Abstract
Integrated circuit devices include a semiconductor substrate having a first doped region and a second doped region having a different doping type than the first doped region. A gate electrode structure on the semiconductor substrate extends between the first and second doped regions and has a gate insulation layer of a first high dielectric constant material in the first doped region and of a second high dielectric constant material, different from the first high dielectric constant material, in the second doped region. A gate electrode is on the gate insulation layer.
