    Abstract: PROBLEM TO BE SOLVED: To provide a technique for forming a double gate/double channel MOSFET structure which has excellent short channel characteristics and a channel length of below 0.05 μm, and to provide the double gate/double channel MOSFET structure itself.
    SOLUTION: This technique for manufacturing a MOSFET device which has a double gate/double channel structure uses a damascene process. A gate is located at each side of a silicon film which is about 80 nm or below in vertical thickness and positioned in a gate region. The silicon film functions as the vertical channel region of the structure and interconnects a diffusion region adjacent to the gate region. Due to its double channel feature, the current of this device is twice as large as that of a conventional plane MOSFET of the same physical width.
