Document Type and Number:
Japanese Patent JP3377408
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain excellent tight adhesion between a sealing resin and a lead frame, control the occurrence of peeling, and reduce the occurrence of package crack after moisture absorption and reflowing by incorporating a specified amount of a water-insoluble compound having a benzotriazole skeleton into a sealing resin composition. SOLUTION: At least a part of water-insoluble compound used comprises 1,2,3-benzotriazole represented by formula I. Water-insoluble compounds are defined as those having a solubility in water at ordinary temperature of at most about 5%, which are added in an amount of 0.01-1 wt.% based on the total composition. A biphenyl epoxy resin represented by formula II (wherein R1 to R4 are each H or methyl) is used as at least a part of epoxy resins. The curing agent used comprises a polybasic phenol compound such as phenolic novolak, or a naphthol compound. The equivalent ratio of curing agent to epoxy resin is preferably (0.5 to 1.5):1. The inorganic filler used comprises, e.g. fused silica, which is blended in an amount of preferably 70-92 wt.%.
