Abstract:
A method of adjusting the density of plasma contained in a chamber wherein substrates are to be processed comprising:a) providing a chamber containing a plasma processing gas for processing at least one substrate and said chamber including a chamber wall having a dielectric member releasably engaged thereto;b) introducing processing power through said dielectric member and into an interior of said chamber to process at least one substrate in said plasma processing gas having a first plasma density;c) interrupting the introducing of said processing power through said dielectric member and into said interior of said chamber;d) disengaging said dielectric member from said chamber wall;e) securing to a certain situs on an inside surface of said dielectric member, a material deposition support assembly for receiving and supporting a deposition of materials during processing of at least one substrate in said chamber;f) reengaging said dielectric member with said chamber wall; andg) reintroducing processing power through said dielectric member and into said chamber to process at least one substrate in the plasma processing gas having an adjusted, second plasma density.
