Description
Die Erfindung bezieht sich auf ein Verfahren zum Konkaktieren eines Siliziumhalbleiterkörpers eines Halbleiterbauelementes mit Hilfe von Ultraschall.The invention relates to a method for making contact with a Silicon semiconductor body of a semiconductor component with the aid of ultrasound.
Die Anwendung von Ultraschall ist in der Halbleitertechnik ein bekannter Verfahrensschritt. So werden z. B. polykristalline Selenschichten unter Ultraschalleinwirkung erzeugt. Es ist auch bekannt, eine Legierungsbildung bei der Herstellung von legierten Kontakten durch Anwendung von Ultraschall zu unterstützen.The use of ultrasound is well known in semiconductor technology Process step. So z. B. polycrystalline selenium layers under the action of ultrasound generated. It is also known to form alloys in the production of alloys Support contacts by applying ultrasound.
Die Anbringung von Elektroden durch Legieren ist in vielen Fällen sehr nachteilig. Beispielsweise werden bei einem steuerbaren Halbleitergleichrichter bisher der Anoden- und der Steuerkontakt in einem Arbeitsgang einlegiert. Einerseits hängt die Größe des notwendigen Steuerstromes von der geometrischen Lage des Steuerkontaktes ab, die aber andererseits erst nach dem Einlegieren des Anodenkontaktes bestimmt werden kann. In solchen Fällen ist es wünschenswert, den Elektrodenkontakt nachträglich ohne Anwendung des Legierungsverfahrens anzubringen.The attachment of electrodes by alloying is common in many cases very disadvantageous. For example, in a controllable semiconductor rectifier previously the anode and control contacts were alloyed in one operation. On the one hand the size of the necessary control current depends on the geometric position of the control contact which, on the other hand, is only determined after the anode contact has been alloyed can be. In such cases it is desirable to make the electrode contact later without using the alloying process.
Diese Aufgabe wird gemäß der Erfindung bei einem Siliziumhalbleiterkörper dadurch gelöst, daß ein Elektrodenkörper aus Aluminium oder mit einem Aluminiumüberzug, so mit der Aluminiumfläche auf dem Silizium-Halbleiterkörper unter Ultraschalleinwirkung gerieben wird, daß zwischen dem Elektrodenkörper und dem Halbleiterkörper eine mechanisch feste Verbindung entsteht.According to the invention, this object is achieved with a silicon semiconductor body solved in that an electrode body made of aluminum or with an aluminum coating, so with the aluminum surface on the silicon semiconductor body under the action of ultrasound is rubbed that between the electrode body and the semiconductor body a mechanical solid connection is created.
Zweckmäßig wird als Elektrodenkörper eine 0,2 bis 1 mm dicke Wolframscheibe mit einem auf einer Scheibenfläche auflegierten, 50 #t dicken überzug aus Aluminium verwendet. A 0.2 to 1 mm thick tungsten disk with a 50 t thick aluminum coating alloyed on a disk surface is expediently used as the electrode body.
Vorteilhaft kann als Elektrodenkörper auch eine 0,3 mm dicke Aluminiumscheibe verwendet werden. Als Elektrodenkörper können Kreisscheiben von etwa 1 oder mehr Millimeter Durchmesser günstig verwendet werden. Zweckmäßig wird als Zuleitung ein Nickeldraht verwendet. A 0.3 mm thick aluminum disk can also advantageously be used as the electrode body. Circular disks with a diameter of about 1 or more millimeters can be used favorably as the electrode body. A nickel wire is expediently used as the supply line.
Besonders vorteilhaft ist die Verwendung einer Scheibe oder eines Streifens aus Wolfram, Molybdän, Eisen, Nickel, einer Eisen-M' ckel-Legierung oder einer Eisen-Nickel-Kobalt-Legierung mit einem Aluminiumüberzug auf einer Scheibenfläche als Kontaktmaterial.The use of a disk or one is particularly advantageous Strips made of tungsten, molybdenum, iron, nickel, an iron-M 'ckel alloy or an iron-nickel-cobalt alloy with an aluminum coating on a disc surface as contact material.
Nach einer vorteilhaften Weiterbildung des Verfahrens nach der Erfindung wird zum Anbringen eines Elektrodenkörpers an einer Siliziumscheibe einer Halbleiteranordnung durch Aufreiben eines Elektrodenmaterials unter Ultraschall so verfahren, daß ein Elektrodenkörper aus einem aluminisierten Draht aus Nickel, Kupfer, Eisen oder einer Eisen-Nickel-Legierung verwendet wird und der aluminisierte Draht mit seiner Mantelfläche an seinem einen Ende auf die Siliziumscheibe unter Ultraschalleinwirkung aufgerieben wird. Eine vorteilhafte Ausführungsform dieses Verfahrens besteht auch darin, daß ein Elektrodenkörper aus einem Kopfdraht aus Nickel, Kupfer, Eisen oder einer Nickel-Eisen-Legierung mit einem Aluminiumkopf verwendet wird und daß der Kopf des Kopfdrahtes auf die Siliziumscheibe unter Ultraschalleinwirkung aufgerieben wird. Von besonderem Vorteil ist die Verwendung des Verfahrens nach der Erfindung zum Anbringen der Steuerelektrode an der Siliziumscheibe eines steuerbaren Halbleitergleichrichters.According to an advantageous development of the method according to the invention is used to attach an electrode body to a silicon wafer of a semiconductor device proceed by rubbing an electrode material under ultrasound so that a Electrode body made of an aluminized wire made of nickel, copper, iron or a Iron-nickel alloy is used and the aluminized wire with its jacket surface rubbed at one end onto the silicon wafer under the action of ultrasound will. An advantageous embodiment of this method is that an electrode body made of a head wire made of nickel, copper, iron or a nickel-iron alloy with an aluminum head used and that the head of the head wire on the Silicon wafer is rubbed under the action of ultrasound. Of particular advantage is the use of the method according to the invention for attaching the control electrode on the silicon wafer of a controllable semiconductor rectifier.
Nach dem Verfahren gemäß der Erfindung können Elektroden mit Kontaktflächen von etwa 0,5 bis 10 mm2 an Siliziumscheiben angebracht werden, die Kontakte mit guten mechanischen und elektrischen Eigenschaften aufweisen.According to the method according to the invention, electrodes with contact areas of approximately 0.5 to 10 mm 2 can be attached to silicon wafers which have contacts with good mechanical and electrical properties.
