Abstract
A device including a p-type semiconductor device and an n-type semiconductor device on a semiconductor substrate. The n-type semiconductor device includes a gate structure having a high-k gate dielectric. A carbon dopant in a concentration ranging from 1×10atoms/cmto 1×10atoms/cmis present at an interface between the high-k gate dielectric of the gate structure for the n-type semiconductor device and the semiconductor substrate. Methods of forming the aforementioned device are also disclosed.
