Description
Die Erfindung betrifft ein Leuchtelement mit wenigstens einer Halbleiterstruktur, welche bei Spannungsbeaufschlagung elektromagnetische Strahlung emittiert, und einem die Halbleiterstruktur tragenden Trägersubstrat.The The invention relates to a luminous element having at least one semiconductor structure, which emits electromagnetic radiation when exposed to voltage, and a carrier substrate supporting the semiconductor structure.
Üblicherweise werden bei derartigen Leuchtelementen, die beispielsweise in LEDs verwendet werden, die Halbleiterstrukturen aus einem EPI-Wafer, d.h. einem aus einem Halbleiter-Einkristall geschnittenen Wafer, gefertigt. Die Halbleiterstrukturen werden hierfür mittels an und für sich bekannter fotolithografischer und/oder Trockenätz-Verfahren aus dem EPI-Wafer aufgebaut. Das Trägersubstrat ist dabei häufig aus dem Wafermaterial selbst gebildet, welches wiederum die aufgebaute Halbleiterstruktur trägt. Der Wafer muß dann folglich ausreichend dick geschnitten sein, damit das fertiggestellte Leuchtelement eine hinreichende mechanische Stabilität und Festigkeit aufweist. Der erreichbaren mechanischen Belastbarkeit sind jedoch bereits durch die Sprödheit des Wafers selbst Grenzen gesetzt. Darüber hinaus geht dasjenige Material des Wafers, welches beim fertigen Leuchtelement als Trägersubstrat dient, für die Ausbildung von Halbleiterstrukturen verloren.Usually be in such lighting elements, for example, in LEDs be used, the semiconductor structures of an EPI wafer, i.e. a wafer cut from a semiconductor single crystal, manufactured. The semiconductor structures are known for this purpose by means of per se Photolithographic and / or dry etching process built from the EPI wafer. The carrier substrate is common formed from the wafer material itself, which in turn built up the Semiconductor structure carries. The wafer must then Consequently, cut sufficiently thick for the finished Luminous element of sufficient mechanical stability and strength having. The achievable mechanical strength, however already by the brittleness of the Wafers set limits themselves. In addition, that material goes of the wafer, which in the finished luminous element as a carrier substrate serves, for the Training of semiconductor structures lost.
Die Halbleiterstruktur kann jedoch auch von einem Trägersubstrat aus einem anderen Material als demjenigen des Wafers getragen sein. Auch in diesem Fall wird die Stabilität des Leuchtelements durch das Trägersubstrat gewährleistet.The However, semiconductor structure may also be from one carrier substrate to another Material to be worn as that of the wafer. Also in this Case becomes stability of the luminous element by the carrier substrate guaranteed.
Aufgabe der Erfindung ist es, ein Leuchtelement der eingangs genannten Art zu schaffen, dessen Herstellungskosten gesenkt sind. Darüber hinaus ist es Aufgabe der Erfindung, ein Leuchtelement der eingangs genannten Art bereitzustellen, dessen mechanische Belastbarkeit erhöht ist.task The invention is a luminous element of the type mentioned to create whose production costs are reduced. Furthermore It is an object of the invention to provide a luminous element of the aforementioned To provide type whose mechanical strength is increased.
Dies wird bei einem Leuchtelement der eingangs genannten Art dadurch erreicht, daß das Trägersubstrat seinerseits von einem Basissubstrat getragen ist.This is characterized in a luminous element of the type mentioned by achieved that carrier substrate itself supported by a base substrate.
Diese Ausbildung des Leuchtelements bietet die Möglichkeit, daß, wenn das Trägersubstrat aus dem Wafer-Material gebildet ist, weniger Wafer-Material als Trägersubstrat verwendet werden muß. Das Trägersubstrat aus Wafer-Material kann also dünner als bei bekannten Leuchtelementen ausgebildet sein. Dadurch wird Wafer-Material gespart und die Herstellungskosten werden insgesamt gesenkt. Die geforderte mechanische Stabilität und Belastbarkeit des Leuchtelements kann durch eine entsprechende Wahl des Materials für das Basissubstrat erzielt werden.These Formation of the luminous element offers the possibility that, if the carrier substrate formed from the wafer material, less wafer material than carrier substrate must be used. The carrier substrate made of wafer material can be thinner than be formed in known lighting elements. This will make wafer material saved and the production costs are reduced overall. The required mechanical stability and load capacity of the luminous element can by an appropriate choice of the material for the base substrate can be achieved.
Dabei ist es insbesondere vorteilhaft, wenn das Basissubstrat ein Glasmaterial, insbesondere ein Bor-Tonerde-Glas umfaßt. Bei der Verwendung derartiger Gläser haben sich Glasmaterialien als günstig erwiesen, deren Zusammensetzung etwa einer Zusammensetzung von a) 81% SiO2, 13% B2O3, 4% Alkali, 2% Al2O3 oder b) 57% SiO2, 1% Na2O, 12% MgO, 26% Al2O3, 4% B2O3 entspricht.It is particularly advantageous if the base substrate comprises a glass material, in particular a boron-alumina glass. When using such glasses, glass materials have proved to be favorable, the composition of which has a composition of a) 81% SiO 2 , 13% B 2 O 3 , 4% alkali, 2% Al 2 O 3 or b) 57% SiO 2 , 1% Na 2 O, 12% MgO, 26% Al 2 O 3 , 4% B 2 O 3 .
Derartige handelsübliche Glasmaterialien weisen gute mechanische Eigenschaften auf und sind zudem weitgehend unempfindlich gegen Temperaturschwankungen und sonstige äußere Einflüsse. Darüberhinaus sind sie über einen verhältnismäßig großen Wellenlängenbereich transparent.such commercial Glass materials have good mechanical properties and are also largely insensitive to temperature fluctuations and other external influences. Furthermore are they over a relatively large wavelength range transparent.
Alternativ kann das Basissubstrat auch eine Keramik oder ein Metall, insbesondere Kupfer oder Aluminium, umfassen. Auch solches Material verringert die Herstellungskosten des Leuchtelements, da weniger Wafer-Material als Trägersubstrat verwendet werden muss.alternative For example, the base substrate may also be a ceramic or a metal, in particular Copper or aluminum. Even such material is reduced the manufacturing cost of the luminous element, since less wafer material as a carrier substrate must be used.
Die gewünschte Hauptabstrahlrichtung eines Leuchtelements ist üblicherweise die dem Trägersubstrat entgegengesetzte Richtung, wobei eine Halbleiterstruktur normalerweise Licht in im wesentlichen alle Raumrichtungen emittiert. Um die Lichtausbeute des Lichtelements zu erhöhen, ist es dienlich, wenn das Trägersubstrat und das Basismaterial zumindest teilweise für die von der Halbleiterstruktur emittierte Strahlung transparent sind und die dem Trägersubstrat gegenüberliegende Seite des Basissubstrats mit einer diese Strahlung in Richtung auf das Trägersubstrat reflektierenden Schicht versehen ist. Strahlt nämlich die Halbleiterstruktur unter Spannungsbeaufschlagung Licht durch das transparente Basissubstrat hindurch ab, so wird dieses Licht von der reflektierenden Schicht in Richtung auf die gewünschte Hauptabstrahlrichtung des Leuchtelements reflektiert und trägt zusätzlich zur Lichtausbeute des Leuchtelements bei.The desired The main emission direction of a luminous element is usually that of the carrier substrate opposite direction, with a semiconductor structure normally Light emitted in essentially all spatial directions. To the light output to increase the light element, it is useful if the carrier substrate and the base material at least partially for the emitted from the semiconductor structure Radiation are transparent and the carrier substrate opposite Side of the base substrate with a radiation in the direction of the carrier substrate reflective layer is provided. It radiates the semiconductor structure under stress, light through the transparent base substrate Through, this light is from the reflective layer towards the desired Main emission of the light element reflects and contributes in addition to Luminous efficiency of the light element at.
In der Praxis hat es sich als vorteilhaft erwiesen, wenn das Basissubstrat eine Dicke von 0,5 mm bis 2,0 mm, bevorzugt von 0,75 mm bis 1,5 mm und nochmals bevorzugt von etwa 1,0 mm hat. Bei diesen Dicken des Basissubstrats wird eine gute mechanische Stabilität des Leuchtelements erreicht.In In practice, it has proved to be advantageous if the base substrate a thickness of 0.5 mm to 2.0 mm, preferably 0.75 mm to 1.5 mm and more preferably about 1.0 mm. At these thicknesses of the base substrate becomes a good mechanical stability of the luminous element reached.
Es ist günstig, wenn das Trägersubstrat ein Glasmaterial oder ein Kristallmaterial umfaßt. In diesem Fall wird nochmals Wafer-Material bei der Herstellung des Leuchtelements gespart, da nunmehr lediglich die Halbleiter struktur aus Wafer-Material aufgebaut ist und diese von dem Trägersubstrat aus einem anderem Material getragen sind.It is cheap, when the carrier substrate a glass material or a crystal material. In this case will be again Wafer material saved in the production of the luminous element, since now only the semiconductor structure constructed of wafer material is and this from the carrier substrate are worn from a different material.
Dabei ist es dienlich, wenn das Trägersubstrat ein Al2O3-Material umfaßt. Ein derartiges Material, welches als Korundglas oder auch als Saphirglas bekannt ist, ist transparent und gut als Trägermaterial für eine Halbleiterstruktur geeignet. Durch die Transparenz kann auch nach hinten abgestrahltes Licht verwendet werden, was bereits oben im Zusammenhang mit einer reflektierenden Schicht angesprochen wurde. Bei Verwendung eines Basissubstrats aus einem Keramikmaterial oder einem Metall kann das Basissubstrat selbst als reflektierende Schicht dienen.It is useful if the carrier substrate comprises an Al 2 O 3 material. Such a material, which be as corundum or as sapphire be is transparent and is well suited as a carrier material for a semiconductor structure. Due to the transparency, light emitted to the rear can also be used, which has already been mentioned above in connection with a reflective layer. When using a base substrate of a ceramic material or a metal, the base substrate itself may serve as a reflective layer.
Ein Al2O3-Material weist zudem eine besonders große Härte auf. Zudem ist ein Saphirglas auch chemisch besonders beständig und daher auch als Unterlage bei fotolithografischen Verfahren, wie sie zur Erzeugung der Halbleiterstruktur angewendet werden, gut verwendbar.An Al 2 O 3 material also has a particularly high hardness. In addition, a sapphire crystal is also chemically particularly stable and therefore also useful as a support in photolithographic processes, as they are used to produce the semiconductor structure, well usable.
Im Hinblick auf das Trägersubstrat ist es vorteilhaft, wenn dieses eine Dicke von 5 μm bis 400 μm, bevorzugt von 5 μm bis 200 μm, nochmals bevorzugt von 10 μm bis 100 μm und nochmals bevorzugt von 50 μm bis 75 μm hat.in the With regard to the carrier substrate it is advantageous if this a thickness of 5 microns to 400 microns, preferably of 5 μm up to 200 μm, more preferably 10 microns up to 100 μm and more preferably 50 μm up to 75 μm Has.
Es ist besonders günstig, wenn mindestens eine Halbleiterstruktur eine erste Halbleiterschicht, eine zweite Halbleiterschicht und eine dazwischen angeordnete MQW-Schicht umfaßt. Bei einer derartigen Halbleiterstruktur wird die dem Leuchtelement zugeführte elektrische Energie mit besonders hohem Wirkungsgrad in Licht umgesetzt. Ergänzend läßt sich das Spektrum durch die MQW-Schicht beeinflussen.It is particularly cheap if at least one semiconductor structure comprises a first semiconductor layer, a second semiconductor layer and an MQW layer interposed therebetween includes. In such a semiconductor structure, the light supplied to the lighting element is electrical Energy with particularly high efficiency converted into light. In addition can be affect the spectrum through the MQW layer.
Eine hohe Lichtausbeute in der Halbleiterstruktur läßt sich insbesondere damit erreichen, daß die erste Halbleiterschicht ein III-V-Material umfaßt.A high luminous efficacy in the semiconductor structure can be particularly so achieve that first semiconductor layer comprises a III-V material.
