Abstract
Verfahren zum Anbringen von Kontakterhöhungen an Kontaktstellen einer elektronischen Mikroschaltung, bei dem an einem Ende eines Metalldrahtes mit Hilfe von Wärme eine Kugel gebildet wird, die Kugel gegen eine Kontaktstelle der elektronischen Mikroschaltung gedrückt und an dieser Kontaktstelle befestigt wird. Dabei wird in dem Draht in der Nähe der Kugel eine Schwachstelle angebracht und der Draht an dieser Schwachstelle getrennt.
Description
2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß die Kapillare über eine Strecke etwa
gleich dem 2- bis 3fachen der Drahtdicke aufwärts und über eine Strecke etwa gleich dem 1,5- bis 2fachen
der Di ahtdicke seitlich bewegt wird.

Die Erfindung bezieht sich auf ein Verfahren zum Anbringen von Kontakterhöhungen an Kontaktstellen
einer elektronischen Mikroschaltung.
Halbleiterbauelemente, die mit Kontakterhöhungen (auch als Kontaktkugeln oder »Bumps« bezeichnet) versehen
sind, sind bekannt. Auch andere elektronische Mikroschaltungen, wie magnetische BlasendomänenaJiordnungen
oder Flüssigkristallanordnungen, können mit Kontakterhöhungen versehen werden. Die Kontaktkugeln
dienen zur Herstellung eines elektrischen Kontakts mit Leitern auf einem Substrat oder mit Leitern
eines Metalleitergitters, wobei dann keine Verbindungsdrähte verwendet zu werden brauchen. Das bekannte
Verfahren zum Anbringen der Kontaktkugeln ist verhältnismäßig verwickelt und erfordert eine Anzahl
von Verfahrensschritten. Meistens werden die Kugeln in einer oder mehreren Metallschichten mit Hilfe
galvanischer Techniken angebracht, wobei zum Erhalten
einer richtigen Maskierung Photoätztechniken angewandt werden.
Aus der DE-OS 20 17 499 ist ein weiteres Verfahren zum Anbringen von Kontakterhöhungen an Kontaktstellen
einer elektronischen Mikroschaltung bekannt. Hierbei wird aus einem Vorratsbehälter mit kugelförmi-
-jggen Goldpartikeln ein Goldpartikel mit einem Saug- so
!^Werkzeug entnommen, dann zur ^Kontaktstelle transportiert
und dort mit Hilfe eines Preßwerkzeuges mit ■der Kontaktstelle verbunden. Die Goldpartikel müssen
'dabei separat hergestellt werden und müssen eine genaue Kugelform haben um ein Aufnehmen mit dem
Saugwerkzeug zu ermöglichen. Weiter ist dabei eine Einrichtung notwendig zur Erzeung von Unterdruck.
Der Erfindung liegt die Aufgabe zugrunde, ein sehr vereinfachtes Verfahren zum Anbringen von Kontaktkugeln
zu schaffen, bei dem das galvanische Anwachsen vermieden werden kann und auch keine gesonderten
kugelförmigen Partikel verwendet werden brauchen, und das auf hoch mechanisierter Weise ausführbar ist.
Diese Aufgabe wird von einem Verfahren mit den Merkmalen des Anspruchs 1 gelöst.
Die Kontaktkugeln werden dabei völlig auf mechanischem Wege während des Verfahrens aus einem Metalldraht
erhalten. Zusätzliche Photoätz- und Galvanisierungstechniken sind überflüssig. Separates Herstellen
von kugelförmigen Partikeln erübrigt sich. Die Anbringung der Kontaktkugoln kann auf stark mechanisierte
Weise stattfinden. Dabei können teilweise in der Halbleiterherstellung bekannte Techniken zum Anbringen
von Drahtverbindungen, wie sie z. B. aus der DE-OS 26 21 138 bekannt sind, verwendet werden. Durch das
vereinfachte Verfahren zum Anbringen der Kontaktkugeln kann eine erhebliche Kosteneinsparung erreicht
werden. Die Weise von Anbringung der Schwachstelle ist besonders wichtig um eine geeignete Form der Kontaktkuge!
zu erhalten. Die Unterseite der Kapillare kann den Draht auf eine bestimmbare Weise schwächen,
wobei eine große Reproduzierbarkeit der Kontaktkugeln erhalten wird. Jetzt verfügbare Steuermittel,
bei denen z. B. Mikroprozessoren benutzt v/erden können, ermöglichen es, die Lage der Schwachstelle sehr
genau vorherzubestimmen.
Bei einer Ausführungsform der Erfindung wird die Kapillare über einen Abstand etwa gleich dem 2- bis
3fachen der Drahtdicke aufwärts und über einen Abstand gleich etwa dem 1,5- bis 2fachen der Diahtdicke
seitlich bewegt.
Einige Ausführungsformen der Erfindung sind in der Zeichnung dargestellt und werden im folgenden näher
beschrieben. Es zeigt
Fig. 1 das Unterende einer Kapillare mit einem Draht, an dem sich eine Kugel gebildet hat;
F i g. 2 die auf ein Substrai gedruckte und daran befestigte
Kugel;
Fig.3 die Lage, in der die Kapillare aufwärts und
seitlich bewegt ist;
F i g. 4 das Plätten und Schwächen des Drahtendes;
F i g. 5 das mit einer Kontakterhöhung versehene Substrat, nachdem der Draht getrennt worden ist, und
F i g. 6 eine auf andere Weise auf einem Substrat angebrachte Kontakterhöhung.
In Fig. 1 ist ein Substrat 1 mit einer Kontaktstelle 2
dargestellt, an der eine Kontakterhöhung oder Kontaktkugel angebracht werden muu. In der nachstehenden
Beschreibung wird angenommen, daß das Substrat ein Halbleiterbauelement ist und daß die Kontaktstelle eine
metallisierte Zone ist, die mit einem aktiven Gebiet im Halbleiterbauelement in Verbindung steht. Die Erfindung
kann jedoch auch bei anderen elektronischen Mikroschaltungen, wie bei magnetischen Blasendomänen
oder bei Flüssigkristallen oder bei bei Hybridschaltungen in der Mikroelektronik verwendeten Trägern, angewandt
werden. Ein mit Kontakterhöhungen versehenes Substrat kann an Leitern eines Trägers befestigt werden,
wobei die Verbindung sämtlicher Kontakterhöhungen mit den Leitern gleichzeitig hergestellt wird und
keine Verbindungsdrähte erforderlich sind.
In Fig. 1 ist über dem Halbleiterbauelement 1 das Unterende- einer Kapillare 3 dargestellt. Durch eine
Bohrung 4 der Kapillare ist ein Draht 5 geführt. Am Ende des Drahtes 5 hat sich eine Kugel 6 gebildet. Dies
kann auf an sich bekannte Weise, z. B. mit Hilfe einer
Gasflamme oder mit Hilfe einer elektrostatischen Entladung, erfolgen. Das Material des Drahtes ist meistens
Gold oder Aluminium; auch andere Metalle, wie z. B. Kupfer, sind verwendbar. Die Kapillare 3 kann z. B. aus
einem keramischen Material bestehen. Erforderlichenfalls kann die Kapillare durch an sich bekannte Mittel
erhitzt werden.
Fig.2 zeigt den mit der Kontaktstelle 2 auf dem
Halbleiterbauelement 1 verbundenen Draht. Die Kugel 6 ist dabei mit Hilfe der Kapillare 3 gegen die Kontaktstelle
2 gedruckt und daran mit Hilfe von Thermokompression oder Ultraschallschwingungen befestigt worden.
Dann wird die Kapillare 3 über eine kleine Strecke seitlich verschoben. Diese Lage ist in F i g. 3 dargestellt.
Anschließend wird die Kapillare nach unten gedrückt (F i g. 4), wobei eine Schwachstelle in Form einer Einkerbung
7 in dem Draht gebildet wird. Dank dieser Schwachstelle kann der Draht leicht getrennt werden.
In F i g. 5 ist das Substrat 1 mit einer darauf angebrachten Kontakterhöhung als Kontaktkugel 8 dargestellt
Erwünschtenfalls können an weiteren Kontaktstellen des Substrats 1 Kontakterhöhungen angebracht werden.
Das auf mechanische Wege mit Kontakterhöhungen versehene Substrat kann nun auf an sich bekannte
Weise mit Leitern eines Trägers verbunden werden.
Es hat sich als besonders vorteilhaft erwiesen, wenn
die Kapillare nach Befestigung der Kugel auf dem Substrat eine Aufwärtsbewegung gleich etwa dem 2- bis
3fachen der Drahtdicke und eine seitliche Bewegung gleich dem 1,5- bis 2fachen der Drahtdicke vollführt Die
Schwachstelle im Draht wird dann auf günstige Weise und an einer gewünschten Stelle erhalten.
