Bright overhead lights reveal a swirling dance of engineers and researchers within the cleanroom corridors of Erlangen, Germany—home to the Fraunhofer IISB, a world-class center for semiconductor innovation. In a move that signals a shift in the power electronics landscape, Fraunhofer IISB and AIXTRON have joined forces to unlock new dimensions for Silicon Carbide (SiC) epitaxy technology.
Silicon Carbide isn’t new to the scene; this resilient material powers essential components inside computer servers, medical equipment, solar inverters, and the trains that carry commuters home. What’s changing, and changing fast, is the way we build these tiny, powerful devices.
AIXTRON’s cutting-edge G5WW Vapor Phase Epitaxy system, capable of simultaneously processing eight 150 mm SiC wafers, is at the heart of this leap. The system—destined for Fraunhofer IISB’s state-of-the-art laboratories—promises a scale and precision previously out of reach. Here, world-renowned scientists, armed with years of SiC research and advanced defect-detection tools, push the boundaries of what’s possible.
The advantage in size is more than academic. By moving from 100 mm to 150 mm wafers, manufacturers could slash both costs and defects. Larger wafers translate to more devices produced per run—a vital step toward bringing affordable, high-performance power electronics to everyday life.
Researchers have fine-tuned every stage. At Fraunhofer, they deploy specialized techniques, from room-temperature photoluminescence imaging to selective defect etching, ensuring the SiC layers exhibit ultra-low densities of crystalline flaws. This focus on perfection is crucial. Even a single imperfection in a power device, such as a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) or Schottky diode, can mean the difference between failure and flawless function in critical infrastructure.
The collaboration aims not just at prototype demonstration but at real, high-volume manufacturing. Think solar grids humming more efficiently, data centers consuming less energy, and electric trains running smoother—all thanks to the foundational work happening within these laboratory walls.
This partnership sets the course for the next generation of SiC devices, which experts believe will dominate power electronics markets by the end of this decade. The domino effect for consumers will be palpable: sharper declines in energy usage, faster adoption of green-energy tech, and a quieter environmental footprint, all propelled by the silent, steady progress of wafer technology.
As the world races toward higher efficiency and sustainability, collaboration between industry leaders like AIXTRON and research giants such as Fraunhofer IISB demonstrates not just technical prowess, but a shared vision. These titans are forging the building blocks of an electrified future—one silicon carbide layer at a time.
