Abstract
A method of forming an interconnection line of a semiconductor device includes the steps of forming an insulating layer on a substrate, forming a contact hole in the insulating layer, forming a first conductive material layer in the contact hole so that a top surface level of the first conductive material layer is the same as or higher than a top surface level of the insulating layer and so that a portion of the first conductive material layer remains on the insulating layer, and forming a second conductive material layer on the first conductive material layer as the portion of the first conductive material layer remaining on the insulating layer is removed.
