Abstract

PURPOSE: To provide a resin composition for the encapsulation of semiconductors, having low linear expansion coefficient, excellent thermal conductivity, and improved spiral flow length and flashing characteristics, by compounding a specific epoxy resin, a novolak resin and silica powder having specific particle size distribution.
CONSTITUTION: The objective composition is prepared by compounding (A) a novolak-type epoxy resin having an epoxy equivalent of ≤250 and a softening point of 60W120°C (e.g. o-cresol novolak epoxy resin) with (B) a novolak resin having a softening point of 60W130°C wherein the ratio of the epoxy group to the hydroxyl group in the component (A) is preferably 0.7:1W1:0.7, and (C) crystalline silica powder and/or fused silica powder wherein the amount of powder having particle diameter of ≥149μ is ≤0.5wt%, diameter of ≤44μ is ≥60% and diameter of ≤5μ is 20W55%, and the median diameter is 4W30μ. The amount of the component (C) is 60W80% of the whole composition.
