Abstract:
Performance of a semiconductor device is improved. In one embodiment, for example, deposition time is increased from 4.6 sec to 6.9 sec. In other words, in one embodiment, thickness of a tantalum nitride film is increased by increasing the deposition time. Specifically, in one embodiment, deposition time is increased such that a tantalum nitride film provided on the bottom of a connection hole to be coupled to a wide interconnection has a thickness within a range from 5 to 10 nm.

Claim (Index 20):
A semiconductor device, comprising:\n an interconnection layer comprising:\n a first connection hole; \n a first interconnection trench connected with the first connection hole; \n a second connection hole formed in the same layer as the first connection hole; and \n a second interconnection trench formed in the same layer as the first interconnection trench, the second interconnection trench connected with the second connection hole, \n a first barrier conductor film formed such that the first barrier conductor film covers an inner surface of the first connection hole and an inner surface of the first interconnection trench; a second barrier conductor film formed such that the second barrier conductor film covers an inner surface of the second connection hole and an inner surface of the second interconnection trench; a first copper film formed on the first barrier conductor film such that the first copper film is buried in the first connection hole and the first interconnection trench, the first copper film including copper; and a second copper film formed on the second barrier conductor film such that the second copper film is buried in the second connection hole and the second interconnection trench, the second copper film including copper, wherein a width of the first interconnection trench is greater than a width of the second interconnection trench, wherein the first barrier conductor film is a stacked film of a first tantalum nitride film and a first tantalum film formed on the first tantalum nitride film, wherein the second barrier conductor film is a stacked film of a second tantalum nitride film and a second tantalum film formed on the second tantalum nitride film, wherein a first thickness of the first tantalum nitride film positioned at a bottom of the first connection hole is greater than a second thickness of the second tantalum nitride film positioned at a bottom of the second connection hole, wherein the first tantalum film positioned at the bottom of the first connection hole has a crystal structure of an \u03b1-Ta structure, and wherein the second tantalum film positioned at the bottom of the second connection hole has a crystal structure of a \u03b2-Ta structure.
