    Silver-Coated Silicon Wafers (Ag/Cr on Si (100))
    Overview
    Our silver-coated silicon wafers are fabricated using high-vacuum magnetron sputtering to ensure excellent film uniformity, high reflectivity, and clean surface morphology.

    A thin chromium (Cr) adhesion layer (5 nm) is deposited between the silicon wafer and the silver film to provide strong interfacial bonding while maintaining optimal optical performance.

    These wafers are ideal for optical research, plasmonic studies, SERS applications, and high-reflectivity device fabrication.

    Layer Structure
    Standard structure:
    Ag (Silver layer)
    Cr (5 nm adhesion layer)
    Si (100) wafer

    Silver Thickness Options
    Standard Ag thickness:
    100 nm Recommended
    200 nm Recommended
    500 nm
    Custom thickness available upon request.

    Adhesion Layer
    Standard adhesion layer: Cr (5 nm)
    This thickness provides sufficient adhesion while minimizing optical absorption, making it suitable for reflective and plasmonic applications.
    Cr (10 nm) available upon request for enhanced adhesion requirements.

    Wafer Specifications
    Standard configuration:
    Orientation: Si (100)
