At the epicenter of this evolution stands the collaboration with AIXTRON, a world-renowned maker of vapor phase epitaxy (VPE) equipment. Their new mission: to perfect the art of crafting 150 mm Silicon Carbide (SiC) wafers using AIXTRON’s cutting-edge G5WW reactor—a system engineered for precision and scalability. This isn’t just incremental progress; it’s a leap in material science poised to ripple through the global power electronics landscape.
Why Silicon Carbide Now?
Traditional silicon chips have long powered our devices, but SiC introduces a tougher, more efficient alternative. Its crystalline grit withstands high voltages and extreme temperatures, making it an ideal foundation for next-generation Schottky diodes and MOSFETs—semiconductor devices crucial in applications requiring rapid, reliable power switching.
From data centers and televisions to medical equipment and commuter trains, SiC devices have already found their way into daily life. Yet, wider adoption hinges on cracking two challenges: increasing wafer size and slashing production costs. Here, scaling up from 100 mm to 150 mm wafers means more chips per batch, better economy of scale, and lower prices—opening the door to an energy revolution everywhere these chips operate.
Inside the Lab: Precision at Atomic Scale
Fraunhofer IISB delivers mastery in growing defect-free SiC layers—foundational for high-voltage device reliability. Using advanced photoluminescence imaging and special chemical etching, researchers interrogate the very soul of these crystals, mapping imperfections invisible to the naked eye. The result: prototype SiC wafers with dauntingly low defect rates, tailored to meet rigorous industry standards.
Installed in IISB’s pristine cleanrooms, the AIXTRON Planetary Reactor now becomes a testbed not just for experimentation, but for process optimization on a scale suitable for mass production. The aim is nothing less than a blueprint for high-yield, industry-grade SiC semiconductor manufacturing.
The Stakes: Speed, Sustainability, and Scale
Power electronics are fast becoming the silent engine of our electrified world. SiC chips slash energy losses, shrink device sizes, and enable greener solutions across industries. Efficient solar inverters propel renewable energy; resilient server power supplies hum behind cloud computing; ultralight, quick-charging trains edge us closer to carbon-neutral mobility.
This German initiative is more than a technical upgrade. It’s a pivotal step toward sustainable technology—the migration from 100 mm to 150 mm SiC wafers promises to reshape supply chains, lower consumer costs, and bolster Europe’s place in the competitive semiconductor arena. Companies across the globe now look to this partnership as a playbook for their own transitions, eager to harness the high efficiency and robustness SiC uniquely delivers.
Key Takeaway: The alliance between AIXTRON and Fraunhofer IISB aims to supercharge the world’s transition to more powerful, energy-efficient electronics by ushering in a new era of scalable, cost-effective Silicon Carbide technology. As their innovation pulses outward from Erlangen, the promise is clear: Our future devices won’t just be faster—they’ll be cleaner, smarter, and built to endure.
