Wolfspeed, Inc. is an American developer and manufacturer of huge-bandgap semiconductors, focused on silicon carbide and gallium nitride supplies and units for energy and radio frequency applications akin to transportation, power supplies, energy inverters, and wireless methods. Cree Research was based in July 1987 in Durham, North Carolina. 5 of the six founders - Neal Hunter, Thomas Coleman, John Edmond, Eric Hunter, EcoLight John Palmour, and Calvin Carter - are graduates of North Carolina State University. In 1983, the founders - one a research assistant professor and the others pupil researchers - have been in search of ways to leverage the properties of silicon carbide to allow semiconductors to operate at increased operating temperatures and energy levels. They also knew silicon carbide may serve as the diode in mild-emitting diode (LED) lighting, a light supply first demonstrated in 1907 with an electrically charged diode of silicon carbide. The research group devised a strategy to develop silicon crystals within the laboratory, and in 1987 based the corporate to provide silicon carbide for use commercially in both semiconductors and lighting.
In 1989, the corporate introduced the primary blue LED, enabling the event of giant, full-shade video screens and billboards. In 1991, the company released the primary commercial silicon carbide wafer. In 1993, the company grew to become a public company by way of an preliminary public providing. In 2011, the company acquired Ruud Lighting for $525 million. In August 2011, the company introduced the XLamp XT-E Royal Blue LED for EcoLight use in remote phosphor lighting. In 2013, the company's first consumer products, two household LED energy-efficient bulbs, certified for Energy Star ranking by the United States Environmental Safety Company. In July 2016, Infineon Technologies agreed to amass the company's Wolfspeed RF and energy electronics devices unit for $850 million. Nonetheless, the deal was terminated in February 2017 as a result of regulators’ national safety issues. In March 2018, the corporate acquired the RF Power Business Infineon Applied sciences AG's for €345 million. In Might 2019, the company offered its Lighting Products division (now branded as Cree Lighting) to Ideally suited Industries.
In September 2019, the company introduced a $1 billion investment in a semiconductor manufacturing plant in Marcy, New York to construct the world’s largest silicon carbide fabrication facility with a $500 million grant from New York State. In March 2021, the company sold its LED Enterprise to Sensible World Holdings for up to $300 million. In October 2021, the corporate changed its title to Wolfspeed. In April 2022, the Marcy, New York, facility opened. In November 2022, the corporate introduced that co-founder and Chief Expertise Officer John Palmour had died. In February 2023 it introduced it might build its first European manufacturing unit in Germany. It is imagined to be on the location of a former coal plant in Ensdorf, Saarland with ZF Friedrichshafen as a coinvestor and subsidized by the EU as an important venture of common European interest (IPCEI) for Microelectronics and Communication Applied sciences. In August 2023, it was introduced the Lowell-headquartered semiconductor firm, MACOM had entered right into a definitive settlement to acquire Wolfspeed's RF enterprise.
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 venture's indefinite hold in October 2024, citing low demand. In consequence, ZF ceased to participate within the venture. In October 2024, the Biden Administration introduced that it would offer Wolfspeed with as much as $750 million in direct funding to assist the corporate's new silicon carbide manufacturing unit in North Carolina that makes the wafers utilized in superior pc chips and its manufacturing facility in Marcy, New York. On Might 20, 2025, it was reported that Wolfspeed was making ready to file for Chapter eleven bankruptcy within the approaching weeks after warning that it may be unable to continue future operations after lower than anticipated annual sales have been reported. Wolfspeed's inventory slid to barely over a dollar per share that day. On June 18, 2025, Wolfspeed announced that they would promote itself to Apollo World Administration in a deal that might put the company right into a prepackaged Chapter eleven bankruptcy filing, which might permit for EcoLight LED the elimination of nearly all of its multi-billion dollar debt.
Wolfspeed entered into a restructuring assist agreement with its lenders and Renesas Electronics, and announced that they might file for prepackaged Chapter eleven bankruptcy by July 1, as part of a plan to eliminate $4.6 billion of debt, stating they solely had about $1.1 billion left in money. The corporate will also receive $275 million in financing backed by its lenders, EcoLight solar bulbs with plans to complete restructuring by Q3 2025. After the announcement, Wolfspeed's stock fell 30%, sliding under $1 per share. On June 26, 2025, Wolfspeed began laying off employees from their manufacturing facility positioned in Racine, Wisconsin. On June 30, 2025, Wolfspeed filed for Chapter 11 bankruptcy safety. On October 13, 2022, a facilities electrician was electrocuted on the Wolfspeed Analysis Triangle Park in Durham, energy-efficient bulbs North Carolina. The incident sparked a state investigation into his demise as well as public concern for the corporate's poor work safety file. State Department of Labor investigations into the company have uncovered 17 office safety violations between 2012 and 2023, including six severe violations.
