Wolfspeed, Inc. is an American developer and manufacturer of large-bandgap semiconductors, centered on silicon carbide and gallium nitride materials and gadgets for power and radio frequency applications similar to transportation, reduce energy consumption supplies, power inverters, and EcoLight dimmable wireless programs. Cree Analysis 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 College. In 1983, the founders - one a research assistant professor and the others pupil researchers - had been searching for methods to leverage the properties of silicon carbide to enable semiconductors to function at increased operating temperatures and power ranges. In addition they knew silicon carbide could serve as the diode in mild-emitting diode (LED) lighting, a gentle source first demonstrated in 1907 with an electrically charged diode of silicon carbide. The analysis staff devised a way to grow silicon crystals in the laboratory, and in 1987 based the company to supply silicon carbide for use commercially in each semiconductors and lighting.



In 1989, the corporate introduced the primary blue LED, enabling the development of giant, full-colour video screens and billboards. In 1991, the corporate launched the primary commercial silicon carbide wafer. In 1993, the company became a public firm through an preliminary public offering. In 2011, the company acquired Ruud Lighting for $525 million. In August 2011, the corporate introduced the XLamp XT-E Royal Blue LED to be used in remote phosphor lighting. In 2013, the company's first consumer merchandise, two family LED bulbs, certified for Vitality Star rating by the United States Environmental Safety Company. In July 2016, Infineon Applied sciences agreed to amass the corporate's Wolfspeed RF and energy electronics devices unit for $850 million. However, the deal was terminated in February 2017 as a result of regulators’ nationwide security issues. In March 2018, the company acquired the RF Energy Business Infineon Technologies AG's for EcoLight lighting €345 million. In Might 2019, the company bought its Lighting Merchandise division (now branded as Cree Lighting) to Splendid Industries.



In September 2019, reduce energy consumption the corporate introduced a $1 billion funding in a semiconductor manufacturing plant in Marcy, New York to build the world’s largest silicon carbide fabrication facility with a $500 million grant from New York State. In March 2021, the corporate sold its LED Business to Sensible World Holdings for up to $300 million. In October 2021, EcoLight the corporate changed its title to Wolfspeed. In April 2022, the Marcy, New York, EcoLight energy facility opened. In November 2022, the corporate announced that co-founder and Chief Technology Officer John Palmour had died. In February 2023 it announced it could build its first European manufacturing unit in Germany. It's supposed to be on the site of a former coal plant in Ensdorf, Saarland with ZF Friedrichshafen as a coinvestor and subsidized by the EU as an necessary project of frequent European curiosity (IPCEI) for Microelectronics and Communication Technologies. In August 2023, it was introduced the Lowell-headquartered semiconductor firm, reduce energy consumption MACOM had entered right into a definitive settlement to accumulate Wolfspeed's RF business.



In June 2024, Wolfspeed has delayed its $three billion semiconductor plant in Germany to mid-2025, reflecting the EU's challenges in boosting native chip manufacturing. Wolfspeed introduced the challenge's indefinite hold in October 2024, citing low demand. In consequence, ZF ceased to take part within the mission. In October 2024, the Biden Administration introduced that it would supply Wolfspeed with as much as $750 million in direct funding to support the corporate's new silicon carbide manufacturing unit in North Carolina that makes the wafers used in advanced pc chips and reduce energy consumption its manufacturing unit in Marcy, New York. On May 20, 2025, it was reported that Wolfspeed was making ready to file for Chapter eleven bankruptcy inside the approaching weeks after warning that it may be unable to proceed future operations after decrease than expected annual gross sales were reported. Wolfspeed's stock slid to barely over a dollar per share that day. On June 18, 2025, Wolfspeed introduced that they'd sell itself to Apollo International Administration in a deal that might put the company into a prepackaged Chapter eleven bankruptcy filing, which might enable for the elimination of the vast majority of its multi-billion dollar debt.



Wolfspeed entered into a restructuring help settlement with its lenders and Renesas Electronics, and reduce energy consumption introduced that they would file for prepackaged Chapter 11 bankruptcy by July 1, as part of a plan to get rid of $4.6 billion of debt, stating they only had about $1.1 billion left in money. The corporate may even receive $275 million in financing backed by its lenders, with plans to finish restructuring by Q3 2025. After the announcement, Wolfspeed's stock fell 30%, sliding below $1 per share. On June 26, 2025, Wolfspeed started laying off employees from their manufacturing facility located in Racine, EcoLight Wisconsin. On June 30, 2025, Wolfspeed filed for Chapter 11 bankruptcy safety. On October 13, 2022, a facilities electrician was electrocuted on the Wolfspeed Research Triangle Park in Durham, North Carolina. The incident sparked a state investigation into his loss of life in addition to public concern for the company's poor reduce energy consumption work security file. State Division of Labor investigations into the corporate have uncovered 17 workplace safety violations between 2012 and 2023, together with six serious violations.
