    摘要: A field effect transistor (FET) is formed on a silicon substrate, with a nitride gate insulator layer being deposited on the substrate and an oxide gate insulator layer being deposited on the nitride layer to insulate a gate electrode from source and drain regions in the substrate. The gate material is then removed to establish a gate void, and spacers are deposited on the sides of the void such that only a portion of the oxide layer is covered by the spacers. Then, the unshielded portion of the oxide layer is removed, thus establishing a step between the oxide and nitride layers that overlays the source and drain extensions under the gate void to reduce subsequent capacitive coupling and charge carrier tunneling between the gate and the extensions. The spacers are removed and the gate void is refilled with gate electrode material.

    摘要: A double gate metal-oxide semiconductor field-effect transistor (MOSFET) includes a fin, a first gate and a second gate. The first gate is formed on top of the fin. The second gate surrounds the fin and the first gate. In another implementation, a triple gate MOSFET includes a fin, a first gate, a second gate, and a third gate. The first gate is formed on top of the fin. The second gate is formed adjacent the fin. The third gate is formed adjacent the fin and opposite the second gate.

    摘要: A method of fabricating an integrated circuit with ultra-shallow source/drain junctions utilizes a dummy or sacrificial gate structure. Dopants are provided through the openings associated with sacrificial spacers to form the source and drain extensions. The openings can be filled with spacers The process can be utilized for P-channel or N-channel metal oxide field semiconductor effect transistors (MOSFETS).
