Abstract:
A semiconductor device includes a substrate and a gate structure on the substrate, in which the gate structure includes a high-k dielectric layer on the substrate and a bottom barrier metal (BBM) layer on the high-k dielectric layer. Preferably, the BBM layer includes a top portion, a middle portion, and a bottom portion, the middle portion being a nitrogen rich portion, the top portion and the bottom portion being titanium rich portions, and the top portion, the middle portion, and the bottom portion are of same material composition.

Claim (Index 5):
The semiconductor device of  claim 1 , wherein the nitrogen-to-titanium ratio of the middle portion is 1:1.2 to 1:1.
