What is the significance of the Scratch/Dig 40/20 surface quality specification for this 2-inch quartz glass substrate?
The Scratch/Dig 40/20 specification ensures minimal surface defects, which is critical for optical applications requiring low light scattering and high transmission. This surface quality is standard for research-grade substrates used in UV optics and thin-film coatings.
How do the <0.5 nm roughness and <5 µm flatness of this quartz glass substrate impact its performance in precision optical or photonic applications?
The Ra <0.5 nm roughness provides an ultra-smooth surface minimizing scattering losses, while the <5 µm flatness ensures uniform thickness across the substrate. These specifications are essential for maintaining consistent optical path lengths in interferometry and for achieving uniform film deposition in photonic device fabrication.
What is the purpose of the 16 mm flat on this 2-inch quartz glass substrate?
The 16 mm flat provides a reference orientation for alignment in standard wafer handling systems. This feature is typical for 2-inch substrates used in semiconductor and thin-film research, enabling consistent positioning during processing and metrology.
Quartz glass substrate (2 inch, 50.8 mm) with Ra <0.5 nm roughness, Scratch/Dig 40/20 surface quality, and <5 µm flatness offers excellent optical surface quality for thin-film deposition and coatings, but the 500 ± 25 µm thickness requires careful handling to avoid breakage and the flatness tolerance may not satisfy sub-micron planarity requirements.
Positive
- Ultra-low surface roughness: Ra <0.5 nm ensures minimal scattering, ideal for high-precision optical coatings and thin-film deposition.
- High surface quality specification: Scratch/Dig 40/20 rating meets stringent optical substrate requirements, reducing defects in transmitted or reflected light.
Trade-offs
- Thin substrate fragility: At 500 ± 25 µm thickness, the substrate is prone to breakage during handling or processing without proper support.
- Flatness constraint for advanced applications: Flatness <5 µm may be insufficient for sub-micron planarity demands such as lithography masks or interferometry.
