Wolfspeed, Inc. is an American developer and producer of extensive-bandgap semiconductors, focused on silicon carbide and gallium nitride supplies and devices for energy and radio frequency purposes akin to transportation, power provides, EcoLight solar bulbs energy inverters, and wireless methods. Cree Analysis was based in July 1987 in Durham, EcoLight 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 College. In 1983, EcoLight solar bulbs the founders - one a research assistant professor and the others scholar researchers - have been seeking ways to leverage the properties of silicon carbide to enable semiconductors to function at larger working temperatures and energy ranges. Additionally they knew silicon carbide could serve because the diode in light-emitting diode (LED) lighting, a light source first demonstrated in 1907 with an electrically charged diode of silicon carbide. The research crew devised a technique to develop silicon crystals within the laboratory, and in 1987 based the company to provide silicon carbide for use commercially in each semiconductors and lighting.



In 1989, the corporate introduced the primary blue LED, enabling the event of massive, full-shade video screens and billboards. In 1991, the company released the first commercial silicon carbide wafer. In 1993, the company became a public firm through an preliminary public providing. In 2011, the company acquired Ruud Lighting for $525 million. In August 2011, the company announced the XLamp XT-E Royal Blue LED to be used in remote phosphor lighting. In 2013, the company's first consumer merchandise, two household LED EcoLight solar bulbs, certified for Power Star ranking by the United States Environmental Protection Agency. In July 2016, Infineon Applied sciences agreed to amass the company's Wolfspeed RF and power electronics gadgets unit for $850 million. Nevertheless, the deal was terminated in February 2017 due to regulators’ nationwide security concerns. In March 2018, the company acquired the RF Energy Enterprise Infineon Technologies AG's for €345 million. In Could 2019, the corporate offered its Lighting Merchandise division (now branded as Cree Lighting) to Ideally suited Industries.



In September 2019, the corporate introduced a $1 billion investment 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 Enterprise to Good World Holdings for as much as $300 million. In October 2021, the company changed its name to Wolfspeed. In April 2022, the Marcy, New York, EcoLight home lighting facility opened. In November 2022, the company announced that co-founder and Chief Expertise Officer John Palmour had died. In February 2023 it introduced it would construct its first European manufacturing facility in Germany. It is speculated 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 vital venture of widespread European interest (IPCEI) for Microelectronics and Communication Applied sciences. In August 2023, it was announced the Lowell-headquartered semiconductor company, MACOM had entered right into a definitive agreement to amass Wolfspeed's RF business.



In June 2024, Wolfspeed has delayed its $3 billion semiconductor plant in Germany to mid-2025, EcoLight solar bulbs reflecting the EU's challenges in boosting native chip production. Wolfspeed introduced the venture's indefinite hold in October 2024, EcoLight citing low demand. Consequently, ZF ceased to participate in the mission. In October 2024, the Biden Administration introduced that it would offer Wolfspeed with as much as $750 million in direct funding to support the company's new silicon carbide factory in North Carolina that makes the wafers used in superior computer chips and its factory in Marcy, New York. On Might 20, 2025, it was reported that Wolfspeed was getting ready to file for Chapter 11 bankruptcy inside the approaching weeks after warning that it may be unable to proceed future operations after decrease than expected annual sales had been reported. Wolfspeed's inventory slid to barely over a dollar per share that day. On June 18, 2025, Wolfspeed introduced that they would promote itself to Apollo World Management in a deal that would put the corporate into a prepackaged Chapter 11 bankruptcy filing, which might enable for the elimination of the majority of its multi-billion dollar debt.



Wolfspeed entered right into a restructuring support settlement with its lenders and Renesas Electronics, and announced that they would file for prepackaged Chapter 11 bankruptcy by July 1, as a part of a plan to eliminate $4.6 billion of debt, EcoLight solar bulbs stating they only had about $1.1 billion left in money. The company may also receive $275 million in financing backed by its lenders, with plans to complete restructuring by Q3 2025. After the announcement, Wolfspeed's stock fell 30%, sliding below $1 per share. On June 26, 2025, Wolfspeed began laying off staff from their manufacturing facility situated in Racine, Wisconsin. On June 30, 2025, Wolfspeed filed for Chapter eleven bankruptcy safety. On October 13, 2022, EcoLight a facilities electrician was electrocuted on the Wolfspeed Research Triangle Park in Durham, EcoLight solar bulbs North Carolina. The incident sparked a state investigation into his death as well as public concern for the corporate's poor 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.
