Abstract :
We have investigated the effect of shallow trench isolation (STI) induced mechanical x-stress (in the direction of channel length) effect on transistor channel width. STI x-stress has less effect on narrow width NMOS transistor for both threshold voltage (Vt) and drain current (Id). For narrow width PMOS transistor, STI x-stress has higher effect on Id. PMOS Vt is not affected by STI x-stress.
