Abstract

The paper presents a description and results of the use of a new method to determine a capability to detect defects such as pinholes and pindots in order to test reticle and photomask inspection systems EM-6029B and EM-6329 using a die-to-database comparison method. In the introductory part given are the reasons for the necessity to determine a probability to detect defects with sizes smaller than the tool detection threshold, as well as given are the grounds for the necessity to precisely determine a scope of tests required to determine this probability. In the main part presented is a method of testing the equipment with the purpose to determine a probability to detect defects such as a pindot and a pinhole, including a procedure to estimate a required number of experiments to verify the probability to detect features of different sizes with a given confidence coefficient.
