Claim:
1. A Fin field-effect transistor (FET) (FinFET)-based circuit, comprising: a semiconductor substrate; a Fin formed from the semiconductor substrate; a first FinFET corresponding to the Fin; a second FinFET corresponding to the Fin; a gate region disposed between the first FinFET and the second FinFET; and a self-aligned single diffusion break (SDB) isolation structure formed in the Fin between the first FinFET and the second FinFET and self-aligned with the gate region, wherein the self-aligned SDB isolation structure electrically isolates the first FinFET and the second FinFET and applies stress to a first channel corresponding to the first FinFET and to a second channel corresponding to the second FinFET.
