Abstract

An integrated circuit configuration has both an ignition resistor and a control circuit that controls a current flow through the ignition resistor. A region of a semiconductor layer that electrically connects the integrated components is used as the ignition resistor. An electrically conductive layer for making electrical contact with the control circuit and a semiconductor layer for the components has a cutout in the region of the ignition resistor and ignition material is in direct contact with the integrated circuit configuration at the ignition region.
