Abstract: PURPOSE: A method for manufacturing an interconnection of a semiconductor device is provided to eliminate remnants mainly composed of a barrier layer material and to control a bridge phenomenon in a subsequent process, by performing an etch-back process using plasma under a constant condition after a plug is formed. CONSTITUTION: An insulating layer is formed on a lower conductive layer(120) having a predetermined pattern on a semiconductor substrate(100). The insulating layer is etched to form a contact hole exposing a part of the surface of the lower conductive layer. A barrier layer and a metal layer are formed in the contact hole and on the insulating layer. A plug wherein the barrier layer and metal layer are filled up in the contact hole, is formed by planarization process using chemical mechanical polishing(CMP) method, so that the surface of the insulating layer is exposed. After the planarization process is performed on the entire surface of the insulating layer and plug by an etch-back process using plasma, remnants are eliminated. An upper metal layer(170) contacting the plug is formed.
