Patent Images
1. A method for determining an image, comprising:
- receiving a mask pattern;
receiving a first image of at least a portion of a photo-mask corresponding to the mask pattern; and
determining a second image of at least the portion of the photo-mask in accordance with the first image and the mask pattern, wherein the second image is characterized by additional spatial frequencies than the first image.

Abstract
A system receives a mask pattern and a first image of at least a portion of a photo-mask corresponding to the mask pattern. The system determines a second image of at least the portion of the photo-mask based on the first image and the mask pattern. This second image is characterized by additional spatial frequencies than the first image.
