Abstract
An epoxy resin composition comprising a crystalline epoxy resin, a phenolic resin, and an inorganic filler is improved in moldability by previously reacting phenolic hydroxyl groups on the phenolic resin with epoxy groups on the crystalline epoxy resin to form a reaction product and blending the reaction product in the composition. The composition is moldable over semiconductor devices without voids and wire flow. The encapsulated semiconductor devices thus remain reliable.
