Patent ID: 8080841

Claim:
A semiconductor device comprising: a semiconductor substrate; a plurality of transistors connected in series, a first transistor in the plurality of transistors having a first diffusion region and a second diffusion region arranged in the semiconductor substrate; an insulating film columnar body arranged above the semiconductor substrate and having a first side which is inclined to a top surface of the substrate by a first inclination angle that is greater than 0 degrees and less than 90 degrees; and a first memory cell including a first electrode arranged on the first side of the insulating film columnar body and connected to the first diffusion region via a first contact plug, a first ferroelectric film arranged on the first electrode and inclined to the top surface of the substrate by the first inclination angle, and a second electrode arranged on the first ferroelectric film, connected to the second diffusion region via a second contact plug, and inclined to the top surface of the substrate by the first inclination angle.
