ABSTRACT:
A positive resist composition containing a quinone diazide compound and an alkali-soluble resin which contains a resin (A) obtained by a condensation reaction of an aldehyde compound, at least one phenol compound of the formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are independently a hydrogen atom, or a C.sub.1 -C.sub.4 alkyl or alkoxy group, and j is 1 or 2, and at least one compound of the formula: ##STR2## wherein R'.sub.1, R'.sub.2, R'.sub.3, R'.sub.4, R'.sub.5 and R'.sub.6 are independently a hydrogen atom, or a C.sub.1 -C.sub.4 alkyl or alkoxy group, R'.sub.7 is a hydrogen, a C.sub.1 -C.sub.4 alkyl group or an aryl group, and k, m and n are independently 0, 1 or 2 provided that a sum of k, m and n is larger than 2, which composition is excellent in balance among various properties such as a profile, a sensitivity, heat resistance and a depth of focus.
