  • Patent number: 7473571
    Abstract: There is provided a method for manufacturing a vertically structured LED capable of performing a chip separation process with ease. In the method, a light-emitting structure is formed on a growth substrate having a plurality of device regions and at least one device isolation region, wherein the light-emitting structure has an n-type clad layer, an active layer and a p-type clad layer which are disposed on the growth substrate in sequence. A p-electrode is formed on the light-emitting structure. Thereafter, a first plating layer is formed on the p-electrode such that it connects the plurality of device isolation regions. A pattern of a second plating layer is formed on the first plating layer of the device region. The growth substrate is removed, and an n-electrode is then formed on the n-type clad layer.
