摘要:
A method and apparatus for processing a substrate utilizing a rotating substrate support are disclosed herein. In one embodiment, an apparatus for processing a substrate includes a chamber having a substrate support assembly disposed within the chamber. The substrate support assembly includes a substrate support having a support surface and a heater disposed beneath the support surface. A shaft is coupled to the substrate support and a motor is coupled to the shaft through a rotor to provide rotary movement to the substrate support. A seal block is disposed around the rotor and forms a seal therewith. The seal block has at least one seal and at least one channel disposed along the interface between the seal block and the shaft. A port is coupled to each channel for connecting to a pump. A lift mechanism is coupled to the shaft for raising and lowering the substrate support.

Provided herein is an emissivity-change-free pumping plate kit used in a single wafer chamber. This kit comprises a top open pumping plate, and optionally a skirt and/or a second stage choking plate. The skirt may be installed around the wafer heater, underneath the wafer heater, or along the chamber body inside the chamber. The choking plate is installed downstream of the top open pumping plate along the purge gas flow. Also provided is a method of preventing emissivity change and further providing optimal film thickness uniformity during wafer processing by utilizing such kit in the chamber.
