Description
Die Erfindung betrifft ein Halbleiterbauelement mit einem Halbleiterchip und einem Chipträger, wobei der Halbleiterchip auf seiner dem Chipträger zugewandten Vorderseite einen ersten und einen zweiten Anschlusskontakt aufweist und mit dem Chipträger verbunden ist. Diese Art der Anordnung wird auch als ”Flipchip-Anordnung” bezeichnet. Auf seiner der Vorderseite gegenüber liegenden Rückseite weist ein derartiger Halbleiterchip, der bevorzugt als Leistungshalbleiterchip ausgebildet ist, üblicherweise einen dritten Anschlusskontakt auf.The invention relates to a semiconductor component having a semiconductor chip and a chip carrier, wherein the semiconductor chip has on its front side facing the chip carrier a first and a second connection contact and is connected to the chip carrier. This type of arrangement is also referred to as a "flip-chip arrangement". On its rear side opposite the front side, such a semiconductor chip, which is preferably designed as a power semiconductor chip, usually has a third connection contact.
Bei dem ersten bzw. dritten Anschlusskontakt handelt es sich beispielsweise um einen ersten und einen zweiten Lastanschluss eines in den Halbleiterchip integrierten Bauelements, beispielsweise um den Source-Anschluss bzw. den Drain-Anschluss eines n-Kanal MOSFETs oder IGBTs. Der zweite Anschlusskontakt bildet einen Steueranschluss des Bauelements, d. h. ein Gate-Anschlussbein eines in den Chip integrierten MOSFETs.By way of example, the first and third connection contacts are a first and a second load connection of a component integrated in the semiconductor chip, for example the source connection or the drain connection of an n-channel MOSFET or IGBT. The second terminal contact forms a control terminal of the device, i. H. a gate terminal of a chip-integrated MOSFET.
Die Flipchip-Anordnung wird beispielsweise gewählt, um anstelle des an der Rückseite angeordneten, bei vielen Anwendungen auf hohem elektrischen Potential liegenden dritten Anschlusskontaktes den an der Vorderseite angeordneten ersten Anschlusskontakt, der üblicherweise auf einem niedrigeren elektrischen Potential liegt, mit dem Chipträger elektrisch und mechanisch zu verbinden. Durch diese Maßnahme werden Schaltungsverluste sowie elektromagnetische Störstrahlungen reduziert, die anderenfalls, nämlich beim Anschließen des Chipträgers an das hohe Potential des dritten Anschlusskontaktes, aus der verhältnismäßig hohen Kapazität sowie den großen Abmessungen des Chipträgers resultieren.The flip-chip arrangement is chosen, for example, to electrically and mechanically connect the chip carrier with the chip carrier instead of the rear terminal, which is located at the high electrical potential in many applications, in the third terminal contact, which is arranged on the front side connect. By this measure, circuit losses and electromagnetic interference radiation are reduced, which otherwise, namely when connecting the chip carrier to the high potential of the third terminal contact, resulting from the relatively high capacity and the large dimensions of the chip carrier.
Bei derartigen Anordnungen liegt der auf der Rückseite des Halbleiterchips angeordnete dritte Anschlusskontakt auf einem hohen elektrischen Potential gegenüber dem Chipträger. Dieses hohe elektrische Potential erstreckt sich infolge einer beim Sägen des Halbleiterchips auftretenden Oberflächenveränderung an dessen in vertikaler Richtung verlaufenden Seiten bis an die dem Chipträger zugewandten Kanten des Halbleiterchips.In such arrangements, the third connection contact arranged on the rear side of the semiconductor chip is at a high electrical potential with respect to the chip carrier. This high electrical potential extends as a result of occurring during sawing of the semiconductor chip surface change at its vertically extending sides to the chip carrier facing edges of the semiconductor chip.
Um eine ausreichende Spannungsfestigkeit des Halbleiterbauelements zu erreichen ist es erforderlich, einen ausreichend großen Abstand zwischen der Vorderseite des Halbleiterchips und dem Chipträger vorzusehen. Andererseits ist es vorteilhaft, diesen Abstand nicht zu groß zu wählen, da sich hierdurch insbesondere die Wärmeableitung vom Halbleiterchip über zur Kontaktierung verwendete Lotkugel zum Chipträger unnötig verschlechtert.In order to achieve a sufficient dielectric strength of the semiconductor device, it is necessary to provide a sufficiently large distance between the front side of the semiconductor chip and the chip carrier. On the other hand, it is advantageous not to choose this distance too large, since in particular the heat dissipation from the semiconductor chip via solder ball used for contacting unnecessarily deteriorates to the chip carrier.
Üblicherweise wird eine Flipchip-Anordnung mittels an den Anschlusskontakten angeordneten Lotkugeln die auch als ”Solder Balls” bezeichnet werden, aus einem niedrigschmelzenden Metall bzw. einer niedrigschmelzenden Legierung realisiert. Bei der Montage wird der Halbleiterchip mit den Lotkugeln auf den aufgeheizten Chipträger gesetzt, wobei die Lotkugeln schmelzen und so den Halbleiterchip mit dem Chipträger elektrisch und mechanisch verbinden. Diese Anordnung weist jedoch den Nachteil auf, dass es schwierig ist, mit derartigen Lotkugeln einen definierten Abstand einzustellen.Usually, a flip-chip arrangement is realized by means of solder balls, which are also referred to as "solder balls", arranged on the connection contacts, from a low-melting metal or a low-melting alloy. During assembly, the semiconductor chip is placed with the solder balls on the heated chip carrier, wherein the solder balls melt and so electrically and mechanically connect the semiconductor chip with the chip carrier. However, this arrangement has the disadvantage that it is difficult to set a defined distance with such solder balls.
Bei derartigen Halbleiterchips mit Flipchip-Anordnung müssen insbesondere der erste und der zweite Anschlusskontakt jeweils mit einem elektrisch leitenden Anschluss kontaktiert werden. Da diese beiden Anschlusskontakte auf derselben Seite des Halbleiterchips angeordnet sind, dürfen die entsprechenden elektrischen Anschlüsse nicht elektrisch leitend miteinander verbunden sein, was die Verwendung eines vollmetallischen Chipträgers erschwert. Alternativ zu einem vollmetallischen Chipträger werden auch Chipträger mit einem elektrisch isolierenden Träger verwendet, die mit einer strukturierten Metallisierung versehen sind und die außerdem noch eine gute Wärmeleitfähigkeit aufweisen. Derartige Chipträger, beispielsweise mit Kupfer beschichtete Keramikträger, sogenannte DCB-Substrate (DCB = Direct Copper Bonding), weisen den Nachteil auf, dass sie teuer in der Herstellung sind.In such semiconductor chips with flip-chip arrangement, in particular the first and the second terminal contact must be contacted in each case with an electrically conductive terminal. Since these two connection contacts are arranged on the same side of the semiconductor chip, the corresponding electrical connections must not be connected to one another in an electrically conductive manner, which makes the use of a fully metallic chip carrier more difficult. As an alternative to a fully metallic chip carrier chip carriers are also used with an electrically insulating support, which are provided with a structured metallization and also also have a good thermal conductivity. Such chip carriers, for example copper-coated ceramic carriers, so-called DCB substrates (DCB = Direct Copper Bonding), have the disadvantage that they are expensive to manufacture.

Es ist die Aufgabe der vorliegenden Erfindung, ein Halbleiterbauelement mit einem Halbleiterchip bereitzustellen, das elektrisch mit einem preiswerten Chipträger kontaktiert ist, und bei dem ein einzuhaltender Mindestabstand zwischen dem Halbleiterchip und dem Chipträger auf einfache Weise eingestellt ist, sowie ein Verfahren zur Herstellung eines solchen Halbleiterbauelements.It is the object of the present invention to provide a semiconductor device with a semiconductor chip which is electrically contacted with a low-cost chip carrier, and in which a minimum distance to be observed between the semiconductor chip and the chip carrier is set in a simple manner, and a method for producing such a semiconductor device ,
Diese Aufgabe wird durch ein Halbleiterbauelement gemäß den Merkmalen des Anspruchs 1 bzw. durch ein Verfahren zur Herstellung eines Halbleiterbauelements gemäß Anspruch 14 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a semiconductor component according to the features of
Das Halbleiterbauelement umfasst einen Halbleiterchip und einen Chipträger, wobei der Halbleiterchip eine erste Seite aufweist, die dem Chipträger zugewandt ist und an der ein erster Anschlusskontakt und ein zweiter Anschlusskontakt angeordnet sind. Der Chipträger umfasst des weiteren einen ersten Chipträgerteil und einen von diesem beabstandeten und getrennten zweiten Chipträgerteil. Eine erste Kontaktschicht ist zwischen dem ersten Anschlusskontakt und dem ersten Chipträgerteil angeordnet und verbindet diese elektrisch leitend miteinander. Entsprechend ist eine zweite Kontaktschicht zwischen dem zweiten Anschlusskontakt und dem zweiten Chipträgerteil angeordnet und verbindet diese ebenfalls elektrisch leitend miteinander.The semiconductor device comprises a semiconductor chip and a chip carrier, wherein the semiconductor chip has a first side, which faces the chip carrier and on which a first connection contact and a second connection contact are arranged. The chip carrier further comprises a first chip carrier part and a second chip carrier part spaced from and separated from the chip carrier part. A first contact layer is arranged between the first connection contact and the first chip carrier part and connects them to one another in an electrically conductive manner. Accordingly, a second contact layer between the second terminal contact and the second chip carrier member is arranged and connects these also electrically conductive with each other.
Die Dicken der ersten und zweiten Kontaktschicht in einer vertikalen Richtung des Halbleiterchips sind so gewählt, dass zwischen der Vorderseite des Halbleiterchips und dem Chipträger ein vorgegebener minimaler Abstand nicht unterschritten ist. Dieser minimale Abstand ist dabei unter Berücksichtigung einer gewünschten Spannungsfestigkeit des Bauelementes gewählt und insbesondere so gewählt, dass eine vorgegebene Mindestspannungsfestigkeit erreicht wird.The thicknesses of the first and second contact layers in a vertical direction of the semiconductor chip are selected so that a predetermined minimum distance is not undershot between the front side of the semiconductor chip and the chip carrier. This minimum distance is chosen taking into account a desired dielectric strength of the component and in particular chosen so that a predetermined minimum voltage resistance is achieved.
Die erste bzw. zweite Kontaktschicht dienen als Abstandhalter zwischen dem Chipträger und dem Halbleiterchip. Da mit zunehmender Dicke der ersten bzw. zweiten Kontaktschicht der Wärmewiderstand zwischen Halbleiterchip und Chipträger steigt und da die Kosten sowie der Zeitbedarf für die Herstellung derartiger Kontaktschichten mit deren Schichtdicke ansteigen, ist die Dicke idealerweise so gewählt, dass die erforderliche Isolationsfestigkeit, ggf. unter Berücksichtigung einer bestimmten Sicherheitszuschlages, gerade erreicht ist.The first and second contact layers serve as spacers between the chip carrier and the semiconductor chip. Since the thermal resistance between the semiconductor chip and the chip carrier increases with increasing thickness of the first or second contact layer, and since the costs and the time required for the production of such contact layers increase with their layer thickness, the thickness is ideally chosen so that the required insulation resistance, possibly taking into account a certain security surcharge, has just been reached.
Bei der Herstellung eines erfindungsgemäßen Halbleiterbauelements wird die erste bzw. zweite Kontaktschicht vorzugsweise auf den ersten bzw. zweiten Anschlusskontakt des Halbleiterchips aufgebracht.In the production of a semiconductor component according to the invention, the first or second contact layer is preferably applied to the first or second terminal contact of the semiconductor chip.
Anschließend wird der Halbleiterchip mittels Lötverbindungen, die zwischen dem Chipträger und der ersten bzw. zweiten Kontaktschicht angeordnet sind, miteinander verbunden. Dabei ist es vorteilhaft, wenn der Schmelzpunkt der ersten und zweiten Kontaktschicht höher ist als der Schmelzpunkt des dabei verwendeten, externen Anschluss-Lotes von vorzugsweise 180°C–230°C. Dadurch ist es möglich, das Halbleiterbauteil mit dem Chipträger, beispielsweise einem PCB-Träger (PCB = Printed Circuit Board), zu verlöten, ohne gleichzeitig die erste und zweite Kontaktschicht aufzuschmelzen. Der Schmelzpunkt der ersten bzw. zweiten Kontaktschicht liegt vorzugsweise über 260°C und damit über dem Schmelzpunkt typischer Lotkugeln von üblicherweise zwischen 180°C und 230°C.Subsequently, the semiconductor chip is connected to each other by means of solder joints, which are arranged between the chip carrier and the first and second contact layer. It is advantageous if the melting point of the first and second contact layer is higher than the melting point of the external connection solder used therein, preferably 180 ° C-230 ° C. This makes it possible to solder the semiconductor component to the chip carrier, for example a PCB carrier (PCB = printed circuit board), without simultaneously melting the first and second contact layers. The melting point of the first or second contact layer is preferably above 260 ° C and thus above the melting point of typical solder balls of usually between 180 ° C and 230 ° C.
Ebenso ist es möglich, die Kontaktschichten auf geeignete Stellen des Chipträgers aufzubringen und sie dann mit den betreffenden Anschlusskontakten des Halbleiterchips zu verlöten.It is likewise possible to apply the contact layers to suitable locations of the chip carrier and then to solder them to the respective connection contacts of the semiconductor chip.
Der Chipträger umfasst einen ersten und einen zweiten Chipträgerteil, die voneinander beabstandet sind. Der erste und zweite Chipträgerteil sind bei der Herstellung des Halbleiterbauelementes, insbesondere bei der Herstellung der oben genannten Lötverbindung zwischen den Kontaktschichten und dem Chipträger, fest miteinander verbunden und werden in einem späteren Verfahrensschritt voneinander getrennt. Dieses Verfahren erleichtert die Justierung zwischen dem Halbleiterchip und dem ersten bzw. zweiten Chipträgerteil. Des Weiteren ermöglicht sie die Verwendung eines vollmetallischen Chipträgers, da der erste und der zweite Chipträgerteil nach der Trennung nicht mehr elektrisch leitend miteinander verbunden sind.The chip carrier comprises a first and a second chip carrier part, which are spaced apart from each other. The first and second chip carrier parts are firmly connected to one another in the production of the semiconductor component, in particular during the production of the abovementioned solder connection between the contact layers and the chip carrier, and are separated from one another in a later method step. This method facilitates the adjustment between the semiconductor chip and the first and second chip carrier part. Furthermore, it allows the use of a fully metallic chip carrier, since the first and the second chip carrier part are no longer electrically connected to each other after the separation.
Zur Erhöhung der Isolationsfestigkeit ist es vorgesehen, zwischen den Halbleiterchip und den Chipträger ein Isolationsmaterial einzubringen. Das Isolationsmaterial wird bevorzugt in den zwischen den Halbleiterchip und dem Chipträger ausgebildeten Zwischenraum eingegossen oder eingespritzt. Besonders bevorzugt wird als Isolationsmaterial eine Vergussmasse verwendet, mit der zumindest der Halbleiterchip des Halbleiterbauelementes während eines nachfolgenden Verfahrensschrittes vergossen bzw. umspritzt wird.To increase the insulation resistance, it is provided to introduce an insulating material between the semiconductor chip and the chip carrier. The insulating material is preferably poured or injected into the intermediate space formed between the semiconductor chip and the chip carrier. Particularly preferably, a potting compound is used as insulation material, with which at least the semiconductor chip of the semiconductor component is potted or encapsulated during a subsequent method step.
Die typischerweise verwendeten Isolationsmaterialien bzw. Vergussmassen weisen eine Isolationsfestigkeit von vorzugsweise über 50 V/μm auf.The insulating materials or potting compounds typically used have an insulation resistance of preferably more than 50 V / μm.
Die Herstellung der ersten und/oder zweiten Kontaktschicht kann beispielsweise mittels physikalischer (PVD = Physical Vapour Deposition) oder chemischer (CVD = Chemical Vapour Deposition) Abscheidung aus der Gasphase, mittels galvanischer bzw. stromloser Abscheidung oder durch Sputtern erfolgen. Die Abscheidung erfolgt vorzugsweise auf einer mit Öffnungen versehenen Maskenschicht. Bevorzugte Materialien für die erste und zweite Kontaktschicht sind Kupfer, Aluminium und weitere Metalle wie z. B. Gold, Silber, Zinn, Titan, oder Nickel oder Legierungen mit zumindest einem dieser Metalle.The first and / or second contact layer can be produced, for example, by means of physical (PVD = Physical Vapor Deposition) or chemical (CVD = Chemical Vapor Deposition) deposition from the gas phase, by means of galvanic or currentless deposition or by sputtering. The deposition is preferably carried out on an apertured mask layer. Preferred materials for the first and second contact layers are copper, aluminum and other metals such. As gold, silver, tin, titanium, or nickel or alloys with at least one of these metals.
