A semiconductor light emitting device includes a substrate having a main surface and an exposed surface; an epitaxial structure, disposed on the main surface of the substrate, having at least a first type semiconductor layer, a light-emitting layer, and a second type semiconductor layer, wherein the first type layer has a first sidewall including at least a first etched surface and a second etched surface, wherein angles between the etched surfaces and the exposed surface are acute angles; and an electrode structure disposed on the epitaxial structure.

Semiconductor light emitting device

A semiconductor light-emitting structure including a first conductive type semiconductor layer, a second conductive type semiconductor layer, a light-emitting layer, an electrode, an insulating layer, and an adhesive layer is provided. The light-emitting layer is disposed between the first conductive type semiconductor layer and the second conductive type semiconductor layer. The electrode is disposed on the first conductive type semiconductor layer. The insulating layer covers a part of the first conductive type semiconductor layer and the electrode. The adhesive layer is disposed between the electrode and the insulating layer so as to bond the electrode and the insulating layer.

Semiconductor light-emitting structure

The present invention discloses a method for fabricating a light emitting diode element, which incorporates an epitaxial process with an etching process to etch LED epitaxial layers bottom up and form side-protrudent structures, whereby the LED epitaxial layers have non-rectangular inclines, which can solve the problem of total reflection and promote light-extraction efficiency. Further, the method of the present invention has a simple fabrication process, which can benefit mass production and lower cost.
