Abstract:
Provided is a film adhesive which is preferably used as a NCF, void-free, has excellent electrical connectivity and its high reliability, does not develop cracks easily, and has high surface flatness. Also provided is a semiconductor device in which the film adhesive according to the present invention is used as an NCF during the manufacture of the semiconductor device. The film adhesive according to the present invention contains (A) an epoxy resin; (B) a bisphenol F type phenoxy resin; (C) a phenol resin-based curing agent; (D) a modified imidazole compound; (E) a silica filler; (F) oxyquinoline; and (G) a butadiene-acrylonitrile-methacrylic acid copolymer. The content of component (A) is 19.3 to 33.8 parts by mass. The content of component (B) is 7.5 to 9.1 parts by mass. The content of component (D) is 1.915 to 5 parts by mass. The content of component (E) is 30 to 60 parts by mass. The content of component (F) is 2.5 to 10 parts by mass. The liquid epoxy resin of component (A) contains a phenol novolac type epoxy resin and a liquid epoxy resin. The ratio of phenol novolac type epoxy resin to the epoxy resin of component (A) is not less than 46%. The equivalent ratio of component (C) relative to component (A) is 0.25 to 0.75.
