Abstract: Sensitive component structures (2) can be encapsulated by enclosing them wit h a frame structure (6) consisting of a light-sensitive reaction resin and covering the latter with another, structured layer of reaction resin after applying an auxiliary film (7). Top structures (10) which fit over the frame structures (6) can be produced e.g., by structured imprinting or photostructuring. The residual parts of the exposed auxiliary film are remov ed by dissolving or etching.

Abstract: Producing a hermetic encapsulation comprises fixing and electrically contacting a component formed on chip (1) on a support (4) having electrical connecting surfaces (7) so the component structures direct the front side of the chip to the support; covering the rear side of the chip with a plastic film (8) so the edges of the film overlap the chip; connecting the film with the support in the whole edge region around the chip in a sealed way; structuring the film so that it is partially removed outside of the edge region; and applying a hermetically sealed layer (14) over the film. The sealing layer hermetically seals with the support in a contact region outside of the edge region. Preferred Features: The film is a thermoplastic film which overlaps the chip and is laminated on the chip rear side and the support under pressure and elevated temperature. A base metallization is applied on the film and the surrounding surface of the support.
