摘要： 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.

摘要： 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.

摘要： A light-emitting gallium nitride-based III-V group compound semiconductor device and a manufacturing method thereof are disclosed. The light emitting device includes a substrate, a n-type semiconductor layer over the substrate, an active layer over the n-type semiconductor layer, a p-type semiconductor layer over the active layer, a conductive layer over the p-type semiconductor layer, a first electrode disposed on the conductive layer and a second electrode arranged on exposed part of the n-type semiconductor layer. A resistant reflective layer or a contact window is disposed on the p-type semiconductor layer, corresponding to the first electrode so that current passes beside the resistant reflective layer or by the contact window to the active layer for generating light. When the light is transmitted to the conductive layer for being emitted, it is not absorbed or shielded by the first electrode. Thus the current is distributed efficiently over the conductive layer. Therefore, both LED brightness and efficiency are improved. Moreover, adhesion between the conductive layer and the p-type semiconductor layer is improved so that metal peel-off problem during manufacturing processes can be improved.
