Claim One:
1. A method of film deposition in a sub-atmospheric chemical vapor deposition (CVD) process, comprising: a) providing a model for sub-atmospheric CVD deposition of a film that identifies one or more film properties of the film and at least one deposition model variable that correlates with the one or more film properties; b) depositing a film onto a wafer using a first deposition recipe comprising at least one deposition recipe parameter that corresponds to the at least one deposition variable; c) measuring a film property of at least one of said one or more film properties for the deposited film of step (b); d) calculating an updated deposition model based upon the measured film property of step (c) and the model of step (a); and e) calculating an updated deposition recipe based upon the updated model of step (d) to maintain a target film property.
