    Platinum-Coated Silicon Wafers (Pt/Ti on Si (100))
    Overview
    Our platinum-coated silicon substrates are fabricated using high-vacuum magnetron sputtering to ensure uniform thickness, excellent adhesion, and high surface quality suitable for advanced research and device fabrication.
    A titanium (Ti) adhesion layer is deposited between the silicon substrate and the platinum layer to provide strong interfacial bonding and long-term stability.
    These substrates are widely used in electrochemical research, catalysis studies, fuel cell development, and MEMS fabrication.

    Layer Structure
    Standard structure:
    Pt (Platinum layer)
    Ti (10 nm adhesion layer)
    Si (100) Wafer

    Adhesion Layer
    Standard adhesion layer: Ti (10 nm)
    This configuration is widely used in electrochemical and microfabrication applications due to its strong adhesion and stable interface.

    Optional: Ti (20 nm)
    Recommended for thicker Pt films (>500 nm) or high-temperature applications.

    Custom adhesion thickness available upon request.
