ABSTRACT:
A light-emitting element, or array of light-emitting elements, is formed by diffusion of an impurity into a semiconductor substrate, creating a light-emitting region. Following the diffusion, the surface zone of the light-emitting region, which includes crystal defects caused by the diffusion process, is removed by etching, thereby increasing the light-emitting efficiency by removing nonradiative recombination centers.
