Abstract:
1. A surface-emitting type device comprising: a substrate including a first face and a second face, the second face being tilted with respect to the first face and having a plane index different from a plane index of the first face; (1) an emission section formed above the first face, the emission section including: a first semiconductor layer of a first conductivity type, an active layer formed above the first semiconductor layer, and a second semiconductor layer of a second conductivity type formed above the active layer; (2) a rectification section formed above the second face, the rectification section including: a first semiconductor layer of the second conductivity type, and a second semiconductor layer of the first conductivity type formed above the first semiconductor layer; the first semiconductor layer of the emission section and the first semiconductor layer of the rectification section are formed by a common process and include the same impurity; the emission section and the rectification section being electrically connected in parallel with each other; and the rectification section having a voltage direction that is opposite of a voltage direction of the emission section.
