Resist composition and patterning process using the same
The present invention provides a resist composition containing a base resin composed of a polymer compound that contains a repeating unit a shown by formula (1) and a repeating unit b having either or both of a carboxyl group in which a hydrogen atom is substituted with an acid-labile group and a phenolic hydroxyl group in which a hydrogen atom is substituted with an acid-labile group, with a weight average molecular weight of 1,000 to 500,000. There can be provided a resist composition that has high sensitivity and high resolution, and can give a pattern with low dimensional variation and good pattern profile after exposure. ##STR00001##
wherein R.sup.1 represents a hydrogen atom or a methyl group; Z represents a hydroxybenzoquinone group, or a hydroxynaphthoquinone group optionally containing a substituent; and a fraction a of the repeating unit a satisfies 0<a<1.0, and a fraction b of the repeating unit b satisfies 0<b<1.0.
