Substrate processing method and apparatus

摘要

A substrate processing apparatus can process a substrate having a metal film formed thereon. The substrate processing apparatus has a process unit configured to remove a native oxide of a metal film formed on a surface of a substrate. The substrate processing apparatus also has a planarization unit configured to planarize the metal film of the substrate. The process unit may comprise a wet process unit configured to dissolve the native oxide of the metal film in a chemical liquid or a dry process unit configured to reduce or etch the native oxide of the metal film with a gas.
