TRANSPARENT RESIN COMPOSITION AND METHOD FOR PRODUCING THE SAME, AND OPTICAL SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a transparent resin composition in which an inorganic filler having a small particle diameter is sufficiently dispersed and which has high transparency and excellent heat resistance, dimensional stability and the like and a method for producing the same and to provide an optical semiconductor device sealed by a cured product of the composition. SOLUTION: A pre-mixture (A) formed by premixing the inorganic filler having 5 to 40 nm average primary particle diameter and an epoxy resin, a pre-mixture (B) formed by premixing the inorganic filler having 5 to 40 nm average primary particle diameter and an acid anhydride curing agent and a curing promoter (C) are mixed to form the transparent resin composition. The optical semiconductor element is sealed by the cured product of the transparent resin composition. COPYRIGHT: (C)2011,JPO&INPIT
