Abstract

A method for inspecting features on a reticle is provided. The method includes providing a layout design of a test feature and transferring the layout design of the test feature onto the reticle. After the test feature is transferred onto the reticle, an image of the transferred layout design is captured to determine whether or not the transfer is acceptable. This determination is made by comparing the captured image of the transferred layout design against the layout design of the test feature. The comparison ascertains deviations between the captured image and the layout design and determines if the deviations fall within a user specified range.
