Abstract:
1. A method for forming a pattern on a semiconductor device comprising the steps of: (a) coating an organic anti-reflective coating composition on a top portion of a film layer to be etched, wherein the organic anti-reflective coating composition comprises: (b) conducting a baking process for the obtained material to generate cross-linkage bonds and form a resultant organic anti-reflective coating; (c) applying a photoresist on a top portion of the organic anti-reflective coating, exposing and developing the photoresist to produce a desired photoresist pattern; and (d) etching the organic anti-reflective coating by using the obtained photoresist pattern as an etching mask and, in turn, the film layer to be etched, thereby forming a pattern on the film layer to be etched.
