Abstract
A method for statistically analyzing structural test information to identify at least one yield loss mechanism includes executing a plurality of instructions on a computer system. The executed instructions cause the computer system to perform the steps of: 1) identifying potential root causes for items of structural test information obtained for a plurality of semiconductor devices; 2) statistically analyzing the items of structural test information to identify at least one non-random device failure signature within the items of structural test information; and 3) identifying from the potential root causes a probable root cause for at least a first of the at least one non-random device failure signature.
