Patent ID: 8217417

Claim:
An antistatic Gallium Nitride, GaN, based light emitting device, comprising: a substrate; an n-type GaN-based epitaxial layer formed on the substrate, an active layer formed on the n-type GaN-based epitaxial layer, and a p-type GaN-based epitaxial layer formed on the active layer; a GaN Schottky diode on a part of the p-type GaN-based epitaxial layer, the GaN Schottky diode comprising an undoped GaN-based epitaxial layer on said part of the p-type GaN-based epitaxial layer, an ohmic contact electrode on a part of the undoped GaN-based epitaxial layer and a Schottky contact electrode on another part of the undoped GaN-based epitaxial layer; a transparent conducting layer on another part of the p-type GaN-based epitaxial layer; an n-electrode on a part of the n-type GaN-based epitaxial layer; a p-electrode on the transparent conducting layer and electrically connected with the ohmic contact electrode; an insulation layer formed on side surfaces of the undoped GaN-based epitaxial layer, the p-type GaN-based epitaxial layer, the active layer and the n-type GaN-based epitaxial layer; and a connecting conductor on the insulation layer and another part of the n-type GaN-based epitaxial layer, and electrically connected with the Schottky contact electrode and the n-electrode.
