    Abstract: In some embodiments of the inventive subject matter, methods include forming an oxide layer on a semiconductor substrate, injecting nitrogen into the oxide layer to form a nitrogen injection layer and to change the oxide layer to an oxynitride layer, removing a part of the oxynitride layer to leave a portion of the oxynitride layer in a first area and expose the nitrogen injection layer in a second area and forming an insulating layer comprising a portion on the portion of the oxynitride layer in the first area and a portion on the nitrogen injection layer in the second area. The insulating layer may have a higher dielectric constant than the oxide layer.

    Abstract: An insulation layer is formed on a substrate having an NMOS region and a PMOS region defined therein. A first conductive layer is formed on the insulation layer in the PMOS region, leaving a portion of the insulation layer in the NMOS region exposed. Nitriding is performed to produce a first nitrogen concentration in the insulation layer in the NMOS region and a second nitrogen concentration less than the first nitrogen concentration in the insulation layer in the PMOS region. A second conductive layer is formed on the insulation layer and the first conductive layer and the first and second conductive layers and the insulation layer are patterned to form a first gate structure and a second gate structure in the NMOS region and the PMOS region, respectively.
