Abstract:
The present disclosure provides methods for forming conductive features in a dielectric layer without using adhesion layers or barrier layers and devices formed thereby. In some embodiments, a structure comprising a dielectric layer over a substrate, and a conductive feature disposed through the dielectric layer. The dielectric layer has a lower surface near the substrate and a top surface distal from the substrate. The conductive feature is in direct contact with the dielectric layer, and the dielectric layer comprises an implant species. A concentration of the implant species in the dielectric layer has a peak concentration proximate the top surface of the dielectric layer, and the concentration of the implant species decreases from the peak concentration in a direction towards the lower surface of the dielectric layer.

Claim (Index 21):
A method for semiconductor processing, the method comprising:\n depositing a dielectric material over a substrate; forming an opening in the dielectric material to expose a conductive feature; filling the opening with a conductive material, wherein a gap is interposed between the conductive material and a sidewall of the opening; performing a first implantation process to implant an implant species in the dielectric material, wherein a width of the gap decreases after performing the first implantation process; and after performing the first implantation process, performing a first planarization process to remove a portion of the conductive material.
