A method for fabricating a metal line in a semiconductor device is provided. The method includes: forming an inter-layer insulation layer on a substrate; forming a contact hole by etching the inter-layer insulation layer; forming a metal layer on the inter-layer insulation layer and the contact hole; etching a portion of the metal layer through performing a first etching process; and etching a remaining portion of the metal layer through performing a second etching process until the surface of the inter-layer insulation layer is exposed and a bottom portion of the metal line is sloped.
