DISPOSITIF DE PROTECTION CONTRE LES DECHARGES ELECTROSTATIQUES POUR COMPOSANTS MICROELECTRONIQUES SUR SUBSTRAT DU TYPE SOI

摘要

The invention relates to a device (25) that protects an electronic component from electrostatic discharges. Said device is created in the semiconductor layer of a substrate covering an insulating layer. The device is joined to a contact pad (21-24) that pertains to said component and is to be protected in order to divert any possible electrostatic discharge. The invention is characterized in that the device (25) includes at least one Zener diode that is joined to the contact pad for direct polarization.
