    摘要: Epoxy resin compositions comprising (A) a crystalline epoxy resin, (B) a polyfunctional phenolic resin, (C) an organic phosphorus curing accelerator, (D) an aminosilane coupling agent, and (E) at least 88 wt % based on the composition of an inorganic filler are smoothly flowing, fast curing and shelf stable. Due to minimized package warp, minimized wire flow, improved adhesion, and low water absorption, the compositions enable highly reliable encapsulation of semiconductor devices, especially BGA.

    摘要: Epoxy resin compositions comprising (A) a polyfunctional epoxy resin, (B) a polyfunctional phenolic resin curing agent, (C) an organophosphorus curing accelerator, (D) an aminosilane coupling agent, and (E) an inorganic filler have excellent flow properties, shelf stability and curing speed and are thus suitable for semiconductor encapsulation, especially BGA encapsulation. Semiconductor devices encapsulated with the epoxy resin compositions are highly reliable.

    摘要: Novel fluorine-modified acid anhydrides of formula (1) are useful curing agents typically in epoxy resin compositions for encapsulating semiconductor devices. ##STR1## R.sup.1 is a hydrogen atom, substituted or unsubstituted monovalent hydrocarbon group, hydroxyl group, alkoxy group or alkenyloxy group. Rf is a divalent perfluoroalkylene or perfluoropolyether group of the general formula (2): ##STR2## wherein l is an integer of 0 to 8, k and m are integers of 0 to 15, j and n are 0 or 1, with the proviso that j, k, l, m and n are not equal to 0 at the same time.
