Patent ID: 7390757

Claim:
A method of depositing a film on a substrate having a gap between adjacent raised surfaces, said method comprising: (a) positioning a substrate in a deposition chamber, wherein said substrate comprises at least one gap formed between adjacent raised surfaces; (b) providing a gas mixture to the deposition chamber, wherein the gas mixture comprises a fluorinated silicon source, a fluorine source different from said fluorinated silicon source, a hydrogen source, and a oxidizer; and (c) reacting the gas mixture in the presence of an electric field to generate a plasma having an ion density of at least 10 11 ions/cm 3 to thereby deposit a fluorine-containing silicon oxide film within said gap using a process having simultaneous deposition and sputtering components; wherein said gas mixture does not comprise a silane compound having the general formula Si X H Y , wherein x has a range of 1 to 2, y has a range of 4 to 6.
