The world-class AIXTRON 8×150 mm G5WW Vapor Phase Epitaxy (VPE) system and decades of semiconductor wisdom.
Why all the intrigue around 150 mm silicon carbide (SiC) wafers? It comes down to power—and the potential to dramatically alter how electricity flows in everything from data centers and solar grids to medical diagnostics and high-speed trains. SiC power devices, including high-performance Schottky diodes and MOSFETs, are already key players in cutting-edge applications. But the challenge confronting the industry has never been technology alone—cost and scalability are king.
Traditional semiconductor wafers, often 100 mm across, face bottlenecks as demand soars. Larger wafers mean more devices per batch, lower manufacturing costs, and wide-reaching adoption. Yet, with silicon carbide’s intrinsic hardness and tendency for microscopic defects, scaling up to the robust 150 mm format is no trivial feat.
Fraunhofer IISB, celebrated for its prowess in material science, brings to the partnership its mastery in defect reduction and advanced characterization techniques, such as room-temperature photoluminescence imaging. This precision ensures that SiC layers grown are flawless—crucial for the reliable performance of high-voltage devices.
AIXTRON, with a global reputation for innovation in deposition equipment, injects the collaboration with the muscle and technical finesse needed for industrial-scale manufacturing. Together, their synergy is not just optimizing processes but redefining what is possible in composite semiconductor production.
The true impact, though, will ripple beyond laboratories and factory floors. AIXTRON and Fraunhofer IISB are paving the way for SiC to leap from niche to norm. Think of computers that waste less power, solar farms that convert energy with razor-sharp efficiency, and a next-gen grid resilient enough to meet tomorrow’s challenges.
As the industry migrates toward 150 mm SiC technology, the promise is clear: lighter, faster, more efficient power electronics. Costs will drop, adoption will soar, and everyday technology—in homes, hospitals, trains, and more—will quietly become smarter, greener, and more reliable.
Key takeaway: Innovation flourishes where expertise converges. The AIXTRON-Fraunhofer alliance is not just advancing wafer size; it is laying the groundwork for a revolution in how we harness and transmit electrical energy, with global benefits poised to touch every facet of modern life.

What Is Silicon Carbide—and Why Does the Wafer Size Matter?
Silicon carbide is a semiconductor material prized for its exceptional thermal conductivity, high breakdown electric field, and immense mechanical hardness. These properties allow SiC-based devices to:
– Operate at higher voltages, frequencies, and temperatures than standard silicon devices
– Deliver superior efficiency (less energy lost as heat)
– Shrink the size of modules, leading to lighter, more compact power systems
Wider wafers—like the new industrial 150 mm format—mean:
– More chips produced in every manufacturing batch
– Dramatically lower costs per device
– Increased scalability and mainstream adoption for automotive, renewable energy, industrial, and consumer tech
