Title:
EPOXY RESIN COMPOSITION FOR SEMICONDUCTOR ENCAPSULATION AND SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/095914
Kind Code:
A1
Abstract:
Disclosed is an epoxy resin composition for semiconductor encapsulation comprising an epoxy resin (A), a phenol resin (B), an inorganic filler (C), a curing accelerator (D) and a surface-treated coloring agent (E) wherein the coloring agent before surface treatment is composed of a carbon precursor having a carbon content of not less than 90% by weight or a carbon black having a DBP absorption of not less than 100 cm3/100g. Also disclosed is a semiconductor device encapsulated by using such an epoxy resin composition. This epoxy resin composition for semiconductor encapsulation exhibits excellent laser marking properties without causing short-circuits of wiring, electrical defects such as leakage defects, or wire deformation.
