We have discovered that controlling a combination of PECVD deposition process parameters during deposition of silicon-containing thin film provides improved control over surface standing wave effects. By minimizing surface standing wave effects, the uniformity of film properties (particularly film thickness) across a substrate surface onto which the films have been deposited is improved.
