Abstract
Die Erfindung betrifft ein Verfahren zur Herstellung verpackter Bauelemente. Dazu werden auf einem plattenförmigen Abdecksubstrat (1) rahmenförmige Strukturen (15) mit einer Lücke (17) hergestellt. Das Abdecksubstrat (1) wird auf einem Trägersubstrat (18) befestigt und durchtrennt, so dass ein Verbundteil mit dem Trägersubstrat (18) und einzelnen durch die Gräben (20) voneinander getrennten, aber über das Trägersubstrat (18) miteinander verbundenen Abdeckteilen (21) erhalten wird. Das Verbundteil wird mit den rahmenförmigen Strukturen (15) mit einem Funktionssubstrat (30) verbunden, so dass Kavitäten (40) definiert werden, welche Funktionsbereiche (34) des Funktionssubstrats (30) umschließen. Durch die Lücken (17) in den rahmenförmigen Strukturen wird ein Gasaustausch der Kavität mit der Umgebung erreicht, der weitere Verarbeitungsschritte im Vakuum ermöglicht.
