  • Patent number: 9953968
    Abstract: An integrated circuit having an ESD protection structure is described. One embodiment includes a circuit section interconnected with a first terminal and with a second terminal and being operable at voltage differences between the first terminal and second terminal of greater than +10 V and less than ?10 V. The integrated circuit additionally includes an ESD protection structure operable to protect the circuit section against electrostatic discharge between the first terminal and the second terminal. The ESD protection structure is operable with voltage differences between the first and second terminals of greater than +10 V and less than ?10 V without triggering. The ESD protection structure is electrically and optically coupled to a photon source such that photons emitted by the photon source upon ESD pulse loading are absorbable in the ESD protection structure and an avalanche breakdown is initiatable by electron-hole pairs generated by the absorbed photons.
