In the photomask process, Zero E-field borders have been used on attenuated/embedded phase shift masks to provide an opaque area around the die area in the mask industry, but this border has never been able to be inspected on a laser scan inspection tool. This paper reports the first time that the Zero E-field has been inspected at DuPont Photomasks, Reticle Technology Center.
