Aspects generally relate to methods, systems, and apparatus for processing substrates using one or more amorphous carbon hardmask layers. In one aspect, film stress is altered while facilitating enhanced etch selectivity. In one implementation, a method of processing a substrate includes depositing one or more amorphous carbon hardmask layers onto the substrate, and conducting a rapid thermal anneal operation on the substrate after depositing the one or more amorphous carbon hardmask layers. The rapid thermal anneal operation lasts for an anneal time that is 60 seconds or less. The rapid thermal anneal operation includes heating the substrate to an anneal temperature that is within a range of 600 degrees Celsius to 1,000 degrees Celsius. The method includes etching the substrate after conducting the rapid thermal anneal operation.

Interconnect structures on a substrate have low resistivity and high dopant interfaces. In some embodiments, the structures may have an opening with a sidewall from an upper surface to an underlying metallic layer of copper, a barrier layer of tantalum nitride formed on the sidewall of the opening, a liner layer of cobalt or ruthenium formed on the barrier layer and on the underlying metallic layer, a first copper layer with a dopant with a first dopant content formed on the liner layer and filling a lower portion of the opening to form a via-the first dopant content is approximately 0.5 percent to approximately 10 percent, and a second copper layer with the dopant with a second dopant content formed on the first copper layer and filling the at least one opening—the second dopant content is more than zero to approximately 0.5 percent of the dopant and is less than the first dopant content.
