A die attach composition is used for bonding a silicon chip on a flat substrate. The die attach composition includes a cross-linkable epoxy resin having a rigid backbone, an epoxy siloxane resin, a fumed silica filler, an amine curing agent, and a silane coupling agent. The die attach composition is...
