EPOXY RESIN COMPOSITION FOR OPTICAL APPLICATIONS CAPABLE OF OFFERING PRODUCTS WITH HIGH RELIABILITY WHEN USING AS THE SEALING MATERIAL OF THE FORMING MATERIAL OF OPTICAL COMPONENTS OR OPTICAL SEMICONDUCTOR DEVICE, AND OPTICAL COMPONENTS AND OPTICAL SEMICONDUCTOR DEVICE USING THE SAME

摘要

PURPOSE: An Epoxy resin composition for optical application has the low temperature dependency of light transmission, and provided to reduce the change of light transmission against the temperature.;CONSTITUTION: An epoxy resin composition for optical application comprises an epoxy resin, hardener, and inorganic filler. The inorganic filler comprises: an inorganic filler having refractive index greater than the refractive index of hardening material which is obtained from epoxy resin composition except inorganic filler; and an inorganic filler having refractive index smaller than the refractive index of hardening material which is obtained from epoxy resin except inorganic filler. The maximum difference of refractive index between a plurality of inorganic fillers is 0.15 or less.;COPYRIGHT KIPO 2012
