    摘要: A substrate support includes a disc body with an upper surface and an opposite lower surface arranged along a rotation axis. The upper surface has a circular concave portion extending about the rotation axis, an annular ledge portion extending circumferentially about the concave portion, and an annular rim portion extending circumferentially about the ledge portion connecting to the concave portion of the disc body by the ledge portion of the disc body. The ledge portion slopes downward radially outward from the rotation axis to seat a substrate on the disc body such that a beveled edge of the substrate is cantilevered above the ledge portion of the upper surface of the disc body. Substrate support assemblies, semiconductor processing systems, and film deposition methods are also described.

    摘要: Systems of reducing devitrification within a chemical vapor deposition system can include a susceptor support ring that is configured to be positioned between a gas inlet and a gas outlet of a chamber passage. An example system can also include a getter support comprising a support base and one or more recesses therein. Each of the one or more recesses can be arranged to receive corresponding one or more support elements that are configured to support the getter plate. At least a portion of the getter support may include a coating comprising silicon carbide (SiC) having a thickness of at least about 50 microns. The getter support may be arranged to be disposed a maximum distance of between about 1 mm and about 10 mm from the susceptor support ring.

    摘要: A semiconductor processing system includes a gas delivery module, and a chamber body connected to the gas delivery module. The divider has an aperture, is fixed within an interior of the chamber body, and separates an interior of the chamber body into upper and lower chambers, the aperture fluidly coupling the lower chamber to the upper chamber. A susceptor is arranged within the aperture. A controller is operably connected to the gas delivery module to purge the lower chamber with a first purge flow including an etchant while etching the upper chamber, purge the lower chamber with a second purge flow including the etchant while depositing a precoat in the upper chamber, and purge the lower chamber with a third purge flow including the etchant while depositing a film onto a substrate in the upper chamber. Film deposition methods and lower chamber etchant purge kits are also described.

    摘要: A substrate support and lift assembly configured to support and lift a substrate from a susceptor is disclosed. The substrate support and lift assembly can include a susceptor support and a lift pin. The susceptor support can be configured to support the susceptor thereon. The susceptor support includes a plurality of support arms each extending radially from a central portion of the susceptor support to a terminus. Each of the plurality of support arms includes an aperture extending therethrough. The lift pin can be configured to fit through the aperture of a corresponding support arm to lift a substrate on the susceptor.
