Der Aufbau dieser Spiegelfacetten ist relativ aufwendig, so dass derartige Facettenspiegelanordnungen einen erhöhten Justageaufwand bedeuten und relativ teuer sind.The structure of these mirror facets is relatively complex, so that such facet mirror arrangements an elevated Adjustment effort mean and are relatively expensive.
Facettenspiegel müssen hohe thermische Belastungen durch die absorbierte Strahlung, welche im Bereich des extremen Ultravioletts anzuordnen ist, standhalten, wobei diese Anordnung wohl nur in geringem Maße die hohe Anforderung hinsichtlich der thermischen Belastungen erfüllen.Faceted mirrors have high thermal loads by the absorbed radiation, which is in the range of the extreme Ultraviolet to be arranged withstand this arrangement probably only to a small extent meet the high requirements with regard to thermal loads.
Demgemäß ist es Aufgabe der Erfindung, einen Facettenspiegel für derartige Einsatzzwecke, insbesondere für Ultrahochvakuumanforderungen, zu optimieren und einen Aufbau zu schaffen, welcher mit möglichst wenig Teilen auskommt, einen sicheren, über einen langen Zeitraum stabilen und einfachen Aufbau gewährleistet.Accordingly, it is an object of the invention a faceted mirror for such uses, especially for ultra high vacuum requirements optimize and create a structure that works with few parts, a safe, stable over a long period of time and simple construction guaranteed.

- b) in einem zweiten Verfahrensschritt die Winkelabweichung der optischen Achse der Spiegelfläche jeder der Spiegelfacetten gegenüber der Normalen der Spiegelfacette ermittelt wird, wonach
- c) in einem dritten Verfahrensschritt in Kenntnis der im zweiten Verfahrensschritt ermittelten Messwerte für jede der Spiegelfacetten eine Aufnahmebohrung in einer Trägerplatte eingebracht wird, und wobei die Aufnahmebohrung hinsichtlich der zu erzielenden Winkelstellung bereits um den im zweiten Verfahrensschritt gemessenen Messwert korrigiert wird, wonach anschließend
- d) die Spiegelfacetten in die für die jeweilige Spiegelfacette vorgesehene Aufnahmebohrung eingesetzt werden, wonach
- e) eine erneute Messung der Ausrichtung der Spiegeloberfläche für jede der Spiegeloberflächen erfolgt und
- f) abschließend eine Nachbearbeitung der Spiegeloberfläche der Spiegelfacette zum Erzielen der endgültig geforderten Winkelgenauigkeit erfolgt.
- a) in a first process step, the mirror facets are manufactured, after which
- b) in a second method step, the angular deviation of the optical axis of the mirror surface of each of the mirror facets compared to the normal of the mirror facet is determined, after which
- c) in a third method step, knowing the measured values determined in the second method step, a receiving bore is made in a carrier plate for each of the mirror facets, and the receiving bore is already corrected with respect to the angular position to be achieved by the measured value measured in the second method step, after which
- d) the mirror facets are inserted into the mounting hole provided for the respective mirror facet, after which
- e) the alignment of the mirror surface is measured again for each of the mirror surfaces and
- f) finally, the mirror surface of the mirror facet is reworked to achieve the final required angular accuracy.
Die Aufgabe wird bezüglich des Verfahrens zur Bearbeitung der Aufnahmebohrungen durch die kennzeichnenden Merkmale von Anspruch 6 gelöst.The task is regarding the Procedure for machining the mounting holes by the characteristic Features of claim 6 solved.
Die Aufgabe wird bezüglich des Facettenspiegel durch die kennzeichnenden Merkmale von Anspruch 10 gelöst.The task is regarding the Faceted mirror through the characteristic features of claim 10 solved.
Um die erforderliche Genauigkeit zu erreichen, wird bei der Fertigung schrittweise vorgegangen. Zunächst werden die Einzelfacetten auf den bestmöglichen Winkelfehler von ca. 200" gefertigt. Diese Abweichung wird danach mit einem Winkelmessgerät, vorzugsweise mit einem Autokollimationsfernrohr mit Positioniertisch, ermittelt. Die Aufnahmebohrungen für die Spiegelfacetten werden nun mit bestmöglichster Fertigungsgenauigkeit, welche hier z.B. 50" beträgt, in die Trägerplatte eingebracht. Dabei ist bereits festgelegt worden, welche der Spiegelfacetten mit welchem der zuvor gemessenen Winkelfehler in welche der Aufnahmebohrungen eingesetzt wird. Die Aufnahmebohrungen können daher entsprechend dem gemessenen Winkelfehler der Spiegelfacetten bereits korrigiert werden. Der Restfehler nach dem Einsetzen der Spiegelfacetten in die jeweiligen Aufnahmebohrungen wird wiederum über ein Winkelmessgerät bestimmt. Dieser Fehler liegt aufgrund der zu erzielenden Fertigungsgenauigkeiten in einem Bereich, welcher es zulässt, den Restfehler über ein Oberflächenpräzisionsbearbeitungsverfahren zu korrigieren.To the required accuracy To achieve this, the manufacturing process is carried out step by step. First of all the individual facets to the best possible Angular error of approximately 200 "manufactured. This Deviation is then with an angle measuring device, preferably with an autocollimation telescope with positioning table, determined. The mounting holes for the mirror facets are now using the best possible Manufacturing accuracy, which here e.g. Is 50 "in the carrier plate brought in. It has already been determined which of the mirror facets with which of the previously measured angular errors in which of the receiving bores is used. The mounting holes can therefore be according to the measured angular errors of the mirror facets can already be corrected. The remaining error after inserting the mirror facets into the respective Location holes are in turn over a angle meter certainly. This error is due to the manufacturing accuracy to be achieved in an area that allows the residual error over a surface precision machining process to correct.
So lässt sich die erforderliche Qualität hinsichtlich der Ausrichtung der einzelnen Spiegelfacetten erzielen. Die Spiegelfacetten sind dann fest mit der Trägerplatte verbunden, so dass eine auch über einen langen Zeitraum stabile Ausrichtung gewährleistet ist. Außerdem wird durch den direkten Kontakt der Spiegelfacette mit der Trägerplatte ein Aufbau erreicht, welcher die von den Spiegelfacetten absorbierte Wärme ideal ableitet. Damit ist ein einfacher, kostengünstiger, sehr stabiler, schockunempfindlicher, materialreduzierender, klebstoffreier und thermisch unproblematischer Aufbau eines Facettenspiegels im Ultrahochvakuumbereich, insbesondere für den Einsatz in der EUV-Lithographie, möglich.This enables the required quality with regard to the alignment of the individual mirror facets to be achieved. The mirror facets are then firmly connected to the carrier plate, so that stable alignment is ensured even over a long period of time. In addition, the direct contact of the mirror facet with the carrier plate creates a structure enough to ideally dissipate the heat absorbed by the mirror facets. This enables a simple, inexpensive, very stable, shock-resistant, material-reducing, adhesive-free and thermally unproblematic construction of a facet mirror in the ultra-high vacuum range, in particular for use in EUV lithography.
Das Verfahren zur Herstellung von Facettenspiegeln besitzt gegenüber Lösungen mit Einzelmanipulatoren nicht nur Vorteile hinsichtlich einem geringeren Montage- und Justageaufwand und einer kostengünstigeren Herstellung, sondern dieses Verfahren erlaubt es auch, wesentlich kleinere Facettenspiegel herzustellen und in vielfacher Ausführung in einem Facettenspiegel anzuordnen, wobei ein Durchmesserbereich der Spiegelfacetten von 3 mm bis 50 mm ohne Schwierigkeiten realisierbar ist.The process of making Faceted mirror has opposite solutions with individual manipulators not only advantages in terms of a lower one Assembly and adjustment effort and a cheaper production, but this procedure also allows much smaller facet levels to manufacture and in multiple versions in a faceted mirror to be arranged, a diameter range of the mirror facets of 3 mm to 50 mm can be realized without difficulty.
In vorteilhafter Weise kann vorgesehen sein, dass die Bearbeitung der Spiegelfacette über Ion Beam Figuring (IBF) erfolgt. Der dafür notwendige Abtrag von typischerweise 1 μm bis 2 μm, wobei bis maximal 5 μm ohne Einbußen hinsichtlich der Oberflächenrauhigkeit der bearbeiteten Fläche möglich sind, kann dabei in einem Bearbeitungsschritt durchgeführt werden.Can advantageously be provided be that the processing of the mirror facet via Ion Beam Figuring (IBF) he follows. The one for it necessary removal of typically 1 μm to 2 μm, with a maximum of 5 μm without any loss in terms of the surface roughness the machined area possible are, can be carried out in one processing step.
In erfindungsgemäßer Weiterbildung kann ferner vorgesehen sein, dass die Bearbeitung der Spiegelfacette über das Aufdampfen von vorzugsweise keiligen Metallzwischenschichten erfolgt. Dieser Bearbeitungsschritt stellt eine Alternative zur IBF-Bearbeitung dar.In a further development according to the invention can also be provided that the processing of the mirror facet on the Evaporation of preferably wedge-shaped metal intermediate layers takes place. This processing step represents an alternative to IBF processing represents.
In erfindungsgemäßer Ausgestaltung kann vorgesehen sein, dass in einem ersten Verfahrensschritt die Aufnahmebohrungen mit einer Fertigungsgenauigkeit von 30" gefertigt werden, wonach in einem zweiten Verfahrensschritt die Aufnahmebohrungen an definierten Führungsflächen und Auflageflächen zur Erzielung der geforderten Genauigkeit über IBF bearbeitet werden.In an embodiment according to the invention, it can be provided be that the receiving holes in a first process step be manufactured with a manufacturing accuracy of 30 ", after which in a second Process step the receiving holes on defined guide surfaces and support surfaces processed to achieve the required accuracy via IBF.
