Wolfspeed hires Matthias Buchner as senior VP of global sales & chief marketing officer
Wolfspeed Inc of Durham, NC, USA — which makes silicon carbide (SiC) materials and power semiconductor devices — has appointed Matthias Buchner as senior VP of global sales & chief marketing officer, effective 1 December. He will report directly to chief executive officer Robert Feurle.
Buchner will lead Wolfspeed’s global sales and marketing organizations, with a focus on leveraging the firm’s silicon carbide (SiC) devices, produced on its vertically integrated 200mm manufacturing platform.
His appointment comes as Wolfspeed sharpens its focus on product innovation and device production — reflecting its scaling of silicon carbide manufacturing to meet global demand. It also supports Wolfspeed’s strategy to broaden its customer base across diverse, high-growth markets including automotive, renewable energy, industrial power systems, and AI-driven data infrastructure.
Buchner joins Wolfspeed from Infineon Technologies AG, where he was most recently senior VP of marketing for the Power & Sensor Systems Division, responsible for strategic communication, partnership management, distribution marketing, digital marketing and marketing operations for a $3bn+ business. Over his more than 20-year career, he has held senior leadership positions at Infineon, Micron Technology, and other technology firms, with experience in both silicon and silicon carbide power solutions, business development, and global customer engagement.
“Attracting a world-class sales and marketing executive like Matthias at this critical juncture underscores Wolfspeed’s commitment to capturing the immense opportunities ahead,” says president & CEO Robert Feurle. “His global leadership experience across silicon and silicon carbide technologies — spanning automotive, industrial, and other competitive markets — will be instrumental as we strengthen our customer relationships and expand into rapidly growing segments such as AI data centers, renewable energy, grid infrastructure, and aerospace & defense,” he adds. “With Matthias joining our team, Wolfspeed is exceptionally well positioned to translate our vertically integrated silicon carbide platform into sustainable, profitable growth.”
Buchner’s appointment strengthens Wolfspeed’s leadership team as it continues to focus on improving operational execution, scaling manufacturing capacity, and expanding its position in silicon carbide technology.
“Wolfspeed’s deep domain expertise in producing silicon carbide devices sets the industry standard for performance and quality in today’s competitive landscape,” comments Buchner. “Building strong, trusting relationships with our customers will be a key focus for me immediately out of the gate, as we work together to accelerate the global transition from silicon-based to silicon carbide-based technologies.”
Recent strategic and operational progress
Wolfspeed recently completed a strategic refinancing initiative that has strengthened its balance sheet, positioing it for sustained, profitable growth. In conjunction, the firm has rationalized its global production footprint to align with demand and enhance capital efficiency. This includes the planned closure of its 150mm device fabrication facility on the Durham campus by the end of 2025, as well as the decision to discontinue development of a proposed device fab in Saarland, Germany. These actions streamline Wolfspeed’s manufacturing operations around its 200mm silicon carbide platform and support its long-term focus on operational excellence, productivity and profitability.
Wolfspeed has invested in next-generation facilities in the USA, including its advanced materials factory in North Carolina, device fabrication operations in New York, and device packaging facility in Arkansas. Together, these sites provide ample capacity and flexibility to serve customer needs efficiently and reliably from a consolidated US footprint, it is reckoned.
