Abstract

The present invention relates to a semiconductor device and a method for manufacturing the same. The semiconductor device has an embedded interconnect structure in which an electric conductor, such as copper or silver, is embedded in fine recesses formed in a surface of a semiconductor substrate, and also has a protective film formed on surfaces of exposed interconnects that define the interconnect structure, to protect the interconnects. The protective film has a flattened surface.
