Abstract: In the case of a process for the production of a layered structure for vertical magnetic data storage, first of all a soft-magnetic layer (2) and then a carrier layer (3) of non-magnetic material are applied to a substrate (1). A multiplicity of discrete core tracks are made in the carrier layer (3) by bombardment with high-energy heavy ions. The core tracks are converted by etching into corresponding channels. Finally, the channels are filled with magnetic material, so that a microneedle structure comprising a multiplicity of needles (4) of magnetic material, arranged perpendicularly to the substrate surface, is produced, i.e. a magnetic form anisotropy perpendicular to the plane of the layers results.

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.

Abstract: The invention relates to a magnetic disk of increased wear resistance and to a process for its production. The magnetic disk (1) comprises a non-magnetic substrate (3) and a magnetic thin film (4) arranged thereupon. Enhanced regions (6) in the form of concentric rings are introduced into the magnetic thin film (4) by local, maskless high-current ion implantation. By a correspondingly adapted dose rate and by introducing the dose in surges per unit area in extremely short times, there forms in the region of the rings (6) a eutectic mixture, the melting temperature of which is rapidly exceeded, which cools rapidly as a consequence of the great temperature gradient and results in the formation of a metal glass. The concentric rings of the metal glass accomplish an adequate level of wear resistance of the surface of the magnetic thin film, so that no coating is required. Because the metal glass is non-magnetic or soft-magnetic, the rings can at the same time bear the servo information for the magnetic disk.

Abstract: The proposal is the use of the prior art C4 technique to produce an electrical connection between an IC unit (2) and a substrate component (4) designed for inclusion in chip cards or other data medium boards. This results in facilities for contact between the IC unit (2) and the substrate component (4) permitting a high degree of integration of the IC unit (2) and a correspondingly large number of contacts between the IC unit (2) and its environment, makes contact possible over the entire surface of the IC unit (2) and, for the same requirements for contact between the IC unit (2) and the substrate (4), lower structural heights of the connection between said IC unit (2) and the substrate (4).

Abstract: In order to generate large-area, periodic patterns, the substrates (9) covered with a photosensitive layer are brought into the interference field (8) which is produced by four plane, mutually inclined waves. The plane waves are produced by splitting a laser beam (1) in a holographic lattice grating (2) which directs the total incident light energy into the four first diffraction orders. In order to collimate the diffraction beam, use is preferably made of large-area mirror optical systems by means of which the angle of inclination of the plane waves with respect to one another can be varied. It is possible to produce with the aid of the photolithographic device magnetic surface memories having vertical, insular magnetisation domains, or other surfaces which are covered with closely packed, vertical needles.
