Abstract:
1. A light emitting diode (LED) chip, comprising: a substrate; a GaN-based compound semiconductor stacked structure arranged on the substrate, the semiconductor stacked structure comprising a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer; an electrode electrically connected to the semiconductor stacked structure; and a wavelength converting layer covering a portion of the semiconductor stacked structure, wherein the electrode passes through the wavelength converting layer, wherein the electrode comprises a first electrode arranged on the semiconductor stacked structure, and a first additional electrode arranged on the first electrode, wherein the entire lower surface of the first additional electrode is arranged entirely on the first electrode, wherein the wavelength converting layer is disposed with a uniform thickness on side surfaces of the substrate and the GaN-based compound semiconductor stacked structure, and wherein the side surfaces of the substrate and the GaN-based compound semiconductor stacked structure are substantially flush.
