    摘要: Methods of forming integrated circuit devices include forming a gate electrode on a substrate and forming a nitride layer on a sidewall and upper surface of the gate electrode. The nitride layer is then anisotropically oxidized under conditions that cause a first portion of the nitride layer extending on the upper surface of the gate electrode to be more heavily oxidized relative to a second portion of the nitride layer extending on the sidewall of the gate electrode. A ratio of a thickness of an oxidized first portion of the nitride layer relative to a thickness of an oxidized second portion of the nitride layer may be in a range from about 3:1 to about 7:1.

    摘要: A semiconductor device may include a semiconductor substrate having first and second regions. A first gate structure on the first region of the semiconductor substrate may include a metal oxide dielectric layer on the first region of the semiconductor substrate and a first conductive layer on the metal oxide dielectric layer. First and second source/drain regions of a first conductivity type may be provided in the first region of the semiconductor substrate on opposite sides of the first gate structure. A second gate structure on the second region of the semiconductor substrate may include a silicon oxide based dielectric layer and a second conductive layer on the silicon oxide based dielectric layer. First and second source/drain regions of a second conductivity type may be provided in the second region of the semiconductor substrate on opposite sides of the second gate structure, wherein the first and second conductivity types are different. Related methods are also discussed.
