Abstract: An integrated circuit die includes a substrate having a first layer of semiconductor material, a layer of dielectric material on the first layer of semiconductor material, and a second layer of semiconductor material on the layer of dielectric material. An extended channel region of a transistor is positioned in the second layer of semiconductor material, interacting with a top surface, side surfaces, and potentially portions of a bottom surface of the second layer of semiconductor material. A gate dielectric is positioned on a top surface and on the exposed side surface of the second layer of semiconductor material. A gate electrode is positioned on the top surface and the exposed side surface of the second layer of semiconductor material.
