Patent ID: 7754395

Claim:
A method of forming a reticle and using the reticle for multiple applications, comprising: forming the reticle to have multiple patterns tailored for multiple different applications; the reticle having a front side and a backside, the patterns being formed along the front side; one of the patterns being a first pattern tailored for a first application, and another of the patterns being a second pattern tailored for a second application; applying masking material across a portion of the backside of the reticle to block light from passing through at least part of the second pattern during a first photolithographic process to photolithographically pattern a first substrate; after the first photolithographic process, removing the masking material from across the portion of the backside of the reticle; and after removing the masking material from across the portion of the backside of the reticle, passing light through an entirety of said second pattern during a second photolithographic process to photolithographically pattern a second substrate.
