Abstract:
Embodiments of the present invention provide a method of forming a conductive stud contacting a semiconductor device. The method includes forming a protective layer covering the semiconductor device; selectively etching an opening down through the protective layer reaching a contact area of the semiconductor device, the opening being away from a protected area of the semiconductor device; and filling the opening with a conductive material to form the conductive stud. One embodiment may further include forming a dielectric liner directly on top of the semiconductor device, and forming the protective layer on top of the dielectric liner. Embodiments of the present invention also provide a semiconductor device made thereof.
