摘要
A structure and a method of manufacturing a double-gate metal oxide semiconductor transistor includes forming a laminated structure having a single crystal silicon channel layer and insulating oxide and nitride layers on each side of the single crystal silicon channel, forming openings in the laminated structure, forming drain and source regions in the openings, doping the drain and source regions, forming a mask over the laminated structure, removing portions of the laminated structure not protected by the mask, removing the mask and the insulating oxide and nitride layers to leave the single crystal silicon channel layer suspended from the drain and source regions, forming an oxide layer to cover the drain and source regions and the channel layer, and forming a double-gate conductor over the oxide layer such that the double-gate conductor includes a first conductor on a first side of the single crystal silicon channel layer and a second conductor on a second side of the single crystal silicon channel layer.
