Abstract
The capacitance between the gate electrode and the source/drain regions of a semiconductor device is reduced by forming source and drain regions that are recessed a prescribed depth below the main surface of the semiconductor substrate. Sidewall spacers and a silicide layer are subsequently formed on the gate electrode stack. The resulting semiconductor device exhibits reduced capacitance between the gate electrode and the source/drain regions, while maintaining circuit reliability.
