The substrate surface quality of Scratch/Dig 40/20 and roughness Ra <0.5 nm require contamination-free handling to avoid defects. Flatness below 5 um necessitates careful storage to prevent warping or mechanical stress.
- Surface Contamination Risk: Contact with bare skin or unclean surfaces can introduce particles or oils that degrade the specified Scratch/Dig 40/20 quality.
- Flatness Stability: Stacking or clamping the 1000 um thick substrates without proper support may induce bowing exceeding the <5 um flatness tolerance.
Inspect each substrate upon removal from the box for visible chips or scratches before use. Use cleanroom-grade gloves and a vacuum wand or edge-grip tweezers to avoid surface contact.
Required Equipment: Cleanroom-grade gloves, Vacuum wand or edge-grip tweezers
- Inspect packaging
Verify the box seal is intact and the substrates are separated by clean interleaving material before opening. - Don clean gloves
Put on powder-free cleanroom gloves to prevent oil or particulate transfer to the substrate surface. - Lift substrate safely
Use a vacuum wand or edge-grip tweezers to lift the substrate by its edges, avoiding contact with the polished faces. - Inspect surface
Hold the substrate under a bright light at an angle to check for visible scratches, chips, or contamination before processing. - Store flat
Place the substrate in a clean, flat container with the polished side up and separated from other substrates by clean wipes or spacers.
What are the specified roughness, flatness, and surface quality of this 6-inch quartz glass substrate, and how do these parameters affect its suitability for high-precision optical applications?
The substrate has Ra <0.5 nm roughness, <5 µm flatness, and Scratch/Dig 40/20 surface quality. These specifications ensure minimal optical scattering and uniform coating thickness, making it suitable for demanding optical applications.
What are the dimensions (diameter, thickness, flat length) of the 6-inch quartz glass substrate, and are they compliant with standard 150 mm wafer specifications?
The substrate is 150 mm (6 inch) diameter, with a typical thickness of 1000 ± 25 µm and a flat length of 47.5 mm. These dimensions conform to standard 150 mm wafer format, ensuring compatibility with typical wafer handling and processing equipment.
What is the package quantity for this 6-inch quartz glass substrate, and how is it supplied to maintain surface quality during storage?
The substrate is supplied in a box of 25 pieces. This packaging format helps protect the delicate surface quality (Ra <0.5 nm, Scratch/Dig 40/20) during storage and transport by minimizing physical contact and environmental exposure.
This 6-inch quartz glass substrate (AF-WF-S-GLAS-06IN-G076) offers a surface roughness of Ra <0.5 nm, flatness <5 µm, and Scratch/Dig 40/20 surface quality, making it suitable for demanding optical and thin-film applications where low scatter and precise planarity are required.
Positive
- Ultra-low surface roughness: Ra <0.5 nm roughness minimizes optical scatter and improves adhesion uniformity for thin-film deposition or photolithography processes.
- High surface quality grade: Scratch/Dig 40/20 specification ensures minimal surface defects, critical for high-precision optical coatings and semiconductor metrology.
Trade-offs
- Fragile handling required: Quartz glass substrates are brittle and require careful handling to avoid chipping or breakage during processing and transfer.
- Thickness tolerance constraint: The typical thickness of 1000 ±25 µm may limit compatibility with fixtures or processes requiring tighter thickness uniformity without custom specification.
