Patent ID: 8555208

Claim:
A system for implementing a reticle in a photolithography tool, comprising: a measuring station located remote from the photolithography tool, wherein the measuring station is configured to obtain qualitative data from (a) within a pattern area of a reticle that is to be used in the photolithography tool and (b) within a first unpatterned area of a perimeter region of the reticle distinct from a second area of the perimeter region of the reticle having alignment marks, and wherein the qualitative data is indicative of a surface characteristic of the reticle; and a correction module configured to receive the qualitative data and including a computer operable medium containing instructions that use the qualitative data from the pattern area and the second area of the reticle to determine a correction model for adjusting the photolithography tool to compensate for features of the reticle in the pattern area and provides the correction model to the photolithography tool.
