Classification: CPC H  C | IPC C  H

Claim 16:
17. A method comprising:
exposing a substrate surface to a first process condition in a first process region of a processing chamber, the first process condition comprising a constant flow of a first reactive gas comprising WF6 and a pulsed flow of a second reactive gas consisting essentially of H2, the second reactive gas pulsed so that there is less than a full amount of the second reactive gas for CVD;
purging the substrate surface of the first processing condition to remove the WF6 and the H2;
exposing the substrate surface to a second process condition in the second process region, the second process condition consisting essentially of the H2;
purging the substrate surface of the second processing condition; and
repeating exposure to the first process condition, purge of the substrate surface, and exposure to the second process condition to deposit a film of a predetermined thickness.
