Abstract

Methodologies and a device for assessing integrated circuit and pattern for yield risk based on 3D simulation of semiconductor patterns are provided. Embodiments include generating, with a processor, a 3D simulation of semiconductor patterns; obtaining critical dimensions of distances between layers or within a layer of the 3D simulation of semiconductor patterns; comparing the set of critical dimensions with predefined minimum dimensions; and yield scoring each of the semiconductor patterns of the 3D simulation based on the comparing step.
