US Patent 7161190 Semiconductor light-emitting device and method of manufacturing the same

A semiconductor light-emitting device includes a light-emitting element, a first lead frame having a main surface having the light-emitting element mounted thereon, a second lead frame spaced apart from the first lead frame, resin molded portions for fixing the first and second lead frames, and a heat-radiating member bonded to a back face of the first lead frame with a brazing member (electrically-conductive layer) containing metal interposed therebetween. The brazing member and the heat-radiating member are formed immediately below and around the light-emitting element.
