Description
Die Erfindung betrifft eine Abdeckung für optische Sensoren, bestehend aus einem Sensorchip mit einer Sensorfläche, die mit Filter- bzw. Farbschichten abgedeckt ist und wobei der Sensorchip auf einem Substrat montiert und mit diesem elektrisch verbunden ist.The The invention relates to a cover for optical sensors, consisting from a sensor chip with a sensor surface, with filter or ink layers is covered and wherein the sensor chip mounted on a substrate and is electrically connected to this.
Bei optischen Sensoren können sich auf sensitiven Bereichen optisch definierte Schichten, z.B. Farbschichten aus strukturierten organischen Materialien, befinden, die bei Farbsensoren, z.B. Imager, Photodioden, Phototransistoren, überhaupt erst in die Voraussetzung schaffen, dass Farbe oder andere optische Größen detektiert werden können. Werden diese Sensoren mittels COB-Technologie (Chip & Wire oder Flip Chip) montiert, ist es wünschenswert, die empfindlichen Schichten zu schützen, was mit Hilfe von Glasabdeckungen grundsätzlich möglich ist, jedoch ist eine direkte Montage von Glasabdeckungen, Filtern o.ä. unmittelbar auf diesen Schichten aus physikalischen und mechanischen Gesichtspunkten nicht zulässig.at optical sensors can on optically sensitive areas optically defined layers, e.g. layers of paint made of structured organic materials that are used in color sensors, e.g. Imagers, photodiodes, phototransistors, in the first place in the condition create that color or other optical quantities can be detected. Be this Sensors using COB technology (chip & wire or flip chip) mounted is it desirable that to protect sensitive layers, which is basically possible with the help of glass covers, however, is one direct mounting of glass covers, filters or similar directly on these layers not permitted for physical and mechanical reasons.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Abdeckung für optische Sensoren zu schaffen, die einerseits einfach montiert werden kann und andererseits einen zuverlässigen Schutz der Farbschichten auf der Sensorfläche bieten.Of the Invention is therefore based on the object, a cover for optical Creating sensors that can be easily mounted on the one hand and on the other hand a reliable one Provide protection of the color layers on the sensor surface.
Die der Erfindung zugrunde liegende Aufgabe wird bei einer Abdeckung für einen Farbbildsensor der eingangs genannten Art dadurch gelöst, dass die Abdeckung aus Glas- oder Kunststoff besteht, die in einem Abstand mindestens über der Sensorfläche angeordnet ist und wobei der Abstand durch Abstandselemente zwischen der Sensorfläche und der Glas- oder Kunststoffscheibe definiert ist.The The object underlying the invention is in a cover for one Color sensor of the type mentioned solved by that the cover is made of glass or plastic, which is at a distance at least over the sensor surface arranged is and wherein the distance by spacers between the sensor surface and the glass or plastic disc is defined.
Eine solche Abdeckung lässt sich besonders einfach realisieren, wobei als einzige Voraussetzung berücksichtigt werden muss, dass auf der Oberfläche des Sensorchips um die Sensorfläche herum genügend Freiraum zur Montage der Abdeckung vorhanden ist. Die die Sensorzeile abdeckende Farbschicht muss also kleiner sein, als die Chipfläche.A leaves such cover be particularly easy to implement, taking into account as the only requirement must be that on the surface of the Sensor chips around the sensor surface enough Free space for mounting the cover is present. The sensor line covering color layer must therefore be smaller than the chip area.
Eine besonders günstige Ausgestaltung der Erfindung sieht vor, dass die Abdeckung als Kappe ausgebildet ist, die auf des Sensorchip aufgeklebt ist, wobei die Kappe die Sensorfläche auf dem Sensorchip vollständig umschließen kann.A especially cheap Embodiment of the invention provides that the cover is formed as a cap which is glued to the sensor chip, the cap is the sensor surface completely on the sensor chip enclose can.
Besteht die Abdeckung in einer besonderen Variante der Erfindung aus einem Glas- oder Kunststofffenster, so sind zusätzliche Abstandselemente vorgesehen, die einen Rahmen bilden. Der Rahmen umgibt dabei die Sensorfläche und ist sowohl mit der Glasscheibe oder dem Kunststofffenster als auch mit dem Sensorchip unlösbar verklebt.Consists the cover in a particular variant of the invention from a Glass or plastic windows, so additional spacers are provided, which form a frame. The frame surrounds the sensor surface and is with both the glass or the plastic window as well insoluble with the sensor chip bonded.
In einer Fortführung der Erfindung bestehen die Abstandselemente aus einem vorgefertigten Rahmen z.B. aus Glas, Polymerwerkstoffen oder Metallen.In a continuation the invention consist of the spacer elements of a prefabricated frame e.g. made of glass, polymer materials or metals.
In einer weiteren praktischen Ausgestaltung der Erfindung wird der Polymerwerkstoff bzw. der Klebstoff durch Drucken oder Dispensen auf den Sensorchip, die Sensorfläche umrandend, aufgebracht.In Another practical embodiment of the invention is the Polymer material or the adhesive by printing or dispensing on the sensor chip, the sensor surface bordering, applied.
Schließlich kann vorgesehen sein, dass die Abmessungen der Glass-oder des Kunststofffensters den Abmessungen des Sensorchips entsprechen.Finally, can be provided that the dimensions of the glass or the plastic window the Dimensions of the sensor chip correspond.
Weiterhin kann der Zwischenraum einerseits zwischen der Abdeckung und der Sensorfläche mit Luft oder einem anderen Gas gefüllt werden, oder andererseits evakuiert werden, so dass ein besonderer atmosphärischer Schutz für die Farbschicht erreicht werden kann.Farther the space between the cover and the sensor surface be filled with air or another gas, or otherwise be evacuated, giving a special atmospheric protection for the paint layer can be achieved.
Auch kann die Abdeckung mit einer Beschichtung versehen sein.Also the cover may be provided with a coating.
Eine besondere Weiterführung der Erfindung ist dadurch gekennzeichnet, dass eine Vielzahl von Sensorchips im Waferverbund nebeneinander angeordnet sind und dass die Abdeckungen zumindest eine Gruppe von Sensorchips gleichzeitig in einem Montageprozess abdecken. Die nachfolgende Vereinzelung in Farbbildsensoren kann dann mit üblichen Trennverfahren, wie Trennsägen, erfolgen. Der Vorteil ist hier in der besonders kostengünstigen, weil parallelen Fertigung zu sehen.A special continuation The invention is characterized in that a plurality of sensor chips in the wafer assembly are arranged side by side and that the covers at least one group of sensor chips simultaneously in an assembly process cover. The subsequent separation in color image sensors can then with usual Separation processes, such as cutting saws, respectively. The advantage here is in the particularly cost-effective, because to see parallel manufacturing.
Die Abdeckung auf dem Waferverbund kann bevorzugt ein strukturierter Glaswafer oder auch ein Linsenarray sein. Das Linsenarray kann dabei als ein gespritztes Linsenarray ausgeführt sein, was besonders kostengünstig hergestellt werden kann.The Cover on the wafer composite may preferably be a structured Glass wafer or a lens array. The lens array can do this be designed as a sprayed lens array, which produced particularly inexpensive can be.
Die Erfindung soll nachfolgend an Ausführungsbeispielen näher erläutert werden. In den zugehörigen Zeichnungen zeigen:The Invention will be explained in more detail below by exemplary embodiments. In the associated Drawings show:
