A diode including: first and second doped semi-conductor portions forming a p-n junction, a first part of the first portion being arranged between a second part of the first portion and the second portion; dielectric portions covering side walls of the second portion and the first part of the first portion; a first electrode arranged against outer side walls of the dielectric portions and against side walls of the second part of the first portion, electrically connected to the first portion only by contact with said side walls, and passing through the entire thickness of the first portion; a second optically reflecting electrode electrically connected to the second portion such that the second portion is arranged between the second electrode and the first portion.

Microelectronic diode with optimised active surface

A device including a plurality of interconnected concentric coplanar diodes.

Device comprising a plurality of diodes

A diode including a vertical stack of first and second semiconductor regions having opposite conductivity types, and a first electrode for biasing its first region arranged in a trench extending from the surface of the second region opposite to the first region, the first electrode including, in top view, the following conductive elements: a polygonal ring; for each vertex of the polygonal ring, a first rectilinear bar extending between the vertex and the center of the ring, substantially along a direction running from the vertex to the center of the ring; and for each first bar, a plurality of second rectilinear bars extending from the first bar substantially parallel to the sides of the ring, starting from the vertex forming the origin of the first bar.
