Wolfspeed announces commercial launch of 200mm silicon carbide wafers
Wolfspeed Inc of Durham, NC, USA — which makes silicon carbide (SiC) materials and power semiconductor devices — has announced the commercial launch of its 200mm SiC materials products, marking a milestone in its mission to accelerate the industry’s transition from silicon to silicon carbide. After initially offering 200mm SiC to select customers, the firm says that the positive response and benefits warranted a commercial release to the market.
Wolfspeed is also offering 200mm SiC epitaxy for immediate qualification which, when paired with its 200mm bare wafers, delivers what is claimed to be breakthrough scalability and improved quality, enabling the next generation of high-performance power devices.
“Wolfspeed’s 200mm SiC wafers are more than an expansion of wafer diameter – it represents a materials innovation that empowers our customers to accelerate their device roadmaps with confidence,” says Dr Cengiz Balkas, chief business officer. “By delivering quality at scale, Wolfspeed is enabling power electronics manufacturers to meet growing demand for higher-performing, more efficient silicon carbide solutions.”
The improved parametric specifications of the 200mm SiC bare wafers at 350µm thickness and what is claimed to be enhanced, industry-leading doping and thickness uniformity of the 200mm epitaxy enables device makers to improve MOSFET yields, accelerate time-to-market, and deliver more competitive solutions across automotive, renewable energy, industrial, and other high-growth applications, says Wolfspeed. These product and performance advancements for 200mm SiC can also be applied to continuous learnings for 150mm SiC materials products, the firm adds.
“This advancement reflects Wolfspeed’s long-standing commitment to pushing the boundaries of silicon carbide materials technology,” says Balkas. “This launch demonstrates our ability to anticipate customer needs, scale with demand, and deliver the materials foundation that makes the future of more efficient power conversion possible.”
