ABSTRACT:
Disclosed is a positive-working resist composition which demonstrates improved photospeed and rate of development. The resist composition contains a solvent and select proportions of a novolak resin, a naphthoquinone diazide sensitizer, a dye which absorbs light at a maximum wavelength of from about 330 to about 460 nm and an effective proportion of a trihydroxybenzophenone compound. Also disclosed is a method of forming a resist pattern on a substrate by employing the positive-working resist composition.
