Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrich tung zum reaktiven Beschichten eines Substrats, bei spielsweise mit Siliziumdioxid (SiO2), bestehend aus einer Stromquelle, welche mit einer in einer evakuier baren Beschichtungskammer angeordneten Elektrode ver bunden ist, die elektrisch mit einem Target in Verbin dung steht, das zerstäubt wird und dessen zerstäubte Teilchen sich auf dem Substrat niederschlagen, wobei in die Beschichtungskammer ein Prozeßgas einbringbar ist. The invention relates to a method and a device for the reactive coating of a substrate, for example with silicon dioxide (SiO 2 ), consisting of a current source which is connected to an electrode arranged in an evacuable coating chamber, which is electrically connected to a target in conjunction is standing, which is atomized and whose atomized particles are deposited on the substrate, a process gas being able to be introduced into the coating chamber.
Bei bekannten Verfahren zum Beschichten von Substraten mit Hilfe von Kathodenzerstäubung und Materialien mit einer hohen Affinität zum Reaktivgas besteht das Problem, daß nebem dem Substrat selbst auch Teile der Vorrichtung, wie die Innenwand der Prozeßkammer oder Teile von Blenden mit elektrisch nicht oder schlecht leitenden Materialien beschichtet werden, was die häufige Änderung der Prozeßparameter während eines einzigen Beschichtungsprozesses oder auch eine häufige Unterbrechung des Prozesses und auch eine häufige Reinigung oder einen Austausch von Teilen der Vorrich tung erforderlich macht.In known methods for coating substrates with the help of cathode sputtering and materials there is a high affinity for reactive gas Problem that in addition to the substrate itself, parts of the Device such as the inner wall of the process chamber or Parts of panels with electrical not or bad conductive materials are coated what the frequent change of process parameters during a single coating process or a common one Process interruption and also a frequent Cleaning or replacing parts of the device necessary.
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zum Sputtern von Materialien mit hoher Affinität zu einem Reaktivgas zu schaffen, das einen gleichmäßigen bzw. stabilen Prozeß ermöglicht und eine Reinigung der Teile der Vorrichtung überflüssig macht, und zwar ohne daß herkömmliche bzw. bereits vorhandene Vorrichtungen oder Anlagen hierfür ungeeignet sind bzw. ohne daß an diesen wesentliche oder kostspielige Umbauten oder Änderungen vorgenommen werden müssen.The present invention is therefore based on the object based, an apparatus and a method for Sputtering materials with high affinity for one To create reactive gas that is uniform or stable process and cleaning of the parts makes the device superfluous, without conventional or existing devices or Systems are unsuitable for this or without this significant or costly conversions or changes must be made.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das zu zerstäubende Target mehrteilig ist, wobei ein mittiger, dem Substrat gegenüberliegender Teil des Tar gets aus einem reaktiveren Material gebildet ist als der diesen mittigen Teil umschließenden oder einrahmen den Teil, wobei zwischen dem Substrat einerseits und dem mehrteiligen Target andererseits eine Blende vorge sehen ist mit einer zentralen Öffnung, die etwa die Konfiguration des mittleren Targetteils aufweist und wobei die Konfiguration des Magnetfelds der Elektrode während des Beschichtungsvorgangs ein Sputtern des reaktiveren Targetmaterials im oxidischen und des weniger reaktiven Targetmaterials im metallischen Mode bewirken. Weitere Einzelheiten und Merkmale sind in den anhängenden Ansprüchen näher gekennzeichnet.This object is achieved in that the target to be atomized is in several parts, with a central part of the tar opposite the substrate gets is made of a more reactive material than that enclose or frame this central part the part, between the substrate on the one hand and the multi-part target, on the other hand, an aperture see with a central opening that is about the same Configuration of the middle target part and the configuration of the magnetic field of the electrode sputtering of the coating during the coating process more reactive target material in oxidic and des less reactive target material in metallic fashion cause. Further details and features are in the attached claims characterized.
Die Erfindung läßt die verschiedensten Ausführungsmög lichkeiten zu; eine davon ist in der anhängenden Zeich nung schematisch näher dargestellt, die den Schnitt durch eine Sputteranlage mit einer Magnetron-Sputter kathode zeigt.The invention allows a wide variety of designs opportunities to; one of them is in the attached drawing voltage shown schematically, the cut through a sputtering system with a magnetron sputter cathode shows.
In der Zeichnung ist ein Substrat 1 dargestellt, daß mit einer dünnen Schicht 2 aus einem Oxid (z. B. Sili ziumdioxid oder Aluminiumoxid) versehen werden soll. Diesem Substrat 1 liegt ein mehrteiliges Target 3 gegenüber, das zu zerstäuben ist. Das Target 3 steht über eine Platte 4 mit einer Elektrode 5 in Verbindung, die auf einem Joch 6 ruht, welches zwischen sich und dem Element 4 fünf Magnete 7, 8, 9, 30, 31 einschließt.In the drawing, a substrate 1 is shown that is to be provided with a thin layer 2 made of an oxide (e.g. silicon dioxide or aluminum oxide). This substrate 1 is opposite a multi-part target 3 , which is to be atomized. The target 3 is connected via a plate 4 to an electrode 5 , which rests on a yoke 6 , which includes five magnets 7 , 8 , 9 , 30 , 31 between it and the element 4 .
Die auf das Target 3 gerichteten Polaritäten der Pole der fünf Magnete wechseln sich ab, so daß jeweils die Südpole der beiden äußeren Magnete 30, 31 mit den Nordpolen der innenliegenden Magnete 7, 9 etwa kreis bogenförmige Magnetfelder durch das Target 3 bewirken. Diese Magnetfelder verdichten das Plasma vor dem Target 3, so daß sie dort, wo die Magnetfelder das Maximum ihrer Kreisbögen besitzen, ihre größte Dichte haben. Die Ionen im Plasma werden durch ein elektrisches Feld beschleunigt, das sich aufgrund einer Gleichspannung aufbaut, die von einer Gleichstromquelle 10 angegeben wird. Diese Gleichstromquelle 10 ist mit ihrem negati ven Pol über zwei Induktivitäten 11, 12 mit der Elek trode 5 verbunden. Das elektrische Feld steht senkrecht auf der Oberfläche des Targets 3 und beschleunigt die positiven Ionen des Plasmas in Richtung auf dieses Target 1. Hierdurch werden mehr oder weniger viele Atome oder Partikel aus dem Target 3 herausgeschlagen, und zwar insbesondere aus den Gebieten 13, 14, 32, 33, wo die Magnetfelder ihre Maxima haben. Die zerstäubten Atome oder Partikel wandern vorwiegend in Richtung auf das Substrat 1 zu, wo sie sich als dünne Schicht 2 niederschlagen.The polarities of the poles of the five magnets directed at the target 3 alternate, so that the south poles of the two outer magnets 30 , 31 with the north poles of the inner magnets 7 , 9 cause approximately circular arc-shaped magnetic fields through the target 3 . These magnetic fields compress the plasma in front of the target 3 , so that they have their greatest density where the magnetic fields have the maximum of their arcs. The ions in the plasma are accelerated by an electric field that builds up on the basis of a direct voltage that is indicated by a direct current source 10 . This DC power source 10 is connected to its negative pole via two inductors 11 , 12 with the electrode 5 . The electric field is perpendicular to the surface of the target 3 and accelerates the positive ions of the plasma towards this target 1 . As a result, more or fewer atoms or particles are knocked out of the target 3 , in particular from the areas 13 , 14 , 32 , 33 , where the magnetic fields have their maxima. The atomized atoms or particles migrate predominantly towards the substrate 1 , where they are deposited as a thin layer 2 .
Das Target 3 besteht aus einem mittleren Teil 3a aus einem Material hoher Affinität zum Reaktivgas, bei spielsweise Si, und einem rahmenförmigen Teil 3b aus einem Material geringer Affinität zum Reaktivgas, bei spielsweise Sn. Während des Sputterprozesses tragen diese Konfiguration und Werkstoffauswahl und entspre chende Magnetfelder und ein abgestimmtes Verhältnis von Sauerstoff zu Argon dafür Sorge, daß sich an der Blende 24 vorwiegend das Sn als elektrisch leitender Werkstoff niederschlägt, während sich die Schicht 2 auf dem Sub strat 1 überwiegend aus reinem SiO2 (Silixiumdioxid) aufbaut.The target 3 consists of a central part 3 a made of a material with high affinity for the reactive gas, for example Si, and a frame-shaped part 3 b made of a material with low affinity for the reactive gas, for example Sn. During the sputtering process, this configuration and material selection and corresponding magnetic fields and a coordinated ratio of oxygen to argon ensure that the Sn 24 predominantly precipitates as an electrically conductive material, while the layer 2 on the substrate 1 predominantly consists of pure SiO 2 (silicon dioxide) builds up.
Für die Steuerung der dargestellten Anordnung kann ein Prozeßrechner vorgesehen werden, der Meßdaten verarbei tet und Steuerungsbefehle abgibt. Diesem Prozeßrechner können beispielweise die Werte des gemessenen Partial drucks in der Prozeßkammer 15, 15a zugeführt werden. Aufgrund dieser und anderer Daten kann er zum Beispiel den Gasfluß aus den Behältern 16, 17 über die Ventile 18, 19 regeln und die Spannung an der Kathode 5 ein stellen. Der Prozeßrechner ist auch in der Lage, alle anderen Variablen, z. B. Kathodenstrom und magnetische Feldstärke, zu regeln. Da derartige Prozeßrechner bekannt sind, wird auf eine Beschreibung seines Aufbaus verzichtet.For the control of the arrangement shown, a process computer can be provided which processes measured data and issues control commands. For example, the values of the measured partial pressure in the process chamber 15 , 15 a can be supplied to this process computer. Based on this and other data, he can, for example, regulate the gas flow from the containers 16 , 17 via the valves 18 , 19 and set the voltage at the cathode 5 . The process computer is also able to control all other variables, e.g. B. cathode current and magnetic field strength to regulate. Since such process computers are known, a description of their structure is omitted.
Die bei der beschriebenen Vorrichtung während des Be schichtungsvorgangs auf der Umgebung der Kathode - ins besondere der Innenseite der Blende 24 - aufgebrachte, vorwiegend metallische (und damit elektrisch leitende) Schicht trägt dafür Sorge, daß sämtliche Ladungsträger aus der Vakuum- bzw. Sputterkammer 25 abgeführt werden, wodurch dann ein stabiler Sputterprozeß bewirkt wird.The in the device described during the loading process on the area around the cathode - in particular the inside of the screen 24 - applied, predominantly metallic (and thus electrically conductive) layer ensures that all charge carriers are removed from the vacuum or sputtering chamber 25 be, which then causes a stable sputtering process.
