Patent ID: 7875984

Claim:
A structure comprising: a light emitting device comprising: a semiconductor structure comprising a light emitting layer disposed between an n-type region and a p-type region; a metal p-contact disposed on the p-type region; and a metal n-contact disposed on the n-type region; wherein: the metal p-contact and the metal n-contact are both formed on a same side of the semiconductor structure; and one of the metal p-contact and the metal n-contact is a large area contact and the other of the metal p-contact and the metal n-contact is a small area contact, the large area contact having a larger area than the small area contact; a mount; and a bonding structure connecting the light emitting device to the mount, wherein in an area underlying the small area contact, the bonding structure comprises a plurality of metal regions separated by gaps, wherein nearest neighbor metal regions are separated by a gap less than 5 microns wide.
