Patent ID: 7767584

Claim:
A method for semiconductor process chamber operation, comprising: depositing a silicon containing layer over an inner surface of an empty semiconductor process chamber, the depositing including creating a plasma while flowing a silicon containing gas consisting of essentially silicon and one of bromine or chlorine into the semiconductor process chamber; introducing a wafer into the semiconductor process chamber after depositing the silicon containing layer; performing a process operation on the wafer, the process operation depositing a residue on the silicon containing layer covering the inner surface of the semiconductor process chamber; removing the wafer from the semiconductor process chamber; and initiating an in-situ cleaning process upon completion of the processing operation and removal of the wafer, the initiating including: flowing a fluorine containing gas into the semiconductor process chamber; and establishing a pressure within the semiconductor process chamber capable of allowing a plasma created from the fluorine containing gas to clear the silicon containing layer covering the inner surface of the processing chamber.
