Abstract:
1. A semiconductor light-emitting device comprising: a laminated structure including, a first semiconductor layer, a second semiconductor layer, and a light-emitting layer provided between the first semiconductor layer and the second semiconductor layer, the second semiconductor layer and the light-emitting layer being selectively removed and a part of the first semiconductor layer being exposed to a first main surface on a side of the second semiconductor layer; a first electrode provided on the first main surface of the laminated structure and connected to the first semiconductor layer and including a first metal film provided on the part of the first semiconductor layer and a second metal film provided on the part of the first semiconductor layer, the first metal film physically contacting with the first semiconductor layer, the second metal film physically contacting with the first semiconductor layer, the first metal film having a first reflectance for light emitted from the light emitting layer, the second metal film having a second reflectance for the light higher than the first reflectance, and the first metal film having a first contact resistance with respect to the first semiconductor layer, the second metal film having a second contact resistance with respect to the first semiconductor layer, the second contact resistance being higher than the first contact resistance; a second electrode provided on the first main surface of the laminated structure and connected to the second semiconductor layer; and a dielectric laminated film provided on a surface of the first semiconductor layer and the second semiconductor layer, the surface being not covered with any one of the first electrode and the second electrode on the first main surface, the dielectric laminated film having a plurality of dielectric films having different refractive indices being laminated, wherein the first metal film opposes the second electrode, the second metal film is disposed on an opposite side of the first metal film to the second electrode, and top surfaces of the first and second metal films are substantially coplanar and directly adjacent to each other.
