Abstract:
An exemplary aspect of the present invention is an SRAM including: a first gate electrode that constitutes a first load transistor; a second gate electrode that extends in a longitudinal direction of the first gate electrode so as to be spaced apart from the first gate electrode, and constitutes a first drive transistor; a third gate electrode that extends in parallel to the first gate electrode, and constitutes a second load transistor; a first p-type diffusion region that is formed so as to intersect with the third gate electrode, and constitutes the second load transistor; and a first shared contact formed over the first and second gate electrodes and the first p-type diffusion region. The first p-type diffusion region extends to the vicinity of a first gap region between the first and second gate electrodes, and is not formed in the first gap region.
