Abstract
A monolithic component including, in an N-type lightly-doped substrate of a semiconductor wafer, two portions separated by a P-type insulating wall. A first portion of the two portions includes a high voltage lateral component, a layer of which substantially corresponds to the thickness of the wafer. The second portion includes logic circuit components. A rear surface of the substrate includes a P-type layer coated with a metallization. The insulating wall is in electrical contact with a low voltage terminal of the high voltage lateral component, such as the gate region of a thyristor. The logic portion includes at least one vertical component.
