Abstract:
Method for packaging a microelectronic device (100) in an hermetically sealed cavity (110) and managing an atmosphere of the cavity with a dedicated hole (130), comprising: - making said cavity between a support (102) and a cap layer (106) such that a sacrificial material and the device are arranged in the cavity; - removing the sacrificial material through at least one release hole (108), and hermetically sealing the release hole; - making a portion of wettable material (128) on the cap layer, around a blind hole or a part of said outside surface corresponding to a location of said dedicated hole; - making a portion of fuse material (126) on the portion of wettable material; - making the dedicated hole by etching the cap layer; - reflowing the portion of fuse material with a controlled atmosphere, forming a bump of fuse material (132) which hermetically plugs said dedicated hole.
Abstract:
Es wird ein miniaturisiertes Bauelement, das zur Verwendung mit verschiedenen Schaltungstechnologien kompatibel ist, angegeben. Das Bauelement umfasst einen Träger und eine funktionale Struktur auf dem Träger. Eine Dünnschicht- Abdeckung bedeckt die funktionale Struktur und dient als Montagebasis für eine Schaltungskomponente, die über der Dünnschicht-Abdeckung angeordnet ist. Die Schaltungskomponente ist über eine Zuleitung mit der funktionalen Struktur verschaltet.
