Abstract
Embodiments of the present disclosure generally provide a method and apparatus for forming features in a material layer utilizing EUV technologies. In one embodiment, a method of patterning a substrate includes disposing a patterned photoresist layer on a mask layer disposed on a substrate, wherein the patterned photoresist layer has openings with different widths defined in the patterned photoresist layer, forming a compensatory layer along sidewalls of the patterned photoresist layer to modify the widths of the openings and etching the mask layer through the openings with the modified width.
