Abstract
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Vereinzeln und Sortieren scheibenförmiger Substrate gemäß dem Oberbegriff des Anspruchs 1. Scheibenförmige Substrate, die vereinzelt werden sollen, können als Stapel, auf einer Unterlage haftend vorliegen, wie es oft in der Waferherstellung der Fall ist. Sie können aber auch als Stapel ohne Unterlage vorliegen. Zwischen den scheibenförmigen Substraten des Stapels herrschen adhäsive Kräfte. Dabei kann es zum Haften der einzelnen scheibenförmigen Substrate aneinander kommen. Fertigungsbedingt können sich Fluide und Feststoffpartikel in den Zwischenräumen der scheibenförmigen Substrate befinden.The The present invention relates to a device for separating and Sort disc-shaped Substrates according to the preamble of claim 1. Disc-shaped Substrates to be singulated can be stacked on one Underlay liable to exist, as is often the case in wafer production Case is. You can but also available as a stack without pad. Between the disc-shaped substrates of the stack, adhesive forces prevail. there it may be to adhere the individual disc-shaped substrates together come. Manufacturing-related can Fluids and solid particles in the interstices of the discoid Substrates are located.
Die Vereinzelung solcher scheibenförmiger Substrate, wie z. B. in der Waferherstellung, wird z. Z. manuell durchgeführt. Haftet der Stapel scheibenförmiger Substrate, in dem die scheibenförmigen Substrate oft vertikal ausgerichtet sind, noch an einer Unterlage, so werden meist Teilstapel manuell abgelöst und danach vereinzelt. Dabei wird das oberste scheibenförmige Substrat des Stapels mit den Fingerspitzen an den Rändern erfasst und parallel zum nächsten weggezogen. Die Vereinzelung in orthogonaler Richtung zur Substratfläche ist auf Grund der Haftkräfte schwer möglich. Verformungen und Brüche würden die Folge sein. Die manuelle Vereinzelung birgt jedoch Gefahren. Unerwünschte Beschädigungen der scheibenförmigen Substrate können provoziert werden, besonders dann, wenn die Spannweite der menschlichen Hand ein Erfassen des Randes der scheibenförmigen Substrate nicht mehr erlaubt. Aber auch dann, wenn die Substrate sehr dünn sind, kann manuelle Vereinzelung zu Beschädigungen führen. Wichtig ist die gleitende parallele Verschiebung, die zum großen Teil auf dem Fluidfilm erfolgt und möglichst wenig Reibungsanteile der Flächen der scheibenförmigen Substrate aneinander aufweisen soll. Daher darf die Reibung nicht so groß sein, dass sie diesem Vereinzelungsprinzip entgegensteht. Das zu vereinzelnde scheibenförmige Substrat muss so gut gleiten, dass keine Beschädigungen, wie Verformungen und Brüche entstehen können.The Separation of such disc-shaped substrates, such as B. in wafer production, z. Z. manually performed. adheres the stack is disk-shaped Substrates in which the disc-shaped Substrates are often aligned vertically, still on a base, usually partial stacks are detached manually and then separated. there becomes the top disc-shaped Substrate of the stack with the fingertips captured at the edges and parallel to the next pulled away. The separation in the orthogonal direction to the substrate surface is due to the adhesive forces hardly possible. Deformations and fractures would be the To be a follower. Manual separation, however, carries risks. Unwanted damage the disc-shaped Substrates can be provoked, especially when the span of the human Hand no longer detecting the edge of the disc-shaped substrates allowed. But even if the substrates are very thin, Manual separation can lead to damage. Important is the sliding parallel displacement, in large part on the fluid film done and as possible little friction of the surfaces the disc-shaped Substrates should have to each other. Therefore, the friction must not be that big that it conflicts with this separation principle. The one to be singled discoid Substrate must slide so well that no damage, such as deformation and breaks can arise.

In WO 01/28745 A1 kleben die Substrate an der Unterlage und zeigen während des Vereinzelns vertikal nach oben. Gelenkt durch einen Positionssensor wird das äußerste scheibenförmige Substrat über seinen wesentlichen Flächenbereich mit einen Greifer erfasst. An dem Greifer sitzen einzelne, mit Vakuum beaufschlagte Greiferarme. Sie saugen an definierten Stellen an dem Substrat, was danach entgegengesetzt zur Klebenaht nach oben gezogen und oszillierend von seiner Klebestelle gerüttelt wird. Gleichzeitig wird – zur Unterstützung der Abtrennung – das äußerste Substrat mit einem Flüssigkeitsstrahl hinterspült. Das Substrat wird zur Weiterbehandlung entfernt. Das sensorische Feedback für die wirkliche Vereinzelung nur eines Substrates fehlt, egal ob in guter oder schlechter Qualität. Höchstwahrscheinlich wird auftretender Bruch am nächsten zu lösenden Substrat kleben und mit diesem gemeinsam fortgeführt. Damit ist das verklebte (gute) Substrat Ausschuss, da es im nachfolgenden Reinigungsschritt nicht von den Bruchstücken gesäubert werden kann. Das Verfahren ist somit ungeeignet für die Vereinzelung.In WO 01/28745 A1 glue the substrates to the substrate and show while singulating vertically upwards. Steered by a position sensor becomes the outermost disc-shaped substrate over its significant surface area detected with a gripper. On the gripper sit individual, with vacuum loaded gripper arms. They suck in defined places the substrate, which then opposite to the adhesive seam upwards pulled and oscillated by its splice is shaken. simultaneously is becoming support separation - the utmost substrate backwashed with a liquid jet. The Substrate is removed for further treatment. The sensory feedback for the Real separation of only one substrate is missing, no matter if in good or poor quality. Most likely will occurring break next to be dissolved substrate stick and continue together with this. This is the glued (good) substrate rejection, as it is not in the subsequent purification step from the fragments cleaned can be. The method is thus unsuitable for separation.

Die erfindungsgemäße Vorrichtung zum Vereinzeln und Sortieren eines Stapels scheibenförmiger Substrate besteht im Wesentlichen aus zwei Baugruppen. Eine vorgelagerte Baugruppe umfasst eine nicht erfinderische Anordnung zur Bereitstellung eines Stapels. Die Bereitstellung eines Stapels ist für die nachfolgende Vereinzelung von scheibenförmigen Substraten nötig. Die Form scheibenförmiger Substrate kann sowohl eckig als auch rund sein. Die Ausrichtung der scheibenförmigen Substrate kann vertikal oder horizontal vorliegen. Es kann daher nötig sein, den Stapel in die geeignete Position für die anschließende Vereinzelung zu bringen. Im Allgemeinen ist zunächst das Lösen von Teilstapeln aus einem größeren Stapel nötig. Es ist aber auch möglich, dass ein Stapel gegebener Länge bereits geeignet für die Vereinzelung ist.The inventive device for separating and sorting a stack of disc-shaped substrates consists essentially of two assemblies. An upstream module comprises a non-inventive arrangement for providing a Stack. The provision of a stack is for the subsequent separation of disc-shaped Substrates needed. The shape of disc-shaped substrates can be both angular and round. The orientation of the disc-shaped substrates can be vertical or horizontal. It may therefore be necessary the stack in the appropriate position for the subsequent separation bring to. In general, the first is the release of sub-stacks from a bigger pile necessary. But it is also possible that a stack of given length already suitable for the isolation is.
