Abstract:
1. A method of forming a semiconductor structure comprising: providing a semiconductor-on-insulator substrate having a top semiconductor layer having a doping of a first conductivity type; forming a gate conductor on said top semiconductor layer; forming a source side halo region and drain side halo region, each having a doping of said first conductivity type, in said top semiconductor layer; forming at least one gate spacer on said gate conductor; and forming a deep source region and a deep drain region, each having a doping of a second conductivity type, in said top semiconductor layer by angled ion implantation, wherein said second conductivity type is the opposite of said first conductivity type, said deep source region is formed offset away from an edge of said at least one gate spacer and does not contact said at least one gate spacer, and wherein said deep drain region is formed directly below said at least one gate spacer and directly contacts said at least one gate spacer.
