Abstract:
1. A method for fabricating a semiconductor device, comprising the steps of: (a) forming interconnect grooves in an insulating film on a substrate; (b) forming a copper film on the insulating film to fill the interconnect grooves; (c) polishing portions of the copper film existing outside the interconnect grooves to form interconnects; (d) performing a cleaning process on the substrate having been formed with the interconnects; (e) removing, after the cleaning process, moisture remaining around a portion of the insulating film exposed between the interconnects; and (f) coating an anticorrosive onto the surfaces of the interconnects after step (e), wherein step (e) includes a substep of desorbing, in a vacuum, water molecules adsorbed on the insulating film, and the anticorrosive is not exposed to step (e).
