  • Patent number: 11936506
    Abstract: A system for transmitting a value via a pulse-width-modulated signal, comprises a transmitter and a receiver. The transmitter is configured for detecting the value and for outputting a pulse-width-modulated signal having a pulse width which represents the value or a range around the value. The receiver is configured for deriving the value or the range from the pulse-width-modulated signal, by evaluating the pulse width. The transmitter is furthermore configured to read back the emitted pulse-width-modulated signal and to check whether the value or the range can be derived from the emitted pulse-width-modulated signal, and, if the value or the range cannot be derived, to output an error signal to the receiver.

    Abstract: A semiconductor device includes a semiconductor body comprising a first surface and an edge surface, a contact electrode formed on the first surface and comprising an outer edge side, and a passivation layer section conformally covering the outer edge side of the contact electrode. The passivation layer section is a multi-layer stack comprising a first layer, a second layer, and a third layer. Each of the first, second and third layers include outer edge sides facing the edge surface and opposite facing inner edge sides. The outer edge side of the contact electrode is disposed laterally between the inner edge sides and the outer edge sides of each layer.

  • Patent number: 11721547
    Abstract: A method for manufacturing a silicon carbide substrate for an electrical silicon carbide device includes providing a silicon carbide dispenser wafer including a silicon face and a carbon face and depositing a silicon carbide epitaxial layer on the silicon face. Further, the method includes implanting ions with a predefined energy characteristic forming an implant zone within the epitaxial layer, so that the ions are implanted with an average depth within the epitaxial layer corresponding to a designated thickness of an epitaxial layer of the silicon carbide substrate to be manufactured. Furthermore, the method comprises bonding an acceptor wafer onto the epitaxial layer so that the epitaxial layer is arranged between the dispenser wafer and the acceptor wafer. Further, the epitaxial layer is split along the implant zone so that a silicon carbide substrate represented by the acceptor wafer with an epitaxial layer with the designated thickness is obtained.

  • Publication number: 20180237876
    Abstract: A method is used to produce a grain-oriented electrical steel strip having optimized magnetic properties. The method may utilize a steel comprising in percent by weight 2.0-4.0% Si, 0.010-0.100% C, at most 0.065% Al, at most 0.02% N, and optionally further constituents, the balance being iron and unavoidable impurities. The steel may be processed to give a cold strip, which may then be subjected to oxidation/primary recrystallization annealing. The resultant cold strip may have an oxide layer to which an annealing separator layer is applied. In a subsequent high-temperature anneal, a forsterite layer forms therefrom, and an insulation layer may be applied thereto prior to a final anneal.
