Electrostatic Discharge Protection Element and Electrostatic Discharge Protection Chip and Method of Producing the Same
Abstract:
An electrostatic discharge (ESD) protection element includes a collector area, a first barrier area, a semiconductor area, a second barrier area and an emitter area. The collector area has a first conductivity type. The first barrier area borders on the collector area and has a second conductivity type. The semiconductor area borders on the first barrier area and is an intrinsic semiconductor area, or has the first or second conductivity type and a dopant concentration which is lower than a dopant concentration of the first barrier area. The second barrier area borders on the semiconductor area and has the second conductivity type and a higher dopant concentration than the semiconductor area. The emitter area borders on the second barrier area and has the first conductivity type.
