    摘要: A resist composition comprising (a) a polymer having repeating units of the formula:
    wherein R5, R6 and R7 are independently hydrogen, alkyl, cyano, alkyloxycarbonyl or carbamoyl; Z is a spacer or a direct link; and R is hydroxyalkyl having a protected terminal hydroxy, (b) a photoacid generator, and (c) a solvent, is effective for forming patterns using ArF excimer laser beams.

    摘要: A polymer of polyhydroxystyrene derivative containing an acetal or ketal group which can easily be eliminated in the presence of an acid in the molecule and having a very narrow molecular weight distribution gives a resist material suitable for forming ultrafine patterns excellent in resolution, heat resistance, mask linearity, and other properties without causing problems of delay time and the like.
