Abstract

A semiconductor device includes a first gate structure including a first N-type high-k gate dielectric layer, a second gate structure comprising a first P-type high-k gate dielectric layer, a third gate structure including a second N-type high-k gate dielectric layer, and a fourth gate structure including a second P-type high-k gate dielectric layer. The first N-type high-k gate dielectric layer includes an N-type dipole material with a first concentration. The first P-type high-k gate dielectric layer includes a P-type dipole material with a second concentration. The second N-type high-k gate dielectric layer includes the N-type dipole material with a third concentration. The second P-type high-k gate dielectric layer includes the P-type dipole material with a fourth concentration. The first concentration is higher than the third concentration, and the second concentration is higher than the fourth concentration.
