Patent ID: 11621346

Abstract:
A vertical metal oxide semiconductor field effect transistor (MOSFET) and a method for forming a vertical MOSFET is presented. The MOSFET comprises: a top contact; a bottom contact; a nanowire (602) forming a charge transport channel between the top contact and the bottom contact; and a wrap-around gate (650) enclosing the nanowire (602) circumference, the wrap-around gate (650) having an extension spanning over a portion of the nanowire (602) in a longitudinal direction of the nanowire (602), wherein the wrap-around gate (650) comprises a gate portion (614) and a field plate portion (616) for controlling a charge transport in the charge transport channel, and wherein the field plate portion (616) is arranged at a first radial distance (636) from the center of the nanowire (602) and the gate portion (614) is arranged at a second radial distance (634) from the center of the nanowire (602); characterized in that the first radial distance (636) is larger than the second radial distance (634).
