Method for manufacturing electronic grade synthetic quartz glass substrate
摘要:
An electronic grade synthetic quartz glass substrate having a recess, channel or step is manufactured by machining at least one surface of a synthetic quartz glass substrate having a maximum birefringence of up to 3 nm/cm in its entirety to form a recess, channel or step, and removing the residual stress due to machining.
