Abstract:
1. A method of decreasing the frequency of chamber cleaning processes for a process chamber of a processing system, the method comprising: introducing one or more first substrates into the process chamber; performing a first manufacturing process on the one or more first substrates in the process chamber whereby a first film deposit is formed on a chamber component in the process chamber; removing the one or more first substrates from the process chamber; exposing the chamber component in the process chamber to a reactant gas to form a particle-reducing film, wherein the particle-reducing film is: introducing one or more second substrates into the process chamber; performing a second manufacturing process on the one or more second substrates in the process chamber whereby a new film deposit is formed on the particle-reducing film, and wherein the particle-reducing film reduces particle formation in the process chamber during processing of the one or more second substrates from one or both of the first film deposit or the new film deposit; and removing the one or more second substrates from the process chamber.
