What surface roughness and film purity does the Atomfair 8-inch double-sided gold-coated substrate specify?
The 8-inch double-sided gold-coated substrate is listed with a film roughness of Ra < 1 nm and a film purity of at least 99.999%. The standard film stack is Cr 30 nm / Au 100 nm, and the coating can be applied by electron-beam evaporation or magnetron sputtering.
Which substrate materials are compatible with the Atomfair 8-inch Cr/Au double-sided coated substrate?
Silicon wafer, glass, quartz, and sapphire are the listed substrate types for this 8-inch double-sided coated substrate. Substrate dimensions, specification, and thickness can be customized, and Atomfair requires confirmation of substrate type, surface treatment, and intended integration requirements before quotation.
What configuration details must be confirmed before Atomfair will quote this 8-inch gold-coated substrate?
Atomfair requires confirmation of the 8-inch size, double-sided coating, Cr 30 nm / Au 100 nm film stack, substrate type, substrate thickness, and coating process before quotation. Custom dimensions and specifications should be included in the request.
The 8-inch double-sided gold-coated substrate with Cr 30 nm / Au 100 nm film stack offers high film purity (≥99.999%) and low surface roughness (Ra < 1 nm), suitable for demanding optical or electrochemical applications. Its customizable substrate options (silicon, glass, quartz, sapphire) and dual coating processes (electron-beam evaporation, magnetron sputtering) provide flexibility, but the specified film stack and double-sided configuration impose a higher fabrication cost and require careful process validation prior to quotation.
Positive
- Ultra-low roughness and high film purity: Roughness of Ra < 1 nm and film purity ≥ 99.999% minimize scattering and contamination, making this substrate suitable for high-precision optical coatings or electrode interfaces where surface quality directly impacts performance.
- Flexible substrate and process compatibility: Compatibility with silicon, glass, quartz, or sapphire substrates and both electron-beam evaporation and magnetron sputtering allows the substrate to be tailored to specific thermal, optical, or mechanical requirements for research or device integration.
Trade-offs
- Customization requires pre-quotation validation: Substrate type, thickness, dimensions, and coating process must be confirmed before quotation, adding a pre-purchase engineering step that may delay procurement for standard lab supplies.
- Double-sided coating increases handling complexity: The double-sided Cr/Au coating imposes tighter handling and storage requirements to avoid front-to-back contamination or mechanical damage, and may not be compatible with single-sided integration workflows.
