Abstract

Official abstract text for this publication.

An epoxy resin composition for semiconductor encapsulation of the present invention contains an epoxy resin (A) and a curing agent (B) and is used to encapsulate a copper wire ( 4 ) and a semiconductor element ( 1 ) connected to this copper wire ( 4 ). This epoxy resin composition is such that when a cured product of the epoxy resin composition is heated for 10 hours at 200° C., the amount of generation of a first corrosive gas that is a sulfur compound having corrosiveness to the copper wire ( 4 ) is less than or equal to 70 ppm.

First claim

Opening claim text (preview).

The invention claimed is: 1. An epoxy resin composition for semiconductor encapsulation, comprising an epoxy resin and a curing agent, said composition used for encapsulating a copper wire and a semiconductor element connected to the copper wire, wherein a cured product of the epoxy resin composition for semiconductor encapsulation is heated for 10 hours at 200° C., the amount of generation of a first corrosive gas that is a sulfur compound having corrosiveness to the copper wire…
