The 8-inch quartz wafer is a precision substrate material fabricated from high-purity synthetic quartz glass (SiO₂), offering exceptional physical, chemical, and optical properties. With a standard diameter of 200mm (8 inches) and customizable thickness (e.g., 0.5mm–10mm), it is widely used in high-end semiconductor, optoelectronic, and optical applications. Due to its ultra-high purity (≥99.99%), low coefficient of thermal expansion, outstanding thermal stability, and superior UV-IR transmittance, quartz wafers are an ideal choice for critical processes such as photolithography, etching, and thin-film deposition. Additionally, their stable dielectric properties and radiation resistance make them suitable for high-precision sensors and aerospace-grade components.

1. Q: What is the standard thickness of an 8-inch quartz wafer?
A: The standard thickness ranges from 0.5mm to 1.0mm, with custom options up to 10mm for specific semiconductor applications.
2. Q: Why use quartz wafers instead of silicon wafers?
A: Quartz wafers provide superior UV transparency (>90% @193nm), higher thermal stability (up to 1730°C), and better chemical resistance than silicon for lithography and harsh environment processes.
