Patent ID: 8258519

Claim:
A semiconductor, comprising: a transparent layer having a first surface; a first doped layer formed over the first surface of the transparent layer, the first doped layer having a plurality of first-type electrodes formed thereon; a second doped layer formed over the first surface of the transparent layer, the second doped layer having a plurality of second-type electrodes formed thereon; and an active layer formed over the first surface of the transparent layer and disposed between the first doped layer and the second doped layer, wherein the second-type electrodes are surrounded by the first-type electrodes, wherein a distance between at least one of the first-type electrodes and a nearest other one of the first-type electrodes is greater than each of respective distances between the at least one of the first-type electrodes and more than two of the second-type electrodes, and wherein respective distances between every two adjacent first-type electrodes are substantially the same.
