Patent ID: 7329586

Claim:
A method of depositing a film on a substrate disposed in a substrate processing chamber, the substrate having a gap formed between adjacent raised surfaces, the method comprising: providing flows of first precursor deposition gases to the substrate processing chamber; forming a first high-density plasma from the flows of first precursor deposition gases to deposit a first portion of the film over the substrate and within the gap with a first deposition process that has simultaneous deposition and sputtering components until after the gap has closed; etching back a sufficient part of the first portion of the film to reopen the gap; providing flows of second precursor deposition gases to the substrate processing chamber; and forming a second high-density plasma from the flows of second precursor deposition gases to deposit a second portion of the film over the substrate and within the reopened gap with a second deposition process that has simultaneous deposition and sputtering components.
