Classification: H01L

Abstract:
A computer program product including a computer usable medium having computer readable program code embodied therein for a kill index classification method for prioritizing relational aspects of topological defect intersections in a semiconductor fabrication process, the computer readable program code in said computer usable medium including at least one program code selected from:a) first computer readable program code for causing a computer to locate a region having at least one non-predetermined portion therein; b) tied to the first computer readable program code, second computer readable program code for causing the computer to determine a predetermined topology for the region; c) tied to the second computer readable program code, third computer readable program code for causing the computer to calculate evaluation parameters based on the at least one non-predetermined portion in relation to the predetermined topology for the region; and d) tied to the third computer readable program code, fourth computer readable program code for causing the computer to assign a kill index classification using the calculated evaluation parameters; wherein the kill index classification method includes the steps ofa) locating a region having at least one non-predetermined portion therein; b) determining a predetermined topology for the region; c) calculating evaluation parameters based on the at least one non-predetermined portion in relation to the predetermined topology for the region; and d) assigning a kill index classification using the calculated evaluation parameters.
