Referring toFIGS.2to3, a thickness TT of the first insulating layer400on the other surface102of the body100may be greater than a thickness TE of the first insulating layer400on each of the both end surfaces105and106of the body100. In this case, the thickness TT of the first insulating layer400on entire regions of the other surface102of the body100may be greater than the thickness TE of the first insulating layer400on entire regions of each of the both end surfaces105and106of the body100. The thickness TT of the first insulating layer400on the other surface102of the body100may not be constant, and, as will be described later, the thickness TE of the first insulating layer400on the both end surfaces105and106of the body100may not be constant. In this case, the thicknesses TT and TE of the first insulating layer400may refer to an average thickness of the first insulating layer400.

The thickness TE of the first insulating layer400on each of the both end surfaces105and106of the body100may be about 0.5 to about 1 of the thickness TT of the first insulating layer400on the other surface102of the body100, but the present disclosure is not limited thereto.

In some embodiments, the thickness TE of the first insulating layer400on each of the both end surfaces105and106of the body100may decrease in a direction from the other surface102of the body100to the one surface101of the body100. The thickness TE of the first insulating layer400on each of the both end surfaces105and106of the body100may gradually decrease in a direction from the other surface102of the body100to the one surface101of the body100, and may decrease to include one or more regions having a step difference in a region between the other surface102of the body100and the one surface101of the body100. In some embodiments, the first insulating layer400on each of the both end surfaces105and106of the body100may also include a region in which the thickness TE increases in a direction from the other surface102of the body100to the one surface101of the body100.

Referring toFIG.3, the first insulating layer400on each of the both end surfaces105and106of the body100may include a first region400E1, a second region400E2, and a third region400E3, sequentially disposed in a direction from the other surface102of the body100to the one surface101of the body100. The first region400E1, the second region400E2, and the third region400E3may refer to terms for distinguishing regions adjacent to each other of the first insulating layer400integrally formed on each of the both end surfaces105and106of the body100, and a boundary indicated by a dotted line on the drawings may be a virtual line for convenience of explanation. The first region400E1, the second region400E2, and the third region400E3may have the same length or different lengths in a direction from the other surface102of the body100to the one surface101of the body100.

An average thickness TE1of the first insulating layer400in the first region400E1may be greater than an average thickness TE2of the first insulating layer400in the second region400E2, and the average thickness TE2of the first insulating layer400in the second region400E2may be greater than an average thickness TE3of the first insulating layer400in the third region400E3. A coil component according to an embodiment of the present disclosure may have such a structure by decreasing the thickness TE of the first insulating layer400on each of the both end surfaces105and106of the body100in a direction from the other surface102of the body100to the one surface101of the body100, as described above.

In this case, the thickness TT of the first insulating layer400on entire regions of the other surface102of the body100may be greater than the thickness TS of the first insulating layer400on entire regions of each of the both lateral surfaces103and104of the body100. The thickness TT of the first insulating layer400on the other surface102of the body100may not be constant, and as will be described later, the thickness TS of the insulating layer400on each of the both lateral surfaces103and104of the body100may not be constant. In this case, the thicknesses TT and TS of the first insulating layer400may refer to an average thickness of the first insulating layer400.

The thickness TS of the first insulating layer400on each of the both lateral surfaces103and104of the body100may be about 0.5 to about 1 of the thickness TT of the first insulating layer400on the other surface102of the body100, but the present disclosure is not limited thereto. The thickness TS of the first insulating layer400on each of the both lateral surfaces103and104of the body100may be the same as or different from the thickness TE of the first insulating layer400on each of the both end surfaces105and106of the body100.

In some embodiments, the thickness TS of the first insulating layer400on each of the both lateral surfaces103and104of the body100may decrease in a direction from the other surface102of the body100to the one surface101of the body100. The thickness TS of the first insulating layer400on each of the both lateral surfaces103and104of the body100may gradually decrease in a direction from the other surface102of the body100to the one surface101of the body100, and may decrease to include one or more regions having a step difference in a region between the other surface102of the body100and the one surface101of the body100. In some embodiments, the first insulating layer400on each of the both lateral surfaces103and104of the body100may also include a region in which the thickness TS increases in a direction from the other surface102of the body100to the one surface101of the body100.

Referring toFIG.5, the first insulating layer400on each of the both lateral surfaces103and104of the body100may include a first region400S1, a second region400S2, and a third region400S3, sequentially disposed in a direction from the other surface102of the body100to the one surface101of the body100. The first region400S1, the second region400S2, and the third region400S3may refer to terms for distinguishing regions adjacent to each other of the first insulating layer400integrally formed on each of the both lateral surfaces103and104of the body100, and a boundary indicated by a dotted line on the drawings may be a virtual line for convenience of explanation. The first region400S1, the second region400S2, and the third region400S3may have the same length or different lengths in a direction from the other surface102of the body100to the one surface101of the body100.

An average thickness TS1of the first insulating layer400in the first region400S1may be greater than an average thickness TS2of the first insulating layer400in the second region400S2, and the average thickness TS2of the first insulating layer400in the second region400S2may be greater than an average thickness TS3of the first insulating layer400in the third region400S3. A coil component1000according to an embodiment of the present disclosure may have such a structure by decreasing the thickness TS of the first insulating layer400on each of the both lateral surfaces103and104of the body100in a direction from the other surface102of the body100to the one surface101of the body100, as described above. A method of measurement of the thickness of the first insulating layer includes, but not limited to, a method using an optical microscope. Specifically, it can be used as a measurement sample by polishing from the surface103or104to the surface passing through the center of the coil component so as to be parallel to103and104of the body100. Next, the first insulating layer400can be observed using an optical microscope, and the cross section of the first insulating layer400is divided into three regions (400S1,400S2,400S3), and three points of each region by calculating the arithmetic mean value of the thickness measured in, the thickness of each region (TS1, TS3, TS3) can be obtained.

In a coil component1000according to an example, the first insulating layer400may be prepared by forming an insulating material on the other surface102, the both lateral surfaces103and104, and the both end surfaces105and106of the body100by a chemical vapor deposition (CVD) process. In this case, since a gas may flow in a direction from the other surface102of the body100to the one surface101of the body100, thicknesses of the first insulating layer400on the other surface102, the both lateral surfaces103and104, and the both end surfaces105and106of the body100may be formed to be different from each other, as described above.

The present inventors have confirmed that when a first insulating layer400is formed as described above, a thin insulating layer in which the first insulating layer400has a thin thickness of 5 μm or less at any points may be formed. Therefore, a coil component is capable of increasing an effective volume of a magnetic material based on the same volume may be provided.

Hereinafter, a configuration of a coil component1000according to an embodiment of the present disclosure will be described in more detail.

The body100may form an exterior of a coil component1000according to this embodiment, and the coil unit200may be embedded therein.

The one surface101and the other surface102of the body100may oppose each other in a first direction 1, the both lateral surfaces103and104of the body100may oppose each other in a second direction 2, perpendicular to the first direction 1, and the both end surfaces105and106of the body100may oppose each other in a third direction 3, perpendicular to each of the first and second directions 1 and 2. The body100may be formed in a hexahedral shape overall, but is not limited thereto.

The body100may include a magnetic material and a resin. Specifically, the body100may be formed by stacking one or more magnetic composite sheets including a magnetic material dispersed in a resin. The magnetic material may be a ferrite powder or a metal magnetic powder.

Examples of the ferrite powder may include at least one or more of spinel type ferrites such as Mg—Zn-based ferrite, Mn—Zn-based ferrite, Mn—Mg-based ferrite, Cu—Zn-based ferrite, Mg—Mn—Sr-based ferrite, Ni—Zn-based ferrite, and the like, hexagonal ferrites such as Ba—Zn-based ferrite, Ba—Mg-based ferrite, Ba—Ni-based ferrite, Ba—Co-based ferrite, Ba—Ni—Co-based ferrite, and the like, garnet type ferrites such as Y-based ferrite, and the like, and Li-based ferrites.

The metal magnetic powder may include any one or more selected from the group consisting of iron (Fe), silicon (Si), chromium (Cr), cobalt (Co), molybdenum (Mo), aluminum (Al), niobium (Nb), copper (Cu), nickel (Ni), and alloys thereof. For example, the metal magnetic powder may include at least one or more of a pure iron powder, a Fe—Si-based alloy powder, a Fe—Si—Al-based alloy powder, a Fe—Ni-based alloy powder, a Fe—Ni—Mo-based alloy powder, a Fe—Cr-based alloy powder, or a Fe—Cr—Si-based alloy powder.

The metallic magnetic powder may be amorphous or crystalline form. For example, the metal magnetic powder may be a Fe—Si—B—Cr-based amorphous alloy powder, but is not limited thereto.

The resin may include one or more an epoxy resin, a polyimide, a liquid crystal polymer, or the like, but is not limited thereto.

The body100may include a core110passing through the coil unit200to be described later. The core110may be formed by filling a through-hole of the coil unit200with a magnetic composite sheet, but is not limited thereto.

The slit S may be formed in an edge portion between each of the both end surfaces105and106of the body100and the one surface101of the body100. In this case, the edge portion may refer to a region adjacent to an intersection between a virtual surface extending each of the both end surfaces105and106of the body100in the first direction 1 and a virtual surface extending the one surface101of the body100in the third direction 3.

The slit S may be formed by removing a partial region of the body100in the first direction 1 from the one surface101of the body100to the other surface102of the body100. The slit S may not entirely pass through the body100in the first direction 1 from the one surface101of the body100to the other surface102of the body100. Specifically, in a coil bar, which is a state before individualizing a plurality of coil components, the slit S may be formed by performing pre-dicing on one surface101of the coil bar on a boundary disposed between both end surfaces105and106of each of the plurality of coil components, among boundaries for individualizing the coil components. In such pre-dicing, a depth of the slit S may be adjusted to expose lead-out portions231and232, described later, through the slit S as illustrated inFIG.2.

The slit S may extend to the both lateral surfaces103and104of the body100in the second direction 2. Therefore, the slit S may pass through entirely the body100in the second direction 2, in the edge portion between each of the both end surfaces105and106of the body100and the one surface101of the body100.

An inner wall surface and a bottom surface of the slit S may also constitute a surface of the body100. In this specification, for convenience of description, the inner wall surface and the bottom surface of the slit S are distinguished from the surfaces101,102,103,104,105, and106of the body100.

The coil unit200may be embedded in the body100to express characteristics of a coil component. For example, when the coil component1000of this embodiment is used as a power inductor, the coil unit200may serve to stabilize power of an electronic device by storing an electric field as a magnetic field and maintaining an output voltage.

The coil unit200may include a support substrate210, first and second coil patterns221and222, first and second lead-out portions231and232, first and second auxiliary lead-out portions241and242, and vias251,252, and253. For example, as illustrated inFIGS.2and4, a first coil pattern221and lead-out portions231and232may be disposed on a lower surface of the support substrate210, a second coil pattern222and auxiliary lead-out portions241and242may be disposed on an upper surface of the support substrate210, and first, second and third vias251,252, and253may be formed to pass through the support substrate210.

The first coil pattern221may be in contact with and connected to the first lead-out portion231, and the first coil pattern221and the first lead-out portion231may be spaced apart from the second lead-out portion232. The second coil pattern222may be in contact with and connected to the second auxiliary lead-out portion242, and the second coil pattern222and the second auxiliary lead-out portion242may be spaced apart from the first auxiliary lead-out portion241. A first via251may connect the first lead-out portion231and the first auxiliary lead-out portion241to each other, a second via252may connect the second lead-out portion232and the second auxiliary lead-out portion242to each other, and the third via253may connect the first coil pattern221and the second coil pattern222to each other. Therefore, the coil unit200may entirely function as a single coil.

Each of the first coil pattern221and the second coil pattern222may have a planar, spiral shape in which at least one turn is formed around the core110.

Each of the first lead-out portion231and the second lead-out portion232, which may be a portion of the coil unit200, may be exposed through the slit S. For example, the slit S may be formed by removing a portion of the body100in the first direction 1 by the pre-dicing process described above, and further removing a portion of each of the first lead-out portion231and the second lead-out portion232. Therefore, each of the first lead-out portion231and the second lead-out portion232may be exposed through the slit S. Therefore, the first lead-out portion231and the second lead-out portion232may be disposed on the inner wall surface and the bottom surface of the slit S. In addition, the first external electrode310and the second external electrode320may be respectively provided on the first lead-out portion231and the second lead-out portion232, disposed on the inner wall surface and the bottom surface of the slit S.

The first lead-out portion231and the second lead-out portion232may be exposed from the both end surfaces105and106of the body100, respectively, and the first auxiliary lead-out portion241and the second auxiliary lead-out portion242may be also exposed from the both end surfaces105and106of the body100, respectively.

A material for forming each of the first and second coil patterns221and222, the first and second lead-out portions231and232, the first and second auxiliary lead-out portions241and242, and the first, second and third vias251,252, and253may comprises a conductive material such as copper (Cu), aluminum (Al), silver (Ag), tin (Sn), gold (Au), nickel (Ni), lead (Pb), titanium (Ti), or alloys thereof.

The first and second coil patterns221and222, the first and second lead-out portions231and232, the first and second auxiliary lead-out portions241and242, and the first, second and third vias251,252, and253may include at least one conductive layer. For example, the first and second coil patterns221and222, the first and second lead-out portions231and232, the first and second auxiliary lead-out portions241and242, and the first, second and third vias251,252, and253may be formed by a plating process, and may include an electroless plating layer and an electrolytic plating layer disposed on the electroless plating layer, which may function as a seed layer.

Each of the first external electrode310and the second external electrode320may be at least partially disposed in the slit S. In addition, each of the first external electrode310and the second external electrode320may extend onto the one surface101of the body100, and may be arranged to be spaced apart from each other. Specifically, each of the first external electrode310and the second external electrode320may form the inner wall surface and the bottom surface of the slit S, may extend onto the one surface101of the body100, and may be arranged to be spaced apart from each other. In this case, each of the first external electrode310and the second external electrode320may be arranged to form the one surface101of the body100, and spaced apart from each other in the third direction 3. Each of the first external electrode310and the second external electrode320may be connected to each of the first lead-out portion231and the second lead-out portion232, exposed through the slit S, to implement a lower electrode structure.

The first insulating layer400may cover the other surface102of the body100, the both lateral surfaces103and104of the body100, and the both end surfaces105and106of the body100, to play a role of insulating these surfaces. As necessary, the first insulating layer400may partially cover only some surface, among the other surface102of the body100, the both lateral surfaces103and104of the body100, and the both end surfaces105and106of the body100. For example, the first insulating layer400may cover the other surface102of the body100and the both end surfaces105and106of the body100, and may not cover the both lateral surfaces103and104of the body100.

The first insulating layer400may be prepared by forming an insulating material on the other surface102, the both lateral surfaces103and104, and the both end surfaces105and106of the body100by a chemical vapor deposition (CVD) process, as described above. The first insulating layer400may be formed of an insulating material including at least one of polyacrylate or parylene, and thus, the first insulating layer400may include at least one of polyacrylate or parylene. I some embodiments, Polyacylate may include polyacrylate derivatives, and parylene may include parylene N, parylene C, parylene D, and other parylene derivatives.

A thickness of the first insulating layer400may be 10 μm or less, and preferably 5 μm or less at any points. Therefore, a coil component is capable of increasing an effective volume of a magnetic material based on the same volume may be provided.

The first insulating layer400may not be formed in the slit S. Therefore, a length of the first insulating layer400on the both lateral surfaces103and104of the body100in the first direction 1 may be different from a length of the first insulating layer400on the both end surfaces105and106of the body100in the first direction 1. Specifically, a length of the first insulating layer400on the both lateral surfaces103and104of the body100, in which the slit S is not formed, in the first direction 1 may be greater than a length of the first insulating layer400on the both end surfaces105and106of the body100, in which the slit S is formed, in the first direction 1.

The second insulating layer500may cover a region of the first external electrode310and a region of the second external electrode320, disposed in the slit S, to secure insulation of a remaining region, except for the one surface101of the body100. The second insulating layer500may also extend onto the both end surfaces105and106of the body100, to further cover at least a portion of the first insulating layer400. In this case, on the both end surfaces105and106of the body100, the first insulating layer400may be entirely covered by the second insulating layer500, or only a portion of the first insulating layer400may be covered by the second insulating layer500.

As a material for forming the second insulating layer500, an insulating material may be used without limitation. For example, a thermoplastic resin such as polyimide, a thermosetting resin such as an epoxy resin, a photosensitive resin, or the like may be used.

A method of forming the second insulating layer500is not particularly limited, but may be formed by a process of printing an insulating material or applying a liquid insulating material. Alternatively, the second insulating layer500may also be formed by laminating an insulating film.

The third insulating layer600may prevent a short circuit between the first external electrode310and the second external electrode320on the one surface101of the body100. As a material for forming the third insulating layer600, a material having insulating properties may be used without limitation. For example, a thermoplastic resin such as polyimide, a thermosetting resin such as an epoxy resin, a photosensitive resin, or the like may be used.

A method of forming the third insulating layer600is also not particularly limited, but may be formed by a process of printing an insulating material or applying a liquid insulating material. Alternatively, the third insulating layer600may also be formed by laminating an insulating film.

Referring toFIG.6, in a coil component according to a modified example of the embodiment of the present disclosure, a second insulating layer500covers only a portion of a first insulating layer400on both end surfaces105and106of a body100.

In addition, remaining descriptions may be applied in a manner substantially identical to the descriptions of the coil component according to the embodiments of the present disclosure, detailed descriptions thereof will be omitted.

Referring to the drawings, in a coil component1000′ according to another embodiment of the present disclosure, no slit may be formed in a body100.

In addition, a coil unit200may include a support substrate210, first and second coil patterns221and222, first and second lead-out portions231and232, and a via253, and may not include an auxiliary lead-out portion. For example, as illustrated inFIGS.8and10, the first coil pattern221and the second lead-out part232may be disposed on a lower surface of the support substrate210, the second coil pattern222and the first lead-out portion231may be disposed on an upper surface of the support substrate210, and the via253may be formed to pass through the support substrate210.

As illustrated inFIG.8, a first external electrode310and a second external electrode320may cover both end surfaces105and106of the body100, and may extend onto one surface101of the body100, and are spaced apart from each other. Each of the first external electrode310and the second external electrode320may have an ‘L’ shape, but are not limited thereto. For example, the first external electrode310and the second external electrode320may have a ‘C’ shape.

As illustrated inFIG.7, since a coil component1000′ according to another embodiment does not have a slit formed in the body100, a first insulating layer400may entirely cover a region of each of the both end surfaces105and106. In this case, no insulating layer500may be required.

In addition, remaining descriptions may be applied in a manner substantially identical to the descriptions of the coil component according to the embodiments of the present disclosure, detailed descriptions thereof will be omitted.

A coil component according to another embodiment of the present disclosure is provided to explain that a coil component of the present disclosure may have various structures, and a structure of a coil component according to the present disclosure should not be limited to the embodiments.

As used herein, the term “connect” or “connection” in the present specification may not be only a direct connection, but also a concept including an indirect connection. In addition, the term “electrically connected” or “electrical connection” in the present specification is a concept including both a physical connection and a physical non-connection.

The expression “example” used in this specification does not refer to the same embodiment to each other, but may be provided for emphasizing and explaining different unique features. The above-mentioned examples do not exclude that the above-mentioned examples are implemented in combination with the features of other examples. For example, although the description in a specific example is not described in another example, it may be understood as an explanation related to another example, unless otherwise described or contradicted by the other example.

In the present specification, the expressions of “first,” second,” etc. in the present specification are used to distinguish one component from another, and do not limit the order and/or importance of the components. In some cases, without departing from the spirit of the present disclosure, a “first” component may be referred to as a “second” component, and similarly, a “second” component may be referred to as a “first” component.

The terms used in the present disclosure are used only to illustrate various examples and are not intended to limit the present inventive concept. Singular expressions include plural expressions unless the context clearly dictates otherwise.

As one of various effects of the present disclosure, a coil component including a thin insulating layer having a relatively thin thickness may be provided.

As another effect of the various effects of the present disclosure, a coil component is capable of increasing an effective volume of a magnetic material may be provided.
