Abstract
A transistor device includes a gate structure positioned above a semiconductor substrate, and spaced-apart sidewall spacers positioned above the substrate and adjacent sidewalls of the gate structure. An internal sidewall surface of each of the spaced-apart sidewall spacers includes an upper sidewall surface portion and a lower sidewall surface portion positioned between the upper sidewall surface portion and a surface of the substrate, wherein a first lateral width between first upper ends of the upper sidewall surface portions is greater than a second lateral width between second upper ends of the lower sidewall surface portions.
