Abstract
A method is disclosed for manufacturing a semiconductor device. Initially, a conductive layer is formed over a cell array region, in which high-integrated devices are formed, and over a non-cell region, which functions to assist a proper formation of the cell array region. An etching mask pattern is then formed over the conductive layer to form a conductive pattern over the cell array region and to remove the conductive layer formed on the non-cell region. The conductive pattern is actually formed by etching the conductive layer. An ion-assisted plasma etching is then implemented to form a pattern on the cell array region. This prevents the generation of arcing caused by independent conductive patterns formed on the non-cell region during the ion-assisted plasma etching.
