  • Cree Inc. NASDAQ: CREE is a Durham, North Carolina based, American corporation which manufactures semiconductor materials and devices. CREE generated $0.37 continuing earnings per share in 2008, and currently enjoys one of the highest trading multiples (highest P/E) on the Nasdaq stock exchange. It was formed in 1987 by researchers from North Carolina State University. Materials products include silicon, silicon carbide and gallium nitride. Device products include light-emitting diodes (LEDs) made from their materials for a variety of uses, as well as power supply chips, motor controllers and microwave radios. The wide band gap semiconductors are suitable for high voltage or high power or high temperature operation. SiC is used for high power electronics, largely due to having a very high thermal conductivity. Two directors of Cree are John Palmour and Chuck Swoboda. Some operations are now located in Hong Kong. The company's silicon fabrication line in Sunnyvale, California is closed, and the company is now focusing on wide band-gap technologies. The company produced a prototype White LED that can produce 161 lumens per watt while drawing 350 mA of current, nearly 10 times what an incandescent (normal) light bulb can produce. As of March 2009, the most efficient white Cree LEDs commercially available, such as the XLamp XR-E R2, achieve 100 lumens per watt. Based on more than 20,000h of continuous testing, Cree estimates that XR-E LEDs will lose 30% of their brightness over a usage period of 50,000h (barring overheating). Cree's competitors include Nichia Corporation, Osram Opto Semiconductors, Philips Lumileds Lighting Company and GE Lighting (Vio). Cree is also facing increasing competition from low cost Taiwanese LED manufacturers such as Epistar and Everlight.
