Abstract:
1. A structure, comprising: a substrate having a mesa; an active region on the substrate adjacent the mesa; a first metal seed layer on the mesa in electrical contact with an n-type semiconductor; a second metal seed layer on the active region on the substrate in electrical contact with a p-type semiconductor and isolated from the first metal seed layer; a passivation layer on the substrate and the seed layers; and at least one electroplated, metal contact pad in contact with the first metal seed layer and at least one electroplated, metal contact pad in contact with the second metal seed layer such that there is contiguous contact between the metal contact pads and the passivation layer and between the seed layers and the passivation layer, the metal contact pad in contact with the first metal seed layer and the metal contact pad in contact with the second metal seed layer being on a same plane.
