6inch 4H-SiC substrate N-Type P-SBD Grade 350.0±25.0μm MPD≤0.5/cm2 Resistivity 0.015Ω•cm—0.025Ω•cm for power and microwave devices
Overview
SiC boules (crystals) are grown, machined into ingots, and then sliced into substrates, which are subsequently polished. A thin SiC epitaxial layer is then grown on top of this substrate to create an epi-wafer.
Silicon carbide, exceedingly hard, synthetically produced crystalline compound of silicon and carbon. Its chemical formula is SiC.
