Cree Inc. American manufacturer of high-power semiconductor LEDs and other electronic components located in Durham North Carolina.
Cree was founded in 1981 by researchers from the University of North Carolina NCSU engaged in the study of silicon carbide with 19832. Became public in 1993 when there were about 20 people.3 Originally produced electronic circuitry and light-emitting devices based on gallium nitride red and green светодиоды3 engaged госконтрактами5.
The company has engaged in the cultivation of crystals of silicon carbide.1 According to the magazine Expert in the development of this technology was attended by Russian scientists from LETI.1
In 1989, started commercial production of plates of silicon carbide with a diameter of 25 millimeters.1 In early 2000, was made for 100 mm crystals more than 250 plants.1
The first integrated circuit on the basis of silicon carbide the company introduced in 1996 but was unable to establish serial production.6
From the middle of the first decade of the 2000s, actively engaged in the production of light-emitting devices based on carbide кремния5.
In 2005, Cree opened a subsidiary, Cree Asia-Pacific in Hong Kong.18
In March 2001, Cree bought bright LED manufacturer Cotco Luminant Device in Hong Kong for $200 million dollars.9
In 2009, Cree bought the first plant located outside the United States. It is in Huizhou Guangdong Province China.10 Then Cree has announced the expansion of production at its plant in Derema.11
As of 2012, Cree delivers about 85 % of global demand for silicon carbide.1
