Is it reliable to grow silicon carbide wafers on a silicon substrate?
Silicon carbide (SiC), as the star material of third-generation semiconductors, is widely used in scenarios such as electric vehicles, photovoltaics, 5G, and high-voltage power grids due to its wide bandgap, high voltage resistance, and high thermal conductivity. But the high cost has always been the "ceiling" for SiC commercial use. So the question is - can SiC be grown on low-cost silicon (Si) substrates like gallium nitride (GaN)? This article takes you to explore the feasibility of growing SiC on Si substrates from three perspectives: technology, economy, and application.
