Description

Die Erfindung bezieht sich auf ein halbleitendes Elektrodensystem, welches aus einem halbleitenden Körper, einer oder mehreren Elektroden sowie mit diesen Elektroden bereits vor einem nachfolgenden Ätzprozeß verbundenen Stromzuleitungen besteht.
Es ist bekannt, solche Elektrodensysteme, deren halbleitender Körper z. B. aus Germanium oder Silizium bestehen kann, nach dem Anbringen der Elektroden und der Stromzuleitungen einer Ätzbehandlung zu unterwerfen. Da die üblichen Ätzmittel nicht nur die Oberfläche des halbleitenden Körpers, sondern auch die der Zuleitungen chemisch angreifen, besteht die Gefahr, daß die dadurch in Lösung gehenden Elemente die halbleitende Oberfläche beschmutzen, was einen beträchtlichen Rückgang der elektrischen Eigenschäften eines solchen Systems zur Folge hat.
Der Erfindung liegt die Entdeckung zugrunde, daß, obzwar Chrom und Nickel von den üblichen Ätzmitteln angegriffen werden, manche Legierungen dieser Metalle bestehen, die nicht angegriffen werden.
Nach der Erfindung besteht wenigstens eine Stromzuleitung aus einer Legierung von Chrom und Nickel, die wenigstens einen so großen Gehalt eines jeden dieser Elemente aufweist, daß ein chemischer Angriff bei den üblichen Ätzmitteln nicht auftritt. Die Legierung enthält vorzugsweise wenigstens 5 % eines dieser Metalle. Eine besonders gut brauchbare Legierung enthält 20% Chrom und 80% Nickel.
Die Erfindung wird an Hand eines durch eine Zeichnung verdeutlichten Ausführungsbeispiels näher erläutert.
Die Zeichnung ist eine schematische Darstellung eines Schnitts einer Kristalldiode.
Die Diode besteht aus einem Germanium-Einkristall 1 der η-Art mit einer Stärke von 0,5 mm und einer Oberfläche von 3 · 3 mm. Der spezifische Widerstand beträgt z.B. 15 Ohm/cm. Der Kristall ist mittels einer 10% Antimon enthaltenden Zinnmenge 2 auf einem vergoldeten Molybdänplättchen 3 festgelötet, welches etwa den gleichen Ausdehnungskoeffizienten wie Germanium besitzt. Auf der Oberseite des Kristalls ist eine aus Indium bestehende sogenannte Legierungselektrode 4 aufgeschmolzen. Eine aus einer Legierung von 20% Chrom und 80% Nickel bestehende Zuleitung 5 ist in der Elektrode 4 befestigt.
Im allgemeinen braucht man selbstverständlich Stromzuleitungen nur aus einer solchen Legierung Halbleitendes Elektrodensystem
