Exclusion zone for stress-sensitive circuit design

摘要

A semiconductor structure less affected by stress and a method for forming the same are provided. The semiconductor structure includes a semiconductor chip. Stress-sensitive circuits are substantially excluded out of an exclusion zone to reduce the effects of the stress to the stress-sensitive circuits. The stress-sensitive circuits include analog circuits. The exclusion zone preferably includes corner regions of the semiconductor chip, wherein the corner regions preferably have a diagonal length of less than about one percent of the diagonal length of the semiconductor chip. The stress-sensitive analog circuits preferably include devices having channel lengths less than about five times the minimum channel length.
