Die Priorität der Anmeldung in Grosebritannien vom 21.MaI I965 Hr. 216OO/65 1st in Anspruch genommen.The priority of registration in Great Britain from May 21, 1965 Mr. 216OO / 65 is used.
Die vorliegende Erfindung betrifft zunächst ein Halbleiterbauelement, dessen Halbleiterelement auf einem metallischen Körper, insbesondere einem metallischen Gehäuseteil, elektrisch isoliert aufgebaut ist.The present invention initially relates to a semiconductor component, whose semiconductor element is electrically insulated on a metallic body, in particular a metallic housing part is constructed.
Durch die vorliegende Erfindung soll ferner ein Herstellungsverfahren für derartige Halbleiterbauelemente angegeben werden, das eine elektrisch isolierende, aber thermisch gut leitende Verbindung mit einem metallischen Gehäuseteil ohne zusätzliche Einfügung eines besonders für diesen Zweck ausgelegten Teiles zwischen dem Halbleiterelement und dem Gehäuseteil ermöglicht.The present invention is also intended to provide a manufacturing method for such semiconductor components are specified, which is an electrically insulating, but thermally highly conductive Connection to a metallic housing part without the additional insertion of a part specially designed for this purpose allows between the semiconductor element and the housing part.
Das Halbleiterbauelement, dessen Halbleiterelement auf einem metallischen Körper elektrisch isoliert aufgebaut ist, zeichnet sich erfindungsgemäss dadurch aus, dass das Halbleiterelement innerhalb einer Epltaxschlcht auf der einen Oberfläche einer Halbleiterplatte angeordnet ist und dass der metallische Körper an einer Isolierschicht auf der anderen Oberfläche der Halbleiterplatte befestigt ist.The semiconductor component, the semiconductor element of which is electrically insulated on a metallic body, draws according to the invention in that the semiconductor element is arranged within an Epltaxschlcht on the one surface of a semiconductor plate and that the metallic body is attached to an insulating layer on the other surface of the semiconductor board.

unmittelbar mit einem einen Bestandteil eines Gehäuses bildenden metallischen Körper zu verbinden* Dies ermöglicht eine wirksame Abführung der im Halbleiterbauelement erzeugten Wärme· Für be· stimmte Anwendungen, insbesondere für Hoohfrequenzbetrleb, 1st es jedoch oft vorzuziehen oder fUr das Halbleiterelement wesentlich, dass es vom Gehäuse elektrisch isoliert ist, In solchen Fällen war es Üblich, eine Scheibe aus einem Material wie Berylliumoxyd zwischen dem metallischen Körper und dem Halbleiterelement anzuordnen. Das Halbleiterelement wird in gutem thermischem Kontakt mit der Scheibe verbunden, die wiederum auf ähnliche Weise am Gehäuse befestigt ist. Berylliumoxyd wie andere geeignete Materialien zum Herstellen der Scheiben weisen eine hohe thermische Leitfähigkeit auf, sind jedoch elektrisch isolierend· Derartige Aufbaumittel machen aber, abgesehen von den zusätzlich erforderlichen Arbeitegängen, die am einzelnen Halbleiterelement durchgeführt werden müssen, auch die Verwendung von teuren Einzeltellen (Berylliumoxydsoheiben) erforderlich, die bei anderen Typen von Halbleiterbauelementen nicht Üblich sind.directly with a forming part of a housing metallic body to connect * This allows effective Dissipation of the heat generated in the semiconductor component For be In certain applications, especially for high frequency operations, it is often preferable or essential for the semiconductor element to be electrically isolated from the housing, in such cases In some cases, it has been customary to place a disk made of a material such as beryllium oxide between the metallic body and the semiconductor element. The semiconductor element is connected in good thermal contact with the disk, which in turn is attached to the housing in a similar manner. Beryllium oxide like others Suitable materials for manufacturing the panes have a high thermal conductivity, but are electrically insulating. However, apart from the additionally required work steps that have to be carried out on the individual semiconductor element, including the use of expensive individual parts (beryllium oxide discs) required, which are not common in other types of semiconductor components.
Es ist vorzuziehen, dass die Arbeitsgänge in die Herstellung des Halbleiterelementes einbezogen werden, so dass das Halbleiterelement nach dem Aufbau innerlich isoliert ist. Ein derartiges Verfahren wird nun an einem Beispiel der Herstellung eines Silicium-Planar-Hoohfrequenz-Leistungetransistors nach der Erfindung anhand der Zeichnung erläutert, in derIt is preferable that the operations involved in making the Semiconductor element are included, so that the semiconductor element is internally insulated after construction. Such a method will now be explained using an example of the production of a silicon planar high frequency power transistor according to the invention with reference to the drawing, in which

Als Ausführungsform der vorliegenden Erfindung wird ein n-p-n-Silioiunj-Planartransistor nach folgenden Verfahren hergestellt. Die'Arbeltegänge veranschaulicht die Figur la-e. Eine Platte aus η-leitendem Silicium 1, etwa 0,02 cm dick und 2,5 om im Durchmesser mit einem spezifischen Widerstand von vorzugsweise 0,001 Dem - höchstens aber 0,1 Ωοιη - wird im Reaktionsraum einer Vorrichtung zum epitaktischen Aufwachsen angeordnet und eine Epitaxschicht 2 aus n-leltendem Silicium mit einem spezifischen Widerstand von vorzugsweise 2 Dem - mindestens aber 0,4 Dem und einer Dicke von 15 Mikron einkristallin auf einer ihrer Oberflächen aufgewachsen. Die andere Oberfläche 3 der Platte wird danach bis auf eine QesamtplattenatHrke von etwa 0,0075 om abgeläppt. Auf beide Oberflächen der Platte wird dann eine1 Schicht von Siliciumoxyd 4, 5 von etwa 1,5 Mikron, Dicke durch Erhitzen auf HOO0C über 6 Stunden in einer Atmosphäre von mit Wasserdampf gesättigtem Sauerstoff aufgewachsen. Die Platte wird anschliessend in den Reaktionsraum der Vorrichtung für die Epitaxie zurückgebracht« Auf der Oxydsohicht 5 der vorher geläppten Plattenoberfläohe wird eine weitere Siliciumschioht 6, •twa 0,0125 om dick mit einem sehr hohen spezifischen Widerstand, vorzugsweise von mehr als 100 Dem, aufgewachsen. Diese Schicht wird polykristallin sein und kann mit einer weit grösseren Geschwindigkeit als bei epitaktischem Wachstum aufgewachsen werden. Die Aufrauhung dieser Oberfläche 3 während des Läppprozesses wird die Haftung auf dieser Schicht begünstigen.As an embodiment of the present invention, an npn silicon planar transistor is manufactured by the following method. Die'Arbeltegänge illustrates the figure la-e. A plate of η-conductive silicon 1, about 0.02 cm thick and 2.5 μm in diameter with a specific resistance of preferably 0.001 Dem - but at most 0.1 Ωοιη - is placed in the reaction space of a device for epitaxial growth and an epitaxial layer 2 of n-type silicon with a specific resistance of preferably 2 Dem - but at least 0.4 Dem and a thickness of 15 microns grown monocrystalline on one of its surfaces. The other surface 3 of the plate is then lapped to a total plate thickness of about 0.0075 μm. On both surfaces of the plate a 1 layer of silicon oxide 4, 5 of about 1.5 microns, thickness is grown by heating to HOO 0 C for 6 hours in an atmosphere of oxygen saturated with water vapor. The plate is then returned to the reaction chamber of the device for epitaxy. On the oxide layer 5 of the previously lapped plate surface, another silicon layer 6, about 0.0125 μm thick with a very high specific resistance, preferably more than 100 Dem, is grown . This layer will be polycrystalline and can be grown at a much faster rate than with epitaxial growth. The roughening of this surface 3 during the lapping process will promote adhesion to this layer.
