HistoryEdit

 
Cree's high-power LEDs, XLamp 7090 XR-E Q4
 
A Cree 9.5 watt 800 lumen dimmable lamp bulb, with 2700 K color temperature, introduced in March 2013

Cree was founded in July 1987 in Durham, North Carolina. Five of the six founders – Thomas Coleman, John Edmond, Eric Hunter, John Palmour and Calvin Carter – are graduates of North Carolina State University.[3]

In 1983, the founders – one a research assistant professor and the others student researchers – were seeking ways to leverage the properties of silicon carbide to enable semiconductors to operate at higher operating temperatures and power levels.[3] They also knew silicon carbide could serve as the diode in light-emitting diode (LED) lighting, a light source first demonstrated in 1907 with an electrically-charged diode of SiC.

The research team devised a way to grow silicon crystals in the laboratory, and in 1987 founded a company, Cree Research, Inc., to produce SiC and exploit its usage commercially in both semiconductors and lighting. The founders raised money to establish office and laboratory facilities and entered a period of steady technological advancements.[3]

In 1989, the company introduced the world's first blue LED, which enabled the development of large, full-color video screens and billboards.[3]

In 1991, Cree released the world's first commercial silicon carbide wafer.[3]

In 1993, Cree launched an initial public offering.

In 1999, the company name was changed from Cree Research to Cree, Inc.[4]

In 2011 Cree acquired Ruud Lighting, a national firm experienced in the use of LED for outdoor lighting. This expanded Cree sales channels and led to a new generation of lighting-class LED components.[5]

In 2012 Cree announced the XLamp XT-E, which was claimed to deliver twice as much light for the same price as older LEDs.[6]

In 2013, Cree's first consumer products, two household LED bulbs qualified for Energy Star rating by the United States Environmental Protection Agency.[7]

In July 2016, German chip maker Infineon Technologies AG said it agreed to buy Cree's Wolfspeed business unit (RF and power electronics devices) for $850 million in cash.[8] However, the deal was called off in February 2017 after the companies were unable to resolve regulators’ national security concerns.[9]

In March 2018, Cree announced the acquisition of Infineon Technologies AG's RF Power Business for €345 Million.[10]
