    摘要: The present invention provides a process kit for a semiconductor processing chamber. The processing chamber is a vacuum processing chamber that includes a chamber body defining an interior processing region. The processing region receives a substrate for processing, and also supports equipment pieces of the process kit. The process kit includes a pumping liner configured to be placed within the processing region of the processing chamber, and a C-channel liner configured to be placed along an outer diameter of the pumping liner. The pumping liner and the C-channel liner have novel interlocking features designed to inhibit parasitic pumping of processing or cleaning gases from the processing region. The invention further provides a semiconductor processing chamber having an improved process kit, such as the kit described. In one arrangement, the chamber is a tandem processing chamber.
