Abstract:
Embodiments of the invention include a deposition machine that allows for continuous deposition of an object or substrate with a coating having a graded composition. The deposition machine includes a deposition chamber separated into a plurality of chamber areas by a baffle having an opening. The opening allows for migration of deposition material from one chamber area to another, allowing for a graded composition coating to be deposited on the object or substrate. Other embodiments include a system for forming an electronic device and a system and method for forming a graded composition on an object.
Abstract:
A wafer processing device for use in semiconductor wafer processing applications as an electrostatic chuck comprises a graphite substrate (1) and at least one electrode pattern (3) , wherein the grooves in the electrode pattern are filled up with insulating material (2) comprising at least one of a nitride, carbide, carbonitride or oxynitride, or combination thereof , of at least one element selected from a group consisting of B, Al, Si, Ga, refractory hard metals, transition metals, and rare earth metals, a combination thereof, forming a first substantially planar surface. This first substantially planar surface is coated with at least a semiconducting layer (4) comprising at least one of a nitride, carbide, carbonitride or oxynitride or combination thereof of at least one element selected from a group consisting of B, A, Si, Ga, refractory hard metals, transition metals, and rare earth metals, or a combination thereof, forming a second substantially planar surface, which is outwardly exposed to support said wafer.
Abstract:
A composite article comprises a substrate (340) having at least a substrate surface and a graded-composition coating (350) disposed on a substrate surface. The composition of the coating material varies substantially continuously across its thickness. The coating (350) reduces the transmission rates of oxygen, water vapor, and other chemical species through the substrate (340) such that the composite article can be used effectively as a diffusion barrier to protect chemically sensitive devices (320) or materials. An organic light-emitting device (310) incorporates such a composite article to provide an extended life thereto.
Abstract:
Disclosed is a composite article and methods for making a composite article where the composite article includes a coating material formed from an organic material having a first refractive index and an inorganic material having a second refractive index where the refractive indexes match. The methods may include depositing the coating using a plasma-enhanced chemical-vapor deposition technique. The methods may further include varying the deposition rate of one or both of the organic and inorganic material so as to match the refractive indexes.
Abstract:
A composite article (30) with at least one high integrity protective coating, the high integrity protective coating having at least one planarizing layer and at least one organic-inorganic composition barrier coating layer (10) . A method for depositing a high integrity protective coating.
Abstract:
Embodiments for an apparatus and method for depositing one or more layers onto a substrate or a freestanding shape inside a reaction chamber operating at a temperature of at least 7000C and 100 torr are provided. The apparatus is provided with means for defining a volume space in the reaction chamber for pre-reacting the reactant feeds forming at least a reaction precursor in a gaseous form, separated from a deposition zone for depositing a coating layer of uniform thickness on the substrate from the reacted precursor. In one embodiment, the means for defining the two different zones comprises a distribution medium. In another embodiment, the means comprises a plurality of reactant feed jets or injectors. In another embodiment, the apparatus is provided with a feeding system having injection means spatially spaced apart for tailoring the distribution of a plurality of gas-phase species, yielding a deposit that is substantially uniform in thickness and chemical composition along the substrate surface. In one embodiment, the apparatus further comprises a sacrificial substrate that further helps achieving thickness and chemical uniformity on the substrate.
Abstract:
An electro-optical device (100) having at least one base (110) and a multilayer coating surface disposed on at least one surface of the base (110). The at least one base (110) may comprise either an optically or electronically active portion (140) or a flexible polymeric material. The multilayer coating set (120) comprises at least one organic layer (124) and at least one inorganic layer (122). The base (110) and multilayer coating set (120) are transparent. The multilayer coating set 120 provides a barrier to moisture and oxygen and provides chemical resistance. The multilayer coating set (120) is also mechanically flexible and thermally stable up to a glass transition temperature of the base (110).
