Abstract
In some embodiments, the present disclosure relates to a method that includes receiving an initial layout design for a circuit schematic. The initial layout design includes a first gate electrode, a second gate electrode, and a third gate electrode arranged over a continuous fin. A first source/drain region is arranged between the first gate electrode and dummy gate electrode, and a second source/drain region is arranged between the second gate electrode and the dummy gate electrode. The method further includes determining if at least one of the first or second source/drain regions corresponds to a drain in the circuit schematic, and modifying the initial layout design to increase a dummy threshold voltage associated with the dummy gate electrode when the at least one of the first or second source/drain regions corresponds to the drain in the circuit schematic to provide a modified layout design.
