Claim 6:
7. A method of depositing a SiO or SiN film, the method comprising:
exposing a substrate to a silicon precursor in a first process region of a processing chamber;
laterally moving the substrate through a gas curtain to a second process region of the processing chamber;
exposing the substrate to a first plasma in the second process region of the processing chamber, the first plasma generated by a first plasma port directly coupled to a first match circuit, the first plasma having a first phase;
laterally moving the substrate through a gas curtain to a third process region of the processing chamber;
exposing the substrate to a silicon precursor in the third process region;
laterally moving the substrate through a gas curtain to a fourth process region of the processing chamber;
exposing the substrate to a second plasma in the fourth process region of the processing chamber, the second plasma generated by a second plasma port directly coupled to a second match circuit, the second plasma having a second phase; and
controlling of the first phase or the second phase to maintain a phase difference in a range of about 170° to about 190°.
