US 6,583,496 B2 · Single-control monolithic component for a composite bridge

Abstract

A monolithic component including two thyristors of a composite bridge connected to an A.C. voltage terminal by a common terminal corresponding to a common rear surface metallization forming an electrode of opposite biasing of each thyristor. An isolating wall separates a substrate in two portions, a first portion includes on its lower surface side an anode region and on its upper surface side a cathode region, the second portion includes on its lower surface side a cathode region and on its upper surface side an anode region. The isolating wall surrounding each of the components extending towards the main electrode on the side which carries no common metallization and including in this extended region an N-type area, the two areas being connected together to a common control terminal.

Dependent claims

A monolithic component including a first thyristor and a second thyristor, the component comprising:

a common contact on one surface of the component conductively connected to the anode of the first thyristor and the cathode of the second thyristor;
an isolation wall separating the first and the second thyristor, the isolation wall of a same conductivity type and contiguous with the anode of the first thyristor as well as a layer of the second thyristor immediately adjacent to the cathode of the second thyristor;
at least one gate contact on a surface opposite to the common contact which controls both the first and second thyristor;
at least one region disposed beneath and conductively coupled to the at least one gate contact, forming at least one diode junction with the isolating wall.
