An encapsulating epoxy resin molding material comprising (A) an epoxy resin, (B) a curing agent, and (C) a silane coupling agent having a secondary amino group or (D) a phosphate, and semiconductor devices encapsulated therein. The encapsulating epoxy resin molding material for thin semiconductor devices according to this invention is excellent in fluidity, and the semiconductor device encapsulated therein, which is a semiconductor device having a semiconductor chip arranged on a thin, multi-pin, long wire, narrow-pad-pitch, or on a mounted substrate such as organic substrate or organic film, is free of molding defects such as wire sweep, voids etc. as shown in the Examples, and thus its industrial value is significant.
An encapsulating epoxy resin molding material comprising (A) an epoxy resin, (B) a curing agent, and (C) a silane coupling agent having a secondary amino group or (D) a phosphate, wherein a disk flow is 80 mm or more.
An encapsulating epoxy resin molding material comprising (A) an epoxy resin, (B) a curing agent, and (C) a silane coupling agent having a secondary amino group or (D) a phosphate, wherein the encapsulating epoxy resin molding material is used for the semiconductor device having at least one of the following constitutions (a) to (f):
