질문과대답:
What is the main advantage of 4H-SiC compared with 6H-SiC?
4H-SiC offers higher electron mobility, lower on-resistance, and superior performance in high-power and high-frequency devices, making it the preferred material for MOSFETs and diodes.
Do you provide conductive or semi-insulating SiC substrates?
Yes, we offer N-type conductive 4H-SiC for power electronics and semi-insulating 4H-SiC for RF, microwave, and UV detector applications, with customizable doping levels.
Can the substrate be used directly for epitaxy?
Yes, our epi-ready 4H-SiC substrates feature CMP-polished Si-face surfaces with low defect density, suitable for MOCVD, CVD, and HVPE epitaxial growth of GaN, AlN, and SiC layers.
