Abstract:
1. A resin-encapsulated semiconductor apparatus comprising: a semiconductor device having a ferroelectric film and a surface-protective film, and an encapsulant member comprising a resin; wherein said surface-protective film consists of a heat-cured polyimide prepared by heat-curing a polyimide precursor containing: a polyimide acid comprising repeating units represented by a chemical formula (I) as given below; an amine compound having carbon-carbon double bonds; and a photopolymerization initiator and/or a sensitizer wherein an amount of said amine compound is 1 to 400 parts by weight based on 100 parts by weight of said polyimide precursor and a total amount of said photopolymerization initiator and said sensitizer is 0.1 to 30 parts by weight based on 100 parts by weight of said polyimide precursor; wherein R
