Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum Herstellen elektronischer Halbleiterbauelemente zur Oberflächenmontage nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for producing electronic Semiconductor components for surface mounting according to the preamble of Claim 1.
Ein solches Herstellverfahren nach dem Stand der Technik ist beispielsweise aus der deutschen Offenlegungsschrift DE 195 44 980 A1 bekannt. Bei die sem Herstellverfahren werden lichtemittierende Bauelemente dadurch hergestellt, indem auf der Unterseite eines isolierenden Substrats elektri sche Anschlüsse ausgebildet, auf die Oberseite geführt und dort mittels ei nes leitenden Verbindungsmittels wie Lot mit der n-seitigen und p-seitigen Elektrode eines LED-Chips verbunden werden. LED-Chip und das leitende Verbindungsmittel auf dem isolierenden Substrat werden durch ein licht durchlässiges Harz abgedichtet.Such a manufacturing process according to the prior art is, for example known from German published patent application DE 195 44 980 A1. At the Sem manufacturing process thereby light-emitting components made by electri on the underside of an insulating substrate cal connections formed, led to the top and there by means of egg a conductive connection means such as solder with the n-sided and p-sided Electrode of an LED chip can be connected. LED chip and the conductive Connection means on the insulating substrate are light permeable resin sealed.

Die Fig. 1a bis 1d zeigen perspektivische Darstellungen zur Erläuterung ver schiedener Arbeitsschritte einer ersten Version des erfindungsgemäßen Herstellungsverfahrens, am Beispiel lichtaussendender Halbleiterbauele mente 10 (Micro-SMD-Leuchtdioden), die auf einem leitfähigen Substrat 1 aufgebaut werden. Figs. 1a to 1d are perspective views for explaining ver VARIOUS steps of a first version of the manufacturing method according to the invention, the example of light emitting elements Halbleiterbauele 10 (micro-SMD light-emitting diodes), which are constructed on a conductive substrate 1.
Fig. 1a zeigt ein leitfähiges Substrat 1 mit einer Oberseite als erster Oberflä chenseite 1.1, einer Unterseite als zweiter Oberflächenseite 1.2 und einer abgeschnittenen Ecke 1.3 als sogenannte Missgriffssicherung zum Schutz vor falscher Orientierung des Substrats 1. Als leitfähiges Substrat 1 dient beispielsweise eine rechteckige metallene Trägerplatte aus einer Kupferle gierung oder einem vergleichbaren Material. Auf der Oberseite 1.1 des Sub strats 1 sollen beispielsweise lichtaussendende Halbleiterkörper regelmäßig, beispielsweise matrixmäßig in Reihen und Spalten, angeordnet werden. Auf der Unterseite 1.2 werden zu einem späteren Zeitpunkt elektrische An schlussflächen (Anschlüsse, Elektroden) 5 der herzustellenden Halbleiter bauelemente strukturiert. Die Größe des Substrats 1 entspricht in etwa Scheckkartengröße, richtet sich aber nach Anzahl der Halbleiterbauelemen te 10, die darauf aufgebaut werden sollen, und nach den Abmessungen der verwendeten Fertigungseinrichtungen; die Dicke des Substrats 1 beträgt etwa 125 µm. Zum Transport und zur Fixierung in den Fertigungseinrichtun gen dienen Transportöffnungen 8. FIG. 1 a shows a conductive substrate 1 with an upper side as the first surface side 1.1 , a lower side as a second surface side 1.2 and a cut corner 1.3 as a so-called misuse protection to protect against incorrect orientation of the substrate 1 . For example, a rectangular metal carrier plate made of a copper alloy or a comparable material is used as the conductive substrate 1 . On the top 1.1 of the substrate 1 , for example, light-emitting semiconductor bodies are to be arranged regularly, for example in a matrix in rows and columns. On the underside 1.2 , electrical connection surfaces (connections, electrodes) 5 of the semiconductor components to be produced are structured at a later time. The size of the substrate 1 corresponds approximately to credit card size, but depends on the number of semiconductor devices 10 , which are to be built on it, and on the dimensions of the manufacturing equipment used; the thickness of the substrate 1 is approximately 125 μm. Transport openings 8 are used for transport and for fixing in the production facilities.
In einem ersten Schritt werden beispielsweise lichtaussendende Halbleiter körper 2 auf der ersten Oberflächenseite 1.1 des Substrats 1 befestigt. So mit dient das Substrat 1 unter anderem als Träger für die lichtaussenden den Halbleiterkörper oder Halbleiterchips 2, wie in Fig. 1b dargestellt. Jedes lichtaussendende Halbleiterchip 2 wird zum Befestigen auf dem Substrat 1 zweckmäßigerweise maschinell auf die Oberflächenseite 1.1 des Substrats 1 aufgesetzt. Gleichzeitig wird eine erste elektrische Verbindung vom Halblei terkörper 2 zur ersten Oberflächenseite 1.1 des Substrats 1 hergestellt, in dem der nach unten gerichtete Rückseitenkontakt des Halbleiterchips 2 mittels eines leitfähigen Klebstoffes 3.2 (Fig. 5b) wie Silberleitklebstoff an einem ersten Anschlusspunkt elektrisch leitend mit der Oberseite 1.1 ver bunden wird. Einen entsprechend angepassten Rückseitenkontakt voraus gesetzt, kann das Halbleiterchip 2 auch auf die Oberseite 1.1 aufgelötet, durch thermisches Chipbonden oder auf andere Art und Weise mit ihr kon taktiert werden.In a first step, for example, light-emitting semiconductor bodies 2 are attached to the first surface side 1.1 of the substrate 1 . The substrate 1 thus serves, inter alia, as a carrier for the light-emitting semiconductor bodies or semiconductor chips 2 , as shown in FIG. 1b. Each light-emitting semiconductor chip 2 is expediently placed mechanically on the surface side 1.1 of the substrate 1 for attachment to the substrate 1 . Simultaneously, a first electrical connection from the semiconducting terkörper 2 is made of the substrate 1 to the first surface side of 1.1, in which the downwardly directed rear side contact of the semiconductor chip 2 by means of a conductive adhesive 3.2 (Fig. 5b) as Silberleitklebstoff at a first connecting point electrically conductively connected to the top 1.1 is connected. Assuming a correspondingly adapted rear side contact, the semiconductor chip 2 can also be soldered onto the top side 1.1 , can be contacted with it by thermal chip bonding or in some other way.
Daraufhin wird eine zweite elektrische Verbindung von jedem Halbleiter körper 2 zur ersten Oberflächenseite 1.1 des Substrats 1 hergestellt, indem der zweite Kontakt jedes lichtaussendenden Halbleiterchips 2, der nach oben gerichtete Vorderseitenkontakt, mittels eines Bonddrahtes 3.1 aus Gold oder Aluminium in geringem Abstand zum ersten Anschlusspunkt an einem zweiten Anschlusspunkt ebenfalls mit der Oberseite 1.1 des Substrats 1 kontaktiert wird.Then, a second electrical connection is made from each semiconductor body 2 to the first surface side 1.1 of the substrate 1 by the second contact of each light-emitting semiconductor chip 2 , the upward-facing front side contact, using a bonding wire 3.1 made of gold or aluminum at a short distance from the first connection point a second connection point is also contacted with the top 1.1 of the substrate 1 .
Nach der Kontaktierung wird in einem weiteren Arbeitsschritt jeder der auf der Oberseite 1.1 des Substrats 1 befestigten Halbleiterkörper 2 mit einem Gehäusekörper 4 versehen. Dazu wird jeder auf der Oberfläche 1.1 befestig te Halbleiterchip 2 einschließlich seiner Kontaktierungen 3.1 und 3.2 auf bekannte Art und Weise mittels eines Mouldprozesses, durch Gießen, Spritz gießen oder eine sonstige gebräuchliche Herstellungsweise mit isolieren dem Material eingekapselt, wie aus Fig. 1c hervor geht. Bei dem isolieren den Material, der in Verbindung mit dem Mouldprozess auch als Mouldmasse bezeichnet wird, handelt es sich beispielsweise um einen thermoplastischen Kunststoff.After the contacting, each of the semiconductor bodies 2 fastened on the upper side 1.1 of the substrate 1 is provided with a housing body 4 in a further working step. For this purpose, each semiconductor chip 2 fastened to the surface 1.1 , including its contacts 3.1 and 3.2, is encapsulated in a known manner by means of a molding process, by casting, injection molding or another customary production method with isolating the material, as can be seen from FIG. 1c. The insulating material, which is also referred to in connection with the molding process as a molding compound, is, for example, a thermoplastic.
Eine erste Möglichkeit zum Herstellen der Gehäusekörper 4 besteht darin, dass beim Moulden einzelne Kavitäten eines Mouldwerkzeugs zum Einsatz kommen, so dass die Gehäusekörper 4 aller lichtaussendenden Halbleiter bauelemente 10 gleichzeitig hergestellt werden. Durch in das Moldwerk zeug eingearbeitete Kanäle zur Durchleitung der Mouldmasse, auch als Mouldgates bezeichnet, entstehen während des Mouldvorgangs Verbin dungsstege 6 zwischen den in einer Reihe oder Spalte angeordneten Gehäu sekörpern 4 der Halbleiterbauelemente 10.A first possibility for producing the housing body 4 is that individual cavities of a molding tool are used for molding, so that the housing body 4 of all light-emitting semiconductor components 10 are produced simultaneously. By incorporated into the mold tool channels for passing the molding compound, also referred to as mold gates, connecting webs 6 are formed during the molding process between the housings arranged in a row or column 4 of the semiconductor components 10 .
Normalerweise werden derartige Verbindungsstege 6 sogleich nach dem Entformen, d. h. nach dem Herausnehmen der hergestellten Teile aus dem Mouldwerkzeug, durch Brechen, Schneiden oder auf sonstige Art und Weise entfernt. Im vorliegenden Fall ist es vorteilhaft, die Verbindungsstege 6 nicht sofort, sondern erst zu einem späteren Zeitpunkt zu entfernen, so dass eine bestimmte Anzahl von Halbleiterbauelementen 10 über ihre Ge häusekörper 4 vorerst mit einander verbunden bleiben.Normally such connecting webs 6 are immediately after removal from the mold, that is removed after the removal of the parts produced from the Mouldwerkzeug, by breaking, cutting, or in any other manner. In the present case, it is advantageous not to remove the connecting webs 6 immediately, but only at a later point in time, so that a certain number of semiconductor components 10 initially remain connected to one another via their housing bodies 4 .
Das erleichtert einmal wesentlich die Handhabung während des Herstellpro zesses; es ermöglicht zudem, dass die mit einander verbundenen Halblei terbauelemente 10 gleichzeitig nachfolgenden Prozessschritte zugeführt werden können; weiterhin sorgt es für die gleiche Orientierung der Halblei terbauelemente 10, so dass beispielsweise beim Überprüfen der elektri schen Funktionsfähigkeit die Polarität sich nicht ändert.This greatly facilitates handling during the manufacturing process; it also enables the interconnected semiconductor components 10 to be simultaneously fed to subsequent process steps; it also ensures the same orientation of the semiconductor components 10 , so that, for example, the polarity does not change when checking the electrical functionality.
Eine zweite Möglichkeit zum Herstellen der Gehäusekörper 4 besteht darin, die gesamte Oberseite 1.1 mit dem als Vergussmasse dienenden thermopla stischen Kunststoff zu vergießen, so dass die Halbleiterbauelemente 10 wie bei der ersten Möglichkeit in einem Verbund zusammen geschlossen und damit beim Herstellprozess leichter handhabbar sind, als wenn die Halblei terbauelemente 10 sogleich vereinzelt werden. Die herzustellenden Halblei terbauelemente 10 werden später beispielsweise durch Sägen getrennt und somit vereinzelt. Auch bei dieser Möglichkeit ist es zweckmäßig, die Halblei terbauelemente 10 auf ihre elektrische Funktionsfähigkeit zu überprüfen, solange sie noch im Verbund angeordnet sind. A second way of producing the housing body 4 is to cast the entire top side 1.1 with the thermoplastic plastic serving as casting compound, so that the semiconductor components 10 are closed together as in the first possibility in a composite and are therefore easier to handle in the manufacturing process than if the semiconductor components 10 are immediately separated. The semiconductor components 10 to be produced are later separated, for example by sawing, and thus isolated. Even with this possibility, it is expedient to check the semiconductor components 10 for their electrical functionality as long as they are still arranged in the network.
Die Fig. 1d zeigt die bereits mit Strukturen, also Anschlussflächen 5.1 und 5.2 versehene Unterseite 1.2 des Substrats 1. Das Herstellen der Strukturen erfolgt durch Materialabtrennung mittels Laser, durch Ätzen oder durch Sägen. Vor der Materialabtrennung durch Ätzen muss zuerst die Unterseite 1.2 auf bekannte Art und Weise mit einem lichtempfindlichen Lack be schichtet, danach der Lack mittels Fotolithografie maskiert (d. h. an den ge wünschten Stellen belichtet) und das Substrat 1 darauf hin in ein Säurebad eingetaucht werden, so dass bei einer bestimmten Temperatur nach einer bestimmten Zeit das nicht mehr gebrauchte Material auf chemische Weise entfernt ist. Fig. 1d shows the already provided with structures, ie pads 5.1 and 5.2 1.2 underside of the substrate 1. The structures are produced by material separation using a laser, by etching or by sawing. Before the material is separated by etching, the underside 1.2 must first be coated in a known manner with a light-sensitive lacquer, then the lacquer masked using photolithography (ie exposed at the desired locations) and the substrate 1 then immersed in an acid bath, so that at a certain temperature, after a certain time, the material that is no longer used is removed chemically.
zur Orientierung für die herzustellenden Strukturen dienen die seitlichen Begrenzung des Substrats 1 oder die Transportöffnungen 8 in Verbindung mit einer abgeschnittenen Ecke 1.3.the lateral limitation of the substrate 1 or the transport openings 8 in connection with a cut corner 1.3 serve as orientation for the structures to be produced.
Es gibt auch verschiedene Möglichkeiten bei der zeitlichen Reihenfolge beim Herstellen der Strukturen auf der Unterseite 1.2. Eine erste Möglich keit besteht darin, das Substrat 1 in einem Teilbereich unterhalb der Gehäu sekörper 4 und gleichzeitig entlang der späteren Umrisse der elektrischen Anschlussflächen 5, 5.1 und 5.2 vollständig durchzutrennen, beispielsweise durch Ätzen. Damit sind dann in einem Schritt die Anschlussflächen 5, 5.1 und 5.2 elektrisch voneinander getrennt und somit isoliert und das Halblei terbauelement 10 aus dem Substrat herausgelöst. Die in einer Reihe ange ordneten Halbleiterbauelemente 10 sind dann nur noch mittels der Verbin dungsstege 6 miteinander verbunden und werden derart (wie dies in Fig. 3 dargestellt ist) nachfolgenden Fertigungsschritten zugeführt.There are also various options for the chronological order in which the structures on the underside 1.2 are produced . A first possibility is to completely cut through the substrate 1 in a partial area below the housing body 4 and at the same time along the later outlines of the electrical connection surfaces 5 , 5.1 and 5.2 , for example by etching. Thus, in one step, the connection surfaces 5 , 5.1 and 5.2 are electrically separated from one another and thus insulated and the semiconductor component 10 is detached from the substrate. The semiconductor devices 10 arranged in a row are then only connected to one another by means of the connecting webs 6 and are fed (as shown in FIG. 3) to subsequent production steps.
Eine weitere Möglichkeit besteht darin, lediglich den Teilbereich unterhalb der Gehäusekörper 4 zwischen den späteren Kontakten 5.1 und 5.2 durch zutrennen, beispielsweise durch Ätzen. In diesem Fall werden zu einem spä teren Zeitpunkt die dadurch entstandenen elektrischen Anschlussflächen (Anschlüsse) 5.1 und 5.2 verzinnt und die fertig aufgebauten Halbleiterbau elemente 10 in einem Trennvorgang (Schneiden, Sägen, Stanzen o. ä.) ver einzelt. Das Verzinnen der Anschlussflächen 5.1 und 5.2 kann auch nach dem Vereinzeln erfolgen, beispielsweise durch galvanisches Trommelverzin nen. A further possibility consists in severing only the portion below the housing body 4 between the later contacts 5.1 and 5.2 , for example by etching. In this case, the resulting electrical connection surfaces (connections) 5.1 and 5.2 are tinned at a later point in time and the finished semiconductor components 10 are separated in a separation process (cutting, sawing, punching or the like). The tinning of the connection surfaces 5.1 and 5.2 can also take place after the separation, for example by galvanic drum tinning.
Eine dritte Möglichkeit besteht darin, den Teilbereich unterhalb der Gehäu sekörper 4 zwischen den späteren Kontakten 5.1 und 5.2 durchzuätzen und das Substrat 1 entlang der späteren Umrisse der Gehäusekörper 4 lediglich anzuätzen. Dadurch wird entlang der späteren Umrisse der Gehäusekörper 4 eine Sollbruchstelle geschaffen, um die fertig aufgebauten Halbleiterbau elemente 10 zu einem späteren Zeitpunkt nach dem Verzinnen beispiels weise durch Brechen entlang dieser Sollbruchstellen zu vereinzeln.A third possibility consists in etching through the partial area below the housing body 4 between the later contacts 5.1 and 5.2 and only etching the substrate 1 along the later outline of the housing body 4 . As a result, a predetermined breaking point is created along the later outline of the housing body 4 in order to separate the finished semiconductor components 10 at a later time after tinning, for example by breaking along these predetermined breaking points.
Grundsätzlich kann bei allen beschriebenen Möglichkeiten das An- bzw. Durchätzen des Substrats 1 auch nach dem Verzinnen erfolgen.In principle, the substrate 1 can also be etched on or etched through after tinning in all the possibilities described.
In Fig. 2 sind mehrere, nach dem erfindungsgemäßen Verfahren hergestell te lichtaussendende Halbleiterbauelemente 10 dargestellt. In diesem Fall wurden zum Herstellen der Gehäusekörper 4 einzelne Kavitäten verwendet. Die Vergussmasse wurde durch Zuleitungen eines (nicht dargestellten) Mouldwerkzeugs gepresst, so dass nach dem Entformen dickere Verbin dungsstege 9 zu aus mehreren zusammen hängenden Halbleiterbauelemen ten 10 und Verbindungsstegen 6 bestehenden gefertigten Einheiten und die bereits beschriebenen Verbindungsstege 6 zwischen den Gehäusekör pern 4 vorhanden sind.In FIG. 2, a plurality, hergestell te process of the invention light-emitting semiconductor devices 10 are shown. In this case, 4 individual cavities were used to manufacture the housing body. The potting compound was pressed through feed lines of a mold tool (not shown), so that after demolding, thicker connecting webs 9 to units made of several interconnected semiconductor components 10 and connecting webs 6 and the connecting webs 6 already described between the housing bodies 4 are present.
Für die Handhabbarkeit der hergestellten Halbleiterbauelemente 10 bei nachfolgenden Fertigungsschritten ist es vorteilhaft, wenn zunächst an bei den Enden einer aus mehreren zusammen hängenden Halbleiterbauele menten 10 und Verbindungsstegen 6 bestehenden gefertigten Einheit je weils ein Angussstück 7.1 und 7.2 verbleibt. Zur Vermeidung von Missgriffen ist es hilfreich, wenn beispielsweise alle auf einer Seite angeordneten An gussstücke 7.2 eine kleine Vertiefung 7.3 oder eine sonstige formliche Be sonderheit als Missgriffssicherung aufweisen.For the manageability of the semiconductor components 10 produced in subsequent manufacturing steps, it is advantageous if at the ends of a unit consisting of a plurality of interconnected semiconductor components 10 and connecting webs 6 a unit each remains because of a sprue 7.1 and 7.2 . To avoid mistakes, it is helpful if, for example, all the castings 7.2 arranged on one side have a small depression 7.3 or some other formal feature to prevent misuse.
Mit Hilfe der zunächst nicht entfernten Angussstücke 7.1 und 7.2 kann bei spielsweise eine gefertigte Einheit nach dem Moulden aus dem Werkzeug entnommen werden, ohne dass die Halbleiterbauelemente 10 berührt und dadurch möglicherweise beschädigt werden. Weiterhin kann die gefertigte Einheit beim Heraustrennen aus dem Substrat 1 an diesen Angussstücken 7.1 und 7.2 gegriffen und danach zum Verzinnen der elektrischen Anschlüs se 5 (Fig. 3) in ein Galvanikbad eingetaucht werden. With the help of the cast-on pieces 7.1 and 7.2 , which were initially not removed, a manufactured unit can be removed from the tool after molding, for example, without touching the semiconductor components 10 and possibly being damaged thereby. Furthermore, the finished unit can be gripped from these substrates 7.1 and 7.2 when it is separated from the substrate 1 and then immersed in an electroplating bath for tinning the electrical connections 5 ( FIG. 3).
Fig. 3 zeigt drei noch mittels Verbindungsstegen 6 verbundene, nach dem erfindungsgemäßen Verfahren hergestellte lichtaussendende Halbleiter bauelemente 10 vor dem Galvanikprozess zum Verzinnen der elektrischen Anschlüsse 5. Jedes Halbleiterbauelement 10 weist neben dem (nicht sicht baren) Halbleiterkörper 2 einen transparenten Gehäusekörper 4 und aus Anode 5.1 und Kathode 5.2 bestehende elektrische Anschlüsse 5 auf. Beim Galvanikprozess werden die durch Verbindungsstege 6 verbundenen Halb leiterbauelemente 10 verzinnt, d. h. mit den elektrischen Anschlüssen nach unten soweit in ein Bad aus flüssigem Zinn abgesenkt, bis die aus einer Kup ferlegierung bestehenden Anschlüsse 5 vollständig ins Zinnbad eingetaucht sind. FIG. 3 shows three light-emitting semiconductor components 10 , which are still connected by means of connecting webs 6 and are produced by the method according to the invention before the electroplating process for tinning the electrical connections 5 . In addition to the (not visible) semiconductor body 2, each semiconductor component 10 has a transparent housing body 4 and electrical connections 5 consisting of anode 5.1 and cathode 5.2 . When electroplating process, connected by connecting webs 6 half-conductor devices to be plated 10, that is lowered so far with the electrical terminals downwardly into a bath of liquid tin, until the ferlegierung from a Kup existing terminals 5 completely immersed into the tin bath.
Nach dem Herausziehen der noch mit einander verbundenen Halbleiterbau elemente 10 aus dem Zinnbad sind die Anschlüsse 5 mit einer Schicht aus Zinn überzogen, um sie vor Oxidation zu schützen. Nach dem Verzinnen der elektrischen Anschlüsse 5 werden die Verbindungsstege 6 entfernt, bei spielsweise durch Sägen, Schneiden, Stanzen oder Brechen, und somit die Halbleiterbauelemente 10 vereinzelt.After pulling out the still connected semiconductor components 10 from the tin bath, the connections 5 are coated with a layer of tin to protect them from oxidation. After tinning the electrical connections 5 , the connecting webs 6 are removed, for example by sawing, cutting, punching or breaking, and thus the semiconductor components 10 are separated.
Das Verzinnen der elektrischen Anschlüsse 5 mittels eines Galvanikprozesses kann vor oder nach dem Strukturieren der Unterseite 1.2, vor oder nach dem Vereinzeln der Halbleiterbauelemente 10 oder auch dann erfolgen, nachdem mehrere mittels Verbindungsstegen 6 miteinander verbundene Halbleiterbauelemente 10 aus dem Substrat 1 herausgetrennt worden sind.Tinning of the electrical terminals 5 by means of a galvanic process can take place before or after the patterning of the bottom 1.2, before or after dicing of the semiconductor components 10 or be made even after several have been separated from the substrate 1 by means of connecting webs 6 interconnected semiconductor devices 10th
Fig. 4 zeigt die Unterseite eines vereinzelten, nach dem erfindungsgemä ßen Verfahren hergestellten lichtaussendenden Halbleiterbauelements 10 mit elektrischen Anschlüssen 5.1 (Anode) und 5.2 (Kathode), bei dem noch Reste 6.1 eines zuvor abgetrennten Verbindungsstegs 6 zu sehen sind. Die Unterseite des fertig gestellten Halbleiterbauelements 10 ist identisch mit der Unterseite 1.2 des jetzt nicht mehr vorhandenen Substrats 1. Da das (hier nicht sichtbare) Halbleiterchip 2 direkt mit dem vergleichsweise groß flächigen elektrischen Anschluss 5.2 verbunden ist, kann die im Halbleiter chip 2 entstehende Wärme problemlos abgeführt werden. FIG. 4 shows the underside of an isolated light-emitting semiconductor component 10 produced by the method according to the invention with electrical connections 5.1 (anode) and 5.2 (cathode), in which remnants 6.1 of a previously separated connecting web 6 can still be seen. The underside of the finished semiconductor component 10 is identical to the underside 1.2 of the substrate 1 that is no longer present. Since the (not visible here) semiconductor chip 2 is directly connected to the comparatively large-area electrical connection 5.2, the chip 2 in the semiconductor resulting heat can be removed easily.
Fig. 5a zeigt eine perspektivische Ansicht eines nach dem erfindungsgemä ßen Verfahren hergestellten Halbleiterbauelements 10 in Form einer Micro- SMD-Leuchtdiode mit seinen elektrischen Anschlüssen 5.1 und 5.2, dem Halbleiterchip 2, dem Bonddraht 3.1 und dem transparenten Gehäusekör per 4. Die Außenmaße des Halbleiterbauelements 10 betragen ca. 0,8 mm in der Breite, ca. 1,7 mm in der Länge und ca. 0,6 mm in der Höhe. FIG. 5a is a perspective view showing a semiconductor device 10 manufactured according to the inventive SEN method in the form of a micro-SMD light-emitting diode with its electrical terminals 5.1 and 5.2, the semiconductor chip 2, the bonding wire 3.1 and the transparent Gehäusekör per 4. The external dimensions of the semiconductor component 10 are approximately 0.8 mm in width, approximately 1.7 mm in length and approximately 0.6 mm in height.
In Fig. 5b sind zudem noch weitere Maße eines Halbleiterbauelements 10 dargestellt. Demnach beträgt die Breite jedes elektrischen Anschlusses 5.1 Und 5.2 jeweils 0,7 mm, der Abstand dazwischen 0,3 mm. Das Halbleiterchip 2, bei dem es sich in diesem Fall um ein lichtaussendendes LED-Chip handelt, weist eine quaderförmige, fast würfelförmige Gestalt mit den Maßen von ungefähr 0,3 mm × 0,3 mm × 0,25 mm auf.In Fig. 5b will have other dimensions of a semiconductor device 10 are shown. Accordingly, the width of each electrical connection 5.1 and 5.2 is 0.7 mm, the distance between them is 0.3 mm. The semiconductor chip 2 , which in this case is a light-emitting LED chip, has a cuboid, almost cube-shaped shape with the dimensions of approximately 0.3 mm × 0.3 mm × 0.25 mm.
Verkleinerte Abmessungen werden erreicht, wenn der Bonddraht 3.1 nicht bogenförmig, sondern ungefähr rechteckig abgewinkelt vom Halbleiterchip 2 zur Anode 5.1 verläuft. Dadurch wird die Höhe des Halbleiterbauelements 10 um ca. 50 µm vermindert. Die Länge des Halbleiterbauelements 10 von 1,7 mm kann um wenigstens 0,5 mm verkürzt werden, wenn die Anode 5.1 verkürzt und der Abstand zur Kathode 5.2 verringert wird. Die verkürzte Anode 5.1 ist damit auch optisch leicht von der Kathode 5.2 zu unterschei den.Reduced dimensions are achieved if the bonding wire 3.1 does not run in an arc shape, but rather is angled approximately rectangularly from the semiconductor chip 2 to the anode 5.1 . The height of the semiconductor component 10 is thereby reduced by approximately 50 μm. The length of the semiconductor component 10 of 1.7 mm can be shortened by at least 0.5 mm if the anode 5.1 is shortened and the distance to the cathode 5.2 is reduced. The shortened anode 5.1 is thus easy to distinguish optically from the cathode 5.2 .
Die Fig. 5c-e zeigen perspektivische Ansichten mehrerer nach dem erfin dungsgemäßen Verfahren hergestellter Halbleiterbauelemente 10 mit in den Gehäusekörper 4 integrierten optischen Auskopplungen und Ankopp lungen. So zeigt Fig. 5c ein Halbleiterbauelement 10 mit einer in den Ge häusekörper 4 integrierten sphärische oder asphärische Linse 18. Eine gün stiger herzustellende zylindrische Linse 19, die in den Gehäusekörper 4 ei nes Halbleiterbauelements 10 integriert ist, ist in Fig. 5d dargestellt. Und aus der Fig. 5e geht eine Aufnahme 20 mit einer Öffnung 21 hervor. Die Öffnung 21 dient beispielsweise dazu, einen (nicht dargestellten) Lichtwel lenleiter anzukoppeln, indem der Lichtwellenleiter in diese Öffnung 21 ein gesteckt wird. Weitere Linsenformen und optische Ankopplungen, wie sie von Leuchtdioden her bekannt sind, sind ebenfalls problemlos herstellbar. FIG. 5c-e show perspective views of several lungs after OF INVENTION The method to the invention produced semiconductor devices 10 with integrated into the housing body 4 and the optical outcoupling Ankopp. 5c shows as Fig. 10, a semiconductor device with a built in the Ge 4 häusekörper spherical or aspherical lens 18. A gün stiger cylindrical lens 19 , which is integrated in the housing body 4 egg nes semiconductor device 10 is shown in Fig. 5d. And from Fig. 5e 20 is a receiving opening 21 with a forth. The opening 21 is used, for example, to couple an optical waveguide (not shown) by inserting the optical waveguide into this opening 21 . Other lens shapes and optical couplings, as are known from light-emitting diodes, can also be produced without problems.
Fig. 6 zeigt perspektivische Darstellungen zur Erläuterung verschiedener Arbeitsschritte einer zweiten Version des erfindungsgemäßen Herstellungs verfahrens, wiederum am Beispiel lichtaussendender Halbleiterbauelemente 10, die auch auf einem Substrat, diesmal jedoch in Form eines länglichen metallenen Trägerband 11 in Reihen aufgebaut werden. Fig. 6 shows perspective views for explaining various steps of a second version of the manufacturing method according to the invention, again using the example of light-emitting semiconductor components 10 , which are also built on a substrate, but this time in the form of an elongated metal carrier tape 11 in rows.
Wie bei der ersten Version des erfindungsgemäßen Herstellungsverfahrens wird in den meisten Fällen zu einem bestimmten Zeitpunkt an allen auf dem Substrat 11 aufzubauenden Halbleiterbauelementen 10 nur ein bestimmter Arbeitsschritt (z. B. Bestücken, Bonden, Moulden) ausgeführt. Mit besonders aufgebauten Fertigungsmaschinen ist es aber auch möglich, verschiedene Arbeitsschritte parallel auszuführen, beispielsweise Aufkleben eines Halblei terchips 2 und anschließend sofort Drahtbonden.As in the first version of the manufacturing method according to the invention, in most cases only a certain working step (eg assembly, bonding, molding) is carried out on all the semiconductor components 10 to be built up on the substrate 11 . With specially constructed manufacturing machines, it is also possible to carry out different work steps in parallel, for example gluing a semiconductor chip 2 and then immediately wire bonding.
Beispielsweise wird gemäß der Fig. 6 zu einem bestimmten Zeitpunkt an einer ersten Arbeitsstation 12 ein Halbleiterchip 2 mittels eines leitfähigen Klebstoffs, mittels eines Lotes oder durch thermisches Chipbonden, jeweils bei entsprechend ausgestalteten Rückseitenkontakten der Halbleiterchips 2, auf der Oberseite des Trägerbands 11 kontaktiert. Danach wird an einer zweiten Arbeitsstation 13 der Vorderseitenkontakt des Halbleiterchips 2 mittels eines Bonddrahtes 3.1 mit der Oberfläche des Trägerbandes 11 ver bunden, darauf hin an einer dritten Arbeitsstation 14 der Halbleiterchip 2 samt dem Bonddraht 3.1 mit einem Gehäusekörper 4 aus transparentem, thermoplastischem Kunststoff eingekapselt, wobei Verbindungsstege 6 ent stehen, später an einer vierten Arbeitsstation 15 die Unterseite des Träger bandes 11 strukturiert und zuletzt an einer fünften Arbeitsstation 16 die elektrischen Anschlüsse 5 der Halbleiterbauelemente 10 verzinnt.For example, the FIG invention. Contacted 6 at a certain time at a first work station 12, a semiconductor chip 2 by a conductive adhesive, by means of a solder or thermal die bonding, in each case in appropriately designed back contacts of the semiconductor chips 2 on the upper side of the carrier tape 11. The front side contact of the semiconductor chip 2 is then connected to the surface of the carrier tape 11 by means of a bonding wire 3.1 at a second work station 13, and then the semiconductor chip 2 together with the bonding wire 3.1 is encapsulated with a housing body 4 made of transparent, thermoplastic plastic at a third work station 14 , where connecting webs 6 are ent, later structured the underside of the carrier tape 11 at a fourth work station 15 and finally tinned the electrical connections 5 of the semiconductor components 10 at a fifth work station 16 .
An weiteren Arbeitsstationen werden beispielsweise die fast fertiggestell ten Halbleiterbauelemente 10 mittels Prüfspitzen 17 auf ihre Funktion hin getestet und die Verbindungsstege 6 entfernt. Beliebige weitere Arbeits schritte können folgen, wie z. B. Reinigung und Verpackung.At other workstations, for example, the almost finished semiconductor components 10 are tested for their function by means of test probes 17 and the connecting webs 6 are removed. Any other work steps can follow, such as. B. Cleaning and packaging.
Das am Beispiel vom lichtaussendenden Halbleiterbauelementen (Micro-SMD- Leuchtdiode) in zwei Versionen beschriebene Verfahren eignet sich auch für die Herstellung anderer oberflächenmontierter elektronischer Halbleiter bauelemente mit sehr kleinen Abmessungen, wie mehrfarbige Leucht dioden, Dioden, Transistoren und integrierte Schaltkreise. Hierfür ist in vie len Fällen die Verwendung lichtundurchlässiger Vergussmasse sinnvoll. Be nötigt ein Halbleiterbauelement mehr als zwei elektrische Anschlüsse, wie dies bei mehrfarbigen Leuchtdioden, Transistoren und vor allem bei inte grierten Schaltkreisen der Fall ist, muss die Strukturierung des Substrats (Trägerplatte oder Trägerband) entsprechend angepasst werden, was je doch für einen einschlägigen Fachmann kein Problem darstellt. Die anfangs genannten Vorteile des erfindungsgemäßen Herstellverfahrens bleiben auch bei derartigen Modifikationen voll erhalten.The example of light-emitting semiconductor components (micro-SMD The method described in two versions is also suitable for the manufacture of other surface mount electronic semiconductors components with very small dimensions, such as multi-colored lights diodes, diodes, transistors and integrated circuits. For this is in vie len cases, the use of opaque potting compound makes sense. Be a semiconductor device requires more than two electrical connections, such as this with multicolored LEDs, transistors and especially with inte circuitry is the case, the structuring of the substrate (Carrier plate or carrier tape) can be adjusted accordingly, depending on but not a problem for a relevant specialist. The beginning mentioned advantages of the manufacturing method according to the invention remain fully preserved even with such modifications.
