Abstract
Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Prägen von Strukturen in ein Substrat unter geschützten Bedingungen, wie sie insbesondere bei optischen Datenträgern, Halbleiterstrukturen und Mikrostrukturen zu Anwendung kommen.The The invention relates to an embossing apparatus and method of structures in a substrate under protected conditions, as in particular with optical data carriers, semiconductor structures and microstructures are used.
Die Herstellung optischer Datenträger (z. B. CD, DVD) beinhaltet typischerweise einen Prägevorgang (engl. Embossing) zum Einprägen von Datenstrukturen in das Substrat. Um das geprägte Substrat frei von ungewollten Einschlüssen, z. B. Luftbläschen, zu halten, findet der Prägevorgang bei Unterdruck bzw. Vakuum statt. Herkömmliche Prägeanlagen realisieren den Unterdruck mittels einer weitgehend dichten Kammer, die zumindest die zwingend direkt beteiligten Komponenten der Prägevorrichtung vollständig umschließt. Diese Komponenten umfassen den Prägekopf mit dem daran befestigtem Stempel (engl. stamper), den diesem Prägekopf gegenüberliegenden Teil des typischerweise ebenen, glatten Trägers und das vor dem Prägen injizierte oder eingelegte formbare Substrat, das z. B. im Falle von optischen Datenträgern typischerweise aus Polycarbonat besteht. Der Träger dient als Unterlage und wird z. B. durch eine stabile Glasplatte gebildet. Die Oberfläche des Stempels, der am Prägekopf gehalten wird, weist viele kleinste Erhebungen auf, die als Negativ für die in den Rohling einzubringenden Vertiefungen (engl. pits) dienen, deren Anordnung die fest vorgegebenen Daten auf dem Datenträger repräsentiert.The Production of optical data carriers (eg CD, DVD) typically embossing for Imprinting data structures into the substrate. To the embossed Substrate free of unwanted inclusions, z. B. air bubbles, to hold, the stamping process takes place at negative pressure or Vacuum instead. Implement conventional embossing systems the negative pressure by means of a largely dense chamber, at least the mandatory directly involved components of the embossing device completely encloses. These components include the embossing head with the stamp attached to it (English stamper), this embossing head opposite part of the typically flat, smooth support and the moldable injected or inserted prior to embossing Substrate z. B. in the case of optical media typically made of polycarbonate. The carrier serves as a document and z. B. formed by a stable glass plate. The surface of the stamp, the stamping head has many smallest elevations that are considered negative for the recesses to be introduced into the blank (engl. Pits) whose arrangement the fixed data on the Represents disk.

Es ist Aufgabe der vorliegenden Erfindung, den Betrieb und/oder die Wartung zu beschleunigen. Diese Aufgabe wird mit den Merkmalen der Patentansprüche gelöst.It Object of the present invention, the operation and / or the Accelerate maintenance. This task is combined with the characteristics of Claims solved.
Bei der Lösung der Aufgabe geht die Erfindung von dem Grundgedanken aus, den Kammerdeckel als Prägekopf auszubilden und/oder eine selbstschließende Verbindung für den Vakuumanschluss einzusetzen. Ermöglicht wird dies durch eine verformbare Abdichtung zwischen dem Prägekopf und dem Substratträger bzw. durch eine trennbare selbstdichtende Vakuumkupplung im Vakuumkanal.at the solution of the problem, the invention of the basic idea from, the chamber lid form as embossing head and / or to use a self-closing connection for the vacuum connection. This is made possible by a deformable seal between the embossing head and the substrate carrier or by a separable self-sealing vacuum coupling in the vacuum channel.
Erfindungsgemäß kann auf die beweglichen, verschleißintensiven Vakuum-Durchführungen verzichtet werden. Die Befestigung der Hubachse und der optionalen Versorgungsanschlüsse erfolgt direkt an dem Prägekopf. Die Versorgungsanschlüsse können z. B. zum Abführen von Luft zum Ansaugen des Stampers an den Prägekopf bzw. dem Abblasen des geprägten Substrates vom Stamper dienen.According to the invention on the moving, wear-intensive vacuum feedthroughs be waived. The attachment of the lifting axis and the optional Supply connections are made directly at the embossing head. The supply connections can z. B. for removal air for sucking the stamper to the embossing head or serve to blow off the embossed substrate from the stamper.
Die Versorgungsanschlüsse und die Hub-Achse bzw. die Hub-Achsen können atmosphärenseitig und fest am Prägekopf angeordnet werden. Die Dichtungs-Membrane ermöglicht die Relativbewegung zwischen dem äußeren Ringflansch und dem Prägekopf mit Stempel während des Prägehubs (Embossing-Hub). Die erfindungsgemäße Lösung ist kostengünstig und ermöglicht eine gute Zugänglichkeit für Servicezwecke. Zudem ist das zu evakuierende Volumen deutlich reduziert, so dass die erforderliche Pumpzeit für die Vakuumerzeugung und damit die Produktionszykluszeit verringert werden kann; dadurch wird die Produktivität erhöht.The Supply connections and the hub axis or axes can atmosphere side and firmly at the embossing head to be ordered. The sealing membrane allows the Relative movement between the outer ring flange and the embossing head with punch during the embossing stroke (embossing stroke). The solution according to the invention is inexpensive and allows good accessibility for Service purposes. In addition, the volume to be evacuated is significantly reduced, so the required pumping time for the vacuum generation and thus the production cycle time can be reduced; thereby the productivity is increased.
Die erfindungsgemäße Vakuumkupplung erlaubt die Verwendung von ortsfesten Vakuum-Absperrventilen. Der federbelastete Kontaktkopf bewegt sich während des gesamten Prozesses zusammen mit dem Kammerdeckel bzw. dem äußeren Ringflansch, wobei die Vakuumanbindung über eine in Axialrichtung des Vakuumkanals flexible Verbindung erfolgt. Für einen Stamperwechsel oder zu Service-Zwecken am Prägekopf sind kein Werkzeug und kein zusätzlicher Antrieb für den Trenn- bzw. Verbindungsvorgang der Vakuumkupplung erforderlich. Beim Freifahren des Prägekopfes wird die Vakuumverbindung selbsttätig getrennt. Nach einer Schwenkbewegung, z. B. um 90°, ist der Prägekopf samt Stamper bequem von der Seite, z. B. zu Wartungszwecken, vollständig zugänglich.The Vacuum coupling according to the invention allows the use stationary vacuum shut-off valves. The spring-loaded contact head moves along with throughout the process the chamber lid or the outer annular flange, wherein the vacuum connection via a in the axial direction of Vacuum channel flexible connection takes place. For a stamper change or for service purposes on the embossing head are not a tool and no additional drive for the separation or Connection process of the vacuum coupling required. When freediving of the embossing head, the vacuum connection is self-acting separated. After a pivoting movement, z. B. by 90 °, is the embossing head velvet stamper comfortably from the side, z. B. for maintenance purposes, fully accessible.
