Abstract

A photosensitive resin composition using a polyimide precursor composition, a cured film, a method for producing a cured film, a semiconductor device, and a method for producing a polyimide precursor composition are provided. In the polyimide precursor composition, the molar ratio of repeating units represented by General Formula (1-2) among structural isomers of the polyimide precursor is 60% to 90% by mole. In General Formula (1-2), Aand Aeach independently represents an oxygen atom or NH, Rand Reach independently represents a single bond or a divalent organic group, and Rand Reach independently represents a hydrogen atom or a monovalent organic group.
