ABSTRACT:
Disclosed is a photosensitive resin composition for forming a polyimide film pattern. The composition contains a polyamic acid and at least one silyl ketone compound represented by general formula (II) given below, ##STR1## where each of R.sup.3 to R.sup.16 is a are substituted or unsubstituted alkyl group having 1 to 12 carbon atoms or a substituted or unsubstituted aromatic group having 6 to 14 carbon atoms, each of R.sup.5 to R.sup.16 may be a substituted or unsubstituted silyl group, and each of l, m, n, s, t and u is 0 or 1, at least one of l, m, n, s, t and u being 1. The composition further contains a sensitizer, as required. A semiconductor substrate is coated with the composition, followed by exposing the coating through a predetermined mask and subsequently developing and heat-treating the coating so as to form a polyimide film pattern.
