Während Feinstdrähte aus Aluminium- und Aluminiumlegierungen bevorzugt für die Herstellung Ultraschall-geschweißter Verbindungen nach dem wedge-wedge-Verfahren eingesetzt werden, können die Kern/Mantel-Drähte (Kupfer-Aluminium-Feinstdrähte) sowohl durch Ultraschall-Schweißen nach dem wedge-wedge-Verfahren als auch durch Thermosonic-Schweißen nach dem Verfahren der Nagelkopf-Kontaktierung mit den Halbleiter-Bauelementen und den Anschlußelementen verbunden werden.While fine wires made of aluminum and aluminum alloys are preferred for the production of ultrasonic welded connections are used according to the wedge-wedge process, the core / sheath wires (copper-aluminum fine wires) both by ultrasonic welding according to the wedge-wedge method and by thermosonic welding according to the method the nail head contact with the semiconductor components and the connection elements are connected.

Die mechanische Festigkeit und (Ii 12 elektrische 1. ι; i i. fiili icjke j I. der Verbindung ■ zwischen diesen Kcrn/Hiinli1 1 -Drähten und HnJbleiter-Dauelementen ist·gut. Bei der Ausbildung der Verbindung zwischen dem Draht und aus Kupfer oder einer Kupferlegierung bestehendem Anschlußelement, zum Beispiel einem Systemträyer, . können jedoch Schaden auftreten, die - unter Retr i ubsbedi rifjungen - zu einem Ablösen des Drahtes führen.The mechanical strength and (Ii 12 electrical 1. ι; i i. Fiili icjke j I. of the connection between these Kcrn / Hiinli 1 1 wires and permanent conductor elements is good. In the formation of the connection between the wire and from Copper or a copper alloy connection element, for example a system carrier, can, however, occur damage which - under retrofitting requirements - lead to the wire becoming detached.

Die .Zuverlässigkeit von integrierten Halbleiter-Bauteilen hängt in hohem Maße von den Anschlußdrahten und drr Festigkeit ihrer Verbindung mit den Halbleiter-Bauelementen und den Anschlußelementen ab. So besteht ein Interesse an der Verbesserung der Anschlußdrähte und an der Ifntw i ek 1 uinj neuer, die auch durch die sparsamere Verwendung von I".dtvl m H a 1 I i'ii in drr Halbleiter-Technologie erforderlich wird.The .reliability of integrated semiconductor components depends to a large extent on the connection wires and the strength of their connection with the semiconductor components and the connection elements away. So there is an interest in improving the connecting wires and in the Ifntw i ek 1 uinj newer, the also through the more economical use of I ".dtvl m H a 1 I i'ii in drr Semiconductor technology becomes necessary.

Es ist daher die Aufgabe der Erfindung, einen Feinstdraht mit einem Durchmesser von 0,01 bis 0,06 mm zur Herstellung der Außenanschlusse von Halbleiter-Bauelementen zu finden, der sowohl mit aluminium-beschichteten Silicium-Halbleiter-Bauelementen als auch mit Anschlußelementen aus Kupfer oder Kupferlegierungen eine zuverlässige Verbindung bildet.It is therefore the object of the invention to provide a fine wire with a diameter of 0.01 to 0.06 mm for the production of Find external connections of semiconductor components, both with aluminum-coated silicon semiconductor components as well as with connection elements made of copper or copper alloys forms a reliable connection.

Die Aufgabe wird erfindungsgemäß durch die Verwendung eines Feinstdrahtes aus Kupfer oder einer. Kupferlegierung aus 98 bis 99,9 Gewichts-% Kupfer und 0,1 bis 2 Gowiclits;-?i Beryllium, Zinn, Zink, Silber, Zirkonium, Chrom oder Eisen gelöst.The object is achieved according to the invention through the use of a Fine wire made of copper or a. Copper alloy from 98 bis 99.9% by weight copper and 0.1 to 2 gowiclits; -? I beryllium, Tin, zinc, silver, zirconium, chromium or iron dissolved.

Besonders bewährt haben sich Feinstdrähte aus den Legierungen aus 99,4 Gewichts-% Kupfer und 0,6 Gewichts-% Zinn und aus 99,85 Gewichts-% Kupfer und 0,15 Gewichts-% Zirkonium.Very fine wires made from the alloys of 99.4% by weight of copper and 0.6% by weight of tin and made of have proven particularly useful 99.85% by weight copper and 0.15% by weight zirconium.

Zum Beispiel wrrdon Legierungen des Kupfers mit 1 Gewichts-% Zinn beziehungsweise mit 0,15 Gewichts-% Zirkonium in Dies, Kupfer und Kupfnrlogicrungen in der Technik, 1967, Seite 572, beziehungsweise in der deutschen Ausjegeschrift 10 90 437 beschrieben. Kup ΓϋΓ-Ι eni rrurujen cliuaer kind are known per se. For example wrrdon alloys of copper with 1% by weight of tin or with 0.15% by weight of zirconium in dies, copper and Kupfnrlogicrungen in der Technik, 1967, page 572, respectively described in the German Ausjegeschrift 10 90 437.

Die Verbindungsstellen (Bondstellen) Feinstdraht/ Kupfer und Feinstdraht/Kupferlegierung sind frei von Fehlstellen (Risse und dergleichen). Die Abreißfestigkeit der Paare Cu/Cu, CuSnO,6/Cu und CuZrO,15/Cu ist größer als die der Paare Cu/Al und Cu/Cu-Al.The fine copper and copper alloy wires are passed through U 1 I. raiifha 1 1 -iic: hu / uiC) (Mi after dom u / rulrjo-Vcjr proceed with dt; n Copper or Kup f (!!

The pull-off strength of the pairs Cu / Cu, CuSnO, 6 / Cu and CuZrO, 15 / Cu is greater than that of the pairs Cu / Al and Cu / Cu-Al.

Das Verbinden der Halbleiter-Bauelemente - zum Beispiel aus mit Aluminium beschichtetem Silicium - geschieht durch Thermosonic-Schweißen nach dem Verfahren der Nagelkopf-Kontaktierung, wobei das Abflammen des Feinstdrahtendes unter Bildung einer Kugel in einer Schutzgas-Atmosphäre erfolgt.The connection of the semiconductor components - for example made of silicon coated with aluminum - is done by thermosonic welding according to the method of nail head contacting, wherein the flaming of the fine wire end to form a Ball takes place in a protective gas atmosphere.
