    摘要: A semiconductor device includes an interlayer insulation film, an underlying line provided in the interlayer insulation film, a liner film overlying the interlayer insulation film, an interlayer insulation film overlying the liner film. The underlying line has a lower hole and the liner film and the interlayer insulation film have an upper hole communicating with the lower hole, and the lower hole is larger in diameter than the upper hole. The semiconductor device further includes a conductive film provided at an internal wall surface of the lower hole, a barrier metal provided along an internal wall surface of the upper hole, and a Cu film filling the upper and lower holes. The conductive film contains a substance identical to a substance of the barrier metal. A highly reliable semiconductor device can thus be obtained.

    摘要: A semiconductor device according to the present invention is a semiconductor device having a first wiring formed in a first insulating layer and a second wiring formed in a second insulating layer formed on the first insulating layer and the first wiring. Here, at least one of the first wiring and the second wiring is a CuAl wiring. The second wiring is electrically connected to the first wiring at its via-plug portion, with a plurality of barrier layers interposed between the second wiring and the first wiring. In the barrier layers, a CuAl-contact barrier layer which is in contact with the CuAl wiring has a nitrogen atom content of less than 10 atomic %. Therefore, the present semiconductor device has high reliability and small variations in initial via resistance value.
