Abstract
A method of depositing a film that includes heterogeneously seasoning a processing chamber is provided. After a processing chamber is cleaned, a heterogeneous seasoning deposition is performed to stabilize the deposition rate drift before a substrate may be positioned therein. A film, such as a SiOfilm, may then be deposited on the substrate. The substrate may then be removed from the processing chamber and replaced with a second substrate. A film may then be deposited on the second substrate. The substrate positioning, deposition, and substrate removal cycle may be repeated until the cleaning cycle is complete. The processing chamber may be cleaned a second time, and another series of substrates may be similarly processed.
