Abstract:
1. A method to produce a hermetic encapsulation for an electronic component, comprising: a) attaching and electrically contacting the electronic component based on a chip to a carrier comprising electrical connection surfaces by flip-chip technique, such that a front of the chip bearing component structures and solder connections for those component structures facing the carrier have a spacing between said front of the chip bearing said component structures and the carrier, said chip also having sides substantially perpendicular to the front and a back opposite the front and facing away from the carrier; b) covering of the back and sides of the chip with a film made of synthetic material, such that edges of the film overlap the chip; c) tightly bonding the film with the carrier in an entire edge region around the chip; d) structuring the film such that the film is removed around the edge region in a continuous strip parallel to the edge region and is also removed at a strip located at said sides of the chip to uncover a surface of the chip; and e) applying a hermetically sealing layer over the film, such that the sealing layer hermetically terminates with the carrier in a contact region outside of the edge region and also makes at least one of a sealing or shielding strip contact directly with the chip surface at the sides.
