DIGITIMES Insight: SiC substrate capacity expansion continued; 6-inch substrate prices expected to rebound in 2027

DIGITIMES has observed that demand for silicon carbide (SiC) power devices has climbed rapidly in recent years as the EV market expands, triggering a massive wave of capacity expansion among SiC substrate makers. However, as SiC substrate capacity continued to surge, actual demand for SiC power devices from the EV sector fell short of expectations. This imbalance triggered a collapse in SiC substrate prices starting in 2024, extending the downward trend through 2026.
