Abstract
Description
Die Erfindung betrifft einen Schaltungsträger für elektronische Bauelemente gemäß dem Oberbegriff des Anspruchs 1 und ein Verfahren zu dessen Herstellung.The invention relates to a circuit carrier for electronic components according to the preamble of claim 1 and a method for its production.
Unter einem Schaltungsträger für elektronische Bauelemente wird hier eine Grundplatte (Substrat) verstanden, auf der elektronische Bauelemente, beispielsweise integrierte Schaltkreise, angeordnet sind oder angeordnet werden können. Der Begriff Schaltungsträger umfasst dabei insbesondere Wafer für sogenannte Wafer Level Packages und rekonfigurierte (künstliche) Wafer für sogenannte Embedded Wafer Level Packages.A circuit carrier for electronic components is here understood to mean a base plate (substrate) on which electronic components, for example integrated circuits, are arranged or can be arranged. In this case, the term circuit carrier includes in particular wafers for so-called wafer level packages and reconfigured (artificial) wafers for so-called embedded wafer level packages.
Derartige Schaltungsträger werden häufig auf einer Kontaktierungsseite mit Lothügeln zur elektrischen Kontaktierung der elektronischen Bauelemente versehen, wobei die Lothügel beispielsweise als Kugelgitter (Ball Grid Array) angeordnet werden.Such circuit carriers are often provided on a contacting side with solder bumps for making electrical contact with the electronic components, wherein the solder bumps are arranged, for example, as a ball grid (ball grid array).
Die
Der Erfindung liegt die Aufgabe zugrunde, einen verbesserten Schaltungsträger für elektronische Bauelemente anzugeben, der Lothügel zur Kontaktierung der elektronischen Bauelemente aufweist. Ferner liegt der Erfindung die Aufgabe zugrunde, ein verbessertes Verfahren zur Herstellung eines derartigen Schaltungsträgers anzugeben.The invention has for its object to provide an improved circuit carrier for electronic components, the solder bump has for contacting the electronic components. Furthermore, the invention has for its object to provide an improved method for producing such a circuit substrate.
Die Aufgabe wird erfindungsgemäß hinsichtlich des Schaltungsträgers durch die in Anspruch 1 angegebenen Merkmale und hinsichtlich des Verfahrens durch die in Anspruch 7 angegebenen Merkmale gelöst.The object is achieved in terms of the circuit substrate by the features specified in claim 1 and in terms of the method by the features specified in claim 7.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Ein erfindungsgemäßer Schaltungstrger für elektronische Bauelemente weist eine Kontaktierungsoberfläche auf, auf der Lothügel zur elektrischen Kontaktierung elektronischer Bauelemente angeordnet sind. Jeder Lothügel ist in eine auf die Kontaktierungsoberfläche aufgebrachte Kunststofffassung derart eingebettet, dass ein Oberflächenbereich des Lothügels freiliegt. Dabei bilden die Kunststofffassungen eine zusammenhängende Kunststoffschicht.An inventive circuit substrate for electronic components has a contacting surface, are arranged on the solder bumps for electrical contacting electronic components. Each solder bump is embedded in a plastic socket applied to the contacting surface such that a surface area of the solder broom is exposed. The plastic fittings form a coherent plastic layer.
Die Kunststoffschicht stützt die Lothügel und erhöht dadurch vorteilhaft die Zuverlässigkeit des Schaltungsträgers, verglichen mit Schaltungsträgern mit nicht gestützten Lothügeln. Schaltungsträger mit durch Kunststofffassungen gestützten Lothügeln sind bereits aus der
Vorzugsweise ist ein erfindungsgemäßer Schaltungstrager ein mit den Lothügeln und der Kunststoffschicht versehener Wafer für Wafer Level Packages oder rekonfigurierter Wafer für Embedded Wafer Level Packages. Derartige Schaltungsträger ermöglichen vorteilhaft die Einbringung in besonders kompakte und platzsparende Gehäuse (Packages).Preferably, a circuit carrier according to the invention is a wafer provided with the solder bumps and the plastic layer for wafer level packages or reconfigured wafers for embedded wafer level packages. Such circuit carriers advantageously allow the introduction into particularly compact and space-saving housings (packages).
Die die Lothügel stützende Kunststoffschicht ist vorzugsweise eine Epoxidharzschicht. Die Verwendung von Epoxidharz ermöglicht vorteilhaft eine hohe Festigkeit und chemische Beständigkeit der Kunststoffschicht.The plastic layer supporting the solder bumps is preferably an epoxy resin layer. The use of epoxy resin advantageously allows high strength and chemical resistance of the plastic layer.
Die freiliegenden Oberflächenbereiche der Lothügel sind vorzugsweise planar und, besonders bevorzugt, zueinander planparallel ausgebildet.The exposed surface areas of the solder bumps are preferably planar and, particularly preferably, plane-parallel to one another.
Derartige freiliegende Oberflächenbereiche können mit dem unten beschriebenen erfindungsgemäßen Verfahren leicht hergestellt werden, indem zunächst Lotpastenhügel auf die Kontaktierungsoberfläche aufgebracht und diese mit Kunststoff beschichtet werden, und anschließend obere Bereiche der Lotpastenhügel abgetragen werden. Dadurch können die Lothügel in einfacher Weise aus Lotpaste hergestellt werden, statt aus hochwertigen und teuren vorgeformten Lotkugeln mit einer geringen Streuung von Durchmesser und Lothügelhöhe, wie bei dem aus der
Ferner erhöht die Planarität der freiliegenden Oberflächenbereiche die Kontaktierungssicherheit der Lothügel, insbesondere wenn diese länglich ausgebildet sind, und damit die Zuverlässigkeit des Schaltungsträgers.Furthermore, the planarity of the exposed surface areas increases the contact security of the solder bumps, especially if they are elongated, and thus the reliability of the circuit substrate.
Weiterhin weisen vorzugsweise alle Lothügel eine gleiche Höhe auf und eine maximale Dicke der Kunststoffschicht ist kleiner als diese Höhe der Lothügel. Dabei wird unter der Höhe eines Lothügels das Maximum der Abstände der Punkte auf seiner Oberfläche von der Kontaktierungsoberfläche des Schaltungsträgers verstanden. Die gleiche Höhe der Lothügel ermöglicht es, alle Lothügel in gleicher Weise zu kontaktieren und erleichtert so vorteilhaft die Kontaktierung des Schaltungsträgers. Dass diese Höhe größer als die maximale Dicke der Kunststoffschicht ist, verhindert ein Überstehen der Kunststoffschicht über die Lothügel und verbessert weiter die Kontaktierbarkeit des Schaltungsträgers, beispielsweise mittels einer planen Leiterplatte, die auf die freiliegende Oberflächenbereiche der Lothügel platziert wird.Furthermore, preferably all the solder bumps have the same height and a maximum thickness of the plastic layer is smaller than this height of the solder bumps. In this case, the maximum of the distances of the points on its surface from the contacting surface of the circuit carrier is understood as the height of a solder bump. The same height of the solder bump makes it possible to contact all the solder bumps in the same way and thus facilitates the contact of the circuit carrier advantageous. The fact that this height is greater than the maximum thickness of the plastic layer prevents the plastic layer from overhanging the solder bumps and further improves the contactability of the circuit carrier, for example by means of a planar printed circuit board placed on the exposed surface areas of the solder bumps.
Bei dem erfindungsgemäßen Verfahren zur Herstellung eines erfindungsgemäßen Schaltungsträgers wird dessen Kontaktierungsoberfläche folgendermaßen mit den Lothügeln und der Kunststoffschicht versehen. Zunächst werden in einem ersten Verfahrensschritt die Lothügel auf die Kontaktierungsoberfläche aufgebracht. Danach werden in einem zweiten Verfahrensschritt die freiliegenden Bereiche der Lothügeloberflächen und der Kontaktierungsoberfläche vollständig mit Kunststoff beschichtet. Schließlich wird nach der Aushärtung des Kunststoffes in einem dritten Verfahrensschritt von jedem Lothügel ein kunststoffbeschichteter Bereich abgetragen.In the method according to the invention for producing a circuit carrier according to the invention whose contacting surface is provided as follows with the solder bumps and the plastic layer. First, in a first process step, the solder bumps are applied to the contacting surface. Thereafter, in a second process step, the exposed areas of the Lothügeloberflächen and the contacting surface are completely coated with plastic. Finally, after curing of the plastic in a third process step, a plastic-coated area is removed from each solder bump.
Der entscheidende Vorteil des Verfahrens gegenüber aus dem Stand der Technik, beispielsweise aus der
In einer bevorzugten Ausgestaltung des Verfahrens wird der Kunststoff im zweiten Verfahrensschritt mittels eines Rotationsbeschichtungsverfahrens (eines sogenannten Spin-Coating-Verfahrens) aufgetragen. Dadurch kann die gesamte Kunststoffschicht in einem Arbeitsschritt erzeugt werden und es kann auf bekannte und bewährte Techniken zurückgegriffen werden.In a preferred embodiment of the method, the plastic is applied in the second method step by means of a spin coating method (a so-called spin coating method). Thereby, the entire plastic layer can be produced in one step and it can be used on known and proven techniques.
Ferner wird im zweiten Verfahrensschritt aus oben bereits genannten Gründen als Kunststoffvorzugsweise Epoxidharz verwendet und eine Kunststoffschicht aufgetragen, deren maximale Dicke kleiner als die Höhe jedes Lothügels ist.Further, in the second process step, for reasons already mentioned above, epoxy resin is preferably used and a plastic layer is applied, the maximum thickness of which is less than the height of each solder bump.
Die im dritten Verfahrensschritt abgetragenen Bereiche der Lothügel werden vorzugsweise durch Läppen, Schleifen, Fräsen, Hobeln oder mechanisches und/oder chemisches Polieren abgetragen. Dadurch können alle Lothügel vorteilhaft in einem Arbeitsschritt bearbeitet werden. Insbesondere können in diesem Arbeitsschritt in einfacher Weise plane und zueinander planparallele Oberflächenbereiche der Lothügel mit oben bereits genannten Vorteilen freigelegt werden. Das Abtragen kunststoffbeschichteter Bereiche der Lothügel ist nicht nur einfach sondern auch zuverlässig und praktisch unabhängig von dem verwendeten Kunststoff sowie der Art von verwendeten Kunststofffillstoffen oder Kunststoffhaftvermittlern.The removed in the third process step areas of the solder bumps are preferably removed by lapping, grinding, milling, planing or mechanical and / or chemical polishing. As a result, all solder bumps can be advantageously processed in one step. In particular, planar and mutually plane-parallel surface areas of the solder bumps with above-mentioned advantages can be exposed in a simple manner in this step. The removal of plastic-coated areas of the solder bumps is not only simple but also reliable and practically independent of the plastic used as well as the type of plastic or plastic bonding agents used.
Weitere Merkmale und Einzelheiten der Erfindung werden im Folgenden anhand von Ausführungsbeispielen unter Bezugnahme auf Zeichnungen beschrieben.Further features and details of the invention will be described below with reference to embodiments with reference to drawings.
