Patent ID: 7441226

Claim:
A method of programming defect data for evaluation of a reticle inspection apparatus, comprising the steps of: inputting a program defect condition to a defect-data programming apparatus which programs defect data for evaluation of said reticle inspection apparatus, thereby generating program defect information; converting program-defect-information-free source CAD data to CAD data of a format with which the CAD data is input to said reticle inspection apparatus and embedding said program defect information into said converted CAD data, thereby generating program-defect-information-present CAD data for inspection apparatus; and inputting said program-defect-information-present CAD data for inspection apparatus and a program-defect-information-free reticle produced based on said program-defect-information-free source CAD data, to said reticle inspection apparatus to execute sensitivity evaluation, whereby program defect information needed to execute sensitivity evaluation of said reticle inspection apparatus is generated on that CAD data which is input to said reticle inspection apparatus, not on a real reticle.
