Die Erfindung betrifft darüber hinaus eine Vorrichtung zum Bevorraten von mittels eines Beladeorganes in einen CVD-Reaktor bringbaren bzw. aus diesem entnehmbaren, ein oder mehrere Substrate tragenden Substrathalter in einer Bevorratungskammer.The invention further relates to a device for storing a substrate holder which can be brought into or removed from a CVD reactor by means of a loading element and which carries one or more substrates in a storage chamber.
Aus der
Die
Die
In einer MOCVD-Anlage zur Beschichtung von insbesondere III-V-Halbleitersubstraten mit Halbleiterschichten werden Substrathalter mit darauf aufliegenden Substraten in einer Bevorratungskammer, welche auch als Magazin oder Magazinkammer bezeichnet wird, bevorratet. Die Magazinkammer besitzt eine Vielzahl von übereinander angeordneten Etagen, wobei jede Etage einen Substrathalter aufnimmt. Die Substrathalter sind somit vertikal übereinander angeordnet. Mittels eines Greifers wird ein Substrathalter nach dem anderen aus der Bevorratungseinrichtung entnommen und in einen CVD-Reaktor gebracht. Der Boden der Prozesskammer des CVD-Reaktors wird von einem Substrathalterträger ausgebildet. Der im Wesentlichen kreisscheibenförmige Substrathalterträger besitzt eine Vielzahl von Ladepositionen, auf denen jeweils ein Substrathalter positionierbar ist. Die
Beim Stand der Technik werden die Substrathalter in der Bevorratungskammer in einer Kassette vertikal übereinanderliegend abgelegt. Zur Aufnahme je eines Substrathalters besitzt die Magazinkammer eine Höheneinheit von typischerweise 25 bis 30 cm. Da der vertikale Hub des Greifarms der Beladeeinrichtung begrenzt ist und außerdem die Beladung durch ein nach oben und nach unten beschränktes Beladetor erfolgt, besitzt die Bevorratungseinrichtung gemäß Stand der Technik einen Hubmechanismus, der es ermöglicht, die jeweilige Etage der Magazinkammer vor die Beladeöffnung zu positionieren.In the prior art, the substrate holders in the storage chamber are placed vertically one above the other in a cassette. To accommodate one substrate holder each, the magazine chamber has a height unit of typically 25 to 30 cm. Since the vertical stroke of the gripper arm of the loading device is limited and also the loading is carried out by an upwardly and downwardly limited Beladetor, the storage device according to the prior art has a lifting mechanism, which makes it possible to position the respective floor of the magazine chamber in front of the loading opening.
Der Erfindung liegt die Aufgabe zugrunde, die Qualität der hergestellten Halbleiterschichten zu erhöhen.The object of the invention is to increase the quality of the semiconductor layers produced.
Gelöst wird die Aufgabe durch die in den Ansprüchen angegebene Erfindung.The object is achieved by the invention specified in the claims.
Zunächst und im Wesentlichen ist vorgesehen, dass die Substrathalter horizontal nebeneinanderliegend in der Bevorratungskammer auf einer Magazinplatte angeordnet sind. Es handelt sich bevorzugt um eine im Wesentlichen runde Magazinplatte, die in ihrer Mitte eine Drehachse aufweist, so dass die Magazinplatte durch Drehen der Drehachse in verschiedene Be-/Entladepositionen gebracht werden kann, in denen jeweils ein Substrathalter vor einem Be-/Entladetor liegt. Die Magazinplatte kann den gleichen Durchmesser aufweisen, wie ein Substrathalterträger des zugehörigen MOCVD-Reaktors. Damit wird erreicht, dass auf der Magazinplatte dieselbe Anzahl von Substrathaltern abgelegt werden kann, wie auf den Substrathalterträger des CVD-Reaktors. Der freie Abstand oberhalb der Magazinplatte ist so gewählt, dass abhängig vom Totaldruck innerhalb der Bevorratungseinrichtung und der Gasart keine Konvektion stattfindet. Es entsteht praktisch kein Gasstrom der Partikel aufwirbelt. Die Magazinplatte ist wassergekühlt. Sie besitzt hierzu Kühlkanäle, durch die Kühlwasser strömt. Die Substrathalterträger können in Flächenkontakt auf der nach oben weisenden Oberfläche der Magazinplatte aufliegen. Bevorzugt liegen die Substrathalter jedoch auf wärmeisolierenden Abstandshaltern. Die Abstandshalter können eine ringförmige Gestalt aufweisen. Mit den Abstandshaltern werden die Substrathalter in einen definierten Abstand zur gekühlten Magazinplatte gehalten. Über den definierten Abstand erfolgt eine thermische Ankopplung der Substrathalter an die Magazinplatte. Der Wärmtransport und damit die Abkühlrate wird über die Distanzelemente definiert. Der Wärmetransport wird über die Eigenschaften eines Gaspolsters zwischen Oberseite der Magazinplatte und Unterseite des Substrathalterträgers definiert. Die Eigenschaften werden von der Art des Gases, also dessen spezifische Leitfähigkeit, dessen Totaldruck und der Höhe des Gasspaltes, der durch die Höhe der Distanzelemente definiert ist, gebildet. Der Spalt unter dem Substrathalter ist bevorzugt um mehr als einen Faktor 5 bis 10 kleiner als der Spalt oberhalb des Substrathalters. Der Wärmeleitungstransport erfolgt zumindest 90% über den unteren Spalt. Über den oberen Spalt werden maximal 10% der Wärme vom Substrathalter an die darüberliegende Decke abgegeben. In einer Weiterbildung der Erfindung ist vorgesehen, dass zwei oder mehrere Magazinplatten übereinander innerhalb der Bevorratungskammer angeordnet sind. Auch hier ist der freie Abstand über den Magazinplatten so gewählt, dass keine Konvektion stattfindet. Die Kühlung der Substrathalter erfolgt auch in diesem Fall durch Wärmeleitung. Durch die nahezu konvektionsfreie Kühlung werden keine Partikel mehr aufgewirbelt, die sich auf den Substratoberflächen ablagern können. Die Ausbeute an brauchbaren Bauelementen wird damit nicht mehr durch das Abkühlen der Substrathalter beeinträchtigt. Die Magazinplatte ist im Wesentlichen rund. Die Außenwand verläuft vorzugsweise aber nicht auf einer Kreisbogenlinie, sondern besitzt Auswölbungen bzw. Einbuchtungen, die insbesondere mit einer optischen Positioniereinrichtung abtastbar sind, um die Magazinplatte in den verschiedenen Be-/Entladestellungen zu positionieren. Hierdurch kann mittels eines Vakuumroboters auf alle Magazinplätze zugegriffen werden. Mit dem Greifarm des Vakuumroboters können die Substrathalter nacheinander der Magazinplatte entnommen werden und an Ladepositionen des Substrathalterträgers des CVD-Reaktors gebracht werden. Der Substrathalterträger des CVD-Reaktors wird hierzu ebenfalls schrittweise um eine Drehachse in verschiedene Be-/Entladepositionen gedreht. Nachdem der Substrathalterträger des CVD-Reaktors vollständig mit Substrathaltern beladen wird, wird ein Beladetor zwischen der Transferkammer und dem CVD-Reaktor geschlossen. Mittels eines Gaseinlassorganes wird dann nach einem vorangehenden Aufheizschritt ein aus mehreren reaktiven Gasen bestehendes Prozessgas in die Prozesskammer des CVD-Reaktors eingeleitet. Die Prozessgase zerlegen sich pyrolytisch an den Oberflächen des Substrats bzw. der Substrathalter und bilden eine III-V-Schicht auf den Substratoberflächen. Es können mehrere Schichten übereinander abgeschieden werden, ohne dass die Substrathalter zwischenzeitig der Prozesskammer entnommen werden. Nach Beendigung der Beschichtungsbehandlung innerhalb der Prozesskammer wird die Prozesskammer mit einem Inertgas, bspw. Wasserstoff oder Stickstoff, gespült. Die Prozesskammer wird geringfügig abgekühlt. Im noch heißen Zustand wird das Beladetor zwischen der Transferkammer und der Prozesskammer des CVD-Reaktors geöffnet. Mit dem Beladeorgan werden nacheinander die heißen Substrathalter aus der Prozesskammer entnommen und durch ein geöffnetes Beladetor auf die Magazinplatte abgesetzt. Diese wird zuvor derartig gedreht, dass ein freier Platz mit einem freien Distanzelement vor dem Beladetor liegt, auf welches der heiße Substrathalter aufgesetzt werden kann. Die Kühlung der Substrathalter erfolgt dann über Wärmeleitung zwischen der Unterseite des im Wesentlichen kreisscheiben-förmigen Substrathalters und der Oberseite der wassergekühlten Magazinplatte. Die thermische Ankopplung zwischen der gekühlten Magazinplatte und den Substrathaltern erfolgt über den durch das Distanzelement definierten Spalt und das Inertgas welches sich innerhalb der Bevorratungskammer befindet. Die Abkühlrate wird einerseits durch das Spaltmaß und andererseits durch die Wärmeleitfähigkeit des verwendeten Inertgases bestimmt. Der Druck innerhalb der Bevorratungskammer wird so eingestellt, dass sich oberhalb der Substrathalter nur die nicht vermeidbare minimale Konvektion einstellt. Der Abstand des Gasspalts oberhalb des Substrathalters ist entsprechend klein gewählt. Die charakteristischen Größen, Wärmeleitfähigkeit des Gases und Wärmeübergangskoeffizient sowie Weite des Gasspaltes, sind derart aufeinander abgestimmt, dass die charakteristische NUSSELT-Zahl etwa 1 beträgt. First and foremost, it is provided that the substrate holders are arranged horizontally next to one another in the storage chamber on a magazine plate. It is preferably a substantially round magazine plate having in its center an axis of rotation, so that the magazine plate can be brought by rotating the axis of rotation in different loading / unloading positions, in each of which a substrate holder is located in front of a loading / unloading. The magazine plate may have the same diameter as a substrate holder carrier of the associated MOCVD reactor. This ensures that the same number of substrate holders can be stored on the magazine plate as on the substrate holder carrier of the CVD reactor. The free space above the magazine plate is selected so that no convection takes place depending on the total pressure within the storage device and the gas type. There is virtually no gas flow of particles whirls up. The magazine plate is water cooled. It has cooling channels through which cooling water flows. The substrate holder carriers may be in surface contact on the upwardly facing surface of the magazine plate. However, the substrate holders are preferably on heat-insulating spacers. The spacers may have an annular shape. The spacers hold the substrate holders at a defined distance from the cooled magazine plate. Over the defined distance there is a thermal coupling of the substrate holder to the magazine plate. The heat transport and thus the cooling rate is defined by the spacer elements. The heat transfer is defined by the properties of a gas cushion between the top of the magazine plate and the underside of the substrate holder carrier. The properties are formed by the type of gas, ie its specific conductivity, its total pressure and the height of the gas gap, which is defined by the height of the spacer elements. The gap under the substrate holder is preferably smaller by more than a factor of 5 to 10 than the gap above the substrate holder. The heat conduction transport takes place at least 90% over the lower gap. A maximum of 10% of the heat is released from the substrate holder to the ceiling above it via the upper gap. In one development of the invention, it is provided that two or more magazine plates are arranged one above the other within the storage chamber. Again, the free space above the magazine plates is chosen so that no convection takes place. The cooling of the substrate holder also takes place in this case by heat conduction. Due to the almost convection-free cooling no particles are whirled up, which can be deposited on the substrate surfaces. The yield of useful devices is thus no longer affected by the cooling of the substrate holder. The magazine plate is essentially round. The outer wall preferably but not on a circular arc line, but has bulges or indentations, which can be scanned in particular with an optical positioning to position the magazine plate in the various loading / unloading. As a result, all magazine locations can be accessed by means of a vacuum robot. With the gripper arm of the vacuum robot, the substrate holder can be successively removed from the magazine plate and brought to loading positions of the substrate holder carrier of the CVD reactor. The substrate holder carrier of the CVD reactor is this also rotated stepwise about an axis of rotation in different loading / unloading positions. After the substrate holder carrier of the CVD reactor is completely loaded with substrate holders, a Beladetor between the transfer chamber and the CVD reactor is closed. By means of a gas inlet member, a process gas consisting of a plurality of reactive gases is then introduced into the process chamber of the CVD reactor after a preceding heating step. The process gases decompose pyrolytically on the surfaces of the substrate or the substrate holder and form a III-V layer on the substrate surfaces. Several layers can be deposited on top of each other without the substrate holders being temporarily removed from the process chamber. After completion of the coating treatment within the process chamber, the process chamber is purged with an inert gas, for example hydrogen or nitrogen. The process chamber is cooled slightly. When still hot, the loading gate between the transfer chamber and the process chamber of the CVD reactor is opened. With the loading member, the hot substrate holders are successively removed from the process chamber and deposited by an open Beladetor on the magazine plate. This is previously rotated such that a free space with a free spacer element in front of the Beladetor, on which the hot substrate holder can be placed. The cooling of the substrate holder then takes place via heat conduction between the underside of the substantially circular disk-shaped substrate holder and the upper side of the water-cooled magazine plate. The thermal coupling between the cooled magazine plate and the substrate holders via the gap defined by the spacer element and the inert gas which is located within the storage chamber. The cooling rate is determined on the one hand by the gap and on the other hand by the thermal conductivity of the inert gas used. The pressure within the storage chamber is adjusted so that only the unavoidable minimum convection is established above the substrate holder. The distance of the gas gap above the substrate holder is selected to be correspondingly small. The characteristic quantities, the thermal conductivity of the gas and the heat transfer coefficient as well as the width of the gas gap, are coordinated so that the characteristic NUSSELT number is about 1.
