Abstract

This paper presents the results for very detailed studies ofpattern and timing-dependent failures from the 309 dies inthe retest of an experimental test chip. 22 out of the 50CUTs with pattern-dependent failures had test escapes ifthe test sets were reordered. Some timing-dependentfailures became timing-independent combinational (TIC)defects at very low voltage. Multiple-detect single stuckfault test sets have high transition fault coverage. Mostdies with TIC or non-TIC defects were close to grossfailures or next to the wafer periphery.
