Abstract:
1. A method of forming a pattern on a reticle substrate, the method comprising: modulating light directed to a first portion of a photosensitive layer using a plurality of tilted mirrors in a mirror array wherein each of the tilted mirrors are included as part of a piston displacement element so that a combination of tilting of the mirrors and a relative displacement of the mirrors combine to create varying degrees of interference of light waves on an image, the amount of interference corresponding to a combination of a degree of tilting and a degree of displacement; and modulating light directed to a second portion of a photosensitive layer using the plurality of tilted mirrors in the mirror array wherein each of the tilted mirrors are included as part of the piston displacement element so that the combination of tilting of the mirrors and the relative displacement of the mirrors combine to create varying degrees of interference of light waves on the image, the amount of interference corresponding to a combination of the degree of tilting and the degree of displacement.
