More info

Quartz Glass Wafer is an essential material in the semiconductor industry, known for its high purity, thermal stability, and excellent electrical insulation. As an amorphous form of SiO2, it is ideal for high-temperature processes such as chemical vapor deposition (CVD) and epitaxial growth. Its exceptional transparency in UV and IR spectra makes it suitable for lithography, etching masks, and optical applications. Additionally, its low absorption and high damage threshold make it valuable for precision laser processing. We offer Quartz Glass Wafers in various diameters from 2 inches to 12 inches, with customizable thicknesses down to 100 microns. Advanced surface inspection tools, including optical profilers and wafer defect detection systems, ensure top-quality standards. Heeger Materials provides high-quality Quartz Glass Wafers to meet diverse industry needs.
