Cree was founded in July 1987 in Durham, North Carolina. Five of the six founders – Neal Hunter, Thomas Coleman, John Edmond, Eric Hunter, John Palmour and Calvin Carter – are graduates of North Carolina State University.[4] The company was known for lighting-class LEDs, lighting products, and products for power and radio frequency (RF) applications. Most of its products are based on silicon carbide (SiC), a mineral compound which early Cree researchers successfully synthesized in a laboratory.
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.[4] 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.[4]
In 1989, the company introduced the world's first blue LED, which enabled the development of large, full-color video screens and billboards.[4]
In 1991, Cree released the world's first commercial silicon carbide wafer.[4]
In 1993, Cree launched an initial public offering.
In 1999, the company name was changed from Cree Research to Cree, Inc.[5]
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.[6]
In 2012 Cree announced the XLamp XT-E, which was claimed to deliver twice as much light for the same price as older LEDs.[7]
In 2013, Cree's first consumer products, two household LED bulbs qualified for Energy Star rating by the United States Environmental Protection Agency.[8]
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.[9] However, the deal was called off in February 2017 after the companies were unable to resolve regulators’ national security concerns.[10]
In March 2018, Cree announced the acquisition of Infineon Technologies AG's RF Power Business for €345 million.[11]
In May 2019, Cree Inc. closed on the sale of their Cree Lighting Products division to Ideal Industries Inc.[12]
In October 2020, Cree Inc. announced the sale of their LED Business to for up to $300 million.[13] This led to a January 2021 announcement of a name change to Wolfspeed, reflecting its change in emphasis from LED lighting to semiconductors.[14]
