Abstract: A semiconductor device including a MOS transistor is provided. The semiconductor device may include a first MOS transistor including first source/drain regions, a first semiconductor layer between the first source/drain regions, a first gate electrode structure, and a first gate dielectric structure; and a second MOS transistor including second source/drain regions, a second semiconductor layer between the second source/drain regions, a second gate electrode structure, and a second gate dielectric structure. The first gate dielectric structure and the second gate dielectric structure include a first common dielectric structure; the first gate dielectric structure includes a first upper dielectric on the first common dielectric structure; the second gate dielectric structure includes the first upper dielectric and a second upper dielectric; and one of the first upper dielectric and the second upper dielectric is a material forming a dipole layer.
