Abstract
A capacitor that includes a substrate; a capacitor formation region in which one or more trenches are formed; a dummy region located between the capacitor formation region and an end of the substrate; a first electrode formed inside the one or more trenches to cover the capacitor formation region, and a dielectric film; a second electrode that covers the capacitor formation region and has a different potential from the first electrode; and an extended portion that formed in the dummy region. Moreover, the extended portion forms a recess or a protrusion on the substrate in a path from the second electrode to the end portion of the substrate.
