How do the specified Ra <0.5 nm roughness, <5 µm flatness, and Scratch/Dig 40/20 surface quality affect optical substrate performance?
This 6 inch (150 mm) quartz glass substrate is supplied with Ra <0.5 nm roughness, <5 µm flatness, and Scratch/Dig 40/20 surface quality. These specifications are directly relevant for minimizing optical scatter, preserving flatness for precision processing, and limiting surface defects in demanding photonics, lithography, and metrology applications.
Is this 6 inch (150 mm) quartz substrate with a 47.5 mm flat/notch compatible with standard 150 mm wafer process lines?
Yes, the substrate is specified as 6 inch (150 mm) with a 47.5 mm flat length/notch, matching the physical format used by 150 mm wafer carriers and process tools. However, confirm that your specific tooling accepts quartz glass substrates, because quartz differs from silicon in thermal, electrical, and mechanical handling characteristics.
What package configuration and handling precautions are recommended for preserving the quartz substrate surface quality?
The product is supplied as 10 pieces per box, and the substrates should be kept in the original packaging until use to protect the polished surfaces. Use clean, non-contact handling practices to avoid contaminating or scratching the surface and to preserve the stated Ra <0.5 nm roughness and Scratch/Dig 40/20 quality.
This 6-inch quartz glass substrate is supplied with Ra <0.5 nm roughness, <5 µm flatness, Scratch/Dig 40/20 surface quality, and a 1000 ±25 µm thickness, defining a research-grade optical substrate with explicit surface specifications.
Positive
- Sub-nanometer surface roughness: Ra <0.5 nm roughness with <5 µm flatness is supplied to specification, providing a well-defined surface geometry for optical substrate applications.
- Scratch/Dig 40/20 surface quality: The 40/20 scratch-dig specification quantifies allowable surface defects, giving buyers a clear benchmark for inspection and acceptance.
Trade-offs
- Nominal thickness tolerance of ±25 µm: The 1000 µm thickness is specified as typical with ±25 µm tolerance, so downstream processes requiring tighter thickness control must screen or request a more restrictive tolerance.
