18 March 2015 Topography aware DFM rule based scoring for silicon yield modeling
Author Affiliations +
DFM rule based scoring is associated with manufacturability rules checking and applying the scoring to predict the yield entitlement for an IC chip design. Achieving high DFM score is one of the key requirements to get high yield. The DFM scoring methodology is currently limited to DFM recommend rules and their associated failure rates. In contrast to failure mechanism, chemical-mechanical polishing (CMP) step topography variations places an important role to it. In this paper, we present an advanced DFM analysis flow to compute DFM score that incorporate topography variation along with recommend rule scoring using complex scoring model to increase silicon yield correlation.
