What roughness and purity specifications can be expected for the 2 inch double-sided gold-coated substrate?

The listed coating achieves Ra < 1 nm surface roughness with film purity of at least 99.999%. The standard film stack is Cr 30 nm / Au 100 nm on both sides, with electron-beam evaporation or magnetron sputtering listed as the available coating routes.

Which substrate materials are compatible with the Atomfair 2 inch double-sided gold-coated substrate?

Silicon wafer, glass, quartz, and sapphire are all listed as compatible substrate types for the AF-GAU-2IN-D model. The standard coating is Cr 30 nm / Au 100 nm, and substrate dimensions, specification, and thickness can be customized.

Can the coating process and film stack be customized for this 2 inch double-sided gold-coated substrate?

Electron-beam evaporation and magnetron sputtering are the two listed coating processes for this double-sided substrate. The Cr 30 nm / Au 100 nm film stack is customizable, and substrate size, specification, and thickness can also be tailored. Coating process, substrate type, and substrate thickness must be confirmed before quotation.

Assessment

This 2-inch double-sided Au/Cr-coated substrate provides a research-grade film with Ra < 1 nm roughness and ≥ 99.999% purity, suitable for applications requiring low surface scatter and high chemical inertness. The Cr 30 nm adhesion underlayer and optional substrate materials (silicon, glass, quartz, sapphire) introduce substrate-dependent thermal expansion and processing compatibility trade-offs.

Positive

Ultra-low surface roughness: Ra < 1 nm ensures minimal optical scatter and consistent interfacial behavior for precision thin-film or spectroscopic applications.
High film purity: At least 99.999% purity reduces contamination risk in sensitive chemical or electrochemical environments, improving reproducibility.

Trade-offs

Substrate-dependent thermal compatibility: Available substrate materials (silicon, glass, quartz, sapphire) have different thermal expansion coefficients that must be matched to the intended deposition or annealing process to avoid film delamination.
Custom configuration requires quotation: Substrate type, thickness, and coating process must be confirmed before order, adding lead time and requiring buyer specification accuracy.
