Abstract:
Generally, the present disclosure provides example embodiments relating to conductive features, such as metal contacts, vias, lines, etc., and methods for forming those conductive features. In a method embodiment, a dielectric layer is formed on a semiconductor substrate. The semiconductor substrate has a source/drain region. An opening is formed through the dielectric layer to the source/drain region. A silicide region is formed on the source/drain region and a barrier layer is formed in the opening along sidewalls of the dielectric layer by a same Plasma-Enhance Chemical Vapor Deposition (PECVD) process.
