Description
- Selektive Material-Entfernung mit Hilfe kathodischer Zerstäubung Die Erfindung befaßt sich mit einem verfahren zur selektiven Entfernung von Material aus einem Werkstück durch kathodische Zerstäubung. Die Methode gemäß Erfindung ist besonders nützlich bei der selektiven Entfernung von Material aus einem Werkstück, das nicht den hohen Spannungs-Unterschieden unterworfen werden kann, die gewöhnlich an das kathodisehe Teil im Zerstäubungsverfahren angelegt werden. Es ist in Verbindung mit dem kathodischen Zerstäubungsv.erfahren bekannt, daB die Oberflächen von Werkstoffen gereinigt oder, in der Wirkung dasselbe, mittels des Zeratäubungs-Verfahrens geätzt werden können, insofern als das kathodische Teil selbst durch die Bombardierung erodiert wird, was für die Zerstäubung ein grundlegendes Merkmal ist. Na ist offenbar, daß eine Art Reinigung als folge der Entfernung von Oberflächenschichten eintritt. Indessen veranlaßt die Anwendung der kathodischen Zeretäubungs-Technik zwecks Entfernung von Schichten von der Oberfläche von Halbleiter-Körpern unter Verwendung von Potentialen in der Größenordnung von 3 bis 10 Kilovolt an das kathodische Teil Dauerschäden am Halbleiter-Körper. Dieser Schaden ist besonders bedeutungsvoll im Fall o=yd-geschidtzter Halbleiter-Körper ineof ern, als starke elektrische Felder den dauernden Zusammenbruch der dielektrischen Schicht bewirken. Gegenstand der Erfindung ist dementsprechend eine Anordnung zur selektiven Material-Entfernung von der Oberfläche eines Werkstoffs, ohne direkt hohe Spannungen an das Werkstück anzulegen. Im speziellen ist ein ärfindungegegenstand,die Rückzeretäubunge-Teohnik, um die selektive Entfernung Ton Teilen einen Oberflächen-Überzugs auf einer Halbleiter- fläche, welche dielektrisehe Orydfilme hat, zu bewirken. Gemäß Erfindung wird das WerkstüQk Ton der Kathode durch eine Isolieraoh@oht getrennt und die Kathode so abgeschirmt, daß sich die Bildung eines Glimmentladunga-Bereieha um die Peripherie des Halbleiter-Werkstücke ergibt. 8ennzeichnenderweise kann der Glimmentladunga-Bereich die form einen runden Ringe oder einer rechteckigen Schleife annehmen. Dieser Glimmentladunge-Bereich neigt zur ,Ausbreitung von der Kathodenfläche hinweg und füllt iemzufolge den zentralen Raum direkt über dem Werkstück teilweise aus. Das Ergebnis der Bildung einer kathodiechen Glimmentladung in dieser Form seranlaßt die Gaa-Ionen, die innerhalb der Vakuumkammer der Zerstäubungs-Apparatur gebildet werden, sich in den Glimmentladungs-Bereich zu begeben, dort Energie zu gewinnen und sich durch Kollision in den Raum oberhalb des Werkstücks zu bewegen und dort durch weitere Kollision mit anderen Ionen im wesentlichen senkrecht auf die Oberfläche des Werkstücke zu treffen. Es ist dieser Ionenstoß, der offenbar die Zerstäubungswirkung und die Materialentfernung vom getroffenen Stück hervorruft. So wird die Oberfläche den Halbleiter-Werkatücke bombardiert, ohne daß das Halbleiter-Stück direkt vom Nochspannungaf eld durchsetzt wird, welches in der Kathode zur 1rzeugung des Glimmentladunge-Bereiche dient. Insoweit als der Ionenstoß im wesentlichen senkrecht auf die Werkstoff-7liehe erfolgt, strebt die Nate.. rialentfernung zu einem sehr präzisen Verlauf mit einer praktisch eoharfkantigen Bchneidwirkung längs der Grenzen einer in verschiedener Weise bedeckten Oberfläche, In diesem Zusammenhang ist die Erfindung
