- • Bei der Herstellung wird die automatisierte Bestückung des Substrates mit Bauelementen erschwert.
- • Eine für den Wärmeabtransport während der Verwendung des Leistungshalbleiterbauelemente notwendige plane stoffschlüssige Auflage auf einer Grundplatte ist erschwert.
- • Bei grundplattenlosen Leistungshalbleitermodulen wird während der Verwendung der Wärmeübergang zu einem stoffbündig darunter angeordneten Kühlkörper verschlechtert.
- • During production, the automated assembly of the substrate with components is made more difficult.
- • A flat cohesive support on a base plate, which is necessary for the heat removal during the use of the power semiconductor components, is made more difficult.
- • In the case of base-less power semiconductor modules, the heat transfer to a heat sink arranged flush beneath it is degraded during use.
Ausgangspunkt
der Erfindung ist weiterhin die
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde ein Leistungshalbleitermodul vorzustellen, welches eine reduzierte Durchbiegung des Substrates aufweist und somit einen besseren thermischen Kontakt des Substrates zu einer Grundplatte oder einem Kühlkörper gewährleistet.Of the The present invention is based on the object of a power semiconductor module to imagine what a reduced deflection of the substrate has and therefore a better thermal contact of the substrate guaranteed to a base plate or a heat sink.
Diese Aufgabe wird gelöst durch ein Leistungshalbleitermodul nach dem Anspruch 1, spezielle Ausgestaltungen finden sich in den Unteransprüchen.These Task is solved by a power semiconductor module according to claim 1, special Embodiments can be found in the subclaims.
Der Grundgedanke der Erfindung geht aus von einem Leistungshalbleitermodul mit Grundplatte oder zur direkten Montage auf einem Kühlkörper. Dieses besteht aus einem Gehäuse, mindestens einem Leistungshalbleiterbauelement sowie mindestens einem beidseitig mit einer metallischen Schicht versehenen elektrisch isolierenden Substrat. Das mindestens eine Leistungshalbleiterbauelement ist auf der ersten in sich strukturierten und somit einzelne Leiterbahnen bildenden metallischen Schicht angeordnet und mit dieser schaltungsgerecht beispielhaft mittels Drahtbondverbindungen verbunden. Diese erste metallische Schicht befindet sich auf der ersten, dem Inneren des Leistungshalbleitermoduls zugewandten Hauptfläche des Substrates, während die zweite metallische Schicht auf der zweiten Hauptfläche des Substrates angeordnet ist.Of the The basic idea of the invention is based on a power semiconductor module with base plate or for direct mounting on a heat sink. This consists of a housing, at least one power semiconductor device and at least one on both sides provided with a metallic layer electrically insulating substrate. The at least one power semiconductor component is on the first in itself structured and thus individual tracks forming metallic layer and arranged with this circuit connected by way of example by wire bonds. This first Metallic layer is located on the first, the inside of the Power semiconductor module facing the main surface of the substrate, while the second metallic layer disposed on the second major surface of the substrate is.
Das erfindungsgemäße Leistungshalbleitermodul weist auf der zweiten metallischen Schicht eine Vielzahl von Vertiefungen auf. Dies Vertiefungen sind regelmäßig oder unregelmäßig über die gesamte Fläche der metallischen Schicht angeordnet. Weiterhin weisen diese Vertiefungen eine Tiefenausdehnung auf, die geringer ist als die Dicke der zweiten metallischen Schicht.The Power semiconductor module according to the invention has a plurality of depressions on the second metallic layer on. These recesses are regular or irregular over the the whole area the metallic layer arranged. Furthermore, these depressions a depth extent that is less than the thickness of the second metallic Layer.
Vorteilhaft an dieser Ausgestaltung der zweiten metallischen Schicht des erfindungsgemäßen Leistungshalbleitermoduls ist, dass durch die teilweise Unterbrechung der Oberfläche diese und damit die gesamte Schicht gezielt geschwächt wird. Diese Schwächung kompensiert die durch die Strukturierung der ersten Oberfläche dort entstandene Schwächung. Somit wird eine oben beschriebene Durchbiegung des Substrates deutlich reduziert.Advantageous in this embodiment of the two th metallic layer of the power semiconductor module according to the invention is that by the partial interruption of the surface of these and thus the entire layer is weakened targeted. This weakening compensates for the weakening caused by the structuring of the first surface. Thus, a deflection of the substrate described above is significantly reduced.
Weiterhin vorteilhaft an der erfinderischen Ausgestaltung eines Leistungshalbleitermoduls ist, dass die Vertiefungen Inhomogenitäten oder Überschüsse des Auftrags von Wärmeleitpasten zwischen dem Substrat und eine Kühlkörper durch die Aufnahme dieser ausgleichen.Farther advantageous to the inventive embodiment of a power semiconductor module is that the pits inhomogeneities or excesses of the order of thermal compounds between the substrate and a heat sink through the inclusion of this balance.
