Quartz Glass for Semiconductor Equipment – Quartz Glass (CTE 0.59 x 10^-6 /K, 260 nm – 2.5 um). No minimum order; DFM review included with every RFQ.
What quartz glass for semiconductor equipment actually buys from a glass shop: view ports, wafer carriers, plasma rings, chamber windows. The requirement underneath is plasma-resistant, particle-clean quartz and fused silica hardware. Quartz Glass is the fit here because it offers fused from natural quartz crystal.

DFM notes from the shop floor
The shop-floor rules that matter here:
- Material note: natural-quartz batches vary in metallic ppm, so semiconductor lots need certs per melt.
- Over-specification is the quiet budget killer: a 20/10 scratch-dig face costs roughly three times an 80/50 face, so grade each surface individually.
The full rules live in our tolerance design guide and holes and edges design guide.
Manufacturing capability
One material, many routes: on Quartz Glass we also quote laser cutting, etching, cnc machining, lapping, and multi-step drawings are the norm rather than the exception.

Frequently asked questions
How does Quartz Glass behave under heat?
CTE is 0.59 x 10^-6 /K and continuous service reaches 1,050 C continuous, which is what drives its use where fused from natural quartz crystal matters.
What do semiconductor equipment programs usually order?
View ports, wafer carriers, plasma rings, chamber windows. Typical spec: metallic impurities certified per melt, Ra < 0.8 um sealed faces.
Is there a minimum order for quartz glass for semiconductor equipment?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
How fast can prototypes ship?
Machined prototypes ship in 5 – 10 working days. Coated or bonded parts add 1 – 2 weeks depending on queue slots.
What files do you need for a quote?
A dimensioned PDF plus DXF or STEP geometry. If only a sketch exists, our drawing review service formalizes it before quoting.
