    Abstract: Methods for forming FinFET source/drain regions with a single reticle and the resulting devices are disclosed. Embodiments may include forming a first fin and a second fin above a substrate, forming a gate crossing over the first fin and the second fin, removing portions of the first fin and the second fin on both sides the gate, forming silicon phosphorous tops on the first fin and the second fin in place of the portions, removing the silicon phosphorous tops on the first fin, and forming silicon germanium tops on the first fin in place of the silicon phosphorous tops.
