Abstract:
A semiconductor device on a substrate comprising:at least one gate, at least the one gate including a first edge and a second edge and a base; a tunneling barrier disposed along the base of at least the one gate, between the substrate and at least the one gate; and a source for at least the one gate, the source being along to the first edge of at least the one gate, at least the one gate, the source or both being configured such that the source does not substantially overlap at least the one gate at the base of at least the one gate; wherein the source includes at least one dopant and wherein during fabrication, semiconductor device further comprises: a doping spacer for at least the one gate, the doping spacer along at least the first edge of at least the one gate, the doping spacer having a width, the width being sufficiently large to prevent at least the one dopant for the source from overlapping at least the one gate at the base of at least the one gate when at least the one dopant is provided after the doping spacer.
