Abstract:
A liner-free or partial liner-free contact/via structure that is embedded within a dielectric capping layer and positioned between an electrically conductive structure and an overlying contact structure is provided.

Claim (Index 16):
A method of forming a semiconductor structure, the method comprising:\n providing an electrically conductive structure embedded in a first dielectric material layer; forming a dielectric capping layer on the first dielectric material layer, wherein the dielectric capping layer has a contact via/opening that physically exposes a surface of the electrically conductive structure; performing a volume expansion anneal to cause volume expansion of the electrically conductive structure and formation of a volume expanded electrically conductive structure, wherein the volume expanded electrically conductive structure has a lower portion embedded in the first dielectric material layer, and an upper portion that is at least partially included in a lower portion of the contact/via opening; and forming a contact structure above the dielectric capping layer, wherein the contact structure is embedded in a second dielectric material layer.
