Plating method, interconnection forming method, and apparatus for carrying out those methods

摘要

The present invention relates to a plating method for use in forming a liner for plating in a conductor-embedding fine recess that is defined in a surface of a semiconductor substrate, and an interconnection forming method for use in forming an interconnection using such a liner, and characterized by reducing an organic metal compound in a nonaqueous solvent to plate a surface of a base material with metal. The plating method can easily be used similarly to an aqueous electroless plating process and is capable of forming a defect-free sound metal plated layer on the surface of a substrate which has a fine recess or the like for embedding a conductor therein, and the interconnection forming method is capable of forming an embedded interconnection that comprises a defect-free sound electric conductor in a fine recess.
