FABRICATION METHOD FOR IMPROVING SURFACE PLANARITY AFTER TUNGSTEN CHEMICAL MECHANICAL POLISHING

A fabrication method for improving surface planarity after tungsten chemical mechanical polishing (W-CMP) is disclosed. The method forms contact holes and dummy patterns by performing two respective photolithography-and-etching processes to ensure that the dummy patterns have a depth smaller than that of the contact holes.
