    Abstract: PURPOSE:To obtain an epoxy resin composition for semiconductor sealing having excellent soldering heat-resistance and thermal conductivity by compounding an epoxy resin having a specific structure with a curing agent and silicon nitride and/or silicon carbide. CONSTITUTION:The objective composition is produced by compounding (A) 4-20wt.% of an epoxy resin containing >=50wt.% of an epoxy resin of formula (R to R are H, halogen or 1-4C alkyl) (e.g. 1,5-diglycidylnaphthalene), (B) 2-15wt.% of a curing agent (e.g. phenolic novolak resin), (C) 1-95wt.% of silicon nitride and/or silicon carbide and (D) 0.1-20wt.% of a styrene-based block copolymer.

    Abstract: PURPOSE:To obtain the title composition, not causing cracks in a soldering process, having excellent storage stability at room temperature and excellent reliability of water-vapor resistance by blending a biphenyl skeleton-containing epoxy resin with a curing agent having specific structure. CONSTITUTION:(A) An epoxy resin comprising an epoxy resin essentially containing skeleton shown by formula I (R to R are H, halogen or 1-4C alkyl) is blended with (B) a curing agent essentially containing a compound shown by formula II (R is H, aryl or alkyl) and (C) 75-90wt.% filler (preferably fused silica) to give the objective composition. 4,4'-Bis(2,3-epoxypropoxy)biphenyl is preferable as the epoxy resin shown by formula I. Tris(4-hydroxyphenyl) methane is preferable as the compound shown by formula II.
