PRODUCTS & MATERIALS

Semi-Insulating SiC Wafers

Semi-Insulating SiC Wafers: Semi-insulating SiC is discussed for RF or research applications where substrate electrical isolation is important. Clarify resistivity measurement conditions and acceptable uniformity. For procurement, describe Diameter, thickness and tolerance, 4H/6H polytype, Si-face/C-face, off-axis angle, doping, grade, polish, defect limits. We discuss product options and inspection requirements case by case, rather than publishing unsupported stock or tolerance guarantees.
