Quartz rings can be customized according to customer requirements.
Purity: SiO₂ > 99.995%, with support for semiconductor-grade SiO₂ > 99.999%.

As a core component of coating equipment (such as evaporation coaters, sputtering coaters, PECVD, etc.), quartz rings are key auxiliary parts tailored to specific chamber structures and process requirements. Their characteristics must closely align with the demands of high temperature, vacuum, chemical environments, and precise temperature/field control during the coating process. They are indispensable consumables for silicon dioxide (SiO₂) coating processes.
