A method of forming a resist pattern in a semiconductor device layer includes forming a buffer layer on a semiconductor device layer and forming a resist layer on the buffer layer. A decomposing agent is released into a portion of the buffer layer by a portion of the resist layer whereupon the portion of the buffer layer and the portion of the resist layer are removed to form a process window substantially free of resist residue that can be subsequently exploited for etching of the semiconductor device layer.

A method for semiconductor manufacturing includes forming an overlay target having a pattern formed by a first mask layer and an adjacent layer. The overlay target is exposed to radiation. As a result, reflective beams can be detected from the pattern and the adjacent layer and the location of the pattern can be identified based on the reflective beams.
