Abstract
The present disclosure provides an electronic device that includes a substrate. The substrate includes a well and a peripheral insulating wall laterally surrounding the well. At least one lateral bipolar transistor is formed in the well, and the at least one transistor has a base region extending under parallel collector and emitter regions. The peripheral insulating wall is widened in a first direction, parallel to the collector and emitter regions, so that the base region penetrates into the peripheral insulating wall.
