Patent ID: 7187026

Claim:
A semiconductor device comprising: a semiconductor substrate; a capacitor structure formed above the semiconductor substrate and comprising: a first electrode, a second electrode provided below the first electrode, a third electrode provided below the second electrode, a first dielectric film provided between the first electrode and the second electrode, and a second dielectric film provided between the second electrode and the third electrode; an insulating film covering the capacitor structure and having a first hole reaching the first electrode, a second hole reaching the second electrode, and a third hole reaching the third electrode; a first conductive connection electrically connecting the first electrode and the third electrode and having portions buried in the first and third holes; and a second conductive connection formed separately from the first conductive connection and having a portion buried in the second hole, wherein a first outer end of the second electrode extends in a first direction parallel to a main surface of the semiconductor substrate and is entirely positioned outside the first electrode, and a second outer end of the second electrode extends in a second direction opposite the first direction and is entirely positioned outside the first electrode, a first outer end of the third electrode is entirely positioned outside the second electrode and extends in the first direction parallel to the main surface of the semiconductor substrate, and a second outer end of the third electrode is entirely positioned outside the second electrode and extends in the second direction.
