QUARTZ ETCH RINGJINGUI MANUFACTURING · SEMICONDUCTOR QUARTZ
From quartz.
To precision rings.
We can now manufacture quartz etching rings. Machined from our own quartz boules, with dimensions, geometry and surface requirements matched to your drawing.
What is an etching ring?
An annular component used in semiconductor plasma etching equipment. Quartz rings can provide insulation, separation or chamber shielding, depending on the tool and process design.
