Abstract:
1. A light-emitting-element array, comprising: a current-blocking layer; a semiconductor layer of a first conductive type formed on the current-blocking layer, divided by an isolation trench into a first semiconductor region and a remaining semiconductor region, the remaining semiconductor region being electrically isolated from the first semiconductor region; a plurality of light-emitting elements formed by diffusion of an impurity of a second conductive type into a surface of the semiconductor layer, the light-emitting elements being disposed in an array divided by the isolation trench into segments including at least one light-emitting element each, the segments being disposed alternately in the first semiconductor region and the remaining semiconductor region; a first shared interconnecting pad electrically coupled to the light-emitting elements in the first semiconductor region by electrical paths not crossing the isolation trench; and a second shared interconnecting pad electrically coupled to the light-emitting elements in the remaining semiconductor region by electrical paths crossing the isolation trench.
