Description
Die Erfindung bezieht sich auf ein Verfahren zum Herstellen elektronischer Halbleiterbauelemente zur Oberflächenmontage.The The invention relates to a method for manufacturing electronic Semiconductor devices for surface mounting.
Ein
solches Herstellverfahren nach dem Stand der Technik ist beispielsweise
aus der deutschen Offenlegungsschrift
Dieses Herstellverfahren weist jedoch den Nachteil auf, dass die damit hergestellten lichtemittierenden Bauelemente vergleichsweise große Abmessungen aufweisen, dass eine strukturierte Leiterplatte gebraucht wird und Kontaktierungen von der Unterseite der Leiterplatte aufwendig auf ihre Oberseite geführt werden müssen.This However, manufacturing method has the disadvantage that the so produced light-emitting components comparatively large dimensions have that a structured circuit board is needed and Contacting the bottom of the circuit board consuming on led her top Need to become.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Herstellen elektronischer Halbleiterbauelemente zur Oberflächenmontage so zu gestalten, dass elektronische Halbleiterbauelemente mit sehr kleinen Abmessungen kostengünstig und auf einfache Art und Weise massenweise hergestellt werden können.Of the Invention is based on the object, a method for manufacturing to design electronic surface mount semiconductor devices that electronic semiconductor devices with very small dimensions economical and can be mass produced in a simple way.
Gelöst wird diese Aufgabe durch ein Verfahren mit den im Anspruch 1 angegebenen Merkmalen.Is solved this object by a method with the specified in claim 1 Features.
Nach dem Verfahren des Anspruchs 1 hergestellte elektronische Halbleiterbauelemente weisen die Vorteile auf, dass sie einfach und kostengünstig herzustellen sind und die Kontaktflächen des Bauelements nicht mit dem Material der Verkapselung verunreinigt sind.

Das am Beispiel vom lichtaussendenden Halbleiterbauelementen (Micro-SMD-Leuchtdiode) in zwei Versionen beschriebene Verfahren eignet sich auch für die Herstellung anderer oberflächenmontierter elektronischer Halbleiterbauelemente mit sehr kleinen Abmessungen, wie mehrfarbige Leuchtdioden, Dioden, Transistoren und integrierte Schaltkreise. Hierfür ist in vielen Fällen die Verwendung lichtundurchlässiger Vergussmasse sinnvoll. Benötigt ein Halbleiterbauelement mehr als zwei elektrische Anschlüsse, wie dies bei mehrfarbigen Leuchtdioden, Transistoren und vor allem bei integrierten Schaltkreisen der Fall ist, muss die Strukturierung des Substrats (Trägerplatte oder Trägerband) entsprechend angepasst werden, was jedoch für einen einschlägigen Fachmann kein Problem darstellt. Die anfangs genannten Vorteile des erfindungsgemäßen Herstellverfahrens bleiben auch bei derartigen Modifikationen voll erhalten.The using the example of light-emitting semiconductor devices (micro SMD LED) in two Versions described method is also suitable for the production other surface mount electronic semiconductor devices with very small dimensions, like multicolored light emitting diodes, diodes, transistors and integrated Circuits. Therefor is in many cases the use of opaque Sealing compound makes sense. requires a semiconductor device more than two electrical connections, like this in multicolor light emitting diodes, transistors and especially in integrated Circuitry is the case, the structuring of the substrate needs (Support plate or carrier tape) be adjusted accordingly, but for a relevant expert no problem. The initially mentioned advantages of the production process according to the invention remain fully preserved even with such modifications.
