Precision Glass for Semiconductor Equipment

Precision Glass for Semiconductor Equipment: to-drawing tolerances with inspection reports. No MOQ, prototypes in 5-10 days, DFM review with every RFQ.

Industry Application July 28, 2026

Precision Glass for Semiconductor Equipment: custom precision glass machined to drawing with inspection reports. Single-piece prototypes to production volumes, quoted from your drawing.

precision glass for semiconductor equipment programs need plasma-resistant, particle-clean quartz and fused silica hardware. Typical parts: view ports, wafer carriers, plasma rings, chamber windows.

Design guidance

Three items decide most of the cost and lead time on this work:

  • 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.

Who orders this

Orders for precision glass for semiconductor equipment cluster in ccd inspection equipment (CCD cover plates, reference grids, stage glass); machine vision (camera windows, ring-light diffusers, calibration plates); led packaging (groove covers, phosphor carriers, package windows).

Buyer questions, answered

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.

Do parts ship with inspection data?

Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.

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.

FREQUENTLY ASKED QUESTIONS
Which fused silica grade should I choose — JGS1, JGS2 or JGS3?

JGS1 offers deep-UV transmission from about 185 nm (best for DUV lithography and UV laser optics). JGS2 transmits well from about 220 nm for standard UV-visible use at lower cost. JGS3 is optimized for visible-to-infrared and high-power laser work. The builder exposes a transmission-band requirement so you can specify the grade by application.

What wafer diameters and thicknesses are supported?

Common diameters are 2, 3, 4 and 6 inch (note 1 inch = 25.0 mm for quartz wafers, so a 4 inch wafer is 100 mm). Typical thicknesses are 200, 500, 700 and 1000 µm, with tighter thickness tolerance and TTV specifiable for polished optical grades.

Can I specify TTV, surface quality and a flat or notch?

Yes. You can set total thickness variation, scratch-dig surface quality (down to 40/20 or 20/10 for optical grade), single- or double-side polish, and a primary flat or notch for orientation.
