    Abstract: The ion generator includes a dielectric plate (1) comprising a number of electrodes (3) on one surface (1a), and covered with a structured conductive layer (2). A number of dielectric spacers (4) have respective second electrodes (5) on the side facing away from the dielectric plate. The spacers are connected to the first surface (1a) of the dielectric plate in such a way that cavities are formed by the first electrodes, parts of the first surface of the dielectric plate, and by the spacers with the second electrodes. The cavities accommodate the generated plasma. The ion generator is formed in a micromechanical process. The dielectric plate and the dielectric spacers are formed in a modular fashion and connected by adhesive points (7) or bonding points (7).

    Abstract: A process is disclosed for producing an IC-module that consists of a thin support element (4) upon which is mounted a semiconductor chip (2). This process also allows the use of IC-components (2) of especially large sizes (macrochips) and various types. The chip is injection moulded so that it has a minimum height without requiring further processing and may be economically surface-mounted. The module may be used both in flexible printed circuit cards (for example in photographic cameras) and in smart cards. In a first step of the process, at least one IC-component (2) is applied on the support element (4), in a second step the IC-component (2) is contacted with the support element (4) and in a third step an injection moulding material (18) is injection moulded around the IC-component (2) so as to envelop it.
