Abstract
An insulating wall of a second conductivity type intended for separating elementary components formed in different wells of a semiconductive layer of a first conductivity type, a component located in one at least one of the wells being capable of operating with a high current density. The insulating wall includes at least two elementary insulating walls separated by a portion of the wafer material and, in operation, this portion is connected to a reference potential.
