    Abstract: A FinFET includes a fin formed on an insulating layer and a first gate material layer formed proximate to sides of the fin. The FinFET further includes a protective layer formed above the first gate material layer and the fin, and a second gate material layer formed above the protective layer and the fin. The second gate material layer may be formed into a gate for the fin that may be biased independently of gate(s) formed from the first gate material layer, thus providing additional design flexibility in controlling the potential in the fin during on/off switching of the FinFET.

    Abstract: A double-gate vertical MOSFET transistor is described along with an associated fabrication method. The MOSFET transistor is configured with separate gates on each side of a vertical source-drain channel that is capped by an insulation layer. The fabrication process generally comprises forming a silicon-insulator stack having a silicon fin (channel) capped with insulation. The opposing ends of the silicon-insulator stack being configured with areas capable of receiving source and drain contacts. The vertical surfaces of the silicon fin are insulated prior to the formation of gate electrodes adjacent the two opposing sides of the silicon-insulator stack. By way of example, the gate electrodes are formed by depositing a thick layer of conductive gate material over the substrate and then removing the adjoining upper portion, such as by polishing. Portions of each gate electrode are configured with areas capable of receiving a gate contact.
