Abstract:
1. A double gate germanium metal-oxide semiconductor field-effect transistor (MOSFET), comprising: a germanium fin; a cover layer formed on an upper surface of the germanium fin; a first gate formed adjacent a first side of the germanium fin and comprising a first layer of material having an upper surface that is substantially co-planar with an upper surface of the cover layer and a lower surface that is substantially co-planar with a lower surface of the germanium fin, the first layer having a substantially uniform thickness that extends laterally from the first side of the germanium fin; and a second gate formed adjacent a second side of the germanium fin opposite the first side and comprising a second layer of material having an upper surface that is substantially co-planar with the upper surface of the cover layer and a lower surface that is substantially co-planar with the lower surface of the germanium fin, the second layer having a substantially uniform thickness that extends laterally from the second side of the germanium fin, wherein each of the first and second gates comprise a thickness ranging from approximately 1200 Å to 1500 Å.
