Systems and methods for fabricating semiconductor device structures using different metrology tools

摘要

Methods and systems are provided for fabricating and measuring physical features of a semiconductor device structure. An exemplary method of fabricating a semiconductor device structure involves obtaining a first measurement of a first attribute of the semiconductor device structure from a first metrology tool, obtaining process information pertaining to fabrication of one or more features of the semiconductor device structure by a first processing tool, and determining an adjusted measurement for the first attribute based at least in part on the first measurement in a manner that is influenced by the process information.
