<p>A photoresist composition comprising a novolac resin in which 3-27 mol% of the hydroxyl group hydrogens are substituted with 1,2-naphthoquinonediazidosulfonyl groups and an alkali-soluble cellulose whose glucose ring substituent groups are substituted with organic groups at a specific rate is used in microprocessing as a positive photoresist and offers many advantages including uniformity, high sensitivity, high resolution, good pattern shape, heat resistance, film retention, substrate adhesion, shelf stability, and high throughput.</p> |
