A containment vessel for evaporating materials for use in applying film coatings to a substrate includes a body fabricated from a refractory material. In one embodiment the body includes end portions capable of being connected to other bodies in an end to end fashion. In another embodiment, the body includes an integral patterned conductor incorporated into the outer surface portion of the body to facilitate association with an electrical power source for heating.

Large volume evaporation source

A wafer processing device or apparatus, i.e., a heater or an electrostatic chuck, comprises a planar support platen, a support shaft having centrally located bore, and a pair of electrical conductors located in the shaft. In one embodiment, the electrical conductors are concentrically located within the bore of the shaft, with the first electrical lead being in the form of a pyrolytic graphite rod and separated from the outer second graphite electrical lead by means of a pyrolytic boron nitride (pBN) coating. In a second embodiment, the support platen and the support shaft are formed from a single unitary body of graphite. In yet another embodiment of the device of the invention, the connection posts comprise a carbon fiber composite and the exposed ends of the electrical connectors are coated with a protective ceramic paste for extended life in operations.

Wafer handling apparatus and method of manufacturing thereof

A graphite heater and method of forming a graphite heater comprising a graphite body configured to form an electrical heating circuit for at least one heating zone through the graphite encapsulated in a continuous overcoat layer comprising at least one of a nitride, carbide, carbonitride or oxynitride of elements selected from a group consisting of B, Al, Si, Ga, refractory hard metals, transition metals, and rare earth metals, or complexes and/or combinations thereof, wherein prior to being configured to form the electrical heating circuit path, the graphite body is coated with a layer comprising at least one of a nitride, carbide, carbonitride or oxynitride of elements selected from a group consisting of B, Al, Si, Ga, refractory hard metals, transition metals, and rare earth metals, or complexes and/or combinations thereof.
