Latest Patents

JyhChiarng Wu holds a patent for a "Light emitting diode having increased light extraction." This invention involves a complex structure where 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, allowing for the formation of an n-electrode over the exposed portions. A first dielectric layer is then formed over the n-electrodes, followed by a transparent conductor layer over the p-type layer and the first dielectric layer. The p-electrode is formed over the transparent conductor layer, and a transparent bonding layer is deposited over these components. A transparent support substrate is bonded to the p-type layer via the bonding layer. After removing the growth substrate, the layers are etched to expose the n and p electrodes for connection to a power source. Finally, a reflector layer is formed on the bottom surface of the substrate.
