摘要: Disclosed herein is an epoxy resin compound including an epoxy resin (A), a hardener (B), and an inorganic filler, characterized in that said inorganic filler contains silica (C) as an essential component, said hardener (B) is one which contains at least two phenolic hydroxyl groups and/or naphtholic hydroxyl groups in the molecule, and said silica (C) contains 1-99 wt % of synthetic silica and 99-1 wt % of natural fused silica. Disclosed also herein is a semiconductor device having a semiconductor element sealed therein with said epoxy resin compound. The epoxy resin compound does not cause such troubles as short shot, resin peeling, wire breakage, stage shift, and vent clogging at the time of molding. In addition, when used as a sealing material, it yields semiconductor devices which have good reliability at high temperature and high humidity and good resistance to soldering heat.

摘要: Disclosed is an epoxy resin composition suitable for sealing a semiconductor, comprising an epoxy resin (A), a hardener (B), an inorganic filler (C), and a phosphoric acid ester compound (D), an amount of the inorganic filler (C) contained being more than 80% by weight relative to the composition. A semiconductor sealing epoxy resin composition excellent in flame retardancy, formability, reliability and solder heat resistance is obtained without an essential need to use a halogen-based flame retardant or an antimony-based flame retardant.
