More Information
Summary:A method of manufacturing a device includes exposing at least one of a source/drain contact plug or a gate contact plug to a metal ion source solution during a manufacturing process, wherein a constituent metal of a metal ion in the metal ion source solution and the at least one source/drain contact plug or gate contact plug is the same. If the source/drain contact plug or the gate contact plug is formed of cobalt, the metal ion source solution includes a cobalt ion source solution. If the source/drain contact plug or the gate contact plug is formed of tungsten, the metal ion source solution includes a tungsten ion source solution.
