Abstract
A method of forming a metal wiring in a semiconductor device can include forming an etch stop layer outside a contact hole formed in an insulation layer and avoiding forming the etch stop layer inside the contact hole. A conductive layer can be formed on the etch stop layer outside the contact hole and on an exposed conductive pattern inside the contact hole and on a sidewall of the contact hole and a metal layer can be formed on the conductive layer to fill the contact hole.
