US Patent 7102173 Nitride semiconductor device and method of manufacturing the same

Provided are a nitride semiconductor device and method of manufacturing the same. In the method, semiconductor nanorods are vertically grown on a substrate, and then a nitride semiconductor thin film is deposited on the substrate having the semiconductor nanorods. Accordingly, a high-quality nitride semiconductor thin film can be deposited on a variety of inexpensive, large-sized substrates. Also, because the nitride semiconductor thin film containing the semiconductor nanorods can easily emit light through openings between the nanorods, internal scattering can be greatly reduced. Thus, the nitride semiconductor thin film can be usefully employed in optical devices such as light emitting diodes and electronic devices.
