Abstract:
A semiconductor device includes a transistor having a source/drain and a gate. The semiconductor device also includes a conductive contact for the transistor. The conductive contact provides electrical connectivity to the source/drain or the gate of the transistor. The conductive contact includes a plurality of barrier layers. The barrier layers have different depths from one another.

Claim (Index 13):
A method, comprising:\n providing a transistor having a source/drain and a gate, wherein a dielectric material is formed over the transistor; performing a plurality of etching and deposition cycles to form a plurality of barrier layers of a conductive contact of the transistor, wherein each cycle includes an etching process to etch an opening in the dielectric material and a deposition process to deposit a respective barrier layer in the etched opening, wherein the barrier layers are formed to have different depths from one another, wherein at least some of the cycles further include a resputtering process that is performed between the etching process and the deposition process, and wherein the resputtering process removes a bottom segment of the deposited barrier layer; and filling, with a conductive material, a last opening etched by a last one of the cycles, thereby forming the conductive contact of the transistor.
