Abstract
Exemplary semiconductor processing methods include forming a via in a semiconductor structure. The via may be defined in part by a bottom surface and a sidewall surface formed in the semiconductor structure around the via. The methods may also include depositing a tantalum nitride (TaN) layer on the bottom surface of the via. In embodiments, the TaN layer may be deposited at a temperature less than or about 200° C. The methods may still further include depositing a titanium nitride (TiN) layer on the TaN layer. In embodiments, the TiN layer may be deposited at a temperature greater than or about 300° C. The methods may additionally include depositing a fill-metal on the TiN layer in the via. In embodiments, the metal may be deposited at a temperature greater than or about 300° C.
