Patent ID: 6958498

Claim:
A light-emitting diode comprising: (a) a structure including (i) a region of n-type semiconductor; and (ii) a region of p-type semiconductor overlying the n-type region and defining a top surface remote from the n-type region, the structure defining an active light-emitting region between the n-type region and the p-type region, said structure having edges bounding said top surface; (b) a p-type electrode-pad unit including a p-electrode and a p-pad, the p-electrode being disposed on the top surface and the p-pad being disposed on the p-electrode; (c) an elongated trench extending into said structure from said top surface through the p-type region and the active light-emitting region to the n-type region, the elongated trench being entirely surrounded by the p-electrode; and (d) an n-type electrode pad unit including (i) an elongated n-electrode disposed in the elongated trench in contact with said n-type region; and (ii) a plurality of n-pads disposed on the elongated n-electrode and distributed along the elongated trench, the n-pads being entirely surrounded by the p-electrode.
