Abstract:
1. A semiconductor light-emitting device comprising: a semiconductor multilayer film in which a first conductive-type layer, a light-emitting layer, and a second conductive-type layer are formed in the indicated order, and the second conductive-type layer is arranged on a light extraction side of the light-emitting layer; a base material for supporting the semiconductor multilayer film; a first electrode formed in contact with the first conductive-type layer; a second electrode formed in contact with the second conductive-type layer; a first feed terminal connected electrically to the first conductive-type layer; and a second feed terminal connected electrically to the second conductive-type layer, wherein a first conductor pattern and a second conductor pattern are formed on a principal surface of the base material that faces the semiconductor multiplayer film, the first conductor pattern is connected electrically to the first electrode, the second conductor pattern is connected electrically to the second electrode, a protruding portion is formed on a back surface of the base material that is opposite to a principal surface facing the semiconductor multilayer film, stepped portions are formed in corners of the back surface other than the protruding portion, the first feed terminal and the second feed terminal are provided on the stepped portions, the first feed terminal is connected electrically to the first conductor pattern through a first via conductor that is formed in a first through-hole formed in the base material, the second feed terminal is connected electrically to the second conductor pattern through a second via conductor that is formed in a second through-hole formed in the base material, and an end face of the protruding portion is insulated electrically from the first feed terminal and the second feed terminal.
