The monochromatic or multicolored high performance by the growth on the baseplate which patterning is done the light-emitting diode (LED)

摘要

The monochromatic or multicolored light-emitting diode (LED) which possesses high extraction efficiency, the patterning of one or more which is accumulated on top of buffer layer and the buffer layer which were formed on the baseplate and the baseplate layer and the patterning which are done is formed from the active layer of one or more which was formed on the layer which is done or between layer. As for the above-mentioned light-emitting diode, for example, it is something due to cross direction epitaxial growth (LEO), the luminous kind (for example, quantum well) of one or more is included. The layer which patterning is done being done and patterning it has with the material which the hole inside the mask (being constituted from the insulating material or the semiconducting material or the metallic materials,) and the mask which it is perforated or are penetrated, or fills up. Originating in the contrast of refractive index of active layer, function it does the layer which patterning is done, as optical shutting in layer, at the same time/or it originates in the change of refractive index with the material which fills up the hole inside the mask and the above-mentioned mask and functioning it does as a pad diffraction grating.
