摘要:A method of forming a metal wiring in a semiconductor device. A copper wiringis formed by means of CECVD method by which a chemical enhancer layer is utilized forincreasing the deposition speed of copper. The damascene pattern is filled by means of
MOCVD method using a copper precursor in order to increase the deposition speed. Thechemical enhancer layer rises to the surface of copper after deposition of copper by aCECVD method and then the relatively high resistivity chemical enhancer layer that hasrisen to the surface of copper by plasma process is removed. Therefore, the ultra-finedamascene pattern can be rapidly filled with copper without increasing the resistance ofthe copper wiring.
