Abstract:
A semiconductor device comprising:a silicon substrate;an insulating film formed on the silicon substrate;a first lower electrode disposed on the insulating film, the first lower electrode extending along a first direction and having a stripe-shaped plan configuration having a size in the first direction being longer than that in a second direction perpendicular to the first direction;second upper electrodes disposed above the first electrode opposite thereto and having a plan configuration in which the size thereof in the first and second directions are shorter than those of the first electrode, and the size thereof in the first and second directions are equal to each other or the size in the first direction is shorter than the size in the second direction;a ferroelectric layer serving as a capacitance insulating film disposed between the first electrode and the second electrodes,wherein the first and second electrodes and the ferroelectric layer therebetween constitute ferroelectric capacitors; anda contact hole disposed on a surface of each second electrode, each said contact hole being shifted from the center of said surface to one side along the first direction of the first electrode.
