GaN substrate quality is shaped by crystal structure, defect control, surface preparation, stress behavior, and inspection consistency. Gallium nitride is valued for power electronics, RF devices, LEDs, laser diodes, and advanced optoelectronic components because it has a wide bandgap of about 3.4 eV and can support high-voltage and high-frequency operation.
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.
