    摘要: A method is described for selectively treating the properties of a gate dielectric near corners of the gate without altering the gate dielectric in a center region of a gate channel. The method includes providing a structure having a gate opening and depositing a layer of dielectric with a high dielectric constant on a bottom surface and side walls of the gate opening. The corner regions of the high dielectric constant layer formed adjacent to the bottom surface and the side walls of the gate opening are selectively treated without altering the center region of the high dielectric constant layer formed at the bottom surface of the gate opening.

    摘要: A nonplanar semiconductor device and its method of fabrication is described. The nonplanar semiconductor device includes a semiconductor body having a top surface opposite a bottom surface formed above an insulating substrate wherein the semiconductor body has a pair laterally opposite sidewalls. A gate dielectric is formed on the top surface of the semiconductor body on the laterally opposite sidewalls of the semiconductor body and on at least a portion of the bottom surface of semiconductor body. A gate electrode is formed on the gate dielectric, on the top surface of the semiconductor body and adjacent to the gate dielectric on the laterally opposite sidewalls of semiconductor body and beneath the gate dielectric on the bottom surface of the semiconductor body. A pair source/drain regions are formed in the semiconductor body on opposite sides of the gate electrode.
