Patent ID: 8013665

Claim:
A semiconductor device including a boosting circuit, the boosting circuit comprising: a plurality of rectifying elements connected in series between an input terminal portion and an output terminal portion of the boosting circuit, each of the rectifying elements including an input portion and an output portion, with an input portion of a first one of the rectifying elements being connected to the input terminal portion; and a plurality of capacitor elements each including a first electrode, a second electrode, and an insulating film interposed between the first electrode and the second electrode, wherein the first electrode of a first one of the plurality of capacitor elements is connected to an output portion of the first one of the plurality of rectifying elements, wherein the first electrode of a k-th one of the plurality of capacitor elements is connected to an output portion of a k-th one of the rectifying elements and to an input portion of a (k+1)th one of the rectifying elements (where k is an integer of 2≦k≦(n−1)), wherein only the first one of the plurality of capacitor elements does not comprise a semiconductor film as the first electrode and the second electrode, and wherein the first electrode of at least another one of the plurality of capacitor elements comprises a first conductive film and the second electrode of at least another one of the plurality of capacitor elements comprises a semiconductor film.
