These wafers are created through a process called epitaxy, which involves growing a single-crystal layer on top of a substrate wafer. The resulting epitaxial layer possesses the same crystallographic orientation as the substrate, ensuring high-quality and uniform material properties. https://aishnavicmi.livepositively.com/the-growing-role-of-sic-and-gan-epitaxial-wafers-in-electric-vehicles/new=1
