Copper-Coated Silicon Wafers (Cu/Ti on Si (100))
Overview
Our copper-coated silicon wafers are fabricated using high-vacuum magnetron sputtering to ensure uniform thickness, strong adhesion, and clean surface morphology suitable for electrochemical research and microfabrication.
A titanium (Ti) adhesion layer is deposited between the silicon substrate and the copper film to enhance interfacial bonding and long-term film stability.
These Cu-coated wafers are widely used in CO2 reduction research, electrochemical studies, electrode development, seed layer applications, and thin film device fabrication.
