Isolation structure for esd device

Номер: US20130119433A1
Автор: Chun-Kai Wang

Among other things, an electrostatic discharge (ESD) device is provided. The ESD device comprises a dielectric isolation structure that is formed between an emitter and a collector of the ESD device. During an ESD event, current flows from the emitter, substantially under the dielectric isolation structure, to the collector, to protect associated circuitry. The dielectric isolation structure is formed to a depth that is less than a depth of at least one of the emitter or the collector, or doped regions thereof, thereby decreasing a length of a current path from the emitter to the collector, because the current is not obstructed by the dielectric isolation structure. Accordingly, the ESD device can carry higher current during the ESD event because the shorter current path has less resistance than a longer path that would otherwise be traveled if the dielectric isolation structure was not formed at the shallower depth.

A full bridge rectifier includes four bipolar transistors, each of which has an associated parallel diode. A first pair of inductors provides inductive current splitting and thereby provides base current to/from one pair of the bipolar transistors so that the collector-to-emitter voltages of the bipolar transistors are low. A second pair of inductors similarly provides inductive current splitting to provide base current to/from the other pair of bipolar transistors. In one embodiment, all components are provided in a four terminal full bridge rectifier module. The module can be used as a drop-in replacement for a conventional four terminal full bridge diode rectifier. When current flows through the rectifier module, however, the voltage drop across the module is less than one volt.
