Abstract:
PROBLEM TO BE SOLVED: To provide a positive photosensitive resin composition suitable for the formation of an interlayer insulating film having high heat resistance, high solvent resistance, high transmittance and a low dielectric constant, and having a large development margin that allows formation of a favorable pattern even when a developing time exceeds the optimal developing time in a developing process.SOLUTION: A positive photosensitive resin composition contains a polysiloxane compound having a carboxyl group and/or a phenolic hydroxyl group as a base resin, a photosensitive diazoquinone compound as a photosensitive component, and an organic solvent, into which an epoxy siloxane compound is incorporated. The epoxy siloxane compound comprises groups of a cyclic siloxane structure having an epoxy group connected via a residue of a compound having 2 to 4 vinyl groups per molecular from which the vinyl groups are removed.
