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 16):
The method of  claim 13 , wherein the performing of the plurality of etching and deposition cycles comprises:\n performing a first etching process to etch an opening in the dielectric material, wherein the opening is located over the source/drain or over the gate of the transistor; depositing a first barrier layer in the opening, the first barrier layer including sidewall segments joined by a bottom segment; removing the bottom segment of the first barrier layer; after the removing of the bottom segment of the first barrier layer, performing a second etching process to extend the opening downward; after the second etching process, depositing a second barrier layer in the opening, the second barrier layer including sidewall segments joined by a bottom segment, wherein portions of the sidewall segments of the second barrier layer are formed on the sidewall segments of the first barrier layer; removing the bottom segment of the second barrier layer; after the removing of the bottom segment of the second barrier layer, performing a third etching process to extend the opening further downward; after the third etching process, depositing a third barrier layer in the opening, the third barrier layer including sidewall segments joined by a bottom segment, wherein portions of the sidewall segments of the third barrier layer are formed on the sidewall segments of the second barrier layer; and filling the opening with a conductive material.
