Die Erfindung betrifft ein halbleitendes Elektrodensystem, z. B. einen Transistor oder eine Kristalldiode, mit einer Metallhülle, die mittels einer Kaltschweißung verschlossen ist. Eine solche Metallhülle ist z. B. in der französischen Patentschrift 1130175 beschrieben.The invention relates to a semiconducting electrode system, e.g. B. a transistor or a crystal diode, with a metal shell that is closed by means of a cold weld. Such a metal shell is z. Am the French patent 1130175 described.
Dabei kann eine Kaltschweißung Verwendung finden, um z. B. zwei Teile des Gehäuses, insbesondere einen Boden und einen Deckel, zu verbinden oder um ein metallenes Pumpröhrchen zu verschließen.A cold weld can be used to make z. B. two parts of the housing, in particular a base and a lid, to connect or to close a metal pump tube.
Eine so verschlossene Metallhülle, insbesondere zur Verwendung bei Entladungsröhren, ist bereits in der britischen Patentschrift 561111 beschrieben, in der auch ausgeführt ist, daß einer der Vorteile der angewendeten Kaltschweißung darin zu sehen ist, daß keine Gasentwicklung auftritt.A metal shell closed in this way, in particular for use in discharge tubes, is already in British Patent 561111, which also states that one of the advantages of applied cold welding can be seen in the fact that no gas development occurs.
Überraschenderweise hat sich jedoch gezeigt, daß die elektrischen Eigenschaften von in kaltgeschweißten Metallhüllen angeordneten halbleitenden Elektrodensystemen sich nach der Kaltschweißung verschlechtern. Bei Dioden nahm insbesondere der Leckstrom zu.Surprisingly, however, it has been shown that the electrical properties of in cold-welded Metal sheaths arranged semiconducting electrode systems deteriorate after the cold welding. In the case of diodes, the leakage current increased in particular.
Der Erfindung liegt nun die Erkenntnis zugrunde, daß diese Erscheinungen auf das Auftreten von Gasen oder festen Verunreinigungen beim Kaltschweißen zurückzuführen sind, und die Erfindung zielt u. a. auf die Beseitigung dieses Nachteiles ab.The invention is based on the knowledge that these phenomena are due to the occurrence of gases or solid contaminants in cold welding, and the invention aims i.a. aimed at eliminating this disadvantage.
Gemäß der Erfindung ist in der Hülle zwischen dem halbleitenden Elektrodensystem und der genannten Kaltschweißung eine mechanische Abschirmung derart angebracht, daß der direkte Weg zwischen der Kaltschweißstelle und dem Elektrodensystem unterbrochen ist.According to the invention, there is in the sheath between the semiconducting electrode system and the aforementioned Cold welding a mechanical shield attached in such a way that the direct path between the cold weld and the electrode system is interrupted.
Es hat sich nämlich gezeigt, daß von der Kaltschweißstelle »explosionsartig«, d. h. ganz kurzzeitig, Gase und eventuell andere Teilchen ausgehen und es daher ausreichend ist, wenn der direkte Weg zwischen der Kaltschweißstelle und dem Elektrodensystem unterbrochen ist.It has been shown that from the cold weld point "explosively", i. H. very briefly, Gases and possibly other particles go out and it is therefore sufficient if the direct route between the cold weld and the electrode system is interrupted.
Es sei noch erwähnt, daß aus der französischen Patentschrift 1149 240 ein in einer kaltgeschweißten Metallhülle angeordnetes halbleitendes Elektrodensystem bekannt war, bei dem der Innenraum der Hülle durch ein Montageblech in zwei Teile aufgeteilt ist. Das halbleitende Elektrodensystem erstreckt sich jedoch zu beiden Seiten des Montagebleches, so daß dies den direkten Weg zwischen der oder den Kaltschweißstellen und dem Elektrodensystem nicht unterbricht.It should also be mentioned that from French patent specification 1149 240 a cold-welded in a Metal shell arranged semiconducting electrode system was known, in which the interior of the Shell is divided into two parts by a mounting plate. The semiconducting electrode system extends However, on both sides of the mounting plate, so that this is the direct path between the or the Cold welds and the electrode system.
Gemäß weiteren Ausgestaltungen der Erfindung besteht die Abschirmung aus einer elektrisch isolierenden Scheibe, die an einer Zuleitung des Systems befestigt ist oder aus einem rings um das System an-According to further refinements of the invention, the shield consists of an electrically insulating one Disc, which is attached to a supply line of the system or from a one around the system.

geordneten Röhrchen, das an einem Teil der Hülle befestigt ist.ordered tube attached to part of the envelope.
Falls das Gehäuse mittels mehr als einer Kaltschweißung abgedichtet ist, reicht eine Abschirmung zwischen der letzten Kaltschweißstelle und dem Elektrodensystem aus, sofern es möglich ist, beim Ausführen der anderen Kaltschweißung(en) die erzeugten Gase oder schädlichen Verunreinigungen abzusaugen. If the housing is sealed by means of more than one cold weld, a shield is sufficient between the last cold weld and the electrode system, if possible, during execution the other cold weld (s) to extract the generated gases or harmful impurities.
Es sei bemerkt, daß im allgemeinen unter Kaltschweißung eine Verschweißung zu verstehen ist, die dadurch entsteht, daß zwei Metalle von etwa gleicher Härte aufeinander angeordnet werden und anschließend senkrecht zur Berührungsebene ein so hoher Druck ausgeübt wird, daß ein starkes Fließen des Metalls in einer Richtung senkrecht zu der des Preßdrucks erfolgt. Durch dieses Fließen des Metalls wird die etwaige Oxydhaut des Metalls zerrissen, und die beiden Teile fließen zusammen. Im vorliegenden Fall sind unter der Bezeichnung »Kaltschweißung« aber auch Verschweißungen zu verstehen, bei denen das Metall von nur einem der beiden Teile zum Fließen gebracht wird, weil gerade bei der starken Verformung von Metallen Gase oder schädliche Verunreinigungen frei werden und das Zusammenfließen zweier Teile an sich dabei keine Rolle spielt.It should be noted that, in general, cold weld is to be understood as a weld which arises from the fact that two metals of approximately the same hardness are placed on top of one another and then so high a pressure is exerted perpendicular to the contact plane that a strong flow of the Metal takes place in a direction perpendicular to that of the pressing pressure. Through this flow of the metal any oxide skin on the metal is torn, and the two parts flow together. In the present In this case, however, the term "cold welding" also includes welds, in which the metal is made to flow by only one of the two parts, because straight when metals are deformed, gases or harmful impurities are released and that The confluence of two parts in itself does not matter.
