Abstract:
A method includes forming an opening in a dielectric layer, depositing a seed layer in the opening, wherein first portions of the seed layer have a first concentration of impurities, exposing the first portions of the seed layer to a plasma, wherein after exposure to the plasma the first portions have a second concentration of impurities that is less than the first concentration of impurities, and filling the opening with a conductive material to form a conductive feature. In an embodiment, the seed layer includes tungsten, and the conductive material includes tungsten. In an embodiment, the impurities include boron.

Claim (Index 21):
A method comprising:\n forming a semiconductor fin on a substrate; forming a source/drain region in the semiconductor fin; depositing a dielectric layer over the source/drain region; forming an opening in the dielectric layer to expose portions of the source/drain region; and forming a contact plug in the opening, comprising:\n depositing a first conductive material over surfaces of the dielectric layer and over the exposed portions of the source/drain region, the first conductive material comprising a first region and a second region, the first region being farther from the substrate than the second region; \n performing a plasma treatment process on the first conductive material, wherein after performing the plasma treatment process, the first region of the first conductive material has a lower concentration of impurities than the second region; and \n after performing the plasma treatment process, depositing a second conductive material on the first conductive material.
