High-purity quartz.
Precision materials.
Proven processes.

Quartz sand, silica powders and process equipment for semiconductor, photovoltaic, optical and electronic manufacturing.

From ore to finished product

Our own resources, backed by purification and testing.

We assess the ore, design the purification process and verify the results through laboratory testing. Material properties and target quality guide equipment selection and operating conditions.

JINGUI MANUFACTURING · SEMICONDUCTOR QUARTZ

From quartz boules
to precision rings.

Quartz etching rings made to your drawing. We machine rings from our own quartz boules to meet your dimensional, geometry and surface requirements.

What is an etching ring?

A ring-shaped component used in semiconductor plasma etching equipment. Depending on the equipment and process design, quartz rings provide insulation, separation or chamber protection.
