What are the specified film stack, roughness, and purity of the 8-inch gold-coated substrate?

The 8-inch single-sided gold-coated substrate is specified with a Cr 30 nm / Au 100 nm film stack, Ra < 1 nm film roughness, and film purity of at least 99.999%. The film stack is customizable, and the listed coating processes are electron-beam evaporation or magnetron sputtering.

Which substrate materials and coating processes are compatible with this gold-coated substrate?

This substrate is available on silicon wafer, glass, quartz, or sapphire, and can be fabricated by electron-beam evaporation or magnetron sputtering. Substrate dimensions, thickness, and film stack are customizable, but the substrate type and coating process should be confirmed before quotation.

What configuration details must be confirmed before ordering this 8-inch gold-coated substrate?

The 8-inch size, single-sided coating configuration, Cr 30 nm / Au 100 nm film stack, substrate type, substrate thickness, and coating process should be confirmed before quotation. Because the available substrate materials are silicon, glass, quartz, or sapphire, custom dimensions and intended integration requirements should be included in the request.

Assessment

This 8-inch gold-coated substrate with a Cr 30 nm / Au 100 nm film stack on a choice of silicon, glass, quartz, or sapphire substrates offers an ultra-smooth surface (Ra < 1 nm) and high film purity (≥ 99.999%), making it suitable for demanding applications in spectroscopy, electrochemistry, and surface science, though the single-sided coating and custom substrate requirements add procurement complexity.

Positive

Ultra-low surface roughness: Ra < 1 nm roughness minimizes scattering and ensures consistent surface properties for surface-enhanced spectroscopy or thin-film growth.
High-purity gold film: Film purity ≥ 99.999% reduces contamination risk, critical for electrochemical and catalytic applications where surface cleanliness determines performance.

Trade-offs

Custom substrate confirmation required: Substrate type (silicon, glass, quartz, or sapphire) and dimensions must be specified and confirmed before quotation, adding lead time and potential compatibility issues.
Single-sided coating limits applications: Only one side is coated with the gold film stack; double-sided or full-area coating is not available, which may restrict use in transmission-based setups or back-contact configurations.
