Abstract

A semiconductor device includes a first channel region disposed in a first device region over a substrate; a first gate dielectric layer disposed over the first channel region; a second gate dielectric layer disposed over the second channel region; and a gate electrode disposed over the first gate dielectric layer. The first gate dielectric layer includes a first dipole dopant and the second gate dielectric layer includes a second dipole dopant embedded therein. A boundary between the first gate dielectric layer and the second gate dielectric layer contains the first dipole dopant and the second dipole dopant.
