Abstract:
The invention relates to a semiconductor chip having a protective layer (6,8) made of an abrasion-resistant and/or etch-resistant material applied thereto. The material can, for example, contain abrasion-resistant grains. In a preferred embodiment, the thickness of the semiconductor body (1) is reduced to less than 50 mu m. As a result, the chip inevitably breaks if an attempt is made to grind the hard protective layer. The wafer is pre-cut from the front side so that the chips can be individually separated in an easier manner, be provided with said protective layer (6), the thickness thereof being subsequently reduced from the rear side.
Abstract:
According to the invention, a biometric sensor, e.g. a fingerprint sensor FiTiKey, is combined with a standardized medium. The standard of the MultiMediaCard (1) with the corresponding reading devices and with the standardized slots is a preferred embodiment, which consists of the combination of this existing standard for storage applications (MultiMediaCard with the corresponding system peripheral equipment) with the personal, mobile authentication and/or identification key FiTiKey (2) and, optionally, with additional chips (3).
Abstract:
The invention relates to a non-conductive substrate (2) forming a band or panel on which are embodied a plurality of support elements, notably for incorporation into a chip card. One side of the substrate (2) has conductive contact surfaces (6) which lie within an outer contour line (4) that determines the size of one support element. The other side of the substrate (2) has conductive structures (9, 10, 11, 14, 15) which, within the outer contour line (4), form at least contact areas (11) for at least one coil to be contacted and at least one semi-conductor chip. Outside each outer contour line (4) the invention provides for recesses (13) in the substrate (2), through which the connections to the coil of the semi-conductor chip can be accessed for test purposes from the side of the contact surface as long as the support element remains in the band or panel.
Abstract:
Disclosed is a chip module, especially for implantation in the body of a chip card (25) comprising a carrier (10) and a chip (13) placed thereon. Disclosed chip module is characterized by base-type elevation (23) which encompasses chip either entirely or partially.
Abstract:
A carrier element for a semiconductor chip (23), in particular for mounting in chip cards, has a substrate (15) that carries the chip (23) and a reinforcing foil (10) laminated on the side of the substrate (15) that carries the chip (23). The reinforcing foil (10) has a recess (14) for receiving the chip (23) and its connection lines (24), whose edge is provided with a frame (12) that forms a single piece with the foil (10).
Abstract:
Die Erfindung schlägt einen Träger (10) mit einer Kavität (11) vor, in die ein weiterer Träger (20) derart einsetzbar ist, daß dieser mit einer Oberseite (13) des Trägers (10) in etwa bündig abschließt und zwischen einer Wandung (12) der Kavität (11) und dem weiteren Träger (20) im belastungsfreien Zustand keine Spalte aufweist. Erfindungsgemäß ist vorgesehen, daß der weitere Träger (20) über zumindest ein Ausgleichselement (23) verfügt, durch welches bei einer Biegung des Trägers (10) eine Belastung des weiteren Trägers (20) vermieden wird.
Abstract:
This invention concerns a substrate element for a semiconductor chip for incorporation into chip cards as well as for soldering onto boards using SMD technology. For this purpose, the copper cladding of a plastic film (1) is so structured using etching, that contact surfaces (3) are formed in one piece with conductor paths (4) which end at the border of the substrate element and which make reliable soldering possible.
Abstract:
Described is a chip-card blank (1) with a recess (10) designed to hold a chip module (30). The card blank described is characterized in that it has, inside the recess, a restraining device which entirely or partly surrounds the central zone of the recess and prevents adhesive from spreading into the central zone. 00000
Abstract:
The description relates to a chip cover (6) to cover completely or partially electrical, electronic, opto-electronic and/or electromechanical components of a chip (1, 8). The chip cover (6) is characterized in that is has a polyimide coating with limited transparency. It is thus possible reliably to prevent unauthorised examinations and/or manipulations of the chip.
Abstract:
The description relates to a chip cover (5, 6, 11) to cover electrical, electronic, opto-electronic and/or electromechanical components of a chip (1, 8) completely or partly. In the chip cover (5, 6, 11), there is an activator (12) which, when activated, is capable of completely or partly destroying the electrical, electronic, opto-electronic and/or electromechanical components of the chip (1, 8) and can be activated by an attempt to remove the cover (5, 6, 11) from the chip (1, 8). It is thus possible reliably to prevent the unauthorised analysis and/or manipulation of the chip (1, 8).
