ABSTRACT:
Disclosed are methods of manufacturing semiconductor devices, which may solve problems such as a short of upper wiring, etc., which are caused by a metal residue generated during chemical mechanical polishing of metallization of the semiconductor device, by depositing a predetermined insulating layer on the metal residue. The method may include forming a first insulating layer having an opening on a semiconductor substrate, depositing a metal layer on the first insulating layer to sufficiently fill the opening, planarizing the metal layer to expose the first insulating layer, forming a second insulating layer on the exposed first insulating layer and the metal layer, selectively etching and removing the second insulating layer to expose the metal layer, and forming a metallization layer on the metal layer.
