Abstract:
An electronic device formed on a chip of semiconductor material comprising:a substrate having a first type of conductivity and a plurality of surfaces, one of whose surfaces is a bottom surface of the chip,a layer having a second type of conductivity formed on the substrate and having a surface which is a top surface of the chip,at least one first region having the first type of conductivity, that extends into the layer from the top surface,a termination structure comprising:a first termination region having the first type of conductivity, that extends into the layer from the top surface and is shaped in such a way that it surrounds the at least one first region,a first electrode in contact with the first termination region,a second electrode in contact with the layer on the top surface, shaped in the form of a frame close to the edge of the chip,a third electrode in contact with the bottom surface of the chip and connected electrically to the second electrode,a second termination region having the first type of conductivity, which extends into the layer from the top surface, and shaped in the form of a frame surrounding the fifth electrode,a fourth electrode in contact with the at least one first region and connected electrically to the first electrode, anda fifth electrode in contact with the layer on the top surface along a path that extends substantially parallel to at least part of an edge of the first termination region and connected electrically to the second electrode.
