August 5, 2010... IQE of Cardiff, UK, a supplier of epitaxial wafer products and wafer services announced that NanoGaN Limited (“NanoGaN”), its wholly owned subsidiary, has been granted two separate patents in relation to its nanocolumn technology. According to IQE, NanoGaN's proprietary nanocolumn technology relates to producing high quality, free-standing gallium nitride substrates, which can be used for the production of advanced blue and green lasers and LEDs.

IQE notes that the production of advanced blue and green semiconductor lasers and ultra high brightness LEDs requires stable, high quality substrates with minimal crystalline defects such as threading dislocations to increase yield and therefore reduce manufacturing costs. Of the two awarded patents, one is a Japanese patent, and the other is a UK patent.
