Abstract
The present invention relates to an isolating wall for separating elementary components formed in different wells, a component located in at least one of the wells being capable of operating with a high current density. The isolating wall exhibits in its median portion a concentration of carriers higher than 10.sup.16 atoms/cm.sup.3. Preferably, the width of the openings from which the dopant diffusions are formed in the upper and lower surfaces of the substrate is higher than 1.3 times the half-thickness of the substrate.
