ABSTRACT:
A semiconductor light emitting apparatus includes a non-conductive sub mount; a metal layer provided on the sub mount; a solder material member provided on the metal layer; and a semiconductor light emitting device die-bonded to the metal layer by the solder material member. A surface of the metal layer includes a solder material attachment area having the solder material member attached thereto, and a metal layer exposed area where the surface of the metal layer is exposed. The solder material attachment area is electrically connected to the metal layer exposed area. The solder material attachment area is larger than a die-bond area of the semiconductor light emitting device. The metal layer exposed area has a metal layer removed area therein where the sub mount is exposed.
