ABSTRACT:
The present invention is to provide an epoxy resin composition for encapsulating a semiconductor having a high flame resistance without using a flame retarder and having an excellent solder reflow resistance, and a semiconductor device using the same for encapsulating a semiconductor element. An epoxy resin composition for encapsulating a semiconductor of each of the first, second and third aspects essentially comprises (A) a phenol aralkyl type epoxy resin having a phenylene structure, (B) a phenol aralkyl type phenolic resin having a biphenylene structure and (D) an inorganic filler as common components, wherein (D) the inorganic filler is contained at the rate of 84 wt % or more and 92 wt % or less of the total amount of the epoxy resin composition.
