An upper surface of the porous silicon ring is only in contact with the substrate of the first conductivity type. The insulating porous silicon ring penetrates into the substrate down to a depth greater than a thickness of the well. The porous silicon ring is produced by forming a doped well in a first surface of a doped substrate, placing that first surface of the substrate into an electrolytic bath, and circulating a current between an opposite second surface of the substrate and the electrolytic bath.
