Abstract

An insulation layer may be formed on an object having a contact region. The insulation layer may be partially etched to form an opening exposing the contact region. A material layer including silicon and oxygen may be formed on the exposed contact region. A metal layer may be formed on the material layer including silicon and oxygen. The material layer including silicon and oxygen may be reacted with the metal layer to form a metal oxide silicide layer at least on the contact region. A conductive layer may be formed on the metal oxide silicide layer to fill up the opening.
