Abstract
In one embodiment, a method for detecting design defects is provided. The method includes receiving design data of an integrated circuit (IC) on a wafer, measuring wafer topography across the wafer to obtain topography data, calculating a scanner moving average from the topography data and the design data to provide a scanner defocus map across the wafer, and determining a hotspot design defect from the scanner defocus map. A computer readable storage medium, and a system for detecting design defects are also provided.
