Abstract
A method of generating a layout pattern includes disposing a photoresist layer of a resist material on a substrate and disposing a top layer over of the photoresist layer. The top layer is transparent for extreme ultraviolet (EUV) radiation and the top layer is opaque for deep ultraviolet (DUV) radiation. The method further includes irradiating the photoresist layer with radiation generated from an EUV radiation source. The radiation passes through the top layer to expose the photoresist layer.
