Product Specification

Copper-Plated Monocrystalline Silicon Wafer

High Adhesion, Excellent Conductivity, and Customizable Metallization Solutions

Product Overview

Copper-plated monocrystalline silicon wafers are manufactured by depositing a uniform copper layer onto high-quality single crystal silicon substrates through precision surface treatment and metallization processes. By combining the excellent mechanical and electrical properties of monocrystalline silicon with the superior electrical conductivity, thermal conductivity, and solderability of copper, this product is widely used in semiconductor packaging, MEMS fabrication, sensors, power devices, wafer-level interconnection, and R&D applications.

We offer flexible customization options including single-side copper plating, double-side copper plating, localized copper coating, and tailored wafer specifications to meet both prototype development and volume production requirements.

Key Features

Excellent Electrical and Thermal Conductivity

The copper layer provides outstanding electrical and thermal performance, helping improve signal transmission, current carrying capability, and heat dissipation in advanced electronic applications.

Uniform and Dense Copper Coating

With controlled plating technology, the copper layer is even, compact, and stable across the wafer surface, supporting better consistency in downstream manufacturing processes.

Strong Adhesion to Silicon Substrate

Through optimized surface preparation and interface treatment, the copper coating achieves strong adhesion to the monocrystalline silicon wafer, reducing the risk of peeling or delamination during cutting, bonding, soldering, or packaging.

Compatible with Various Post-Processing Steps

The product is suitable for subsequent processes such as photolithography, etching, dicing, welding, bonding, and packaging, making it a reliable base material for microfabrication and device integration.
