SiC wafer grade matters because silicon carbide is often used in devices that must handle high voltage, high temperature, high frequency, or harsh operating conditions. A small substrate defect may not look serious during incoming inspection, but it can become a leakage path, breakdown point, epitaxy issue, or reliability risk after device fabrication.
Selecting the right sapphire wafer surface finish depends on the process, not only the appearance of the wafer. Sapphire is extremely hard, chemically stable, electrically insulating, and suitable for optical and high temperature applications, but these advantages also make it difficult to grind and polish.
Sapphire wafers are used when a substrate must combine hardness, thermal stability, electrical insulation, and optical transmission. Synthetic sapphire is single crystal aluminum oxide, so its role is different from silicon or glass. It is chosen when the next process needs a tough, stable, and chemically resistant base.
