Thyristor semiconductor device comprising an anode region, a first base region and a second base region having opposite types of conductivity, and a cathode region, all superimposed along a vertical axis.

Thyristor semiconductor device and corresponding manufacturing method

A device includes, within a layer of silicon on insulator, a central semiconductor zone including a central region having a first type of conductivity, two intermediate regions having a second type of conductivity opposite to that of the first one, respectively disposed on either side of and in contact with the central region in order to form two PN junctions, two semiconductor end zones respectively disposed on either side of the central zone, each end zone comprising two end regions of opposite types of conductivity, in contact with the adjacent intermediate region, the two end regions of each end zone being mutually connected electrically in order to form the two terminals of the device.

Bidirectional semiconductor device for protection against electrostatic discharges, usable on silicon on insulator

A triggerable bidirectional semiconductor device has two terminals and at least one gate. The device comprises, within a layer of silicon on insulator, a central semiconductor zone incorporating the at least one gate and comprising a central region having a first conductivity type, two intermediate regions having a second conductivity type respectively arranged on either side of and in contact with the central region, two semiconductor end zones respectively arranged on either side of the central zone, each end zone comprising two end regions having opposite types of conductivity, in contact with the adjacent intermediate region, the two end regions of each end zone being mutually connected electrically in order to form the two terminals of the device.
