sanding. The abrading process may facilitate the adhesion of the coatings to a metallic surface by roughening the surface and providing more adhesion surface area for the coating. In one embodiment the material used to abrade the chamber body is aluminum oxide. If the chamber body is composed of a ceramic or composite material abrading the chamber body may not be necessary depending on the surface finish of the chamber body. After being abraded, operation  604  applies a layer of primer coat. The process continues with operation  606  where the primer coat is cured to a dimensionally stable hardness and operation  608  where the chamber body is allowed to cool. One skilled in the art should recognize that operation  608  might not be necessary if operation  606  is conducted at room temperature. Operation  610  is used to check if the primer coat has reached the desired thickness. If the primer coat has not reached the desired thickness the procedure returns to execute operation  604  through operation  610 . Note that before additional layers of the primer coat are added, the chamber body may be abraded to improve adhesion of a next layer of primer coat. Once the primer coat has reached the desired thickness, the procedure advances to operation  612 .  
         [0039]     Operation  612  applies a layer of the main coat followed by operation  614  that cures the main coat to a dimensionally stable hardness. Operation  616  allows the chamber body to cool after going through the curing operation. Note that operation  616  may not be necessary depending on the conditions required to cure the main coat. Operation  618  checks if the main coat is at the desired thickness. If the chamber body requires additional main coating the procedure execute operation  612  through  618 . Similar to the primer coat, before additional lawyers of the main coat are added, the chamber body may be abraded to improve adhesion of a next layer of main coat. Once the main coat has reached the desired thickness, the procedure is completed at operation  620 .  
         [0040]      FIG. 7  is a flow chart illustrating the procedure to process a chamber body in accordance with one embodiment of the present invention. The operation begins with operation  702  and advances to operation  704  where measurements are taken of the final dimensions of the chamber body. The measurements can include layer thicknesses in specific areas acquired using ultrasonic measuring techniques and other critical dimension acquired using a variety of measuring techniques. Execution of operation  706  verifies that the dimensions acquired in operation  704  are with specified dimensions and tolerances. If the chamber body dimensions are not within the specified tolerances operation  708  advances the procedure to operation  710  where main coating is removed in areas in excess of the specified tolerance. If the chamber body dimensions are within the specified tolerances, operation  708  advances the procedure to operation  712  where the chamber body is cleaned. The procedure is completed with operation  714 .  
         [0041]      FIG. 8A  is a schematic illustrating a chamber body  104  in accordance with one embodiment of the present invention. The chamber body  104  has a bottom surface  800  that is integrally connected with wall surfaces  802  that form an interior cavity. In one embodiment, the chamber has an overall width  810  of about 21 inches and an overall length  812  of about 60 inches. Note that the dimensions provided for the chamber body  104  are not intended to be limiting. In one embodiment the chamber body  104  can be fabricated by machining the chamber from a single billet of material. In another embodiment, modular chamber body component pieces can be assembled to form the chamber body  104 .  
         [0042]     As shown in  FIG. 8A , there can be a variety of opening to the interior cavity of the chamber body  104  along with a variety of reference data surfaces. For example, ports  804  and  808  provide access to the interior cavity of the chamber body  104  via circular openings. Note that ports  804  are located on bosses  814  that include reference data surfaces  816 . The reference data surfaces  816  can be used to locate and position semiconductor processing equipment within the chamber body  104 . Port  806  and port  806 ′ provide access to the interior cavity of the chamber body  104  using rectangular opening. In one embodiment of the invention, a substrate enters the chamber body  104  by passing through port  806 . The substrate can be processed by equipment at least partially within the chamber body  104  and passed out of the chamber body  104  through port  806 ′ when processing within the chamber body  104  is completed. The location and dimensions of port  806  and  806 ′ can also be considered reference data surfaces. Note that ports  808 , shown in a recessed area of the interior cavity of the chamber body  104  can also be considered reference data surfaces.  
         [0043]      FIG. 8B  is a schematic illustrating a proximity head and substrate carrier  852  installed in a chamber body  104  in accordance with one embodiment of the present invention. The substrate carrier  852  is shown without a substrate in places permitting viewing of a bottom head  850 ′ of the proximity head. A top head  850  of the proximity head is located substantially above, and spaced away from the bottom head  850 ′, to allow the substrate carrier  852  to pass between the top head  850  and bottom head  850 ′. Ports  806  and  806 ′ allows substrates to be moved in and out of the chamber body.  
         [0044]      FIG. 9  is a schematic illustrating a semiconductor processing unit  118  with a chamber body  104 , in accordance with one embodiment of the present invention. The semiconductor processing unit  118  can include environmental controls  902 . The environmental controls  902  can include, but are not limited to, air filtration systems and temperature and humidity control. Input lines  114  can supply power and processing fluids while output lines can facilitate the removal of processing fluids from the semiconductor processing unit  118 . Electronics backbone  904  associated with the semiconductor processing unit  118  can interface with a computer  906  and/or a computer network. The electronics backbone  904  enables control and monitoring of processes within the semiconductor processing unit  118  through the computer  906  or remotely via the computer network.  
         [0045]     A frame  900  is located within an enclosure  908 . The chamber body  104  can be coupled to the frame  900 . In one embodiment, semiconductor processing equipment is attached to the frame  900  and the chamber body  104 . In other embodiments, semiconductor processing equipment is attached to only the chamber body  104 . Wafer carriers  108  and  108 ′ are one of the many types of semiconductor processing equipment that can be associated with the chamber body  104 . The wafer carrier  108  can assist in moving a substrate into the chamber body via port  806 . Similarly, wafer carrier  108 ′ can be used to move a substrate out of the chamber body via port  806 ′. A proximity head  110  for performing wet substrate processing can be associated with the chamber body  104 . The proximity head  110  can perform a variety of wet processes including cleaning and plating of a substrate. Other embodiment can include multiple proximity heads or additional semiconductor processing equipment associated with the chamber body  104 . The particular types of semiconductor processing equipment discussed are not intended to be limiting.  
         [0046]     In one embodiment, fluids are supplied to the semiconductor processing equipment from vessels  910 . The vessels  910  can be used to store and/or mix process fluids supplied from input lines  114 . In one embodiment, supply lines  912  and  912 ′ can pass through ports in the chamber body  104  to transport process fluids from the vessels  910  to the proximity head  110 . Additionally, drain line  914  can be connected to a port on the chamber body  104  to provide recovery of overflow fluid from the proximity head  110 . In other embodiments, the proximity head  110  can be configured to recover and recycle process fluids that may require recycling lines to return process fluids to the vessels  910 . In yet other embodiments utilizing more than one proximity head or additional semiconductor processing equipment, individual drains can be formed in the chamber body  104  to enable recycling of different process fluids.  
         [0047]      FIGS. 10A and 10B  are different views of modular chamber body components  1002 ,  1003  and  1004  in accordance with one embodiment of the present invention. To provide flexibility to when processing substrates and simplify fabrication, assembly and installing of the chamber body, it may be advantageous to associate modular chamber body components with a particular piece of semiconductor processing equipment. As shown in  FIG. 10A , chamber body component  1002  can be used as the left most component of the chamber body  104  while chamber body component  1006  can be used as the right most component. In each case, chamber body components  1002  and  1006  can be configured to accommodate a wafer carrier  108 . Chamber body component  1004  can be configured to accommodate a variety of semiconductor processing equipment by including mounting surfaces that can be designed to meet a standard for ease of alignment, setup, installation, and sourcing.  
         [0048]     In the embodiment illustrated in  FIGS. 10A and 10B , a proximity head is shown associated with the chamber body component  1004 . In order to accommodate the proximity head, or other semiconductor processing equipment, the chamber body component  1004  can allow for removable assemblies and piece parts. As the embodiments illustrated are intended to be exemplary and not intended to be restrictive, other embodiments of chamber body components can be configured with different removable assemblies and piece parts for different semiconductor processing equipment. Note that configuring the chamber body components for different semiconductor processing equipment can include adding or removing ports to accommodate input and output lines.  
         [0049]     In one embodiment, chamber body components are formed and exposed to primer coat material and main coat material before being assembled into a completed chamber body. In another embodiment, chamber body components are formed and assembled into a completed chamber body before the application of primer coat and main coat materials. In yet other embodiments, as previously discussed, the chamber body is not formed from modular chamber body components, but rather from a single piece of base material.  
         [0050]      FIGS. 11A-11D  are various cross-sectional views of an interface between chamber body components in accordance with embodiments of the present invention. As illustrated in  FIG. 11A , chamber body component  1002  includes a tenon  1102  that can interface with a mortise  1104  of chamber body component  1004 . In one embodiment, mortise  1104  and tenon  1102  features can be spaced at regular or irregular intervals along the interface between chamber body components  1002  and  1004 . In another embodiment the mortise  1104  and tenon  1102  can extend along the interface between chamber body components  1002  and  1004 .  
         [0051]     The embodiment shown in  FIG. 11B  includes interlocking surfaces  1108  and  1110  and a fluid barrier  1106 . As each chamber body component can be associated with a particular piece of semiconductor processing equipment, the use of fluid barriers  1106  can assist in recovering and recycling process fluids by preventing process fluids from mixing. For example, chamber body component  1004  could be located beneath a proximity head performing a plating operation while chamber body component  1105  could be located beneath a proximity head performing a cleaning operation. Fluid barriers  1106  can help prevent fluid from the plating operation from mixing with fluid from the cleaning operation and assist in recovery and recycling of the respective fluids. The embodiment illustrated in  FIG. 11C  uses a different style mortise  1104  and tenon  1102  in conjunction with a fluid barrier  1106 . The embodiment illustrated in  FIG. 11D  shows forming the bottom of the chamber body components to promote draining of any recovered process fluid. The embodiments shown in  FIG. 11A-11D  are intended to be illustrative and not intended to be limiting. As previously discussed, chamber body components can include multiple ports for supply and drain lines. Furthermore, a chamber body can be composed of any number of chamber body components and associated semiconductor processing equipment.
