NEGATIVE PHOTOSENSITIVE RESIN COMPOSITION, PHOTOSENSITIVE DRY FILM, AND LIGHT RECEIVING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a negative photosensitive resin composition which can form a photosensitive resin layer having excellent developability, resolution and adhesiveness after patterning, a photosensitive dry film which has a photosensitive resin layer comprising the composition, and a light receiving device having a spacer that is obtained by curing the composition.SOLUTION: A negative photosensitive resin composition according to the present invention suitable to forming a spacer 13 for a light receiving device 1 comprises an alkali-soluble resin (A); a compound (B) which generates an acid or a radical by irradiation of active rays; a compound (C) crosslinkable by the acid or radical; an epoxy resin (D) expressed by a general formula (D-1); and a solvent (S). (In the formula, Rand Reach independently presents a methyl group or the like; Rthrough Reach independently presents a hydrogen atom or the like; "A" represents a di(ethyleneoxy)ethyl group or the like; and "n" is a natural number and its average is 1.2-5.)
