    摘要: 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.

    摘要: A semiconductor substrate of a first conductivity type is coated with a semiconductor layer of a second conductivity type. A buried region of the second conductivity type is formed an interface between the semiconductor substrate and the semiconductor layer. First and second wells of the first conductivity type are provided in the semiconductor layer. A second region of the second conductivity type is formed in the first well. A third region of the second conductivity type is formed in the second well. The first well, the semiconducting layer, the second well and the third region form a first lateral thyristor. The second well, the semiconductor layer, the first well and the second region form a second lateral thyristor. The buried region and semiconductor substrate form a zener diode which sets the trigger voltage for the lateral thyristors.

    摘要: A method for manufacturing electronic chips includes forming, on the side of a first face of a semiconductor substrate, in and on which a plurality of integrated circuits has been formed beforehand, metallizations coupling contacts of adjacent integrated circuits to one another. The method further includes forming, on the side of the first face of the substrate, first trenches extending through the first face of the substrate and laterally separating the adjacent integrated circuits. The first trenches extend through the metallizations to form at least a portion of metallizations at each of the adjacent circuits.
