Patent ID: 7188049

Claim:
A control system for a plurality of manufacturing processes, comprising: an inspection tool configured to inspect a dislocation image of a dislocation generated in a semiconductor substrate processed by a plurality of manufacturing processes; an inspection information input module configured to acquire the inspected dislocation image; a process condition input module configured to acquire a plurality of process conditions of the manufacturing processes; a structure information input module configured to acquire a structure of the semiconductor substrate processed by a target manufacturing process; a stress analysis module configured to calculate stresses at a plurality of nodes provided in the structure, based on a target process condition of the target manufacturing process and the structure; an origin setting module configured to provide a plurality of origins at positions where a stress concentration having a stress value not less than a reference value is predicted; a dislocation dynamics analysis module configured to calculate a dislocation pattern of an analysis dislocation line in a stress field by the stresses for each position of the origins; and a dislocation pattern comparison module configured to compare the dislocation pattern of the analysis dislocation line with the inspected dislocation image so as to determine whether the target manufacturing process is a critical manufacturing process that generates the dislocation.
