Description
Die vorliegende Erfindung betrifft eine IGBT-Anordnung mit Reverse-Diodenfunktion nach dem Oberbegriff des Patentanspruchs 1 bzw. 10 bzw. 11 bzw. 14.The The present invention relates to an IGBT device with reverse diode function according to the preamble of claim 1 or 10 or 11 or 14th
Bei zahlreichen Anwendungen von IGBTs wird eine Reverse-Diode benötigt, damit der IGBT in der gewünschten Weise arbeitet. Weil nun ein IGBT an sich selbst keine solche Reverse-Diode hat, wird gewöhnlich zusätzlich zum IGBT eine gesonderte Diode vorgesehen. Als Beispiel hierfür sei auf die US 2002/0 153 586 A1 verwiesen. Dort liegen ein IGBT und eine Reverse-Diode antiparallel zueinander in einem Halbleiterkörper und sind dabei durch eine in einen Graben eingebrachte Isolatorschicht elektrisch voneinander getrennt.at Numerous applications of IGBTs require a reverse diode in order to the IGBT in the desired Way works. Because now an IGBT in itself no such reverse diode usually becomes additionally for IGBT a separate diode provided. As an example, be on US 2002/0153 586 A1. There are an IGBT and a Reverse diode antiparallel to each other in a semiconductor body and are by an insulator layer introduced into a trench electrically isolated from each other.
Weiterhin ist aus IEEE Electron Device Letters, Band 23, Nr. 9, September 2002, Seiten 562 bis 564 ein DMOS-Feldeffekttransistor bekannt, zu dem in einem Halbleiterkörper zur Verbesserung des Schaltverhaltens eine Reverse-Diode antiparallel geschaltet ist.Farther is from IEEE Electron Device Letters, Vol. 23, No. 9, September 2002, pages 562 to 564 discloses a DMOS field effect transistor, to that in a semiconductor body To improve the switching behavior of a reverse diode antiparallel is switched.

Bestehende IGBTs liegen gewöhnlich in Vertikalstruktur vor. Bei diesen ist dann die Reverse-Diode in diese Vertikalstruktur in den Halbleiterkörper parallel zum IGBT vorgesehen.existing IGBTs are usually in vertical structure. These are then the reverse diode in this vertical structure is provided in the semiconductor body parallel to the IGBT.
Nun sind aber besonders für Ströme, deren Stromstärke unterhalb von 1A liegt, Lateralstrukturen von besonderem Vorteil. Bei diesen braucht nämlich nur eine Seite des Halbleiterkörpers, also in der Regel einer Siliziumscheibe, bearbeitet zu werden. Derartige Lateralstrukturen von IGBTs sind seit längerem üblich.Now but are especially for currents their current strength Below 1A, lateral structures are of particular advantage. For these only needs one side of the semiconductor body, So usually a silicon wafer, to be processed. such Lateral structures of IGBTs have long been common.

Es ist daher Aufgabe der vorliegenden Erfindung, eine IGBT-Anordnung zu schaffen, die bei einfachem Aufbau eine Reverse-Diodenfunktion hat und gegebenenfalls ohne weiteres in Lateralstruktur mit einem Hochvolt-Feldplattenrand gebildet werden kann.It It is therefore an object of the present invention to provide an IGBT arrangement, which has a reverse diode function with a simple structure and optionally readily in lateral structure with a high-voltage field plate edge can be formed.
Diese Aufgabe wird erfindungsgemäß durch eine IGBT-Anordnung mit den Merkmalen des Patentanspruchs 1 bzw. 10 bzw. 11 bzw. 14 gelöst.These The object is achieved by a IGBT arrangement with the features of claim 1 or 10 or 11 or 14 solved.
Dieser Thyristor kann in Lateralstruktur vorgesehen sein oder aber derart gestaltet sein, dass er in verpolter bzw. umge kehrt gepolter Richtung bei kleiner Spannung zündet und als Diode arbeitet. In letzterem Fall liegt also ein entarteter Thyristor vor, der infolge seiner verpolten Richtung "über Kopf" zündet.This thyristor may be provided in lateral structure or else designed such that it ignites in reverse polarity or reversed polarity at low voltage and works as a diode. In the latter case, there is a degenerate thyristor, which due to its reverse polarity "overhead" ignites.
Zunächst soll auf den IGBT mit dem Thyristor in Lateralstruktur näher eingegangen werden. Bei einer solchen IGBT-Anordnung wird deren Rand durch die Anodenzone gebildet. Ein Teil von dieser Anodenzone ist als Reverse-Thyristor ausgebildet. Dieser Reverse-Thyristor weist beispielsweise eine n+-leitende Anodenzone auf, die in einer p-leitenden Zone liegt, welche einen Rand der IGBT-Anordnung bildet und so ringförmig gestaltet ist. Diese ringförmige p-leitende Zone ist im n–-leitenden Halbleiterkörper von einer n-leitenden, ebenfalls ringförmigen Zone umgeben, welche einen Feld-Stopp-Ring im Randbereich der IGBT-Anordnung darstellt. Zwischen diesen beiden ringförmigen Zonen ergibt sich dann eine Zenerdiode, die bei der IGBT-Anordnung den Reverse-Stromeinsatzpunkt festlegt.First, the IGBT with the thyristor in lateral structure will be discussed in more detail. In such an IGBT arrangement, its edge is formed by the anode zone. Part of this anode zone is designed as a reverse thyristor. This reverse thyristor has, for example, an n + -type anode region which lies in a p-conducting zone, which forms an edge of the IGBT arrangement and is thus designed annular. This annular p-type region is surrounded in the n - -type semiconductor body by an n-type, likewise annular zone, which represents a field-stop ring in the edge region of the IGBT arrangement. Between these two annular zones then results in a zener diode, which defines the reverse current application point in the IGBT arrangement.
Die in der oben dargestellten Weise aufgebaute IGBT-Anordnung ist besonders vorteilhaft bei Lampenvorschaltgeräten anwendbar.The The IGBT arrangement constructed in the above-described manner is particularly advantageous applicable to lamp ballasts.
Es sei noch angemerkt, dass in dem eine Basiszone bildenden n–-leitenden Halbleiterkörper die effektive Lebensdauer der Ladungsträger durch die Dicke dieses Halbleiterkörpers, also etwa durch Dünnschleifen der entsprechenden Halbleiterscheibe und/oder durch Präparation der Rückseite, also durch deren Gestaltung mittels einer Metallschicht oder eines Schottky-Überganges usw., beliebig verändert bzw. beeinflusst werden kann. Wird in der ringförmigen Feldstoppzone die Dotierungskonzentration vermindert, so kann die Zenerspannung der durch die beiden ringförmigen Zonen gebildeten Zenerdiode vermindert werden. Schließlich kann durch ein "Punch-Through" (Durchbruch) im Reversebetrieb der IGBT-Anordnung deren Stromeinsatzpunkt praktisch beliebig klein gemacht werden.It should also be noted that in the n - type semiconductor body forming a base zone, the effective lifetime of the charge carriers is determined by the thickness of this semiconductor body, that is to say by thin grinding of the corresponding semiconductor wafer and / or by preparation of the rear side, ie by their design by means of a metal layer or a Schottky junction, etc., can be changed or influenced as desired. If the doping concentration is reduced in the annular field stop zone, the Zener voltage of the Zener diode formed by the two annular zones can be reduced. Finally, by a "punch-through" (reverse) in the reverse operation of the IGBT arrangement whose Stromeinsatzpunkt be made practically arbitrarily small.
Bei
der IGBT-Anordnung mit entartetem Thyristor weist der IGBT vorzugsweise
eine NPT-Struktur auf (vergleiche hierzu auch
In einem anderen Ausführungsbeispiel ist es möglich, die Rückseite des Halbleiterkörpers vor dessen Metallisierung zu maskieren und über die Maske in die Rückseite des Halbleiterkörpers übereinander und in Abstand voneinander eine n+-leitende Zone, eine p+-leitende Zone und eine weitere n+-leitende Zone durch Implantation und Ausheilen einzubringen. Ein "Punch-Through" durch die in die Oberfläche des Halbleiterkörpers eingebrachte n+-leitende Zone bewirkt dann eine "Überkopf-Zündung" in Reverserichtung der IGBT-Anordnung. Die Dotierung der p+-leitenden Zone sollte dann allerdings eine Dosis haben, die unterhalb 1012 cm–2 liegt. Ein geeigneter Dotierstoff hierfür ist Bor.In another embodiment, it is possible to mask the rear side of the semiconductor body prior to its metallization and via the mask in the back of the semiconductor body one above the other and at a distance from each other an n + -type zone, a p + -type zone and another n + - introduce conductive zone by implantation and healing. A "punch-through" through the introduced into the surface of the semiconductor body n + -type region then causes an "overhead ignition" in the reverse direction of the IGBT arrangement. However, the doping of the p + -type zone should then have a dose that is below 10 12 cm -2 . A suitable dopant for this is boron.
Ein Herstellungsverfahren für die erfindungsgemäße IGBT-Anordnung sieht für das an vorletzter Stelle genannte Ausführungsbeispiel vor, dass zunächst der NPT-IGBT bis zu dessen Metallisierung in üblicher Weise hergestellt wird. Sodann werden durch maskierte Ionenimplantationen die beiden n+- bzw. p+-leitenden Zonen für die Zenerdiode von der Rückseite des Halbleiterkörpers aus in diesen eingebracht. Es schließt sich eine Ausheilung der Anordnung an. Nach Metallisierung der Vorderseite des Halbleiterkörpers wird der NPT-IGBT in üblicher Weise fertig gestellt.A manufacturing method for the IGBT arrangement according to the invention provides for the embodiment mentioned at the penultimate point that first the NPT-IGBT is produced until its metallization in a conventional manner. Then, the two n + be by masked ion implantation - or p + -type zones for the Zener diode from the back side of the semiconductor body from introduced into this. This is followed by an annealing of the arrangement. After metallization of the front side of the semiconductor body of the NPT-IGBT is completed in the usual way.
Die erfindungsgemäße IGBT-Anordnung kann in beliebiger Chipgröße, also auch für höhere Spannungen und Stromwerte, hergestellt werden. Es ist so möglich, IGBT-Module mit relativ wenigen Halbleiterkörpern bzw. Halbleiterchips aufzubauen.The IGBT arrangement according to the invention can in any chip size, so also for higher voltages and current values are produced. It is so possible to use IGBT modules with relative few semiconductor bodies or build semiconductor chips.
