Publication number: 20230261040Abstract: A semiconductor device includes a substrate layer having a floating base region of a first conductivity type. A first well of a second conductivity type and the floating base region form a first pn junction. A first conductive structure is electrically connected to the first well. A barrier region of the second conductivity type and the floating base region form an auxiliary pn junction. A second conductive structure is electrically connected to the floating base region through a rectifying structure. A pull-down structure is configured to produce a voltage drop between the barrier region and the second conductive structure, when charge carriers cross the auxiliary pn junction.Type: ApplicationFiled: February 16, 2023Publication date: August 17, 2023Inventors: Christian Schippel, Dirk Priefert, Felix Simon Winterer, Remigiusz Viktor Boguszewicz
