+<br>Wolfspeed, Inc. is an American developer and manufacturer of wide-bandgap semiconductors, centered on silicon carbide and gallium nitride materials and devices for power and radio frequency applications resembling transportation, power provides, power inverters, and wireless techniques. Cree Analysis was founded in July 1987 in Durham, North Carolina. 5 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 - have been seeking ways to leverage the properties of silicon carbide to allow semiconductors to function at larger working temperatures and power ranges. In addition they knew silicon carbide could serve because the diode in mild-emitting diode (LED) lighting, a light source first demonstrated in 1907 with an electrically charged diode of silicon carbide. The research workforce devised a solution to develop silicon crystals within the laboratory, and in 1987 founded the corporate to produce silicon carbide for use commercially in both semiconductors and lighting.<br>
+
+<br>In 1989, the company launched the first blue LED, enabling the development of massive, full-shade video screens and billboards. In 1991, the company launched the primary business silicon carbide wafer. In 1993, the company became a public company through an preliminary public offering. In 2011, the company acquired Ruud Lighting for $525 million. In August 2011, the corporate announced the XLamp XT-E Royal Blue LED for use in remote phosphor [lighting](https://dict.leo.org/?search=lighting). In 2013, the corporate's first consumer products, two household LED bulbs, qualified for Power Star ranking by the United States Environmental Protection Company. In July 2016, Infineon Applied sciences agreed to acquire the corporate's Wolfspeed RF and  [EcoLight](https://asteroidsathome.net/boinc/view_profile.php?userid=860666) energy electronics devices unit for $850 million. However, the deal was terminated in February 2017 resulting from regulators’ national security issues. In March 2018, the corporate acquired the RF Energy Enterprise Infineon Technologies AG's for €345 million. In Could 2019, the corporate sold its Lighting Merchandise division (now [branded](https://www.bbc.co.uk/search/?q=branded) as Cree Lighting) to Perfect Industries.<br>
+
+<br>In September 2019, the corporate introduced a $1 billion funding 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 offered its LED Business to Smart International Holdings for  [EcoLight brand](http://ec2-44-211-138-212.compute-1.amazonaws.com:8080/index.php/All_LED_Bulb_Sorts_And_Shapes) up to $300 million. In October 2021, the company modified its name to Wolfspeed. In April 2022, the Marcy, New York, 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 will build its first European manufacturing unit in Germany. It's alleged to be on the positioning of a former coal plant in Ensdorf, Saarland with ZF Friedrichshafen as a coinvestor  EcoLight and subsidized by the EU as an important project of widespread European curiosity (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 amass Wolfspeed's RF enterprise.<br>
+
+<br>In June 2024, Wolfspeed has delayed its $three billion semiconductor plant in Germany to mid-2025, reflecting the EU's challenges in boosting local chip manufacturing. Wolfspeed announced the venture's indefinite hold in October 2024, citing low demand. Because of this, ZF ceased to participate within the venture. In October 2024, the Biden Administration announced that it would offer Wolfspeed with as much as $750 million in direct funding to help the company's new silicon carbide manufacturing unit in North Carolina that makes the wafers used in advanced pc chips and 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 continue future operations after decrease than expected annual sales have been reported. Wolfspeed's inventory slid to barely over a dollar per share that day. On June 18, 2025, Wolfspeed introduced that they'd promote itself to Apollo Global Administration in a deal that may put the corporate into a prepackaged Chapter 11 bankruptcy filing, which might enable for the elimination of the majority of its multi-billion greenback debt.<br>
+
+<br>Wolfspeed entered right into a restructuring assist settlement with its lenders and Renesas Electronics, and introduced that they'd 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 solely had about $1.1 billion left in cash. The corporate can even obtain $275 million in financing backed by its lenders, with plans to complete restructuring by Q3 2025. After the announcement, Wolfspeed's inventory fell 30%, sliding beneath $1 per share. On June 26, 2025, Wolfspeed started laying off staff from their manufacturing facility situated in Racine, Wisconsin. On June 30, 2025, Wolfspeed filed for Chapter eleven bankruptcy protection. On October 13, 2022, a facilities electrician was electrocuted at the Wolfspeed Analysis Triangle Park in Durham, North Carolina. The incident sparked a state investigation into his death in addition to public concern for the corporate's poor work safety document. State Department of Labor investigations into the corporate have uncovered 17 workplace safety violations between 2012 and 2023, together with six critical violations.<br>
