A liquid epoxy resin composition comprising (A) a liquid epoxy resin, (B) a curing agent, (C) a curing accelerator, and (D) an inorganic filler is provided, the curing agent (B) comprising 5 to 75 parts by weight of a mixture of 3,4-dimethyl-6-(2-methyl-1-propenyl)-1,2,3,6-tetrahydrophthalic acid and 1-isopropyl-4-methyl-bicyclo[2.2.2]oct-5-ene-2,3-dicarboxylic acid per 100 parts by weight of the entire curing agent. The composition is adherent to the surface of silicon chips, and especially to polyimide resins and nitride films and has high thermal shock resistance. A semiconductor device sealed with the cured epoxy resin composition remains reliable.
提供了一种液体环氧树脂组合物,包括(A)液体环氧树脂、(B)固化剂、(C)固化促进剂和(D)无机填料,其中固化剂(B)包括按重量计每 100 份固化剂中含 5 至 75 份 3,4-二甲基-6-(2-甲基-1-丙烯基)-1,2,3,6-四氢邻苯二甲酸和 1-异丙基-4-甲基-双环[2.2.2]辛-5-烯-2,3-二羧酸。这种组合物能附着在硅芯片表面,特别是聚酰亚胺树脂和氮化膜表面,并具有很高的抗热震性。用固化的环氧树脂组合物密封的半导体器件仍然可靠。
