Novel Assist Layers To Enhance EUV Lithography Performance Of Photoresists On Different Substrates

By Brewer Science - 16 Aug, 2023 - Comments: 0

In EUV lithography, good resist patterning requires an assist layer beneath it to provide adhesion to prevent pattern collapse of small features and allow for higher aspect ratios. In addition, future EUV high numerical aperture (NA) is expected to require a decrease in thickness from the overall patterning stack. In this study, we are exploring a fundamentally new approach to developing an alt... » read more
