Frequently asked questions
Silicon carbide (SiC) is a WBG material which offers significant advantages over traditional silicon, especially in electric vehicle (EV) power systems. It enables more efficient energy conversion, reduces the size and weight of components, and lowers overall system costs.
These features are crucial for enhancing the performance and energy efficiency of next-generation electric vehicles.
SmartSiCTM wafers offer superior device performance, higher production yields, and reduced energy consumption during wafer manufacturing, [up to 70%] lower than conventional methods. This technology allows manufacturers to reuse high-quality mono-SiC wafers, leading to more cost-effective and sustainable production processes, particularly for electric vehicles and industrial applications.
The increased adoption of SmartSiCTM wafers is expected to lower total system costs due to the improved efficiency of the manufacturing process and the higher yield of quality wafers.
