Patterning With EUV Lithography Without Photoresists


A technical paper titled “Resistless EUV lithography: photon-induced oxide patterning on silicon” was published by researchers at Paul Scherrer Institute, University College London, ETH Zürich, and EPFL. Abstract: "In this work, we show the feasibility of extreme ultraviolet (EUV) patterning on an HF-treated Si(100) surface in the absence of a photoresist. EUV lithography is the leading ... » read more
