摘要:
An epoxy resin composition comprising an epoxy resin, a curing agent, an inorganic filler, and a curing accelerator is suited for semiconductor encapsulation. A specific organic phosphorus compound is used as the curing accelerator. The composition is smoothly flowing, stable during storage, effectively curable and mold releasable and can be molded and cured into products free from wire flow and voids.
摘要:
An epoxy resin composition contains (A) an epoxy resin, (B) a phenolic resin curing agent, (C) a curing catalyst, and (D) an inorganic filler. The catalyst is a quaternary phosphorus compound or a quaternary phosphorus compound which has been mixed and reacted with a phenolic resin having at least two hydroxyl groups. The composition is effectively flowable, moldable and curable and thus suitable for semiconductor encapsulation.

An epoxy resin composition comprising (A) a biphenyl skeleton-bearing epoxy resin, (B) a biphenyl skeleton-bearing phenolic resin as a curing agent, (C) an organosiloxane containing phenyl and organooxy groups, and (D) an inorganic filler is suited for semiconductor encapsulation since it is effectively moldable and cures into a part having improved reflow crack resistance, moisture resistance, and flame retardance. It does not pose a hazard to human health or the environment.
摘要:
An epoxy resin composition comprising an epoxy resin, a phenolic resin curing agent, an inorganic filler, zinc molybdate on an inorganic support, and a complementary combination of two phosphazene compounds is effectively moldable, flame retardant and suitable for semiconductor encapsulation. A semiconductor device encapsulated with the cured epoxy resin composition is improved in flame retardance and moisture-proof reliability.
