Abstract:
A light emitter having a rectangular outside shape provided with;a substrate, at least one semiconductor layer of a first conductivity type formed on the substrate, at least one semiconductor layer of a second conductivity type formed on a partial region of the semiconductor layer of the first conductivity type, a first bonding electrode connected to the semiconductor layer of the first conductivity type, and a second bonding electrode connected to an almost entire surface of the semiconductor layer of the second conductivity type, the light emitter being characterized in that the substrate is transparent to light emitted from a proximity of a junction between the semiconductor layer of the first conductivity type and the semiconductor layer of the second conductivity type, the second bonding electrode is formed to have an almost rectangular shape and a minimum area for bonding of about 50 to 300 micrometers in length and about 50 to 300 micrometers in width, and three sides of the second bonding electrode agree with three sides of the light emitter.
