Definitions
- the present invention relates to a semiconductor switching module according to the preamble of claim 1.
- Semiconductor switch modules are used when switching from load voltages of up to several hundred amperes frequently and almost silently at operating voltages of a few hundred volts.
- Wiring can be made with the load circuit to be switched.
- a large part of the interior of the module housing is filled with an insulating potting compound.
- For heat dissipation is also on the side of the base substrate, which is opposite to the side with the power semiconductor chip, a suitably sized heat sink attached.
- the power semiconductor element of such a semiconductor switching module can also be constructed according to the so-called planar technology.
- planar technology Such a planar structure of a power semiconductor element is known, for example, from WO 03/030247.
- the components are mounted on the base substrate, which consists of a ceramic base with copper layers applied on both sides. Further surface-applied layers of electrically isotropic In the case of insulating and electrically conductive materials, the components can then be contacted with one another in a planar manner and without additional wires or connected with connection elements.
- the use of such power semiconductor elements embodied in planar technology largely eliminates the wiring required in the bonding technology, but also in the conventional soldering technology.
- the isolation between the individual components and the electrically conductive layers is also effected here alone by the electrically insulating layers, so that it is possible to dispense with an additional potting compound.
- the electrically insulating layers thus serve, in particular when they extend almost over the entire surface of the power semiconductor element, to increase the creepage distances between the various conductive layers and components.
- semiconductor switching modules can be made more compact, less expensive and thus more cost-effective.
- Power semiconductor chips in semiconductor switching modules have a control connection for switching the load currents, to which a control signal is applied.
- a load current conducted via a load terminal and a base of the power semiconductor chip is then controlled and switched therewith.
- the connection of the load circuit and the control signal can be effected by means of the bonding or planar technology described above.
- the connection by means of the bonding technology has the disadvantage that it is very expensive.
- Connecting exclusively by means of planar technology has the disadvantage that the planar electrically conductive layers for connecting the load and control connections cover parts of the surface of the power semiconductor element and thus create complex and complex planar structures.
- Object of the present invention is to provide a semiconductor switching module in which the connection of the load terminals, but also the control terminals is less expensive overall.
- a running in planar technology power semiconductor element comprising a base layer, a copper layer, at least one mounted on the copper layer power semiconductor chip and another electrically conductive, and at least one load terminal of the power semiconductor chip overlapping and thus standing in electrical contact with this, layer .
- the means are formed so that they press with a contact surface surface on the electrically conductive layer.
- the semiconductor switching module according to the invention thus enables a simple connection of the load circuit to be switched to the load terminal of the power semiconductor chip.
- the inventively provided means allow a pressure contact for secure connection, which is less expensive than known bonding or solder joints.
- the further electrically conductive layer produced in planar technology which may consist in particular of copper, additionally serves as surface protection for the terminals of the power semiconductor chip. This is especially true for the load connection, which is claimed by the pressure contact accordingly.
- a very planar surface can be produced, which ensures a secure surface covering for the contact surface of the means.
- the sheet-like pressure contact in conjunction with a power semiconductor element produced in planar technology thus has the advantage of a significantly higher load cycle resistance compared to the point-like bonding types bonding and soldering. This is particularly important for applications with short-term high loads, as they are given for example in soft starters.
- the contact surface preferably has a surface shape which corresponds to a surface shape of the load connection.
- the pressure contact will be made directly on the power semiconductor chip.
- the power semiconductor element can be pressed exactly at the location of the power semiconductor chip on a, mounted on the opposite side of the power semiconductor element, the heat sink.
- optimal thermal contact between the ceramic of the power semiconductor element and the heat sink is achieved precisely at the location of the power semiconductor chip. This makes it possible to achieve a very good power dissipation from the power semiconductor chip to the heat sink.
- the further electrically conductive layer has to be extended beyond the surface of the power semiconductor chip in such a way that a planar contact can be produced next to the power semiconductor chip with the contact surface, between this electrically conductive layer and the surface of the underlying copper layer and the power semiconductor chip a electrically insulating layer is arranged, which has at the location where the load terminal of the power semiconductor chip, a window to establish an electrical contact between the further electrically conductive layer and the load terminal.
- the pressure contact can be used to achieve a spatial separation between the contact means for the load and control connection in addition to the power semiconductor chip.
- the means comprise at least one contact means and biasing means, wherein the biasing means press the at least one contact means with its contact surface areally on the further electrically conductive layer.
- the contact means must be designed as a hollow body for receiving a contact means for the control connection.
- the power semiconductor element and thus also the semiconductor switching module can be smaller overall, since no additional areas in addition to the power semiconductor chip for contacting are necessary.
- the contact means is formed, for example, in two parts, wherein the two parts together with a curvature surface together to lie down. The curvature allows the two parts to lie relative to each other so that a secure surface contact is achieved.
- the contact means may consist of annealed copper. Due to its lower hardness, it can then give way even with small misalignments and cling to the contact surface.
- the biasing means is designed as a bracket, which has a bulge in particular at the point where it comes into contact with the contact means. Due to the curved surface of the bulge of the biasing means a punctual force is exerted directly on the contact means. As a result, a secure contact is achieved, and also allows a compensation of misalignments.
- biasing means fastening means with which the bracket is attached for example, to a module housing, pressure is applied to the contact means only with the tightening of the fastening means of the biasing means.
- the fastening means may also be provided so that the bracket is connected directly to the power semiconductor element, which then can be dispensed with a module housing.
- Power semiconductor element, contact means and biasing means then form a unit that already assembled represents a reliable pressure contact and thus a functioning semiconductor switching module.
- the biasing means itself may also be part of the module housing of the semiconductor switching module. By eliminating the otherwise additional biasing means, the semiconductor switching module can be produced more cheaply.
- contact means and biasing means are integrally formed as a resilient element. That is, the contacting and the pressurization take place via a single component. This in turn achieves a more cost-effective semiconductor switching module.
- the contact agent can serve as a short-term heat store.
- the temperature of the power semiconductor chip can be kept within a permissible range.
- the contact means with only minimal thermal resistance is connected to the top of the power semiconductor chip and can thus very effectively short high Shut off power losses.
- the main cooling load is still taken over by the heat sink, which is provided on the side of the power semiconductor element, which lies opposite the side with the power semiconductor chip. The heat sink can then be dimensioned smaller.
- 1 shows a schematic representation of a first embodiment of the semiconductor switching module according to the invention
- 2 shows a schematic representation of a second embodiment
- FIG. 5 shows a schematic representation of a plan view of parts of the fourth embodiment.
- FIG. 1 schematically shows an inventive structure of a semiconductor switching module 1, as would be used, for example, in soft starters.
- the semiconductor switching module according to the invention comprises a power semiconductor element 10, as well as means 20 and 30 for securely connecting the load terminal L to a load current circuit, not shown.
- the semiconductor switching module also has a housing 40 and a heat sink 50, for dissipating the heat produced by a power semiconductor chip 140.
- the basis for the present invention is the power semiconductor element 10 constructed using Planar technology, as it is known, for example, from WO 03/030247.
- the power semiconductor element consists of a ceramic carrier 110 with two copper platings 120 and 130. On the copper layer 120 of the power semiconductor chip 140 is soldered.
- this electrically non-conductive layer 150 has a window, so that the load terminal L is exposed.
- another electrically conductive layer 160 is again applied by means of planar technology. Typical layer thicknesses of this electrically conductive layer 160, which preferably also consists of copper, amount to 100-200 ⁇ m.
- an insulating film may be applied by means of planar technology.
- means 20 and 30 for securely connecting the load terminal L to the load circuit to be switched by the power semiconductor chip 140 are now provided.
- the electrically conductive contact means 121 with its contact surface A is now pressed onto the electrically conductive layer 160, which is located directly above the load terminal L, via the means 30.
- this is done in particular by means of a bracket 130 which is screwed with a plurality of fastening means, here two screws 132, with the module housing 40 and which has a bulge 131.
- the semiconductor switching module When assembling the semiconductor switching module, it may, for example, due to dimensional tolerances of the individual components Menten, come to misalignment between the power semiconductor element 10, the means 20 and 30, the module housing 40 and the heat sink 50. As a result, contact surface A, which is generally large in area, will no longer be pressed onto the further electrically conductive layer 160 over the entire surface, which leads to an increased electrical contact resistance and thus to increased thermal losses of power semiconductor chip 140.
- a taper 128 is provided in the embodiment shown in FIG. 1 for the contact means 121.
- other measures such as the use of annealed copper as the material for the contact means 121 are possible.
- the bracket 130 is provided with a bulge 131 in order to ensure a punctual pressing and thus secure contact of the contact means 121 with the further, electrically conductive layer 150.
- FIG. 1 A second embodiment is shown in FIG.
- the contact means is formed in two parts: By appropriate shaping of the curvature surface W of the two parts elements 221 and 221 'sufficient mobility to compensate for any misalignment between contact means 221 and the power semiconductor element 10 is achieved.
- FIG. 3 shows various further contact means and biasing means according to the invention.
- the electrically conductive layer 160 is led beyond the power semiconductor chip 140.
- the contacting between contact means 321 and load connection L is also effected here via the further electrically conductive layer 160.
- FIG. 3 a further embodiment is shown in FIG.
- the here more rod-shaped contact means 322 in this case has a corresponding terminal 327 for connecting an electrical conductor 326.
- the contact means 322 can then be connected from the outside.
- the contact means 322 is guided in a groove 334. By this groove 334 the contact means is braced and at the same time small misalignments can be compensated.
- the contact means 323 is simultaneously biasing means. That is, by a suitable shaping and clamping in the module housing 40 presses the contact means 323 after assembly directly to another electrically conductive layer 160th
- FIG. 4 shows a further embodiment of a contact means 421 of the semiconductor switching module 1 according to the invention.
- the control connection S is generally surrounded by the load connection L.
- a large-area load connection L which is usually required for switching high currents can be achieved, while a small area is sufficient for the control connection S.
- the further electrically conductive layers 160 applied by the planar technology act as a protective layer for the load and the control connection.
- the mechanical loads on the connections can be reduced.
- the almost vertical contact makes it possible to achieve the greatest possible clearance and creepage distances. This has an advantageous effect in particular in connection with the application of an insulating film to increase the air and creepage distances.
