Bei der industriellen Produktion von Chips für die Halbleiterindustrie werden integrierte Schaltungen auf Träger-Halbleiterscheiben, nachfolgend Wafer genannt, durch verschiedene Verfahren hergestellt. Dabei werden die Wafer während der Bearbeitung und der Lagerung in sogenannten Waferhaltern aufbewahrt.at industrial production of chips for the semiconductor industry integrated circuits on carrier semiconductor wafers, hereinafter referred to as wafers, produced by various methods. In the process, the wafers are during the processing and storage stored in so-called wafer holders.

Aus dem Stand der Technik sind weiterhin Waferhalter bekannt, die für chemische Ätzverfahren und für Waferbearbeitungen wie Belackungen konzipiert sind. Der Wafer wird dabei durch ein Vakuum gehalten und gegen ein Prozessmedium abgedichtet. Dabei kann ein Druckausgleich hinter dem Wafer durch Be- und Entlüftung erfolgen. In sogenannten Nassätzlinien können individuell Waferhalterungen so angeordnet werden, dass die Siliziumscheiben oh ne mechanische Beanspruchung im Ätzmedium gehalten werden. Nachteilig sind aus dem Stand der Technik bekannte Waferhaltungen vergleichsweise aufwendig konzipiert.Out Wafer holder are known in the prior art, which are used for chemical etching and for wafer processing how lacquers are designed. The wafer is thereby by a Held vacuum and sealed against a process medium. It can a pressure compensation behind the wafer by ventilation. In so-called wet etching lines can individually wafer holders are arranged so that the silicon wafers oh ne held mechanical stress in the etching medium become. Disadvantages are known from the prior art wafer attitudes designed comparatively expensive.
Aufgabe der vorliegenden Erfindung ist es, einen Waferhalter bereitzustellen, der einfach ausgestaltet ist und die Behandlung der Wafer durch Chemikalien oder durch Reinigung beidseitig gestattet, wobei die Fläche des Wafers, auf der sich Strukturen befinden, nicht verunreinigt oder beschädigt werden. Die Aufgabe wird gelöst durch einen Waferhalter gemäß Hauptanspruch. Vorteilhafte Ausgestaltungen ergeben sich aus den rückbezogenen Ansprüchen.task the present invention is to provide a wafer holder, which is simply designed and the treatment of the wafer through Chemicals or by cleaning allowed on both sides, the area of the wafer on which structures are located, not contaminated or damaged become. The task is solved by a wafer holder according to the main claim. Advantageous embodiments result from the back related Claims.
Der Waferhalter weist Mittel zum Halten eines Wafers in einer vorgegebenen Position auf. Das Mittel ist derartig ausgestaltet, daß es den Wafer nur an dessen Außenkante in seiner Position hält.Of the Wafer holder has means for holding a wafer in a predetermined Position up. The means is designed such that it Wafer only on its outer edge holding in his position.
Das Mittel des Waferhalters berührt den Wafer nur an dessen unempfindlicher Außenkante. Die Ober- und Unterseite des Wafers werden nicht berührt. Vorhandene empfindlichen Strukturen auf der Waferober- bzw. -unterseite werden nicht beschädigt, können andererseits aber bearbeitet werden.The Touched means of the wafer holder the wafer only at its insensitive outer edge. The top and bottom of the wafer are not touched. Existing delicate structures on the wafer top and bottom can not be damaged, on the other hand but to be worked on.
Vorteilhaft weist das Mittel eine sich stetig verengende Geometrie auf, in der der Wafer gehalten wird.Advantageous the agent has a steadily narrowing geometry in which the wafer is held.
Das Mittel ist in Form eines Langloches ausgestaltet.The Means is designed in the form of an oblong hole.
Im Langloch wird der Wafer in senkrechter Position gehalten. Das Langloch verengt sich in Aufsicht gesehen an seinen Enden derartig, dass ein Wafer nur an seinen Außenkanten gehalten wird. Ein solcher Waferhalter ist somit insbesondere zum Halten eckiger Wafer, bzw. Waferteilstücke geeignet. Selbstverständlich kann aber auch ein runder Wafer in einem als Langloch ausgestalteten Mittel gehalten werden.in the Long hole, the wafer is held in a vertical position. The slot narrows seen in supervision at its ends so much that a wafer only on its outer edges is held. Such a wafer holder is thus in particular for Holding square Wafer, or Waferteilstücke suitable. Of course you can but also a round wafer in a long hole Funds are kept.
Das als Langloch ausgestaltete Mittel weist erfindungsgemäß in der Aufsicht an seinen Enden zwei sich gegenüberliegende Rundungen in Form zweier halbkreisförmiger Bögen auf, an denen zwei Außenkanten eines Wa fers anliegen. Die halbkreisförmigen Bögen bilden jeweils eine sich verengende Geometrie in Bezug auf einen Punkt außerhalb des jeweiligen Bogens. Der weiteste Abstand eines halbkreisförmigen Bogens zum Bezugspunkt wird durch den Scheitelpunkt eines Bogens festgelegt. Das Langloch ist vorteilhaft so ausgestaltet, dass in den sich gegenüberliegenden halbkreisförmigen Bögen der Wafer gehalten wird, ohne dass dieser verkantet.The designed as a slot means according to the invention in the View at its ends two opposite curves in the form of two semicircular Bows on, where two outer edges a Wa fers abut. The semicircular arches form one each narrowing geometry with respect to a point outside the respective arc. The farthest distance of a semicircular arc to the reference point is determined by the vertex of an arc. The slot is advantageously designed so that in the opposite semicircular Bows of the Wafer is held without this tilted.
Durch eine derartige ausgestaltete Rundung bzw. Rundungen wird ein Wafer an dessen Außenkante oder Außenkanten punktuell in seiner Position gehalten. Die Bruchgefahr der Wafer während des Haltens ist minimiert.By such a configured rounding or rounding becomes a wafer at the outer edge or outer edges selectively held in position. The risk of breakage of the wafers while holding is minimized.
Die Mittel zum Halten des Wafers werden erfindungsgemäß zusätzlich von mindestens einem Stift begrenzt. Der Stift ist als Rundstift mit kreisförmiger Grundfläche ausgebildet. Auch der Rundstift hält den Wafer wegen seiner abgerundeten Oberfläche nur punktuell und positioniert den Wafer zusätzlich im Waferhalter.The means for holding the wafer are according to the invention additionally limited by at least one pin. The pin is circular as a round pin ger base area formed. Also, the round pin holds the wafer only selectively because of its rounded surface and additionally positions the wafer in the wafer holder.
Im Weiteren wird die Erfindung an Hand eines Ausführungsbeispiels und der beigefügten Figuren näher beschrieben.in the Further, the invention with reference to an embodiment and the accompanying figures described in more detail.
Alle Angaben in den Figuren sind in Millimeter bemessen.All Information in the figures are measured in millimeters.

Der erfindungsgemäße Waferhalter kann zur Behandlung der Wafer durch Chemikalien oder Reinigung bei unterschiedlichen Temperaturen eingesetzt werden, wobei die Flächen des Wafers, auf der sich Strukturen befinden, nicht verunreinigt oder beschädigt werden. Die Wafer werden beim Schwenken in den verschiedenen Flüssigkeiten gut umspült, und der Verbrauch von teuren Chemikalien minimiert. Weiterhin kann die Halbleiterfläche während der Behandlung mit Chemikalien gut beobachtet werden, da sich die Wafer gut beobachten lassen und damit der Entwicklungsfortschritt eindeutig dokumentiert werden kann.The wafer holder according to the invention can be used for treating the wafers by chemicals or cleaning at different temperatures, wherein the surfaces of the wafer, on which structures are located, are not contaminated or damaged. The wafers are well-lapped when swirling in the various liquids and the consumption of expensive chemicals is minimized. Furthermore, the semiconductor surface can be well observed during the treatment with chemicals, since the wafers can be well observed and thus the Development progress can be clearly documented.
