Abstract:
In this paper we present experimental and simulation results on planar-doped-barrier MOSFETs (PDBFETs) and show the advantages that arise from the channel delta doping. Early and higher magnitude of velocity overshoot, suppression of avalanche multiplication, reduced hot-carrier problems are some of the advantages offered by PDBFETs over the conventional homogeneously doped MOSFETs in the sub 100 nm regime. Our low-temperature characterizations show clear ballistic transport in the fabricated 85 nm channel MOSFETs.
