Abstract:
Disclosed are methods of depositing films of material on multiple semiconductor substrates in a multi-station processing chamber. The methods may include loading a first set of one or more substrates into the processing chamber at a first set of one or more process stations and depositing film material onto the first set of substrates by performing N cycles of film deposition. Thereafter, the methods may further include transferring the first set of substrates from the first set of process stations to a second set of one or more process stations, loading a second set of one or more substrates at the first set of process stations, and depositing film material onto the first and second sets of substrates by performing N′ cycles of film deposition, wherein N′ is not equal to N. Also disclosed are apparatuses and computer-readable media which may be used to perform similar operations.
