A 3-D structure formed in a recess of a substrate delimited by walls, including a large number of rectangle parallelepipedic blades extending from the bottom of the recess to the substrate surface while being oriented perpendicularly to one another and formed in a pattern covering the whole surface of the recess, some blades being non-secant to one of the walls, each non-secant blade being connected to one of the walls by at least another perpendicular blade.

High-density 3-dimensional structure

A self-cooled electronic component comprising a vertical monolithic circuit, in which the vertical monolithic circuit is electrically connected in series with a Peltier cooler so that the D.C. current flowing through the circuit supplies the cooler and in which the circuit and the cooler are placed against each other so that the cold surface of the cooler is in thermal contact with the circuit.

Self-cooled vertical electronic component

A semiconductor component in which the active junctions extend perpendicularly to the surface of a semiconductor chip substantially across the entire thickness thereof. The contacts with the regions to be connected are provided by conductive fingers substantially crossing the entire region with which a contact is desired to be established.

Active semiconductor component with a reduced surface area

A vertical rectifying and protection power diode, formed in a lightly-doped semiconductor layer of a first conductivity type, resting on a heavily-doped substrate of the first conductivity type, having a first ring-shaped region, of the first conductivity type more heavily-doped than the layer and more lightly doped than the substrate, surrounding an area of the layer and extending to the substrate; and a second ring-shaped region, doped of the second conductivity type, extending at the surface of the first region and on either side thereof; a first electrode having a thin layer of a material capable of forming a Schottky diode with the layer, resting on the area of the layer and on at least a portion of the second ring-shaped region with which it forms an ohmic contact.

Rectifying and protection diode

A semiconductor component in which the active junctions extend along at least one cylinder perpendicular to the main surfaces of a semiconductor chip substantially across the entire thickness thereof, said cylinder(s) having a cross-section with an undulated closed curve shape.
