Abstract:
1. A process for producing a semiconductor device comprising a circuit formation step of forming circuit wiring on a semiconductor wafer using a chemically-amplified resist, and a cured film formation step of forming a cured film that protects the circuit wiring after forming the circuit wiring, the cured film being formed of a cured material of a photosensitive resin composition that comprises polybenzoxazole precursor resin, a compound that generates an acid upon exposure to light, and a solvent, the photosensitive resin composition containing N-methyl-2-pyrrolidone in an amount of 1 wt % or less, and the polybenzoxazole precursor resin being obtained by reacting a dicarboxylic acid and 1-hydroxybenzotriazole in N-methyl-2-pyrrolidone to obtain a dicarboxylic acid derivative, and reacting the dicarboxylic acid derivative and a diamine in a solvent other than N-methyl-2-prryolidone.
