    摘要： A double gate MOS transistor includes a substrate active region defined in a semiconductor substrate and a transistor active region located over the substrate active region and overlapped with the substrate active region. At least one semiconductor pillar penetrates the transistor active region and is in contact with the substrate active region. The semiconductor pillar supports the transistor active region so that the transistor active region is spaced apart from the substrate active region. At least one bottom gate electrode fills a space between the transistor active region and the substrate active region. The bottom gate electrode is insulated from the substrate active region, the transistor active region and the semiconductor pillar. At least one top gate electrode crosses over the transistor active region and has at least one end that is in contact with a sidewall of the bottom gate electrode. The top gate electrode overlaps with the bottom gate electrode and is insulated from the transistor active region. Methods of fabricating such transistors are also provided.

    摘要： Integrated circuit field effect transistor devices include a substrate having a surface and an active channel pattern on the surface. The active channel pattern includes channels that are stacked upon one another and are spaced apart from one another to define at least one tunnel between adjacent channels. A gate electrode surrounds the channels and extends through the at least one tunnel. A pair of source/drain regions also is provided. Integrated circuit field effect transistors are manufactured, by forming a pre-active pattern on a surface of a substrate. The pre-active pattern includes a series of interchannel layers and channel layers stacked alternately upon each other. Source/drain regions are formed on the substrate at opposite ends of the pre-active pattern. The interchannel layers are selectively removed to form tunnels. A gate electrode is formed in the tunnels and surrounding the channels.
