Quartz substrates and wafers are high-purity single crystal materials widely used in electronic, optical, RF, and sensor applications. Owing to their excellent piezoelectric properties, thermal stability, low dielectric loss, and outstanding chemical resistance, quartz wafers are essential materials for both advanced research and industrial device fabrication.

Single crystal quartz exhibits high optical transparency over a wide wavelength range, low thermal expansion, and stable mechanical performance, making it particularly suitable for MEMS devices, resonators, oscillators, surface acoustic wave (SAW) devices, and optical components. Compared with glass or amorphous silica, crystalline quartz provides superior uniformity, orientation control, and long-term reliability.

Our quartz substrates are manufactured with precise crystallographic orientation control, uniform thickness, and precision polishing to achieve low surface roughness and high flatness. Multiple crystal cuts and orientations are available to support diverse functional requirements, including frequency control, sensing, and optoelectronic integration.

Standard and custom wafer sizes can be supplied to meet both laboratory-scale research and commercial production needs. Additional processing options such as double-side polishing, edge shaping, and thickness customization are available upon request.

Frequently Asked Questions — Quartz Substrate / Wafer

What is a quartz substrate or wafer?

Quartz substrates are made from single crystal silicon dioxide (SiO₂) and are widely used in MEMS, RF, optical, and piezoelectric devices due to their excellent thermal stability, low dielectric loss, and piezoelectric properties.

What is the difference between quartz and fused silica?

Quartz is a crystalline material with well-defined crystal orientations and piezoelectric behavior, while fused silica is amorphous and non-piezoelectric. Quartz offers superior frequency stability and orientation-dependent properties.

What crystal orientations are available?

Common orientations include AT-cut, BT-cut, X-cut, Y-cut, and Z-cut quartz. Custom orientations can be supplied to meet specific frequency, sensing, or optical requirements.

What surface quality can be achieved?

Quartz wafers can be precision polished on one or both sides, achieving low surface roughness and high flatness suitable for MEMS fabrication, photolithography, and optical integration.

What applications commonly use quartz wafers?

Quartz substrates are widely used in MEMS sensors, resonators, oscillators, SAW/BAW devices, RF components, optical substrates, and precision timing applications.

Are custom sizes and thicknesses available?

Yes. Standard wafer sizes and custom dimensions, thicknesses, edge profiles, and polishing specifications are available upon request.

Are quartz substrates suitable for research and production?

Absolutely. Quartz wafers are supplied to universities, research laboratories, and OEM manufacturers, supporting both prototype development and commercial-scale production.
