What surface roughness and film purity can be expected for the Atomfair 6-inch single-sided gold-coated substrate?

The listed specification is Ra < 1 nm roughness with film purity of at least 99.999%, based on a Cr 30 nm / Au 100 nm film stack. The coating is single-sided and can be produced by electron-beam evaporation or magnetron sputtering.

Which substrate materials are compatible with the 6-inch Cr/Au gold-coated substrate?

Silicon wafers, glass, quartz, and sapphire are listed as compatible substrate types. Substrate dimensions, specification, and thickness can be customized, and the Cr 30 nm / Au 100 nm film stack is also customizable.

What configuration details must be confirmed before ordering this gold-coated substrate?

The 6-inch size, single-sided coating, Cr 30 nm / Au 100 nm film stack, substrate type, substrate thickness, and coating process must be confirmed before quotation. Custom dimensions and specifications should be included in the request to ensure correct integration.

Assessment

The 6-inch single-sided gold-coated substrate with a Cr 30 nm / Au 100 nm film stack offers a smooth surface (Ra < 1 nm) and high purity (≥ 99.999%) suitable for sensitive surface science applications, but the coating's soft gold layer is physically vulnerable to mechanical contact and requires careful handling, while the Cr adhesion layer introduces a potential contamination risk in certain ultra-high-purity or bio-compatible workflows.

Positive

Ultra-smooth film surface: The Cr/Au coating achieves Ra < 1 nm roughness, minimizing scattering and enabling reproducible measurements in optical, plasmonic, or nanoscale imaging experiments.
High-purity gold layer: Film purity ≥ 99.999% reduces trace metal contamination risks, supporting consistent electrochemical and surface-interaction studies.

Trade-offs

Soft gold surface vulnerable to damage: Gold is mechanically soft; the 100 nm coating can be easily scratched, abraded, or contaminated by improper handling, requiring cleanroom-compatible tweezers and storage.
Chromium adhesion layer compatibility constraint: The Cr 30 nm interlayer may leach or react under aggressive solvents or at elevated temperatures, potentially interfering with high-purity UHV or biocompatibility protocols.
