A method for manufacturing a semiconductor device having an excellent metallization is provided. The method includes the steps of a) providing a semiconductor substrate, b) forming a conductive layer on the semiconductor substrate, c) forming a dielectric layer on the conductive layer, d) forming a titanium nitride layer directly on the dielectric layer without contacting the conductive layer, and e) patternizing the titanium nitride layer, the dielectric layer and the conductive layer, wherein the dielectric layer is used for avoiding spontaneous electrochemical reaction between the titanium nitride layer and the conductive layer.
