Abstract

The present invention provides a method of forming a dynamic template with a focused beam. The method includes forming a desired template that represents a desired image, forming an actual template that represents an actual image, such as a photolithographic mask or a semiconductor device feature, and comparing the desired template to the actual template to yield a deviation template. In one embodiment the deviation template is formed by subtracting the actual template from the desired template.
