Paper Abstract
Defect printability of attenuated phase-shifting masks for a dot defect in isolated hole and space patterns is evaluated by EDM (exposure-defocus and mask fabrication latitudes) process windows and process latitude functions which are derived from a series of EDM windows. The allowable defect size is confirmed to be 0.08 (lambda) /NA both for the hole and space patterns with the practical process latitude consideration. By the evaluation of the process latitude functions, it is found that an influence range by the dot defect is extended up to 20 times of the defect size in units on a wafer.
