The substrate requires careful selection of substrate type, surface treatment, and integration requirements to ensure compatibility. The coating process (electron-beam evaporation or magnetron sputtering) must be confirmed for the intended application.

Substrate Compatibility: Select the substrate type (silicon, glass, quartz, or sapphire) that matches the intended integration requirements.
Coating Process Confirmation: Confirm that the chosen coating process (electron-beam evaporation or magnetron sputtering) is suitable for the substrate material.
Surface Treatment Verification: Verify that the surface treatment of the substrate is compatible with the gold coating adhesion.

FAQ

What surface roughness and film purity specifications are provided for the 2 inch single-sided gold-coated substrate?

The listed specification is Ra < 1 nm surface roughness with a film purity of at least 99.999%. These values apply to the Cr 30 nm / Au 100 nm film stack on the 2 inch single-sided coated substrate. Electron-beam evaporation and magnetron sputtering are both listed as available coating processes.

Which substrate materials can be selected for the ATOMFAIR AF-GAU-2IN-S gold-coated substrate, and can dimensions be customized?

The available substrate types are silicon wafer, glass, quartz, or sapphire. Substrate size, specification, and thickness can be customized, so the 2 inch format can be adapted to the required experimental configuration. Substrate type, thickness, and coating process must be confirmed before quotation.

What information must be specified before ordering the 2 inch Cr/Au coated substrate to avoid integration issues?

Before quotation, the 2 inch size, single-sided coating, Cr 30 nm / Au 100 nm film stack, substrate type, substrate thickness, and coating process should be confirmed. Custom dimensions and specifications should be included in the request, and the intended integration requirements should be confirmed. This ensures the substrate, surface treatment, and intended application are compatible.

Assessment

This 2-inch gold-coated substrate with a Cr 30 nm / Au 100 nm film stack achieves surface roughness less than 1 nm and film purity of at least 99.999%, making it suitable for demanding optical and surface science applications where low scatter and high chemical stability are required. The single-sided coating and customizable substrate options (silicon, glass, quartz, sapphire) allow integration into various experimental setups, but users must coordinate substrate selection, coating process, and dimensions at quotation stage.

Positive

Ultra-smooth gold surface: Sub-nanometer surface roughness (Ra < 1 nm) ensures minimal optical scatter and uniform film quality for high-precision measurements or reflectivity standards.
High gold film purity: Gold film purity of ≥ 99.999% (5N) minimizes contamination from trace metals, preserving electrical and chemical stability in sensitive experimental environments.

Trade-offs

Custom quote requires specification: Substrate type, thickness, and coating process must be confirmed before quotation, adding lead time and requiring technical coordination for non-standard orders.
Single-sided coating constraint: Single-sided coating limits use to applications needing only one reflective or conductive surface, requiring additional handling or substrate selection for double-sided needs.
