Abstract

An integrated circuit configuration, in particular for igniting a restraint device of a motor vehicle, has a capacitor and an ignition element. In this case, a porous region of a semiconductor layer forms a capacitor electrode, which is isolated from a further semiconductor layer by a dielectric layer. The further semiconductor layer being configured as a further capacitor electrode. The further semiconductor layer has a region that is tapered in its cross-section and serves as an ignition element electrically connected to the capacitor.
