Abstract:
1. A fabrication method of nitride semiconductor Light Emitting Diodes (LEDs), the method comprising the following steps of: (a) forming an n-doped semiconductor layer on a substrate; (b) forming an active layer on the n-doped semiconductor layer; (c) forming a p-doped semiconductor layer on the active layer; (d) forming a p+-doped semiconductor layer on the p-doped semiconductor layer; (e) implanting n-dopant ions into the p+-doped semiconductor layer to convert at least a portion of the p+-doped semiconductor layer into an n+-doped semiconductor layer so that the n+-doped semiconductor layer cooperates with a remaining region of the p+-doped semiconductor layer to form a reverse bias tunneling junction; and (f) mesa-etching a resultant semiconductor structure to the extent of exposing a partial area of the n-doped semiconductor layer.
