Disclosed herein is a method of making integrated circuits. In one
embodiment the method includes forming tungsten plugs in the integrated
circuit and forming electrically conductive interconnect lines in the
integrated circuit after formation of the tungsten plugs. At least one
tungsten plug is electrically connected to at least one electrically
conductive interconnect line. Thereafter at least one electrically
conductive interconnect line is contacted with water for a period of time
less than 120 minutes.
