ABSTRACT:
A structure of a capacitor circuit in accordance with the present invention comprises a plurality of capacitors formed on a semiconductor or conductor substrate in a manner in which insulating films and electrodes are provided alternately. This structure is characterized in that: there are provided a first capacitor and a second capacitor adjacent to each other; the first capacitor and the second capacitor comprise, respectively, first electrodes formed on the substrate through the first insulating film, second electrodes formed on the first electrodes through the second insulating film and third electrodes formed on the second electrodes through the third insulating film, the third electrode of the first capacitor being connected to the second electrode of the second capacitor.
