摘要:
An LOC structure semiconductor device having a good solder heat resistance without electrical characteristic failures due to damages to the passivation film and the diffusion layer thereunder attributing to the filler can be obtained by encapsulating an LOC structure semiconductor chip with an encapsulating material comprising an epoxy resin, a curing agent, a curing promoter, and an inorganic filler, the filler having a smaller particle size than the distance between a inner lead and a semiconductor chip and being in an amount of 80 to 95% by weight based on the total weight of the encapsulating material.
摘要:
An epoxy resin composition for semiconductor sealing, which comprises an epoxy resin, a curing agent and an inorganic filler, and has a J-value of 10 to 50, which is a maximum jetting flow value determined according to a method of evaluating jetting flow of epoxy resin composition.
