Abstract:
A method of an aspect includes forming a first thicker layer of a first material over a first region having a first surface material by separately forming each of a first plurality of thinner layers by selective chemical reaction. The method also includes limiting encroachment of each of the first plurality of thinner layers over a second region that is adjacent to the first region. A second thicker layer of a second material is formed over the second region having a second surface material that is different than the first surface material.

Abstract:
Selective hardmask-based approaches for conductive via fabrication are described. In an example, an integrated circuit structure includes a plurality of conductive lines in an inter-layer dielectric (ILD) layer above a substrate. The plurality of conductive lines includes alternating non-recessed conductive lines and recessed conductive lines. The non-recessed conductive lines are substantially co-planar with the ILD layer, and the recessed conductive lines are recessed relative to an uppermost surface of the ILD layer. A dielectric capping layer is in recess regions above the recessed conductive lines. A hardmask layer is over the non-recessed conductive lines but not over the dielectric capping layer of the recessed conductive lines. The hardmask layer differs in composition from the dielectric capping layer. A conductive via is in an opening in the dielectric capping layer and on one of the recessed conductive lines. A portion of the conductive via is on a portion of the hardmask layer.
