Technische AufgabeTechnical task
Es ist deshalb eine Aufgabe der vorliegenden Erfindung, die Nachteile des Standes der Technik zu umgehen, und eine verbesserte Aufnahmevorrichtung und ein Verfahren zur Herstellung derselben bereitzustellen.It is therefore an object of the present invention to obviate the disadvantages of the prior art and to provide an improved receiving device and a method for making the same.
Technische LösungTechnical solution
Diese Aufgabe wird durch die Merkmale des Verfahrensanspruchs 1 gelöst.This object is achieved by the features of method claim 1.
Hierzu schlägt die Erfindung ein Verfahren zur Herstellung einer optische Aufnahmevorrichtung vor, welches ein mit einer elektrischen Schaltungsstruktur versehenes optisch transparentes Trägerelement bereitstellt; einen optischen Aufnahmechip bereitstellt, welcher auf mindestens einer Seite mit Kontaktstellen aus einem elektrisch leitfähigen Material versehen ist; wobei ein optisch transparentes und elektrisch nicht leitfähiges Haftmittel auf das Trägerelement aufgebracht wird; und wobei der Aufnahmechip in das Haftmittel eingebettet wird, wobei die Kontaktstellen einer Seite des Aufnahmechips in das Haftmittel eingetaucht und mit elektrischen Kontakten der Schaltungsstruktur des Trägerelements elektrisch leitend kontaktiert werden.To this end, the invention proposes a method for producing an optical recording device which provides an optically transparent carrier element provided with an electrical circuit structure; providing an optical recording chip which is provided on at least one side with contact points made of an electrically conductive material; wherein an optically transparent and electrically non-conductive adhesive is applied to the carrier element; and wherein the receiving chip is embedded in the adhesive, the contact points on one side of the receiving chip being immersed in the adhesive and electrically conductively contacted with electrical contacts of the circuit structure of the carrier element.
Vorteilhafte WirkungenBeneficial effects
Vorteilig an dem Verfahren gemäß der Erfindung ist zum einen, dass durch die Verbindung des Aufnahmechips mit dem Trägerelement mittels Haftmittel bei gleichzeitiger elektrischer Verbindung zwischen Aufnahmechip und Trägerelement relativ viel Platz eingespart wird, da die Verdrahtung und das Gehäuse entfallen. Zum anderen ist der Aufnahmechip relativ gut gegenüber Kontaminationen geschützt, da Kontaminationen nur relativ schwer zwischen Haftmittelschicht und Aufnahmechip gelangen können.The advantage of the method according to the invention is, on the one hand, that by connecting the receiving chip to the carrier element by means of adhesive with simultaneous electrical connection between the receiving chip and carrier element, a relatively large amount of space is saved, since the wiring and the housing are omitted. On the other hand, the receiving chip is relatively well protected against contamination, since it is relatively difficult for contamination to get between the adhesive layer and the receiving chip.
In weiterer Ausgestaltung der Erfindung ist auf der dem Haftmittel gegenüberliegenden Seite des Trägerelements ein optisches Linsensystem angeordnet, das mit dem Trägerelement verbunden ist. Somit kann die Genauigkeit der optischen Abbildung erheblich gesteigert werden. Zusätzlich kann das Trägerelement selber auch als optisches Linsenelement ausgebildet sein.In a further embodiment of the invention, an optical lens system, which is connected to the carrier element, is arranged on the side of the carrier element opposite the adhesive. The accuracy of the optical imaging can thus be increased considerably. In addition, the carrier element itself can also be designed as an optical lens element.
