Vacuum pump protection against deposition byproduct buildup
A processing chamber such as a plasma etch chamber can perform deposition and etch operations, where byproducts of the deposition and etch operations can build up in a vacuum pump system fluidly coupled to the processing chamber. A vacuum pump system may have multiple roughing pumps so that etch gases can be diverted a roughing pump and deposition precursors can be diverted to another roughing pump. A divert line may route unused deposition precursors through a separate roughing pump. Deposition byproducts can be prevented from forming by incorporating one or more gas ejectors or venturi pumps at an outlet of a primary pump in a vacuum pump system. Cleaning operations, such as waferless automated cleaning operations, using certain clean chemistries may remove deposition byproducts before or after etch operations.
Plasma Processing Apparatus and Plasma Processing Method
A plasma processing, apparatus of an embodiment includes a chamber, an introducing part, a first power source, a holder, an electrode, and a second power source. The introducing pat introduces gas into the chamber. The first power source outputs a first voltage for generating ions from the gas. The holder holds a substrate. The electrode is opposite to the ions across the substrate, and has a surface not parallel to the substrate. The second power source applies a second voltage to the electrode. The second voltage has a frequency lower than the frequency of the first voltage and Introduces die ions to the substrate.
