Abstract:
1. A semiconductor device comprising: a plurality of active regions formed in a semiconductor substrate, the plurality of active regions being arranged in a first direction which is parallel to a surface of the semiconductor substrate; a first element isolating region formed in the semiconductor substrate, the first element isolating region electrically isolating adjacent active regions out of the plurality of active regions from each other; and a plurality of gate electrodes formed on the surface of the semiconductor substrate so that the plurality of the gate electrodes extends over the plurality of active regions respectively, the plurality of gate electrodes being arranged in the first direction; wherein the first element isolating region includes, between the adjacent active regions, a first region extending in a second direction which is parallel to the surface and orthogonal to the first direction and a second region extending in a direction which is parallel to the surface and intersects the first region, one gate electrode of adjacent gate electrodes out of the plurality of gate electrodes has a first edge side which includes a first overlap part placed on the second region, and another gate electrode of the adjacent gate electrodes has a second edge side which faces the first edge side and includes a second overlap part placed on the second region.
