ABSTRACT:
An epoxy resin composition comprising (A) an epoxy resin having at least two epoxy groups in a molecule, (B) a phenolic resin having at least one naphthalene ring in a molecule, and (C) an inorganic filler has improved flow and cures into products having a low coefficient of expansion, high Tg, and low moisture absorption. The composition is thus suitable for encapsulating semiconductor devices.
