    Abstract: A metal line of a semiconductor device and a method of forming the same are provided to reduce time delay due to parasitic capacitance by preventing undercut under a plating layer. An electrode(104) is formed in a substrate(100), and a mold layer having a groove exposing the electrode to the substrate is formed. A conductive film covers a floor and a side wall of the groove in conformal so that the conductive film is in contact with the electrode. A seed metal film(112a) is connected to a conductive film, and it is restricted on the bottom of the groove, and a metal pattern is grown up from the seed metal film and the groove is buried.
