Description
Die Erfindung betrifft ein Leistungshalbleitermodul, das ein Substrat mit einer schaltstrukturierten Metalllage aufweist, an der mindestens ein eine Gatefläche und eine im Vergleich hierzu große Emitterfläche aufweisendes Leistungshalbleiterchip angeordnet ist, das mittels einer flexiblen Schaltfolie verschaltet ist, und mit mindestens einem Temperatursensor.The The invention relates to a power semiconductor module comprising a substrate having a schaltstrukturierten metal layer, on the at least a gate area and a comparatively large emitter surface exhibiting Power semiconductor chip is arranged, which by means of a flexible Switching foil is interconnected, and with at least one temperature sensor.
Bei bekannten Leistungshalbleitermodulen werden die Temperatursensoren oftmals neben den Leistungshalbleiterchips auf dem Substrat angeordnet. Bei dem Substrat kann es sich beispielsweise um ein DCB (Direct Copper Bonding) oder um ein IMS (Integrated Metal Substrate) Substrat handeln.at known power semiconductor modules are the temperature sensors often arranged next to the power semiconductor chips on the substrate. For example, the substrate may be a DCB (Direct Copper Bonding) or an IMS (Integrated Metal Substrate) substrate act.
Temperatursensoren, die bei bekannten Leistungshalbleitermodulen seitlich neben den Leistungshalbleiterchips angeordnet sind, messen jedoch nicht die Temperatur der Leistungshalbleiterchips sondern eine durch einen Kühlkörper des Leistungshalbleitermoduls beeinflusste niedrigere Temperatur. Der resultierende thermische Widerstand ist stark von dem verwendeten Kühlkörper abhängig.Temperature sensors, in known power semiconductor modules laterally next to the Power semiconductor chips are arranged, but do not measure the Temperature of the power semiconductor chips but one by one Heatsink of the Power semiconductor module influenced lower temperature. Of the resulting thermal resistance is greatly different from that used Heatsink dependent.
Desgleichen wurde bereits vorgeschlagen, Temperatursensoren in die Leistungshalbleiterchips zu integrieren. Dabei ergibt sich jedoch das Problem, dass die in die Leistungshalbleiterchips integrierten Temperatursensoren keine Potentialtrennung besitzen und aktive Chip-Fläche der Leistungshalbleiterchips verbrauchen. Bei Leistungshalbleitermodulen mit einer Vielzahl Leistungshalbleiterchips ergibt sich außerdem das Problem, dass die in die Leistungshalbleiterchips integrierten Temperatursensoren nur mit großem schaltungstechnischem Aufwand ausgewertet werden können.Similarly has already been proposed, temperature sensors in the power semiconductor chips too integrate. However, the problem arises that in the Power semiconductor chips integrated temperature sensors no potential separation own and active chip area consume the power semiconductor chips. For power semiconductor modules with a variety of power semiconductor chips also gives the Problem that the temperature sensors integrated into the power semiconductor chips only with big circuit complexity can be evaluated.
In Kenntnis dieser Gegebenheiten liegt der Erfindung die Aufgabe zugrunde, ein Leistungshalbleitermodul der eingangs genannten Art mit einer einfachen und optimal wirksamen Temperatursensorik auszubilden.In Knowledge of these circumstances, the invention is based on the object a power semiconductor module of the type mentioned with a form simple and optimally effective temperature sensors.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1, d. h. dadurch gelöst, dass der mindestens eine Temperatursensor auf der vom Substrat abgewandten Oberseite der flexiblen Schaltfolie über der relativ großen Emitterfläche des mindestens einen Leistungshalbleiterchips angebracht ist.These The object is achieved by the Features of claim 1, d. H. solved by the fact that the at least one Temperature sensor on the side facing away from the substrate top of flexible switching foil over the relatively large one Emitter surface of the at least one power semiconductor chip is mounted.
Das erfindungsgemäße Leistungshalbleitermodul weist die Vorteile auf, dass für den mindestens einen Temperatursensor keine aktive Chipfläche des mindestens einen Leistungshalbleiterchips benötigt wird, und dass eine genaue Temperaturmessung des Leistungshalbleiterchips gewährleistet wird, weil die thermische Anbindung des Temperatursensors an das Leistungshalbleiterchip bei dem erfindungsgemäßen Leistungshalbleitermodul im Vergleich zur thermischen Anbindung eines Temperatursensors, der auf dem Substrat neben dem Leistungshalbleiterchip vorgesehen ist, wesentlich besser ist.The Power semiconductor module according to the invention has the advantages that for the at least one temperature sensor no active chip area of at least a power semiconductor chip is needed, and that an accurate Temperature measurement of the power semiconductor chip guaranteed is because the thermal connection of the temperature sensor to the Power semiconductor chip in the power semiconductor module according to the invention in comparison to the thermal connection of a temperature sensor, the is provided on the substrate next to the power semiconductor chip, is much better.
Die zu erwartende kapazitive Kopplung des Temperatursensors zur Emitterfläche des Leistungshalbleiterchips kann z. B. in einfacher Weise durch entsprechende Filter geglättet werden.The expected capacitive coupling of the temperature sensor to the emitter surface of the Power semiconductor chips can z. B. in a simple manner by appropriate Smoothed filter become.
Bei dem erfindungsgemäßen Leistungshalbleitermodul kann die flexible Schaltfolie eine schaltstrukturierte Metallfolie oder ein Folienverbund sein, der aus einer ersten und einer zweiten Metallfolie, die schaltstrukturiert sind, und einer isolierenden Folie besteht, die zwischen der ersten und der zweiten Metallfolie vorgesehen ist. Eine derartige Ausbildung der flexiblen Schaltfolie der zuletzt genannten Art weist außerdem den Vorteil auf, dass der Temperatursensor wegen der Isolationslage, d. h. der isolierenden Folie zwischen der ersten und der zweiten Metallfolie, isoliert ausgewertet werden kann.at the power semiconductor module according to the invention the flexible switching foil can be a structured metal foil or a film composite consisting of a first and a second Metal foil, which are schematized, and an insulating foil which is provided between the first and the second metal foil is. Such a design of the flexible switching foil of the last mentioned type also indicates the advantage that the temperature sensor, because of the insulation layer, d. H. the insulating film between the first and the second metal foil, can be evaluated in isolation.
