Abstract: The disclosure relates to an electrical contact structure, and corresponding method of manufacturing an electrical contact structure, for a discrete semiconductor device. The electrical contact includes a first metal layer configured and arranged to contact a strained active area of a semiconductor die, a second metal layer configured and arranged to contact the first metal layer, and a third metal layer configured and arranged to contact the second metal layer.

Abstract: The invention relates to an ignition device (1) for an internal combustion engine, more particularly for a hydrogen-fueled internal combustion engine, comprising a primary circuit (2.1) and a secondary circuit (2.2), wherein—the primary circuit (2.1) has a primary coil (3), wherein—the secondary circuit (2.2) has a secondary coil (4) inductively coupled to the primary coil (3), a diode (5) for suppressing a start-up spark, and a high-voltage connector (6) for connection to a spark plug (7), characterized in that a parallel path (10) is formed electrically in parallel to the diode (5) of the secondary circuit (2.2), in which parallel path there is arranged an ohmic load resistor (11) or an electric switch (20) and by means of which parallel path residual energy, in particular residual voltage, which remains in the secondary circuit (2.2) following discharge of the ignition device (1), can be extinguished, in particular by feeding the residual energy in the secondary circuit (2.

Abstract: An apparatus for producing a three-dimensional object by hardening a photocuring material includes a radiation source unit having a radiation source for emitting light, a receiving device having a receiving surface for receiving the photocuring material in liquid form, a carrier plate for receiving the photocuring material in a cured form, said carrier plate being movable relative to the receiving device, and a deflection device for deflecting the light emerging from the radiation source onto the carrier plate. The deflection device has at least one totally reflecting optical element, wherein the light emerging from the radiation source unit is totally reflected at least twice overall by the at least one optical element. A compact configuration of the apparatus can be achieved as a result.
