Abstract
This electronic semiconductor device for protecting integrated circuits against electrostatic discharges has a minimal bulk, can withstand high damaging voltages and be produced during the same production phases as the integrated circuit to be protected. The device comprises a pair of diodes connected back to back, arranged between an input of the integrated circuit to be protected and the ground line, with the cathodes connected together and formed by a single semiconductor layer and the anodes formed in a single process phase by employing top-bottom production techniques.
