Abstract

The invention relates to an epoxy resin composition for semiconductor encapsulation comprising at least an epoxy resin, hardener, inorganic filler, and accelerator, wherein said epoxy resin is one which is composed of about 20 to about 90 parts by weight of 4,4'-bisphenol F type epoxy resin and about 10 to about 80 parts by weight of either a polyhydric phenolic type epoxy resin which has slightly polar hydrocarbon groups (Z) lying between the phenyl nuclei, or a biphenol type epoxy resin.
