Abstract:
A computer program stored on a computer readable medium for determining the printability of a defect on a reticle or photomask onto a substrate during processing of said substrate, said printability being determined from a defect review menu of said reticle or photomask prepared by an inspection machine and weighting factors related to a fabrication procedure used to produce said substrate, said computer program comprising:a. instructions for creating a pixel grid image of a portion of said reticle or photomask containing said defect identified in said defect review menu, said pixel grid image having a plurality of associated individual pixel images of said reticle or photomask; b. instructions for assigning a gray scale value to each of said associated individual pixel images of said pixel grid image; c. instructions for selecting a probable center pixel of said defect in said pixel grid image; d. instructions for determining a polarity of said defect; e. instructions for determining a region of physical extent of said defect; and f. instructions for determining a transmissivity energy level of said region of physical extent of said defect.
