Abstract
The semiconductor device comprises a semiconductor substrate (SB) having locally at least one zone (ZL) terminating in the surface of the substrate and entirely bordered, along its lateral edges and its bottom, by an insulating material so as to be completely isolated from the rest of the substrate. The horizontal isolating layer may be a layer of constant thickness or a crenellated layer.
