    摘要: In one embodiment, a semiconductor device includes a semiconductor substrate having a lower layer and an upper layer overlying the lower layer. The upper layer is arranged and structured to form first and second active regions that are spaced apart from each other and protrude from an upper surface of the lower layer. A third active region of a bridge shape is distanced vertically from the upper surface of the lower layer and connects the first and second active regions. The device further includes a gate electrode, which is formed with a gate insulation layer surrounding the third active region, so that the third active region functions as a channel.

    摘要: According to some embodiments, a fin type active region is formed under an exposure state of sidewalls on a semiconductor substrate. A gate insulation layer is formed on an upper part of the active region and on the sidewalls, and a device isolation film surrounds the active region to an upper height of the active region. The sidewalls are partially exposed by an opening part formed on the device isolation film. The opening part is filled with a conductive layer that partially covers the upper part of the active region, forming a gate electrode. Source and drain regions are on a portion of the active region where the gate electrode is not. The gate electrode may be easily separated and problems causable by etch by-product can be substantially reduced, and a leakage current of channel region and an electric field concentration onto an edge portion can be prevented.

    摘要: Provided is a double gate field effect transistor and a method of manufacturing the same. The method of manufacturing the double gate field effect transistor comprises forming as many fins as required by etching a silicon substrate, masking the resultant product by an insulating material such as silicon nitride, forming trench regions for device isolation and STI film by using the silicon nitride mask, forming gate oxide films on both faces of the fins after removing the hard mask, and forming a gate line. As such, unnecessary channel formation under the silicon oxide film, when a voltage higher than a threshold voltage is applied to the substrate, is prevented by forming a thick silicon oxide film on the substrate on which no protruding fins are formed.
