| High Light | Titanium-coated silicon wafer substrate ，Copper-coated semiconductor wafer ，Metal-coated silicon wafer for semiconductors | ||
Ti/Cu metal-coated silicon wafers are fabricated by depositing a titanium (Ti) adhesion layer followed by a copper (Cu) conductive layer on high-quality substrates using standard magnetron sputtering. The Ti layer enhances film adhesion and interfacial stability, while the Cu layer provides excellent electrical conductivity. Multiple wafer sizes, conductivity types, orientations, resistivity ranges, and film thicknesses are available, with full customization supported for research and industrial prototyping.
Film stack: Substrate + Adhesion layer (Ti) + Coating layer (Cu)
Deposition process: Standard magnetron sputtering (optional: thermal evaporation / electroplating by request)
Key features: Strong adhesion, low resistance surface, suitable for subsequent lithography, electroplating build-up, or device fabrication.

Q1: Why is a Ti layer used under the Cu coating?
A: Titanium works as an adhesion (bonding) layer, improving the attachment of copper to the substrate and enhancing interface stability, which helps reduce peeling or delamination during handling and processing.
Q2: What is the typical Ti/Cu thickness configuration?
A: Common combinations include Ti: tens of nm (e.g., 10–50 nm) and Cu: 50–300 nm for sputtered films. Thicker Cu layers (µm-level) are often achieved by electroplating on a sputtered Cu seed layer, depending on your application.
Q3: Can you coat both sides of the wafer?
A: Yes. Single-side or double-side coating is available upon request. Please specify your requirement when ordering.
