Description

Die Erfindung betrifft eine Strahlungsheizung mit einer hohen Infrarot-Strahlungsleistung für Bearbeitungskammern.The invention relates to a radiant heater with a high Infrared radiation power for processing chambers.

Derartige Strahlungsheizungen werden beispielsweise innerhalb von Bearbeitungskammern, z.B. Vakuumkammern, eingesetzt, um in einem vorgegebenen Arbeitsbereich eine erforderliche Arbeitstemperatur zu erzeugen. Derartige Temperaturen können im Strahlerbereich durchaus 3.000 °C erreichen, wobei bei großflächigen Arbeitsbereichen auch ein Strahlerarray zur Anwendung kommen kann, um über einen größeren Bereich eine gleichmäßige Arbeitstemperatur zu erreichen.Such radiant heaters, for example, within of processing chambers, e.g. Vacuum chambers, used to in a given working range a required working temperature to create. Such temperatures can in Spotlight range can reach 3,000 ° C, with large area Work areas also a spotlight array for use can come to a uniform over a larger area To reach working temperature.

Bei derartigen Strahlungsheizungen haben sich jedoch einige Nachteile herausgestellt, die deren Anwendung erheblich behindern. Dies ist einerseits das Problem, daß insbesondere bei Anwendungen im Vakuum bei hohen Betriebsspannungen elektrische Überschläge auftreten können. Diese Gefahr besteht insbesondere während des Evakuierungsvorganges. Andererseits können besonders hohe Arbeitstemperaturen bzw. Strahlungsleistungen mangels ausreichender Kühlung der Infrarotstrahler im Vakuum nicht realisiert werden können.In such radiant heaters, however, have some Disadvantages highlighted that significantly hinder their application. On the one hand, this is the problem, in particular in the case of Vacuum applications at high operating voltages electrical Flashovers may occur. This danger exists in particular during the evacuation process. On the other hand especially high working temperatures or radiant powers in the absence of adequate cooling of the infrared radiators in a vacuum can not be realized.

zur vermeidung von Überschlägen kann zwar die Spannung reduziert werden, jedoch läßt sich dann die geforderte Strahlungsleistung nicht erreichen. Außerdem besteht grundsätzlich die Möglichkeit, daß die Heizung während der Evakuierung der Vakuumkammer abgeschaltet wird. Dies führt aber zwangsläufig zu einer unerwünschten Erhöhung bzw. Verlängerung der Prozesszeit.
In der US-A-5 551 670 wird eine hochintensive Infrarot-Heizvorrichtung beschrieben, bei der die Lebensdauer der Infrarot-Strahler dadurch erhöht werden soll. Um dies zu erreichen, ist jeder Infrarot-Strahler in einem transparenten Quarz-Rohr angeordnet, durch das Kühlluft geleitet werden kann. Zu diesem Zweck sind Kupferröhrchen vorgesehen, die sich durch die elektrischen Anschlusskontakte der Infrarot-Strahler erstrecken. Um den Wirkungsgrad der Infrarot-Strahler nicht negativ zu beeinflussen, wird die Umgebungsluft erst bei Temperaturen über 1.500 °F (793 °C) in die Quarz-Rohre eingeleitet.
Weiterhin zeigt die EP-A-0 848 575 eine Heizvorrichtung mit einem Array von Wolfram-Halogen-Strahlern, die jeweils in einer konzentrischen Anordnung von Quarz-, Silizium- oder Saphir-Rohren angeordnet sind. Um die erzeugte Strahlung zu konzentrieren und in eine Vorzugsrichtung auszurichten, sind ist eines der Rohre mit einem Reflektor in Form von einer Goldbeschichtung versehen, die das Rohr teilweise umgibt. Schließlich wird in der US-A-5 196 674 ein Ofen mit einem Schutz für ein Heizelement beschrieben, das in einem Quarz-Rohr angeordnet ist. Der hier vorgesehene Schutz gegen Berührung besteht aus einem mehrfach geschlitzten u-förmigen Gehäuse aus Blech, welches das Quarz-Rohr in einem Abstand umgibt.
Der Erfindung liegt daher die Aufgabe zugrunde, eine vakuumtaugliche Strahlungsheizung zu realisieren, bei der die aufgezeigten Nachteile des Standes der Technik vermieden werden.
Although the voltage can be reduced to avoid flashovers, it is then not possible to achieve the required radiant power. In addition, there is basically the possibility that the heater is switched off during the evacuation of the vacuum chamber. However, this inevitably leads to an undesirable increase or prolongation of the process time.
US-A-5 551 670 describes a high-intensity infrared heater in which the life of the infrared emitters is thereby to be increased. To achieve this, each infrared emitter is arranged in a transparent quartz tube, through which cooling air can be passed. For this purpose, copper tubes are provided which extend through the electrical connection contacts of the infrared emitters. In order not to adversely affect the efficiency of the infrared radiator, the ambient air is introduced into the quartz tubes only at temperatures above 1500 ° F (793 ° C).
Furthermore, EP-A-0 848 575 shows a heater with an array of tungsten-halogen lamps, each arranged in a concentric arrangement of quartz, silicon or sapphire tubes. In order to concentrate and direct the generated radiation in a preferred direction, one of the tubes is provided with a reflector in the form of a gold coating which partially surrounds the tube. Finally, US-A-5,196,674 discloses an oven with protection for a heating element disposed in a quartz tube. The protection against contact provided here consists of a multiply slotted U-shaped housing made of sheet metal, which surrounds the quartz tube at a distance.
The invention is therefore based on the object to realize a vacuum-suitable radiant heating, in which the disadvantages of the prior art are avoided.

Die der Erfindung zugrundeliegende Aufgabe wird durch die Verwendung einer Strahlungsheizung mit einer hohen Infrarot-Strahlungsleistung, bei der die Infrarot-Strahlungseinheit aus einer Infrarot-Strahlungsquelle besteht, die innerhalb eines infrarot-strahlungsdurchlässigen Quarzglas-Rohres angeordnet ist, wobei die Infrarot-Strahlungsquelle in dem Quarzglas-Rohr mit einer Kühleinrichtung verbunden ist, die innerhalb des Quarzglas-Rohres einen Luftstrom erzeugt, wobei der Infrarot-Strahlungsquelle ein Strahlungsreflektor zugeordnet ist und wobei die Infrarot-Strahlungsquelle mit einer Energiequelle verbindbar ist in einer Vakuum-Kammer gelöst, bei der sich das Quarzglas-Rohr in die Vakuum-Bearbeitungs-kammer erstreckt und deren Wand zumindest mit einem Ende durchdringt und wobei der Innenraum der Quarzglas-Rohre gegenüber der Atmosphäre innerhalb der Vakuum-Bearbeitungskammer isoliert ist, indem die Durchgänge der Quarzglas-Rohre durch die Wand gasdicht abgedichtet sind. Um eine großflächige und gleichmäßige Bestrahlung zu realisieren, ist die Verwendung einer Strahlungsheizung mit einem Array von Infrarot-Strahlungseinheiten mit Infrarot-Strahlungsquellen vorgesehen, wobei jede Infrarot-Strahlungsquelle separat mit einer Energiequelle verbindbar ist, um eine einfache Anpassung der Strahlungsleistung an die jeweiligen Erfordernisse, z.B. durch Einschalten der jeweils benötigten Anzahl von Infrarot-Strahlungsquellen zu ermöglichen.
Durch die Erfindung wird ermöglicht, dass die Infrarot-Strahlungsquelle mit beliebigen Betriebsspannungen, also auch bei hohen Betriebsspannungen betrieben werden kann, ohne dass die Gefahr von elektrischen Überschlägen in der Bearbeitungskammer bestehen würde. Darüber hinaus ermöglicht die Erfindung das Erreichen besonders hoher Arbeitstemperaturen bzw. Strahlungsleistungen, da die Atmosphäre innerhalb des Rohres völlig unabhängig von der Atmosphäre in der Bearbeitungskammer ist.
Um dies realisieren zu können, ist das Array innerhalb der Bearbeitungskammer angeordnet, wobei jedes Rohr des Arrays wenigstens mit einem Ende durch die Wandung der Bearbeitungskammer geführt ist. In diesem Fall muss dann natürlich das sich in die Bearbeitungskammer erstreckende Ende jedes Rohres des Arrays verschlossen sein. Im Falle dass sich die Rohre des Arrays durch beidends durch die Wandung der Bearbeitungskammer erstrecken, können diese Rohre mit einem Kühlkreislauf verbunden werden, so dass das Kühlmedium durch die Rohre strömen kann.
The object underlying the invention is achieved by the use of a radiant heater with a high infrared radiation power, wherein the infrared radiation unit consists of an infrared radiation source, which is disposed within an infrared radiation-transmissive quartz glass tube, wherein the infrared radiation source in the Quartz glass tube is connected to a cooling device which generates an air flow within the quartz glass tube, wherein the infrared radiation source is associated with a radiation reflector and wherein the infrared radiation source is connectable to a source of energy dissolved in a vacuum chamber in which the Quartz glass tube extends into the vacuum processing chamber and penetrates the wall at least one end and wherein the interior of the quartz glass tubes to the atmosphere within the vacuum processing chamber is isolated by the passage of the quartz glass tubes sealed by the wall gas-tight are. In order to realize a large-scale and uniform irradiation, the use of a radiant heater with an array of infrared radiation units is provided with infrared radiation sources, each infrared radiation source is separately connectable to a power source to a simple adjustment of the radiation power to the respective requirements, eg by switching on the respectively required number of infrared radiation sources.
The invention makes it possible that the infrared radiation source with any operating voltages, so even at high operating voltages can be operated without the risk of electrical flashovers in the processing chamber would exist. Moreover, the invention makes it possible to achieve particularly high operating temperatures or radiation powers, since the atmosphere inside the tube is completely independent of the atmosphere in the processing chamber.
In order to be able to realize this, the array is arranged within the processing chamber, wherein each tube of the array is guided at least one end through the wall of the processing chamber. In that case, of course, the end of each tube of the array extending into the processing chamber must be closed. In the event that the tubes of the array extend through both sides of the wall of the processing chamber, these tubes can be connected to a cooling circuit, so that the cooling medium can flow through the tubes.

Der Strahlungsreflektor sollte gemeinsam mit der Infrarot-Strahlungsquelle 2 in dem Rohr 1 angeordnet werden, um unerwünschte thermische Effekte, oder auch eine Kontamination des Atmosphäre in der Bearbeitungskammer 3 zu vermeiden, die durch das Material des Strahlungsreflektors verursacht werden könnte.The radiation reflector should work together with the infrared radiation source 2 are arranged in the tube 1 to unwanted thermal effects, or even contamination to avoid the atmosphere in the processing chamber 3, the caused by the material of the radiation reflector could.

Es ist auch möglich, mehrere Rohre 1 mit Infrarot-Strahlungsquellen 2 zu einem Array anzuordnen, indem das Array innerhalb der Bearbeitungskammer 3 angeordnet wird, wobei jedes Rohr des Arrays beidends durch die Wandung 6 der Bearbeitungskammer 3 geführt ist. Jede der Infrarot-Strahlungsquellen 2 kann separat schaltbar mit einer Energiequelle verbunden sein. Das ermöglicht z.B. eine einfache Anpassung der Strahlungsleistung an die jeweiligen Erfordernisse. Damit wird über die gesamte Strahlerfläche des Arrays eine gleichmäßige Bestrahlung der zu bestrahlenden Objekte erreicht.It is also possible to use several tubes 1 with infrared radiation sources 2 to arrange an array by placing the array inside the processing chamber 3 is arranged, each tube of the Arrays at both ends through the wall 6 of the processing chamber. 3 is guided.
