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.

A method of forming multiple structures in a semiconductor device includes depositing a film over a conductive layer, etching a trench in a portion of the film and forming adjacent the sidewalls of the trench. The film may then be etched, followed by an of the conductive layer to form the structures.
