Patent ID: 8188508

Claim:
A device comprising: a semiconductor structure comprising: a light emitting layer disposed between an n-type region and a p-type region; an n-contact region and a p-contact region, wherein a cross section of the n-contact region comprises a plurality of first regions wherein portions of the light emitting layer and the p-type region are removed to expose the n-type region, wherein the plurality of first regions are separated by a plurality of second regions wherein second regions comprise a portion of the light emitting layer and a portion of the p-type region; and a trench disposed between the n-contact region and the p-contact region; a first metal contact formed over the semiconductor structure in the p-contact region; and a second metal contact formed over the semiconductor structure in the n-contact region; wherein the second metal contact is in electrical contact with at least one of the first regions in the n-contact region.
