Thermosetting light-reflecting resin composition, optical semiconductor device mounting board and its manufacturing method and an optical semiconductor device

摘要

PROBLEM TO BE SOLVED: To provide a thermosetting resin composition capable of obtaining a formed tablet having excellent mechanical strength without sticking on the surface of a pestle and a mortar of a forming die when forming the tablet, a substrate for mounting an optical semiconductor using the resin composition, a method of manufacturing the same, and an optical semiconductor device.;SOLUTION: The thermosetting resin composition for light reflection comprises an epoxy resin (A), a hardener (B), a hardening catalyst (C), an inorganic filler (D), a white pigment (E), and a coupling agent (F) wherein at least one of the inorganic filler (D) and the white filler (E) contains a porous filler or a compound having oil absorbency as a constituent. Also provided are the substrate for mounting an optical semiconductor using the resin composition, the method of manufacturing the same, and the optical semiconductor device.;COPYRIGHT: (C)2009,JPO&INPIT
