Claim 4:
5. The method according to claim 1, wherein, after exposing the substrate to the gaseous metal-containing precursor, further comprising the steps of:
(a) exposing the substrate to the process gas at a first pressure at or below 0.8 Torr while applying a voltage of at least 700 Volts and frequency less than 500 kHz to the electrode to form on the substrate a first film having a first type of stress;
(b) after step (a), again exposing the substrate to the metal-containing precursor;
(c) during a period of time between and including steps (a) and (d), modulating the pressure of the process gas between the first pressure and a second pressure also at or below 0.8 Torr but different from the first pressure; and
(d) after step (b), exposing the substrate to the process gas at the second pressure while applying a voltage of at least 700 Volts and frequency less than 500 kHz to the electrode to form over the first film a second film having a second type of stress that is different from the first type of stress.
