Abstract:
PROBLEM TO BE SOLVED: To provide a radiation sensitive resin composition which has high transparency to radiations, and has excellent basic properties as a resist, such as sensitivity, dry etching resistance and pattern shapes, more particularly excellent solubility in a resist solvent and reduces the roughness of pattern side walls after development. SOLUTION: The radiation sensitive resin composition contains an acid dissociative group-containing resin which is insoluble in an alkali or hardly soluble in the alkali and is made easily soluble in the alkali by the effect of an acid and a radiation sensitive acid forming agent. The dissociative group-containing resin includes the recursive unit expressed by formula (1) and the ratio (Mw/Mn) of the weight average molecular weight and number average molecular weight thereof is COPYRIGHT: (C)2004,JPO&NCIPI
