Description
Die Erfindung bezieht sich auf ein gewölbtes Metall-Keramik-Substrat gemäß Oberbegriff Patentanspruch 1.The invention relates to a curved metal-ceramic substrate according to the preamble of
Bekannt ist die Herstellung von Metall-Keramik-Substraten, die jeweils aus einer Keramikschicht mit einer Metallisierung an beiden Oberflächenseiten der Keramikschicht bestehen, und zwar mit Hilfe des sogenannten ”DCB-Verfahrens” (Direct-Copper-Bond-Technology) und unter Verwendung von Metallisierung bildenden Metall- bzw. Kupferfolien oder Metall- bzw. Kupferblechen, die an ihren Oberflächenseiten eine Schicht oder einen Überzug (Aufschmelzschicht) aus einer chemischen Verbindung aus dem Metall und einem reaktiven Gas, bevorzugt Sauerstoff aufweisen. Bei diesem beispielsweise in der
Bekannt ist auch ein Metall-Keramik-Substrat (
Das Substrat wird im Verwendungsfall mit seiner konvex gewölbten Unterseite gegen einen Kühlkörper angelegt und angedrückt, so dass es dann flach und angepresst gegen den Kühlkörper anliegt. Hierdurch soll ein verbesserter Wärmeübergang zwischen Substrat und dem Kühlkörper erreicht werden. Nachteilig ist aber, dass die Anpresswirkung des Substrates allein durch die unterschiedlich dicken Metallschichten bewirkt wird, während die durch die unterschiedlichen mechanischen Spannungen in den Metallschichten, d. h. durch Einwirkung äußerer Kräfte verformte Keramikschicht dieser Anpresswirkung entgegenwirkt. Außerdem gehen insbesondere bei Verwendung von Kupfer als Metall die Anpresswirkung und damit die angestrebte Verbesserung des Wärmeübergangs durch Alterung und Fließen des Metalls verloren, ebenso auch bei größerer Erwärmung der konkaven Oberseite des Substrats durch Verlustwärme der auf dem Substrat vorgesehenen Bauelemente.The substrate is applied in the case of use with its convexly curved bottom against a heat sink and pressed so that it then flat and pressed against the heat sink. As a result, an improved heat transfer between the substrate and the heat sink to be achieved. The disadvantage, however, is that the pressing action of the substrate is effected solely by the metal layers of different thicknesses, while those caused by the different mechanical stresses in the metal layers, d. H. counteracted by the action of external forces deformed ceramic layer of this contact pressure. In addition, especially when using copper as the metal, the contact pressure and thus the desired improvement in heat transfer through aging and flow of the metal are lost, as well as greater heating of the concave top of the substrate by heat loss of the components provided on the substrate.

Aufgabe der Erfindung ist es, ein Metall-Keramik-Substrat aufzuzeigen, welches bei einer vereinfachten Herstellung, beispielsweise mit Hilfe der DCB-Technik, eine optimale Kühlwirkung gewährleistet.The object of the invention is to show a metal-ceramic substrate, which ensures an optimal cooling effect in a simplified production, for example by means of the DCB technique.
Zur Lösung dieser Aufgabe ist ein Metall-Keramik-Substrat entsprechend dem Patentanspruch 1 ausgebildet.To solve this problem, a metal-ceramic substrate is formed according to
Die Krümmung des erfindungsgemäßen Substrats besteht ohne äußere Kräfte oder Krafteinwirkung. Hierfür besitzen die beiden, jeweils unter Verwendung der DCB-Technik auf die Oberflächenseiten der Keramikschicht aufgebrachten Metallisierungen die selbe Dicke, so dass sowohl bei der Herstellung des Substrates, als auch bei der späteren Verwendung dieses Substrates ein Bimetall-Effekt bei Temperaturänderungen weitgehend vermieden werden kann. Durch die Krümmung des Substrates ist es möglich, dieses im Verwendungsfall elastisch derart in eine ebene Form zu biegen, dass es aufgrund der elastischen Spannung der Keramikschicht dicht und fest gegen eine Fläche einer wärmeableitenden Metallfläche anliegt und sich hierdurch eine verbesserte Wärmeableitung ergibt, insbesondere auch bei Verwendung einer Kühlpaste zwischen dem Substrat und der Metallplatte. Das Anliegen des Metall-Keramik-Substrates gegen die Metallfläche wird somit in erster Linie durch die elastischen Eigenschaften der Keramikschicht erreicht.The curvature of the substrate according to the invention is without external forces or force. For this purpose, the two have each applied to the surface sides of the ceramic layer using the DCB technique Metallizations the same thickness, so that a bimetallic effect with temperature changes can be largely avoided both in the preparation of the substrate, as well as in the subsequent use of this substrate. Due to the curvature of the substrate, it is possible, in the case of use, to elastically bend this into a planar shape so that it rests tightly and firmly against a surface of a heat-dissipating metal surface due to the elastic stress of the ceramic layer, resulting in improved heat dissipation, in particular also Use of a cooling paste between the substrate and the metal plate. The concern of the metal-ceramic substrate against the metal surface is thus achieved primarily by the elastic properties of the ceramic layer.
Bei dem Krümmungsgrad, welchen die Erfindung vorsieht, ist auch ein Brechen der Keramikschicht mit Sicherheit vermieden. Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche. Die Erfindung wird im Folgenden anhand der Figuren an einem Ausführungsbeispiel näher erläutert. Es zeigen:At the degree of curvature which the invention provides, breaking of the ceramic layer is certainly avoided. Further developments of the invention are the subject of the dependent claims. The invention will be explained in more detail below with reference to the figures of an embodiment. Show it:
