What surface roughness and film purity are specified for the 12-inch double-sided gold-coated substrate?

The 12-inch double-sided gold-coated substrate is specified with Ra < 1 nm surface roughness and film purity of at least 99.999%. The listed film stack is Cr 30 nm / Au 100 nm, and both electron-beam evaporation and magnetron sputtering are available processing routes.

Which substrate materials and coating configurations are available for the 12-inch double-sided gold-coated substrate?

The substrate can be silicon wafer, glass, quartz, or sapphire, with double-sided coating as the listed configuration. Substrate size, specification, and thickness can be customized, and the Cr 30 nm / Au 100 nm film stack is also listed as customizable.

What details must be confirmed before ordering the 12-inch double-sided gold-coated substrate?

Size, double-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.

Assessment

This 12-inch double-sided gold-coated substrate with Cr 30 nm / Au 100 nm film stack offers ultra-smooth surface (Ra < 1 nm) and high film purity (≥99.999%) via e-beam evaporation or magnetron sputtering, making it suitable for precision optical and electronic applications, though substrate type and dimensions must be confirmed prior to fabrication.

Positive

Ultra-smooth surface finish: Film roughness Ra < 1 nm ensures low scatter and high uniformity for sensitive optical or metrology applications.
High film purity and versatility: Film purity ≥ 99.999% minimizes contamination; double-sided coating and multiple substrate options (silicon, glass, quartz, sapphire) support diverse experimental or device integration needs.

Trade-offs

Customization requires pre-approval: Substrate type, thickness, dimensions, and coating process must be confirmed before quotation, adding lead time and requiring detailed specification upfront.
Handling and integration constraints: The 12-inch size and delicate coating (Cr/Au stack) necessitate careful substrate matching and surface treatment confirmation, with potential fragility during handling or further processing.
