Description
GEBIET DER ERFINDUNGFIELD OF THE INVENTION
Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren, um Wafer einer Flüssigkeit auszusetzen.The The present invention relates to an apparatus and a method around wafers of a liquid suspend.
STAND DER TECHNIKSTATE OF THE ART
Während der Herstellung von Solarzellenwafern ist es notwendig, die Wafer verschiedenen Flüssigkeiten auszusetzen, wie zum Beispiel Ätzlösungen, Spüllösungen, Waschen mittels Wasser usw.During the Production of solar cell wafers it is necessary to different the wafers liquids exposure, such as etching solutions, rinsing solutions Washing with water etc.
Es gibt verschiedene bekannte Verfahren und Vorrichtungen, um die Wafer einer Flüssigkeit auszusetzen. Heutzutage verwenden viele der Prozesse bei der Solarzellenwaferherstellung große, mit einer Flüssigkeit gefüllte Wannen, wo die Wafer in die Flüssigkeit eingetaucht werden. Viele Flüssigkeiten weisen eine relativ kurze Lebenszeit auf, was dazu führt, dass eine große Menge Flüssigkeit periodisch ersetzt werden muss, was umwelttechnisch und wirtschaftlich nicht gewünscht ist.It There are several known methods and devices to the wafers to expose to a liquid. Today, many of the processes use in solar cell wafer manufacturing size, with a liquid filled Tubs, where the wafers in the liquid be immersed. Many liquids have a relatively short lifetime, which leads to a large amount liquid must be periodically replaced, which environmentally and economically not wished is.
Des Weiteren gibt es eine Tendenz, die Wafer dünner zu machen, und folglich werden sie auch zerbrechlicher. Dünne Wafer sind auch leichter, und es besteht eine Gefahr, dass leichte, ein relativ großes Flächengebiet aufweisende Wafer tatsächlich in der Flüssigkeit treiben, was dazu führt, dass lediglich eine Fläche der Flüssigkeit ausgesetzt wird. Für eine Flüssigkeitsaussetzung, was eine Gasbildung in Kontakt mit Silikonwafern impliziert, ist dieses Problem sogar noch größer, weil sich Luftblasen an den Waferflächen ansammeln und zu einem weiteren Auftrieb beitragen.Of Further, there is a tendency to make the wafers thinner, and consequently they also become more fragile. Thin wafers are also lighter, and there is a danger that light, a relatively large area actually having wafers in the liquid drive what causes that only one area the liquid is suspended. For a fluid exposure, what implies gas formation in contact with silicon wafers is this problem is even bigger because Air bubbles on the wafer surfaces accumulate and contribute to a further boost.
Das Ziel der vorliegenden Erfindung ist es, eine Vorrichtung und ein Verfahren bereitzustellen, um Wafer einer Flüssigkeit auszusetzen, wobei das Volumen der Flüssigkeitswanne reduziert werden kann, wodurch der Gesamtverbrauch der Flüssigkeit reduziert wird. Darüber hinaus ist es ein Ziel der vorliegenden Erfindung, eine Vorrichtung und ein Verfahren bereitzustellen, bei dem dünnere Wafer derart sanft gehandhabt werden, dass ein Bruch vermieden wird. Weiter ist es wichtig, sicherzustellen, dass beide Flächen des Wafers der Flüssigkeit ausgesetzt werden. Schließlich ist es ein Ziel der vorliegenden Innovation, zerbrochene Wafer ohne ein Unterbrechen des Betriebs entfernen zu können.The The aim of the present invention is to provide a device and a Provide methods to suspend wafers of a liquid, wherein the volume of the liquid tank can be reduced, whereby the total consumption of the liquid is reduced becomes. About that In addition, it is an object of the present invention to provide a device and to provide a method in which thinner wafers are handled so gently be that a break is avoided. Next, it is important to ensure that both surfaces the wafer of the liquid get abandoned. After all It is a goal of the present innovation, broken wafer without to be able to remove an interruption of the operation.

Die zuvor erwähnte detaillierte Beschreibung ist speziell vorgesehen, bevorzugte Ausführungsformen der Erfindung zu illustrieren und zu beschreiben. Jedoch beschränkt die Beschreibung die Erfindung keineswegs auf besondere Ausführungsformen. Es sei angemerkt, dass es möglich wäre, mehrere Merkmale der vorigen, verschiedenen Ausführungsformen zu kombinieren.The previously mentioned Detailed description is specifically provided, preferred embodiments to illustrate and describe the invention. However, the limited The invention by no means refers to particular embodiments. It should be noted that it is possible would be several To combine features of the previous, various embodiments.
Bei den zuvor beschriebenen Ausführungsformen ist es deutlich, dass jeder Wafer separat durch die Haltevorrichtung gehalten wird. Darüber hinaus werden die Wafer während eines Transports durch die Flüssigkeit im Wesentlichen in einer horizontalen Position gehalten.at the embodiments described above It is clear that each wafer is separated by the holding device is held. About that In addition, the wafers are during a transport through the liquid held substantially in a horizontal position.
Zum Beispiel können alle zuvor beschriebenen Eintauchvorrichtungen und Transportvorrichtungen Perforationen, Siebe, Kanäle oder andere Öffnungen umfassen, damit die Flüssigkeit um die Wafer zirkulieren kann. Weiter können all die vorherigen Ausführungsformen Führungsmittel umfassen, um die Wafer durch die Flüssigkeit in Richtung des Pfeils A zu führen. Die Führungsmittel können an der Transportvorrichtung oder am Behälter befestigt sein.To the Example can all previously described immersion devices and transport devices Perforations, sieves, channels or other openings include, so that the liquid around the wafers can circulate. Next, all the previous embodiments guide means comprise the wafers through the liquid in the direction of arrow A. respectively. The guiding means can be attached to the transport device or the container.
Es sei angemerkt, dass die Flexibilität dünner Wafer ausgenutzt werden kann, um einen besseren Griff am Wafer zu erhalten. Dies wird erreicht, indem der Abstand zwischen den Haltevorrichtungen etwas kleiner gemacht wird als die Länge der Wafer, so dass der Wafer in einem gebogenen Zustand transportiert werden.It It should be noted that the flexibility of thin wafers are exploited can to get a better grip on the wafer. This is achieved by the distance between the holding devices slightly smaller is made as the length the wafer, so that the wafer is transported in a bent state become.
Darüber hinaus
wäre es
möglich,
die Wafer
In
Sehr dünne Wafer können dann potentiell brechen, wenn die relative Flüssigkeitsfluidstromgeschwindigkeit unterhalb und oberhalb des Wafers verschieden wird, und ein Druckunterschied über dem Wafer auftritt. Folglich können die Transportvorrichtung und die Haltevorrichtung derart ausgelegt und angeordnet sein, dass ein nahe-symmetrisches Flüssigkeitsstrommuster unterhalb und oberhalb des Wafers bereitgestellt wird. Zum Beispiel können Platten oberhalb und/oder unterhalb des Wafers oder ähnliche Mittel am Behälter fixiert sein, um den relativen Fluidstrom im Behälter zu steuern, während sich die Transportvorrichtung und die Haltevorrichtungen bewegen.Very thin wafers can then potentially break when the relative liquid fluid flow rate Below and above the wafer is different, and a pressure difference across the Wafer occurs. Consequently, you can the transport device and the holding device designed and be arranged that a near-symmetric liquid flow pattern below and provided above the wafer. For example, plates can above and / or below the wafer or similar means fixed to the container be to control the relative fluid flow in the container while move the transport device and the holding devices.
