Paper Abstract

Systematic yield detractors are normally expected to be identified by ATPG test result diagnostics. Different test patterns have been designed to test different functions. Test diagnostics can identify failed functions so that product engineers, based on testing results, can narrow down which block in the design performs this function. However, it is often hard to narrow down to a more specific region in a product.

This paper will present a working flow for using design diffing techniques to extract layout structures and perform a geometry analysis flow combined with testing results to find most probable suspects that may cause noticeable yield loss.
