Abstract
Semiconductor devices whose current characteristics can be prevented from varying even if a phase shift mask is used for patterning gate electrodes of MISFETs, and a manufacturing method thereof are disclosed. According to one aspect of the present invention, there is provided a semiconductor device comprising a first transistor including a first gate electrode provided above a semiconductor substrate, and a first source and a first drain provided in the semiconductor substrate, a second transistor arranged to be adjacent to the first transistor, and including a second gate electrode provided above the semiconductor substrate in parallel with the first gate electrode, and a second source and a second drain provided in the semiconductor substrate, and a third gate electrode provided between the first transistor and the second transistor and in parallel with the first and second gate electrodes.
