Abstract: A multidirectional light scattering LED and a manufacturing method thereof are disclosed. A metal oxide is irregular disposed over a second semiconductor layer and then is removed by etching. Part of the second semiconductor layer, part of a light-emitting layer or part of the first semiconductor layer is also removed so as to form a scattering layer. A transparent conductive layer is arranged over the second semiconductor layer while further a second electrode is disposed over the transparent conductive layer. A first electrode is installed on the scattering layer. Thus light output from the LED is scattered in multi-directions.

Abstract: An LED includes a substrate, a first type doping semiconductor layer, a first electrode, a light emitting layer, a second type doping semiconductor layer, a second electrode, a first dielectric layer and a first conductive plug. The first type doping semiconductor layer is formed on the substrate, and the light emitting layer, the second type doping semiconductor layer and the second electrode are formed on a portion of the first type doping semiconductor layer in sequence. The first dielectric layer is formed on another portion of the first type doping semiconductor layer where is not covered by the light emitting layer. The first electrode formed on the first dielectric layer is electrically connected with the first type doping semiconductor layer through the first conductive plug formed in the first dielectric layer. Furthermore, the second electrode is electrically connected with the second type doping semiconductor layer.

Abstract: A structure for integrating LED circuit onto a heat-dissipation substrate is disclosed. At least an electronic component and a LED chip are integrated on a heat-dissipation substrate. The electronic component can be a passive component, a drive chip, an electrostatic discharge protection device, or a sensing component. Therefore, both wire-bonding area of the LED chip and the series resistance of wires are reduced while the heat dissipation efficiency is enhanced.
