QUARTZ SUBSTRATES / WAFERS

Features of Synthetic Quartz Glass Substrates include:
– Purity: High purity levels eliminates contamination in the quartz substrates.
– Chemical resistance: Excellent thermal shock resistance and quartz glass is chemically inert to most elements and compounds including virtually all acids.
– Heat resistance: High dimensional stability of the quartz glass over a wide temperature range with extremely low coefficient of thermal expansion.
– Transparency: Quartz glass allow a high transmission over a wide range of wavelengths from UV to IR.
– Fluorescence: No fluorescence over a wide range of wavelengths from UV to IR.
– Dielectric properties: Low dielectric loss even at GHz frequencies.
– Surface: High flatness, high uniformity of thickness and smooth surfaces, attributed to the techniques developed for quartz glass photomask substrates used in LSI manufacturing.
