Computer-implemented inter-chamber synchronization in a multiple chamber substrate processing system

摘要

A computer-implemented method of achieving inter-chamber synchronization in a system for integrated circuit manufacturing that includes first and second chambers. In particular, the disclosed method includes terminating a second operation in a second recipe carried out in the second chamber, upon termination of a first operation in a first recipe carried out in the first chamber. Performance advantages realized by the method are illustrated for various cases including 1) a variable-length first operation; 2) a fixed-length first operation; 3) a process first recipe; 4) a conditioning first recipe; 5) a process second recipe; and 6) a conditioning second recipe.
