[0015] Various embodiments of the present invention relate to apparatus and devices for an electrostatic chuck. The electrostatic chuck may have a body constructed of one or more layers. Each layer may contain one or more components. In some embodiments, the electrostatic chuck includes at least one layer comprising (but not limited to) a dielectric layer, an electrode layer, a bonding layer, an adhesive layer, an electrode circuit layer, an insulating layer, a heating circuit layer, an electrical isolation layer, or any combination thereof. In some embodiments, the electrostatic chuck may include a plurality of layers. In some embodiments, the electrostatic chuck may include at least one component comprising (but not limited to) an electrode contact pin, a heating contact pin, an electrical conductor, a heating element, a sensor, other components, or any combination thereof. In some embodiments, at least one layer of the electrostatic chuck may contain an organic material, such as (e.g., but not limited to) a polymeric material. In some embodiments, at least one layer containing an organic material may be a thermoplastic made of a polymeric material. The electrostatic chuck may include an encapsulating coating that acts as a vapor deposition layer, as will be further described herein.

[0016] The polymeric material may contain (but is not limited to) at least one of the following: acrylate polymers, polyolefins, polyamides, polyethers, polycarbonates, polyurethanes, vinyl polymers, fluoropolymers, other types of polymers, or any combination thereof. In some embodiments, the polymeric material may contain (but is not limited to) at least one of the following: fluorinated ethylene propylene (FEP), fluoropolymers, high-density polyethylene (HDPE), low-density polyethylene (LDPE), medium-density polyethylene (MDPE), perfluoroalkoxyalkylene (PFA), polybutene (PB), poly(butyl acrylate) (PBA), poly(ethyl acrylate) (PEA), polyacrylonitrile (PAN), polyaryletherketone (PAEK), polybutadiene, polybutylene adipate (PBAT), polybutylene succinate (PBS), polybutylene terephthalate (PBT), polychlorotrifluoroethylene (PCTFE or PTFCE), polyethers Imine, polyethylene (PE), polyetheretherketone (PEEK), polyetherketoneketone (PEKK), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyglycolic acid (PGA), polystyrene (PPSU), polymethylpentene (PMP), polypropylene (PP), nylon, polyoxobutane (POX), polyoxymethylene (POM), polyphenylene ether (PPE), polypropylene glycol (PPG), polystyrene (PS), polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), polyvinyl fluoride (PVF), polyvinylcarbazole (PVK), polyvinylidene chloride (PVDC), polyvinylidene fluoride (PVDF), or any combination thereof.

[0017] An electrostatic chuck may comprise a plurality of layers. At least one layer of the electrostatic chuck may comprise an organic material. The at least one layer comprising an organic material may be disposed within a respective layer of the electrostatic chuck such that at least a portion of the layer comprising the organic material is exposed to, or, if uncovered, exposed to, the external environment. That is, the at least one layer comprising an organic material may be disposed adjacent to another layer of the electrostatic chuck or may be disposed between two or more other layers of the electrostatic chuck such that at least a portion of the surface of the at least one layer comprising the organic material not covered by another layer of the electrostatic chuck is exposed to the external environment. For example, the layer comprising the organic material may be an electrically insulating layer positioned adjacent to a ceramic insulating layer, and one or more sides of the layer comprising the organic material not covered by the ceramic insulating layer may be exposed to the external environment. In another example, the layer comprising the organic material may be a bonding layer located between a dielectric layer and an insulating layer, and at least one sidewall of the layer comprising the organic material may be exposed to the external environment. It should be understood that, without departing from the scope of the invention, the at least one layer comprising the organic material may comprise one or more other functional components.

[0018] Electrostatic chucks can be used in various types of environments. Therefore, electrostatic chucks can be exposed to different environmental conditions. When an electrostatic chuck is used in or exposed to oxidizing atmospheres (such as ozone treatment or H2 plasma exposure), the organic material forming at least one layer of the electrostatic chuck can age or otherwise be damaged, which can lead to premature failure of the electrostatic chuck. The surface of an electrostatic chuck formed of or including organic material may be located in areas of the electrostatic chuck that are difficult to access (such as structures with a high aspect ratio). For example, at least one layer containing organic material may be sandwiched between two other layers or components. In this regard, at least one layer containing organic material may, for example, expose one side of at least one layer not covered by adjacent components or layers to harmful species (such as ozone or H2). Harmful species can thereby cause damage to the organic material of at least one layer of the electrostatic chuck at portions between adjacent components, which can lead to premature wear, aging, and failure of the electrostatic chuck.

[0019] An electrostatic chuck includes an encapsulating coating formed by vapor deposition. The encapsulating coating protects the surface of at least one layer of an electrostatic chuck containing or formed of organic materials from potential aging or damage, particularly from exposure to hazardous materials such as (e.g., but not limited to) ozone, H2 plasma, etc. When applied to one or more portions of the electrostatic chuck, the encapsulating coating forms a highly conformal coating or portion of the coating to seal or encapsulate organic materials or similar easily aging materials, thereby extending the durability and / or lifespan of the electrostatic chuck. An encapsulating coating is provided to cover at least a portion of at least one component of an electrostatic chuck containing organic materials. Once a vapor-deposited layer is formed on one or more portions of the surface of the electrostatic chuck using the encapsulating coating, the encapsulating coating encapsulates at least a portion of at least one layer forming the surface of the electrostatic chuck and protects it from exposure to hazardous species in a hazardous environment. That is, the encapsulation coating forms a vapor deposition layer to cover at least one or more portions of the surface of an electrostatic chuck containing at least one component, the at least one component comprising an organic material and not covered by another component or layer of the electrostatic chuck.

[0020] In some embodiments, at least one of the layers of the electrostatic chuck may comprise an organic material, and an encapsulating coating may be applied to the electrostatic chuck to form a vapor-deposited layer covering at least a portion of the electrostatic chuck. In some embodiments, the vapor-deposited layer encapsulates at least a portion of the surface of the electrostatic chuck comprising at least one layer, the at least one layer comprising an organic material originally exposed to the external environment. In other embodiments, two or more layers of the electrostatic chuck may comprise an organic material, and a vapor-deposited layer may be applied as one or more portions to the electrostatic chuck to cover portions of two or more layers forming a surface of the electrostatic chuck, the vapor-deposited layer encapsulating at least a portion of the surface of the electrostatic chuck formed by the respective layers, the respective layers comprising an organic material originally exposed to the external environment. In other embodiments, an encapsulating coating may be applied to an electrostatic chuck to form a vapor-deposited layer that substantially covers one of the outer surfaces of the electrostatic chuck, thereby encapsulating the surface of the electrostatic chuck (including (but not limited to) at least one of the following: a layer containing organic material, other layers, a surface-extending component of one of the layers, or any combination thereof), thereby protecting the electrostatic chuck or one or more portions thereof from harmful materials in a harmful environment to which the electrostatic chuck would otherwise be exposed in the external environment.

[0021] In some embodiments, an encapsulating coating covers a surface of an electrostatic chuck comprising an organic material, or at least a portion thereof. In some embodiments, the encapsulating coating may cover a high aspect ratio structure having a surface comprising an organic material. Non-limiting examples of a high aspect ratio structure include (e.g., but not limited to) at least one of the following: a structure defining an air chamber, a structure defining a trench, a structure defining a well, a structure defining a pore, a structure defining an opening, a structure defining a channel, a structure defining a cavity (e.g., defining a partially enclosed region of a cavity), a flat surface, a non-flat surface, or any combination thereof. As used herein, the term "high aspect ratio" refers to a structure having a ratio of two dimensions, wherein the width across the structure is much larger than the height of the structure. Thus, an electrostatic chuck has a high aspect ratio when the width across each layer of an electrostatic chuck is much larger than the height defined by the plurality of layers. Non-limiting examples of dimensions include (for example, but not limited to) at least one of the following: a length, a width, a height, a depth, a diameter, a circumference, or any combination thereof.

[0022] In some embodiments, the surface containing organic material is located in a structure having an aspect ratio of any range or subrange between 2:1 and 1000:1 or the like. For example, the surface containing organic material is located in a structure having one of the following aspect ratios: at least 2:1, at least 3:1, at least 4:1, at least 5:1, at least 6:1, at least 7:1, at least 8:1, at least 9:1, at least 10:1, at least 15:1, at least 20:1, at least 25:1, at least 30:1, at least 35:1, at least 40:1, at least 45:1, at least 50:1, at least 55:1, at least 60:1, at least 65:1, at least 70:1, at least 75:1, at least 80:1, at least 85:1, at least 90:1, at least 95:1, at least 100:1, at least 200:1, at least 300:1, at least 400:1, at least 500:1, at least 600:1, at least 700:1, at least 800:1, at least 900:1 to 1000:1 and / or any range or subrange between these.

[0023] An encapsulating coating forming a vapor deposition layer can be formed on an electrostatic chuck using a vapor deposition process to create a highly conformal coating or coating portion at the electrostatic chuck, sealing or encapsulating at least one layer of organic material or similar easily aging material, thereby extending the durability and / or lifespan of the electrostatic chuck. The encapsulating coating can be a uniform, dense layer encapsulating one or more portions of the surface of the electrostatic chuck, configured to have virtually no defects varying according to the deposition process. The encapsulating coating can be formed on the unprotected surface of the electrostatic chuck conformally to the surface of the underlying component. The encapsulating coating can have a substantially uniform thickness across one of the coated portions of the electrostatic chuck. In some embodiments, the encapsulating coating can have a substantially equal thickness across one of the coated portions, varying according to the deposition process. It should be understood that the encapsulating coating is not intended to be limited to forming on a flat surface, but can be formed on any surface having a plurality of different geometries, including those capable of coating complex geometries with high aspect ratios. For example, vapor-deposited layers can be suitable for coating geometries with high aspect ratios, including (but not limited to) small-diameter holes, deep recesses, spaces, gaps, and other geometries that can form the surface of components containing organic materials or can be located between components.

[0024] An encapsulating coating can cover all or at least a portion of a surface of an electrostatic chuck containing an organic material that may be exposed to the external environment of the chuck. In some embodiments, the electrostatic chuck includes a first layer, a second layer, a third layer, and an encapsulating coating, a second layer located between the first and third layers and containing an organic material, and the encapsulating coating forming a vapor-deposited layer covering at least a portion of the electrostatic chuck such that the encapsulating coating completely covers the second layer not covered by the first and third layers. In some embodiments, the encapsulating coating forming the vapor-deposited layer completely covers an outer surface of the electrostatic chuck. For example, in some embodiments, the encapsulating coating forming the vapor-deposited layer covers at least one of: a top surface of the electrostatic chuck, a bottom surface of the electrostatic chuck, a side surface of the electrostatic chuck, one or more portions thereof, or any combination thereof. In some embodiments, the vapor-deposited layer covers any range or subrange between 1% and 99% of an outer surface of the electrostatic chuck. In some embodiments, the vapor-deposited layer covers 1% to 90%, 1% to 80%, 1% to 70%, 1% to 60%, 1% to 50%, 1% to 40%, 1% to 30%, 1% to 20%, 1% to 10%, 10% to 99%, 20% to 99%, 30% to 99%, 40% to 99%, 50% to 99%, 60% to 99%, 70% to 99%, 80% to 99%, or 90% to 99%. In some embodiments, the encapsulating coating forming the vapor-deposited layer is in direct contact with the surface containing the organic material.

[0025] The encapsulation coating that forms the vapor-deposited layer may have a thickness of any range or subrange between 10 nm and 300 nm or the like. In some embodiments, the vapor-deposited layer may have one of the following thicknesses: 10 nm to 300 nm, 20 nm to 300 nm, 30 nm to 300 nm, 40 nm to 300 nm, 50 nm to 300 nm, 75 nm to 300 nm, 100 nm to 300 nm, 150 nm to 300 nm, 200 nm to 300 nm, 250 nm to 300 nm, 10 nm to 250 nm, 20 nm to 250 nm, 30 nm to 250 nm, 40 nm to 250 nm, 50 nm to 250 nm, 75 nm to 250 nm, 100 nm to 250 nm, 150 nm to 250 nm, 200 nm to 250 nm, 10 nm to 200 nm, 20 nm to 200 nm, 30 nm to 200 nm, 40 nm to 200 nm, 50 nm to 200 nm, 75 nm to 200 nm. nm, 100 nm to 200 nm, 150 nm to 200 nm, 10 nm to 150 nm, 20 nm to 150 nm, 30 nm to 150 nm, 40 nm to 150 nm, 50 nm to 150 nm, 75 nm to 150 nm, 100 nm to 150 nm, 10 nm to 100 nm, 20 nm to 100 nm, 30 nm to 100 nm, 40 nm to 100 nm, 50 nm to 100 nm, 75 nm to 100 nm, 10 nm to 75 nm, 20 nm to 75 nm, 30 nm to 75 nm, 40 nm to 75 nm, 50 nm to 75 nm, 10 nm to 50 nm, 20 nm to 50 nm, 30 nm to 50 nm, or 40 nm to 50 nm. In some embodiments, the vapor-deposited layer has a thickness of one of 10 nm to 300 nm. In some embodiments, the vapor-deposited layer has a thickness of 10 nm to 200 nm. In some embodiments, the vapor-deposited layer has a thickness of 10 nm to 250 nm. In some embodiments, the vapor-deposited layer has a thickness of 30 nm to 100 nm.

[0026] In some embodiments, the encapsulating coating forming the vapor-deposited layer is capable of withstanding thickness variations in response to exposure of the electrostatic chuck to a material harmful to the electrostatic chuck's organic or other materials. In some embodiments, when the encapsulating coating is exposed to a harmful material comprising, for example, ozone, plasma, or any combination thereof, at a temperature of 10°C to 130°C for a duration of 6 hours to 24 hours, the thickness variation of the electrostatic chuck before and after exposure is 10% or less, 9% or less, 8% or less, 7% or less, 6% or less, 5% or less, 4% or less, 3% or less, 2% or less, or 1% or less. In some embodiments, when the electrostatic chuck is exposed to at least one of ozone, plasma, or any combination thereof at a temperature of 10°C to 130°C for a duration of 6 hours to 24 hours, the thickness change of the electrostatic chuck before and after exposure is 0.01% to 10%, 0.01% to 9%, 0.01% to 8%, 0.01% to 7%, 0.01% to 6%, 0.01% to 5%, 0.01% to 4%, 0.01% to 3%, 0.01% to 2%, 0.01% to 1%, 0.1% to 10%, 1% to 10%, 2% to 10%, 3% to 10%, 4% to 10%, 5% to 10%, 6% to 10%, 7% to 10%, 8% to 10%, or 9% to 10%. For example, when an electrostatic chuck is exposed to at least one of ozone atmosphere, plasma, or other harmful materials that can damage organic materials at a temperature of 100°C for a duration of 6 to 20 hours, the thickness variation of the encapsulation coating is 1% or less.

[0027] In some embodiments, when the electrostatic chuck is exposed to at least one of ozone, plasma, or any combination thereof at a temperature of 10°C to 130°C for a duration of 6 hours to 24 hours, the change in the metallic composition of the encapsulation coating before and after exposure is 10% or less, 9% or less, 8% or less, 7% or less, 6% or less, 5% or less, 4% or less, 3% or less, 2% or less, or 1% or less, as measured by energy-dispersive X-ray spectroscopy. In some embodiments, when the electrostatic chuck is exposed to at least one of ozone, plasma, or any combination thereof at a temperature of 10°C to 130°C for a duration of 6 hours to 24 hours, the change in the metallic composition of the vapor-deposited layer before and after exposure is 0.01% to 10%, 0.01% to 9%, 0.01% to 8%, 0.01% to 7%, 0.01% to 6%, 0.01% to 5%, 0.01% to 4%, 0.01% to 3%, 0.01% to 2%, 0.01% to 1%, 0.1% to 10%, 1% to 10%, 2% to 10%, 3% to 10%, 4% to 10%, 5% to 10%, 6% to 10%, 7% to 10%, 8% to 10%, or 9% to 10%, as measured by energy-dispersive X-ray spectroscopy. For example, when an electrostatic chuck is exposed to at least one of ozone atmosphere, plasma, or other harmful materials that can damage organic materials at a temperature of 100°C for a duration of 6 to 20 hours, the change in the metallic composition of the encapsulation coating is less than 5%.

[0028] It should be understood that the number of layers forming the electrostatic chuck is not intended to be limited and may include one, two, three, four, five, six, or more than six layers, with at least one of the layers containing one or more components according to the invention. It should also be understood that although the electrostatic chuck is described herein as comprising one or more layers and one or more components, this is not intended to be limiting.

The film is sequentially deposited onto the substrate using an ALD process until the encapsulation coating 120 is formed as a film encapsulating at least a portion 124 of a second layer 112 between the first layer 110 and the third layer 116. In some embodiments, the encapsulation coating 120 film may encapsulate one or more layers of the electrostatic chuck, such as (for example) one or more portions of the first layer 110, the second layer 112, the third layer 116, or any combination thereof.

In some embodiments, the encapsulating coating 120 covers 1% to 99% of the outer surface of the electrostatic chuck 102. In other embodiments, the encapsulating coating 120 may cover the entire outer surface of the electrostatic chuck 102 except for the electrodes extending from the bottom 106 surface of the electrostatic chuck 102. That is, the encapsulation coating 120 can almost cover the entire outer surface of the electrostatic chuck 102, which includes needles, such as at least one electrode needle 134 (see FIG. 2) or at least one heating element needle 152 (see FIG. 5) extending through one or more layers and the encapsulation coating 120 and protruding from the bottom 106 of the electrostatic chuck 102.

[0065] The electrostatic chuck 102 may further include an electrode layer 132 comprising at least one electrode located between the first layer 110 and the second layer 112. The electrode layer 132 includes a patterned metal coating formed by the at least one electrode.
