Method of forming self-aligned via

Last updated:

Abstract:

Electronic devices and methods to form electronic devices having a self-aligned via are described. An adhesion enhancement layer is utilized to promote adhesion between the conductive material and the sidewalls of the at least one via opening. The self-aligned vias decrease via resistance and reduce the potential to short to the wrong metal line.
