Patent ID: 8502260

Claim:
A semiconductor light emitting device, comprising: a semiconductor layer including a light emitting layer, a first major surface, and a second major surface formed on a side opposite to the first major surface; a first electrode provided on the second major surface in a region including the light emitting layer; a second electrode provided on the second major surface; an insulating layer provided on a side of the second major surface of the semiconductor layer, the insulating layer having a first opening reaching the first electrode and a second opening reaching the second electrode; a first interconnect layer provided in the first opening and on a face of the insulating layer on a side opposite to the semiconductor layer to connect to the first electrode; a second interconnect layer provided in the second opening and on a face of the insulating layer on a side opposite to the semiconductor layer to connect to the second electrode; a first metal pillar provided on a face of the first interconnect layer on a side opposite to the first electrode; a second metal pillar provided on a face of the second interconnect layer on a side opposite to the second electrode; an insulating film covering a side face of the first metal pillar and a side face of the second metal pillar, the insulating film having a solder wettability poorer than a solder wettability of the first metal pillar and a solder wettability of the second metal pillar; and a resin layer provided between the insulating film covering the side face of the first metal pillar and the insulating film covering the side face of the second metal pillar, the resin layer surrounding the first metal pillar and the second metal pillar, respectively, with interposing the insulating film therebetween, in a view perpendicular to the first major surface.
