Sapphire wafer orientation should be inspected because crystal plane direction affects epitaxial growth, optical behavior, mechanical response, etching performance, and process repeatability. A sapphire wafer is not only a hard transparent substrate.
JGS1 fused silica is chosen when a wafer needs strong UV transmission, stable thermal behavior, low impurity influence, and a smooth optical-grade surface. For semiconductor, photonics, optical inspection, sensor, and laboratory processing, the substrate must remain clear, stable, and clean through handling, coating, bonding, or high-temperature steps.
SiC wafer grade matters because silicon carbide devices often operate under high voltage, high temperature, high frequency, or harsh electrical stress. A substrate defect may look small during incoming inspection, but it can become a leakage path, epitaxy defect, breakdown point, yield loss, or long-term reliability risk after device fabrication.
