Abstract
An n-type layer, an active layer, and a p-type layer are grown on a growth substrate. Portions of the p-type layer and active layer are etched away to expose the n-type layer, and an n-electrode is formed over the exposed portions of the n-type layer. A first dielectric layer is formed over the n-electrodes. A transparent conductor layer is formed over the p-type layer and the first dielectric layer. A p-electrode is formed over the transparent conductor layer. A transparent bonding layer is deposited over the transparent conductor layer and the p-electrode. A transparent support substrate is bonded to the p-type layer via the bonding layer. The growth substrate is then removed to expose the n-type layer, and the layers are etched to expose the n and p electrodes for connection to a power source. A reflector layer is formed on the bottom surface of the substrate.
