Wolfspeed has produced a single crystal 300mm silicon carbide wafer, an development that marks the following stage within the improvement of silicon carbide know-how.
The corporate, which holds over 2,300 patents associated to silicon carbide, is getting ready for large-scale manufacturing utilizing the brand new wafer dimension.
Entry deeper trade intelligence
Expertise unmatched readability with a single platform that mixes distinctive information, AI, and human experience.
Wolfspeed’s 300mm platform will help the manufacturing of energy electronics in addition to substrates for optical and radio frequency methods, providing integration potential throughout optical, photonic, thermal, and energy domains.
The transition to 300mm wafers is predicted to fulfill growing demand in sectors reminiscent of AI infrastructure and augmented actuality (AR) or digital actuality (VR) gadgets.
As computing workloads develop and information centre energy necessities proceed to rise, the brand new silicon carbide know-how might assist allow increased voltage energy supply methods and improved thermal administration at wafer scale.
For AR/VR purposes, the fabric properties of silicon carbide reminiscent of thermal conductivity and mechanical energy are thought of appropriate for methods needing compact type elements and environment friendly warmth dissipation.
Past purposes in AI infrastructure and AR/VR platforms, Wolfspeed’s transfer to 300mm wafer manufacturing goals to deal with demand for superior energy gadgets utilized in high-voltage transmission and industrial options.
The change to a bigger diameter substrate is designed to extend manufacturing effectivity and scalability.
The corporate said that its vertically built-in provide chain, overlaying processes from crystal development via superior packaging, will strengthen home semiconductor capabilities.
Wolfspeed chief know-how officer Elif Balkas stated: “Producing a 300mm single crystal silicon carbide wafer is a major know-how achievement and the results of years of centered innovation in crystal development, boule and wafer processing.
“It positions Wolfspeed to help the trade’s most transformative applied sciences, particularly important parts of the AI ecosystem, immersive augmented and digital actuality methods, and different superior energy system purposes.”
In September 2025, Wolfspeed introduced the industrial introduction of its 200mm silicon carbide supplies portfolio.
The launch included each naked wafers and epitaxial merchandise for trade qualification.
In accordance with Wolfspeed, these developments improved system yields with enhanced doping uniformity, thickness consistency and larger scalability.
The data gained from the 200mm platform additionally contributed to its current vary of 150mm silicon carbide merchandise.
