Granted: 2000-09-11
Abstract: A copper conductive wiring process comprises the following steps. First, an insulating layer is formed on the semiconductor substrate. Then, the trench and the dielectrics opening are formed on the insulating layer sequentially, wherein the opening of the dielectrics is sited below the trench. Next, the thin first barrier layer and the second barrier layer are deposited orderly on the trench and dielectrics opening, wherein the material of the first barrier layer is titanium and the material of the second barrier layer is titanium nitride. Next, a photolithography and etch process is performed to remove the first barrier layer on the peripheral of the trench, so as to leave the first and the second barrier layer in between the dielectrics opening. This step is the characteristic of this invention, which can avoid the phenomena of severe dishing and oxide erosion occurred on subsequent metal copper polishing that further influences the copper resistance value and the degree of planarization. Next, the copper is deposited and filled up the trench and dielectrics opening so as to proceed a polishing step to remove the excessive metal copper on the insulating layer.
