Die Erfindung betrifft ein Verfahren zur Fixierung eines Bauelements oder eines Verbindungsmittels für eine Schaltungsanordnung auf einer Kontaktfläche. Die Erfindung betrifft ferner ein Bauelement mit einer Kontaktfläche zur Fixierung eines Verbindungsmittels sowie ein Substrat mit einer Kontaktfläche zur Fixierung eines Bauelements oder eines Verbindungsmittels. Die Erfindung betrifft auch Schaltungsanordnungen, bei denen ein Bauelement oder ein Verbindungsmittel auf einer Kontaktfläche fixiert sind.The The invention relates to a method for fixing a component or a bonding agent for a circuit arrangement on a contact surface. The invention relates Further, a component having a contact surface for fixing a connecting means and a substrate having a contact surface for fixing a component or a bonding agent. The invention also relates to circuit arrangements, in which a component or a connecting means are fixed on a contact surface.
Zur Verbindung eines Chips und eines Verdrahtungsträgers kann Bonden verwendet werden. Beim Bonden werden Kontaktflächen des Chips und des Verdrahtungsträgers mit Hilfe eines dünnen Drahtes verbunden. Der Draht wird beispielsweise mit einer Kapillare auf einer Kontaktfläche auf dem Verdrahtungsträger positioniert, dort fixiert, von der Kapillare zu einer Kontaktfläche des Chips geführt und dort fixiert.to Bonding of a chip and a wiring substrate may use bonding become. During bonding, contact surfaces of the chip and of the wiring substrate become visible Help of a thin wire connected. The wire, for example, with a capillary a contact surface on the wiring carrier positioned there, from the capillary to a contact surface of the Led and chips fixed there.
Das Fixieren kann mittels eines des Schweißens ähnlichen Verfahrens erfolgen, bei dem die zur Fixierung erforderliche Energie durch Ultraschall und/oder Wärme auf den auf der Kontaktfläche positionierten Draht aufgebracht wird.The Fixing can be done by means of a welding-like process, in which the energy required for fixing by ultrasound and / or Heat up on the contact surface positioned wire is applied.
Thermokompressionsbonden, Thermosonic-Ball-Wedge-Bonden und Ultraschall-Wedge-Wedge-Bonden sind Bondverfahren, die auf oben genanntem Prinzip beruhen.Thermo-compression bonding, Thermosonic ball wedge bonding and ultrasonic wedge-wedge bonding are bonding methods based on the above principle.
Bei wärmebasierten Fixierverfahren wird nicht nur die eigentliche Kontaktstelle erwärmt, sondern auch das benachbarte Bauelement oder Substrat in Mitleidenschaft gezogen.at heat-based Fixing not only the actual contact point is heated, but also affects the adjacent component or substrate drawn.
Beim Bonden unter Verwendung von Ultraschall ist ein relativ hoher Krafteintrag erforderlich. Auf die Chipoberfläche kann ein Krafteintrag im Bereich von 20 bis 100 cN einwirken. Bei nicht optimalem Bondprozess, beispielsweise im Fall einer Dejustierung der Kapillare, mit welcher der Bonddraht aufgebracht wird, können diese Kräfte auch eine Größenordnung größer ausfallen. Dadurch besteht die Gefahr, dass empfindliche Halbleiterschichten innerhalb des Chips beschädigt oder zerstört werden. Diese Beschädigungen können insbesondere bei Kombination von hohem Anpressdruck und Ultraschall auftreten.At the Bonding using ultrasound is a relatively high force input required. On the chip surface A force input in the range of 20 to 100 cN can act. at not optimal bonding process, for example in case of misalignment the capillary, with which the bonding wire is applied, this can personnel also an order of magnitude bigger. There is a risk that sensitive semiconductor layers damaged inside the chip or destroyed become. These damages can especially when combining high contact pressure and ultrasound occur.
Derartige Beschädigungen können bisher nur vermieden werden, wenn die Kontaktflächen zum Bonden nicht über den empfindlichen Halbleiterschichten innerhalb des Chips angeordnet werden. Dies geht allerdings mit einem größeren Flächenbedarf des Chips einher.such damage can So far, only be avoided if the contact surfaces for bonding not on the sensitive semiconductor layers disposed within the chip become. However, this is accompanied by a larger area requirement of the chip.
Es stellt sich nunmehr die Aufgabe, das Verfahren zur Fixierung zu verbessern.It now sets the task, the method of fixation improve.
Zur Lösung ist ein Verfahren zur Fixierung eines Bauelements oder eines Verbindungsmittels für eine Schaltungsanordnung auf einer Kontaktfläche vorgesehen, wobei die Kontaktfläche reaktives Material umfasst.

Bei diesem Verfahren ist lediglich ein Krafteintrag erforderlich, der ausreichend ist, um das reaktive Material zu zünden. Dieser Krafteintrag ist geringer als bei konventionellen Verfahren zur Fixierung, sodass Zerstörungen aufgrund zu hohen Krafteintrags werden vermieden. Die kritische Seitwärtsbewegung durch einen Ultraschallprozess entfällt.at This procedure requires only one entry into force is sufficient to ignite the reactive material. This power entry is less than conventional fixation methods, so destructions due to excessive force input are avoided. The critical sideways movement eliminated by an ultrasonic process.
Ferner ist ein Bauelement mit einer Kontaktfläche, die reaktives Material umfasst, vorgesehen. Das reaktive Material ist durch Krafteintrag zündbar zur Fixierung, bewirkt durch mit der Zündung einhergehende Reaktionswärme, eines auf der Kontaktfläche positionierten Verbindungsmittels.Further is a device with a contact surface, the reactive material includes provided.

The fixation is due to the heat of reaction of a ignited by force entry reactive material formed on the contact surface.
Ferner ist eine mit dem Verfahren korrespondierende Schaltungsanordnung mit einem Substrat mit einer ersten Kontaktfläche und einem Bauelement mit einer zweiten Kontaktfläche, das auf dem Substrat montiert ist, vorgesehen. Ein Verbindungsmittel verbindet die zweite Kontaktfläche mit der ersten Kontaktfläche. Die Verbindung zwischen dem Verbindungsmittel und der ersten Kontaktfläche und/oder der zweiten Kontaktfläche ist infolge der Reaktionswärme eines durch Krafteintrag gezündeten reaktiven Materials an der ersten und der zweiten Kontaktfläche beziehungsweise an der einer der ersten und der zweiten Kontaktfläche ausgebildet.Further is a circuit arrangement corresponding to the method with a substrate having a first contact surface and a component with a second contact surface, which is mounted on the substrate, provided.
