Patent ID: 8298626

Claim:
A method for processing a substrate in a plasma processing system, the method comprising: disposing a first confinement ring set in a first position such that it circumscribes a first area; depositing a first coating on a first portion of the plasma processing system using a first plasma in the first area defined by the first confinement ring set in the first position; disposing a second confinement ring set in a position such that the first confinement ring set is interposed between the first area and the second confinement ring set when said first confinement ring set is in the first position and disposing the second confinement ring such that it circumscribes the first confinement ring set in the first position; depositing a second coating on a second portion of the plasma processing system using a second plasma in a second area between the first confinement ring set in the first position and the second confinement ring set; processing the substrate using a third plasma with the first confinement ring set disposed in a second position; and wherein, the first coating is formed using the first plasma formed using an ignited silicon-containing material ignited in the first area; and wherein, the second coating is formed using the second plasma formed using an ignited hydrocarbon-containing material ignited in the second area.
