✅ July 2026: Bosch signed a $225 million U.S. CHIPS Program funding agreement to support its planned up to $2 billion transformation of the Roseville, California facility into a silicon carbide semiconductor manufacturing site. Bosch has also begun sample production and is targeting its first commercial SiC chips on 200 mm wafers in 2026, adding domestic capacity for automotive and other power applications.

✅ August 2026: Wolfspeed and LITEON qualified Wolfspeed's SiC MOSFETs for LITEON's 800 VDC power sidecar and compute-rack PSU platforms aimed at hyperscale AI data centers. The partnership is notable because it links Wolfspeed's 200 mm SiC manufacturing platform directly with emerging high-voltage data-center power architectures rather than limiting SiC demand to EV applications.

✅ September 2026: SiC moved further into high-voltage AI infrastructure, with Infineon extending its collaboration with SolarEdge on solid-state circuit breakers for 800 VDC AI and hyperscale data centers. Infineon is supplying SiC JFET technology for ultra-fast DC fault isolation, addressing a specific protection challenge created by higher-voltage data-center architectures.

Recent Key Developments - Japan & Asia-Pacific
✅ September 2026: Toshiba Electronic Devices & Storage launched a 3,300 V, 800 A dual SiC MOSFET module for railway traction, renewable-energy generation, power-conversion and industrial motor-control equipment. The new module expands SiC deployment into higher-power industrial systems where surge capability and reliability are critical.

✅ September 2026: ROHM Semiconductor announced that its SiC chips are being used in BMW's Neue Klasse electric-vehicle platform, including the automaker's Gen 6 electric-vehicle architecture. The deployment places ROHM SiC technology directly into a new-generation vehicle powertrain rather than remaining at the prototype or evaluation stage.

✅ September 2026: Toshiba reported a new trench-gate SiC MOSFET gate-oxide process that reduced threshold-voltage drift by approximately 50% compared with commercially available trench-gate SiC MOSFETs. The work targets a known long-term reliability issue and is being presented at ICSCRM 2026 in Yokohama, with potential applications spanning EVs, renewable-energy systems and data-center power supplies.

Recent Key Developments - Product & Technology Innovation
✅ September 2026: 200 mm Premium SiC Substrates: Wolfspeed introduced commercial availability of a premium 200 mm n-type SiC substrate designed to reduce defects and improve wafer-shape stability. The move highlights wafer quality and yield as increasingly important differentiators as SiC devices move toward larger die sizes and higher voltages.

✅ August 2026: 300 mm SiC Thermal Platforms: Coherent began customer sampling of 300 mm high-thermal-conductivity SiC substrates for AI and high-performance computing applications. The company is positioning SiC not only as a power-switching material but also as a thermal-management material for high-power AI semiconductor packaging.

✅ September 2026: High-Voltage SiC Reliability: Toshiba's latest gate-oxide treatment technology addresses threshold-voltage drift under prolonged electrical stress, cutting the measured drift to roughly half that of commercial trench-gate SiC MOSFETs. This points to reliability engineering becoming as important as reducing conduction and switching losses as SiC devices move into higher-voltage, long-duty-cycle applications.
