Patent ID: 7138670

Claim:
A semiconductor device comprising: a semiconductor substrate; an insulation layer formed on the semiconductor substrate; a plurality of first electrodes formed on the insulation layer and spaced from one another by an interval, S; an insulation film covering the first electrodes; and a plurality of second electrodes formed on the insulation film and spaced from one another by another interval, each second electrode including an intermediate portion filling the space between two adjacent electrodes and two edge portions respectively laid above the two adjacent first electrodes in an overlapping manner, wherein thickness, t 1 , of the insulation film, thickness, t 2 , of each edge portion of the second electrode, and the interval S between the first electrodes satisfy the expression of S <(2 t 1+2 t 2) wherein each of the first electrodes includes a portion that locally narrows space form an adjacent one of the first electrodes, wherein each of the second electrodes includes an upper surface connected to a wire by a contact and the contact is connected to a portion of the upper surface of the second electrode, the portion being laid over the locally narrowed portion of the first electrodes.
