What are the typical film roughness and purity specifications for the 12-inch gold-coated substrate?

The film roughness is specified as Ra < 1 nm, and the film purity is at least 99.999%. These parameters are directly listed in the product specifications for the Cr 30 nm / Au 100 nm film stack.

What substrate materials are available for this gold-coated substrate, and can the dimensions be customized?

The substrate can be silicon wafer, glass, quartz, or sapphire. The product description states that substrate size, specification, and thickness can be customized, and custom dimensions should be included in the quotation request.

What coating processes are used to deposit the Cr/Au film stack, and what parameters must be confirmed before ordering?

The coating processes available are electron-beam evaporation and magnetron sputtering. Before quotation, the following parameters must be confirmed: size, coating configuration (single-sided), film stack (Cr 30 nm / Au 100 nm), substrate type, substrate thickness, and coating process.

Assessment

The 12-inch single-sided gold-coated substrate (Cr 30 nm / Au 100 nm) offers ultra-smooth (Ra < 1 nm) and high-purity (≥ 99.999%) films via electron-beam evaporation or magnetron sputtering, suitable for demanding research applications. The substrate choice among silicon, glass, quartz, or sapphire must be confirmed pre-quotation, adding a procurement step for end users.

Positive

Ultra-low film roughness: Ra < 1 nm surface roughness ensures minimal scattering and consistent interfacial properties for sensitive optical or electronic measurements.
High film purity: Purity ≥ 99.999% (5N) reduces contamination risks in thin-film deposition, important for reproducible device fabrication.

Trade-offs

Pre-quotation confirmation required: Substrate type, thickness, and coating process must be specified and confirmed before quotation, introducing lead-time variability for lab procurement.
Single-sided coating constraint: Coating is applied only to one side, requiring careful handling and potential additional backside passivation for dual-side applications.
