An epoxy resin composition for semiconductor encapsulation containing at least an epoxy resin, hardener, inorganic filler, and accelerator, wherein said epoxy resin is one which is composed of 20-90 parts by weight of 4,4'-bisphenol F type epoxy resin and 10-80 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.
The composition is superior in fluidity and gives a cured product having low moisture absorption and good solder crack resistance and heat resistance. It is suitable for encapsulation of semiconductors.

The present invention provides a tetramethylbiphenyl type high performance epoxy resin composition and a curable epoxy resin composition containing the epoxy resin, useful in electrical and electronic fields and the like. The tetramethylbiphenyl type epoxy resin composition comprises an epoxy resin composition obtained by reacting 4,4′-dihydroxy-3,3′, 5,5′-tetramethylbiphenyl and an epihalohydrin in the presence of an alkali metal compound. The composition has a content of tetramethyldiphenoquinone of 0.5% by weight or less and a content of a glycidyl compound represented by the following structural formula (1):
1
of 0.5% by weight or less. The curable epoxy resin composition contains the epoxy resin composition and a hardener for the epoxy resin.
