Abstract
A monolithic integrated circuit has a plurality of capacitors forming a bypass to ground, each of the capacitors being composed of two conductive coatings layers which are arranged on a substrate and separated from one another by a dielectric layer, a lower one of the coatings located on the substrate under the dielectric layer contacting with a ground conductor on an opposite substrate side, and the lower coatings of the capacitors being connected with one another, while only one upper coating which belongs to a capacitor is contacted through a through contacting in the substrate with the ground conductor.
