- the diode consists of an active region of type N or of type?, Placed on a region of the same type, that is to say or?, But much more heavily doped.
- the metal making the Schottky contact constitutes the anode, while the other face of the substrate which is metallized and which constitutes an ohmic contact, is called the cathode.
- the sustained voltage withstand in reverse depends on the doping of the N-type or P-type zone, and the lower this is, the higher the voltage withstand.
- the limit of the withstand voltage is around 100 volts.
- the voltage drop in the on state is in fact the sum of the voltage drop in the semiconductor layer charge associated with the Schottky barrier, and the ohmic voltage drop in the semiconductor.
- the voltage drop values commonly encountered for Schottky diodes operating in the on state are of the order of 0.5 volts.
- Schottky diodes of the "JBS rectifier" type In order to improve the operating characteristics both in the blocked state and in the on state of the Schottky diodes, it has been necessary to design Schottky diodes of the "JBS rectifier" type. These second generation diodes are globally structurally identical to the preceding Schottky diodes, but are nevertheless distinguished by the fact that they comprise semiconductor mserts of a type contrary to the type of the semiconductor layer associated with the Schottky barrier.
- This arrangement makes it possible to limit the reduction mechanism of the Schottky barrier under high applied voltage and to limit the reverse current of the diode.
- the capacity withstand voltage of these devices can reach approximately 200 volts and the voltage drop, in the on state, is of the order of 0.25 volts.

- the first main surface 4 is covered on the one hand with a peripheral film 7 based in particular on oxide and is arranged so as to be in ohmic contact with the first layer 2 at the level of a central electrode 8.
- This central electrode 8 forms the anode of the device and is produced by means of a material forming a Schottky-type contact with the semiconductor.
- This material is chosen from in particular molybdenum, tungsten platinum, palladium or equivalent, it may also be a metallic alloy (silicide, etc.).
- This electrode 8 is arranged so as to be adjacent to the peripheral film 7 and forms a Schottky barrier with the first layer 2, at the level of the substantially central zone of the semiconductor substrate 1.
- the second main surface 5 also cooperates with a second electrode 6 which is arranged so as to be in ohmic contact with the second layer 3.
- This electrode 6 made of a metal constitutes the cathode of the semiconductor device which is the subject of the invention.
- the second layer 3 of the first type or of the second type exhibits a greater doping, in terms of quantity of impurities introduced into the layer, compared to the first layer of the first or second type.
- the impurities introduced into the first type layer will in particular be arsenic, phosphorus, while the impurities introduced into the second type layer will in particular be boron.
- the semiconductor device which is the subject of the invention (see FIGS. 2 and 8), it comprises a semiconductor substrate 1 identical in its constitution to the semiconductor device 1 as described in the first preferred embodiment, and differs from it in that it comprises, in the first layer 2 of first type (N) or of second type (P), a plurality of semiconductor regions 10 of opposite type of conduction to those surrounding it, the plurality of regions 10 extending from the first main surface 4 and from the electrode 8 to the interior of the first layer 2.

- MBE Beam Epitaxy Molecule
- these islands 9 can take various profiles (square, rectangle, triangle, circle, hexagon, octagon, or more generally polygon ”) or be arranged in the form of bands of homogeneous patterns or plumes, possibly overlapping each other according to the layers or being positioned randomly, thus being able, depending on the shape of the patterns, to have overlapping zones in the thickness of the superimposed layers.
- the islands 9 can be aligned or non-aligned, equid stants or non-equidistant, homogeneous or non-homogeneous, from the point of view of their characteristic directions (thickness, length and width).
- the islands 9, of the first type or of the second type may have a uniform doping or a non-uniform doping: there may thus be a doping gradient or this doping may be distributed according to a Gaussian law or another distribution.

- the inclusion of a plurality of 9-doped islands within a layer 2 of the first type or second type semiconductor substrate 1 makes it possible to create, in reverse operating mode (blocked state), a reduction in the global electric field by a distribution mechanism thereof at each of the islands.
- the islands 9 are in the form of spaced networks (cf. FIG. 5).

- These islands 9 are constituted in particular by semiconductor strips of the first type or of the second type; the choice of the type of islands 9 being however of the opposite type with respect to the type of the semiconductor layer in which they are included.
- the inclusion of the islands 9 in the semiconductor substrate is therefore not continuous and therefore has mter-island spaces through which the current can flow between the anode and the cathode.
- FIG. 6 shows the evolution of the value of the series resistance created in the layer within which the islands are incorporated, as a function of the reverse voltage withstand of the dipole; in this example, the dipole is a Schottky diode. From this FIG.
- the operating mechanisms previously studied for a dipole, in particular of the Schottky diode type comprising a plurality of floating islands, are identical when these islands are included in a dipole structure of type, for example JBS diode, and the operating values, both in blocked mode and in passing mode, for such a dipole (cf. FIG. 8;, are identical to those found for equivalent devices of the prior art, but for a value of reverse voltage withstand which is of the order of 600 volts (100 to 200 volts approximately for the devices of the prior art), and which can go up to 1000 volts.
- the main applications envisaged using this new semiconductor component substrate structure are in particular in the field of current rectification.
- This component can find in particular developments in the field of lighting (electronic ballast).
- This electronic component can also be used at the level of engine control, automotive electronics (rectifier component for alternator, or component integrated in integrated power circuits.
