Patent ID: 7201936

Claim:
A method of film deposition in a run-to-run chemical vapor deposition (CVD) process, comprising: a) providing a model for CVD deposition of a film, wherein the model is responsive to a tool state of the CVD process and 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 first substrate 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), wherein said updated model is calculated after each run of the run-to-run process; and e) calculating an updated deposition recipe for use in a film deposition onto a second substrate based upon the updated model of step (d) to maintain a target film property.
