SiC Via Hole & Trench Dry Etching Process (ICP-RIE) - …
Silicon Carbide (SiC) is a compound semiconductor material. While there are some types of crystalline structures including 3C-SiC, 6H-SiC and 4H-SiC, it is considered that 4H-SiC is the most promising material as a substrate of power devices. 4H-SiC has a wide band gap, a high breakdown field and a high thermal conductivity compared to silicon.
