What changed from existing technology?
This study introduces a new method to cut silicon carbide wafers more precisely using a laser and side scoring, which reduces damage and improves the cutting process.
This study is the first to apply femtosecond laser slicing with side scribing to 4H-SiC, addressing the boundary effect that limits conventional laser processing.

What still needs to be solved?
Repeated real-world validation, manufacturability, cost, and long-term stability still require follow-up evidence.
What could change if this succeeds?
This technology could improve the manufacturing of high-power and high-frequency devices by enabling more precise and less damaging slicing of 4H-SiC wafers.
