Abstract

See full text

A light-emitting device includes a substrate including a top surface, a first side surface and a second side surface, wherein the first side surface and the second side surface of the substrate are respectively connected to two opposite sides of the top surface of the substrate; a semiconductor stack formed on the top surface of the substrate, the semiconductor stack including a first semiconductor layer, a second semiconductor layer, and an active layer formed between the first semiconductor layer and the second semiconductor layer; a first electrode pad formed adjacent to a first edge of the light-emitting device; and a second electrode pad formed adjacent to a second edge of the light-emitting device, wherein in a top view of the light-emitting device, the first edge and the second edge are formed on different sides or opposite sides of the light-emitting device, the first semiconductor layer adjacent to the first edge includes a first sidewall directly connected to the first side surface of the substrate, and the first semiconductor layer adjacent to the second edge includes a second sidewall separated from the second side surface of the substrate by a distance.
