What is Copper Electroplating?
Copper electroplating is a process where a thin layer of copper is deposited onto a conductive surface using an electrochemical method. It involves immersing the material in an electrolyte solution and applying an electrical current to adhere copper ions to the surface.
Why is Copper Electroplating Important?
Copper electroplating is essential in semiconductor fabrication due to its:
- Low Electrical Resistance: Enables faster signal transmission in integrated circuits.
- High Reliability: Enhances the durability of interconnects.
- Support for Miniaturization: Allows the creation of denser, more efficient components.
- Cost-Effectiveness: Offers precision and scalability for mass production.
Applications
Copper electroplating is used in:
- Integrated Circuits (ICs)
- Printed Circuit Boards (PCBs)
- MEMS Devices
- Advanced Packaging
