Abstract
A method provides a design layout having a pattern of features. The design layout is transferred onto a substrate on a semiconductor substrate using a mask. A scanning parameter is determined based on the design layout. An image of the substrate is generated using the determined scanning parameter. A substrate defect is identified by comparing a first number of closed curves in a region of the image and a second number of polygons in a corresponding region of the design layout.
