摘要：
An epoxy resin composition comprising (A) a naphthalene ring-containing epoxy resin, (B) a specific phenolic resin preferably in admixture with a conventional phenolic resin, especially naphthalene ring-containing phenolic resin, and (C) an inorganic filler shows good flow and cures to products having low modulus of elasticity, a low coefficient of expansion, high Tg irrespective of low stresses, and minimized water absorption. Then semiconductor devices encapsulated with the present composition remain highly reliable even after being subject to thermal shocks upon surface mounting.
