Abstract

In this paper a novel approach for yield optimization is presented. While there are
di®erent types of defects or other issues a®ecting the yield, only the "extra conductive
material" type (potentially causing shorts circuits) is studied. The approach tends to
improve the yield of the IC layout by reducing the area which is sensitive to random
defects, the so-called critical area.
