Quartz glass wafers are high-purity silicon dioxide (SiO\u2082) substrates widely used in semiconductor fabrication, optical systems, and precision electronic devices. Owing to their excellent thermal stability, extremely low thermal expansion coefficient, strong chemical resistance, and high optical transmission, quartz glass wafers play an important role in advanced manufacturing fields such as micro-electromechanical systems (MEMS), CMOS
