PLATING METHOD AND PLATING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18263435 titled 'PLATING METHOD AND PLATING APPARATUS
Simplified Explanation
The patent application describes a plating method involving a preparation process, a first plating process, and a second plating process. The method involves preparing a substrate with a seed layer of cobalt or a cobalt alloy in a recess, performing displacement plating to replace the seed layer with copper, and then conducting reduction plating on the recess.
- The method involves preparing a substrate with a seed layer of cobalt or a cobalt alloy in a recess.
- Displacement plating is performed to replace the seed layer with copper using a first plating liquid.
- Reduction plating is then carried out on the recess using a second plating liquid containing a copper ion and a reducing agent.

Original Abstract Submitted
A plating method includes a preparation process; a first plating process; and a second plating process. In the preparation process, a substrate W having a seed layer of cobalt or a cobalt alloy formed in a recess is prepared. In the first plating process, a displacement plating processing is performed on the substrate W to replace a surface layer of the seed layer with copper by using a first plating liquid L containing a copper ion. In the second plating process, after the first plating process, a reduction plating processing is performed on the recess of the substrate W by using a second plating liquid L containing a copper ion and a reducing agent.
