Abstract:
1. A light emitting device having a circuit protection unit, comprising: a light emitting stacking layer having a first surface and a second surface; a circuit protection unit comprising a first low-resistance layer and a first potential barrier layer, wherein the potential barrier layer is disposed on a portion of the first surface of the light emitting stacking layer, and a Schottky contact or a p-n junction exists at the interface between the first low-resistance layer and the first potential barrier layer, and the circuit protection unit electrically connects with the first surface and the second surface to provide a rectifying function; a conductive layer disposed over the potential barrier layer, wherein the conductive layer electrically connects the circuit protection unit with the first surface and the second surface to provide a rectifying function; and a first electrode disposed over another portion of the first surface and electrically connected with the first low-resistance layer.
