First Claim
1. A light-emitting device for generating incoherent light, comprising:
- a substrate;
a semiconductor structure, formed on the substrate, comprising a top face, a bottom face, outer side faces, a first light-emitting part, a second light-emitting part, and light-extraction surfaces arranged for harvesting light from the semiconductor structure and being distant from the outer side faces; and
a first metallic conductor;
wherein each of the first and second light-emitting parts comprises a lower semiconductor layer on the substrate, an upper semiconductor layer on the lower semiconductor layer, and an active region between the lower and upper semiconductors for generating light;
wherein the first metallic conductor electrically connects the upper semiconductor layer of the first light-emitting part with the lower semiconductor layer of the second light-emitting part;
wherein the substrate comprises a non-semiconductor material.

Abstract
A light-emitting device for generating incoherent light comprises a substrate, a semiconductor structure, and a first metallic conductor formed on the substrate. The semiconductor structure comprises a top face, a bottom face, outer side faces, a first light-emitting part, a second light-emitting part, and light-extraction surfaces arranged for harvesting light from the semiconductor structure and being distant from the outer side faces. Each of the first and second light-emitting parts comprises a lower semiconductor layer on the substrate, an upper semiconductor layer on the lower semiconductor layer, and an active region between the lower and upper semiconductors for generating light. The first metallic conductor electrically connects the upper semiconductor layer of the first light-emitting part with the lower semiconductor layer of the second light-emitting part. The substrate comprises a non-semiconductor material.
