Abstract:
1. A quasi-vertical light emitting device comprising: a sapphire substrate; a plurality of semiconductor layers grown on the sapphire substrate, the plurality of semiconductor layers including an n-GaN layer, an active layer, and a p-GaN layer; a plurality of holes etched in the plurality of semiconductor layers, each of the plurality of holes etched to the sapphire substrate, and a plurality of blind holes in the sapphire substrate, each of the plurality of holes aligned with one of the plurality of blind holes to form hole walls, the hole walls plated with an n-metal and each of the plurality of blind holes filled with an n-metal to form an n-electrode contact an n-mesa in the active layer and the p-GaN layer, the n-mesa plated with an n-metal and a passivation layer grown over the n-metals; and a p-metal layer deposited on the p-GaN layer, and a p-electrode bonded to the p-metal.
