Abstract
The invention concerns a low-capacity vertical diode designed to be mounted by a front surface made in a semiconductor substrate (), comprising a first zone projecting relative to the surface of the substrate including at least a semiconductor layer () doped with a type of conductivity opposite to that of the substrate, the upper surface of the semiconductor layer bearing a first solder bump (). The diode comprises a second zone including on the substrate a thick strip conductor () bearing at least second solder bumps (), said first and second solder bumps defining a plane parallel to the substrate plane.
