What surface roughness and film purity are specified for the 4-inch double-sided platinum-coated substrate?
The listed coating specification is Ra ≤ 1 nm surface roughness and ≥ 99.999% film purity for the Ti 30 nm / Pt 100 nm film stack. These values apply to the double-sided coating configuration on the 4-inch substrate.
Which substrate materials can be used with the Atomfair 4-inch platinum-coated substrate?
The substrate can be silicon, glass, quartz, or sapphire, with size, specification, and thickness customizable. Because substrate type and thickness affect the final configuration, they must be confirmed before quotation along with the coating process.
What coating process options are available for this platinum-coated substrate and what must be confirmed before ordering?
Electron-beam evaporation and magnetron sputtering are both listed as available coating processes. The 4-inch size, double-sided coating, Ti 30 nm / Pt 100 nm film stack, substrate type, substrate thickness, and coating process must be confirmed before quotation.
This 4-inch double-sided Pt-coated substrate with a Ti 30 nm / Pt 100 nm stack offers a consistent film roughness ≤1 nm and purity ≥99.999%, suitable for high-precision electrochemical or catalytic applications. Substrate options (silicon, glass, quartz, sapphire) provide flexibility in dielectric or thermal matching, but the coating process (e-beam or sputtering) and substrate thickness must be confirmed with each order.
Positive
- High-purity platinum coating: The film purity of ≥99.999% minimizes catalytic interference from trace contaminants, critical for sensitive electrochemical or surface-reaction studies.
- Substrate material flexibility: Availability in silicon, glass, quartz, or sapphire substrates allows matching to specific optical, thermal, or electrical isolation requirements of the application.
Trade-offs
- Customization requires pre-order confirmation: The substrate type, thickness, and coating process must be confirmed before quotation, introducing a lead-time dependency and limiting off-the-shelf availability.
- Film roughness specification is surface-average: The Ra ≤1 nm specification reflects average surface roughness and may not capture local defects or particle contamination that could affect submicroscale experiments.
