Description
Die Erfindung betrifft eine Multichip-Anordnung mit mehreren aufeinandergestapelten Chips.The The invention relates to a multi-chip arrangement with a plurality of stacked Crisps.
Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung einer solchen Multichip-Anordnung.The Invention further relates to a method for producing a such a multi-chip arrangement.
Wenn mehrere Chips in einer Multichip-Anordnung aufeinandergestapelt werden, um beispielsweise ein System in einem Gehäuse (SiP System in Package) zu bilden, nimmt die Leistungsaufnahme mit der erhöhten Anzahl von Chips in dem Gehäuse zu, und es wird Wärme erzeugt, die abgeführt werden muss, um eine Überhitzung des Chips zu vermeiden. Deshalb sind für künftige Multichip-Anordnungen zusätzlich Maßnahmen für eine verbesserte Wärmeableitung notwendig. Das Aufbringen von Kühlelementen auf das Gehäuse ist jedoch nicht ausreichend, die Wärme in ausreichender Geschwindigkeit aus dem Inneren des Gehäuses, d.h. aus dem Inneren des Chipstapels abzuführen.If several chips stacked in a multi-chip arrangement For example, to build a system in a housing (SiP System in Package) decreases the power consumption with the increased Number of chips in the housing too, and it will be heat generated, which dissipated must be to overheat to avoid the chip. That's why for future multichip arrangements additionally activities for one improved heat dissipation necessary. The application of cooling elements on the case but is not enough, the heat in sufficient speed from inside the case, i.e. remove from the interior of the chip stack.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Multichip-Anordnung zur Verfügung zu stellen, bei der die innerhalb der Multichip-Anordnung erzeugte Wärme in verbesserter Weise abgeführt werden kann. Es ist weiterhin eine Aufgabe der vorliegenden Erfindung, ein Verfahren zur Herstellung einer Multichip-Anordnung zur Verfügung zu stellen, wobei die Multichip-Anordnung eine verbesserte Wärmeableitung aufweist.It is therefore an object of the present invention, a multi-chip arrangement to disposal in which the generated within the multi-chip arrangement Heat in improved manner dissipated can be. It is further an object of the present invention to provide a method for producing a multi-chip arrangement, wherein the multi-chip arrangement has improved heat dissipation.
Diese Aufgabe wird durch die Multichip-Anordnung gemäß Anspruch 1 sowie durch das Verfahren nach Anspruch 12 gelöst.These The object is achieved by the multi-chip arrangement according to claim 1 and by the A method according to claim 12 solved.
Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.advantageous Embodiments of the invention are specified in the dependent claims.
Gemäß einem ersten Aspekt der vorliegenden Erfindung ist eine Multichip-Anordnung vorgesehen mit einem Substrat mit einer ersten Oberfläche, auf der mehrere Kontaktelemente angeordnet sind. Auf einer zweiten Oberfläche des Substrats sind mehrere Chips in einer Stapelanordnung aufeinander angeordnet, die jeweils über eine Verbindungseinrichtung untereinander und/oder mit den Kontaktelementen elektrisch verbunden sind. Mit Hilfe einer Wärmeleiteinrichtung kann im Inneren der Multichip-Anordnung erzeugte Wärme in Richtung einer von der Seite des Substrats verschiedenen, insbesondere gegenüberliegenden Seite der Stapelanordnung abgeleitet werden.According to one The first aspect of the present invention is a multi-chip arrangement provided with a substrate having a first surface, on the plurality of contact elements are arranged. On a second surface of the Substrate, several chips are arranged in a stacked arrangement, each over a connecting device with each other and / or with the contact elements are electrically connected. With the help of a heat conduction can in Heat generated in the interior of the multi-chip arrangement in the direction of one of the Side of the substrate different, in particular opposite Side of the stack assembly are derived.
Durch die zusätzliche vorgesehene Wärmeleiteinrichtung ist es möglich, die innerhalb der Stapelanordnung erzeugte Wärme so abzuleiten, dass eine zusätzliche Wärmeabfuhr an einer Seite der Multichip-Anordnung möglich ist, an der die Wärme besser abgeführt werden kann als auf der Seite des Substrats, das mit den Kontaktelementen versehen ist.By the extra provided heat conducting device Is it possible, derive the heat generated within the stack assembly so that a additional heat dissipation on one side of the multi-chip arrangement is possible, where the heat better dissipated can be considered as on the side of the substrate that is connected to the contact elements is provided.
Gemäß einer bevorzugten Ausführungsform der Erfindung weisen die mehreren Chips jeweils einen aktiven Bereich auf einer aktiven Oberfläche auf, wobei die aktiven Oberflächen von einem oder mehreren von ersten Chips in der Stapelanordnung zu einer der ersten gegenüberliegenden zweiten Oberfläche des Substrats gleichgerichtet sind und wobei als Wärmeleiteinrichtung auf einer dem Substrat gegenüberliegenden Seite der Stapelanordnung ein zweiter Chip vorgesehen ist, dessen aktive Oberfläche zur zweiten Oberfläche des Substrats entgegengesetzt gerichtet ist. Auf diese Weise ist es möglich, dass die dem Substrat gegenüberliegende Seite der Stapelanordnung durch eine Rückseite des zweiten Chips gebildet wird, auf die in einfacher Weise ein Kühlelement aufgebracht werden kann. Dies wäre nur erschwert möglich, wenn diese Seite durch eine aktive Oberfläche des obersten Chips der Stapelanordnung gebildet würde, da sich darauf aufgrund der unebenen Flächenstruktur (z. B. Bonddrähte) ein Kühlelement mit einer ausreichenden Wärmeableitung nicht aufbringen lässt und/oder eine Wärmeleitpaste für die dort befindlichen integrierten Schaltkreise zu aggressiv wäre.According to one preferred embodiment of Invention, the plurality of chips each have an active area on an active surface on, with the active surfaces of one or more of first chips in the stacking arrangement to one of the first opposite second surface of the substrate are rectified and being used as a heat conducting device on a substrate opposite Side of the stack arrangement, a second chip is provided, whose active surface to the second surface of the substrate is directed opposite. That way is it is possible that the opposite of the substrate Side of the stack assembly formed by a back of the second chip is, to which a cooling element can be applied in a simple manner can. This would be only difficult possible, if this page is due to an active surface of the top chip of the Stack arrangement would be formed, due to the uneven surface structure (eg bonding wires) cooling element with a sufficient heat dissipation can not raise and / or a thermal paste for the located there would be too aggressive integrated circuits.
Vorzugsweise ist der zweite Chip als Flip-Chip ausgebildet. Insbesondere kann der zweite Chip Kontaktstrukturen aufweisen, die eine elektrische und wärmeleitende Verbindung zu einem der ersten Chips bereit stellt.Preferably the second chip is designed as a flip-chip. In particular, can the second chip have contact structures that have an electrical and thermally conductive Provides connection to one of the first chips.
