Photosensitive composition and resin-encapsulated semiconductor device.

摘要

A photosensitive composition contains a polyimide constituted by a repeating unit having a hydroxyl group and a repeating unit having a siloxane bond, or a repeating unit having a hydroxyl group, a repeating unit having a siloxane bond, and a repeating unit other than these two repeating units, and a photosensitive agent consisting of an ester compound or an amide-ester compound of naphthoquinonediazidesulfonic acid or benzoquinonediazidesulfonic acid. The photosensitive composition is used as a passivation film of a semiconductor device or a photoresist.
