In the case of a semiconductor igniter, particularly for the gas generator of a protection system for vehicle occupants, consisting of a semiconductor layer which is arranged on a carrier with the insertion of a thermal insulation layer, is connected at the end side to electric contact areas and during the current passage in the ignition path range heats up in an ignition-triggering manner, while maintaining a high ignition efficiency, a mechanically secure linking of the semiconductor layer to the carrier is achieved in that the thermal insulation layer is limited to the ignition path range of the semiconductor layer and the semiconductor layer is connected directly with the carrier at its end sections kept free of the thermal insulation layer.

[ What is claimed is:] [1.]1. A semiconductor igniter, comprising:a semiconductor layer which is arranged on a carrier;a thermal insulation layer formed in said carrier, the semiconductor layer having end sections with each of said end sections being connected to respective electric contact areas and, during passage of a current in an ignition path range, said semiconductor layer heats up in an ignition-triggering manner,wherein the thermal insulation layer is limited to the ignition path range of the semiconductor layer and, on each of said end sections, the semiconductor layer is kept free of the thermal insulation layer, said semiconductor layer being fixedly connected with the carrier.
