Abstract (en)
[origin: WO2015174924A1] Various embodiments provide a method of forming a light-emitting device. The method may include providing a multi-layer structure, wherein the multi-layer structure includes a substrate, a first semiconductor layer of a first conductivity type, an active layer and a second semiconductor layer of a second conductivity type in sequence, and includes at least one metal contact formed on at least one of the first semiconductor layer and the second semiconductor layer. The method further includes forming at least one trench over the at least one metal contact, and forming at least one metal support in the at least one trenches.
