Abstract
Embodiments of the invention provide a transistor with stepped source and drain regions. The stepped regions may provide significant strain in a channel region while minimizing current leakage. The stepped regions may be formed by forming two recesses in a substrate to result in a stepped recess, and forming the source/drain regions in the recesses.
