  • Publication number: 20240321949
    Abstract: A semiconductor device (1) is provided and a method of manufacturing the same. The method comprising providing a substrate (2) having formed thereon or therein a main junction (3). The method further comprises forming a junction termination structure (5) comprising a plurality of junction termination paths (8b-8g), wherein each path comprises an implanted region (9b-9g) having an implanted width. The step of forming a junction termination structure further comprises determining an individual width for each implanted width and a single first dopant dose which corresponds to an individual effective sheet charge concentration for each path such that, when said semiconductor device is in use, a desired electric field distribution over the second region of the semiconductor device is achieved. The step of forming a junction termination structure further comprises doping the implanted regions, each having the individual width, with dopants according to said first single dopant dose.

  • Patent number: 11349183
    Abstract: A waveguide switch for switching between an ON-state and an OFF-state for a waveguide channel, including: a moveable waveguide switch body including: an input opening for receiving an electromagnetic wave, an output opening for releasing an electromagnetic wave, wherein the waveguide switch body further includes a blocking element arranged such that in the ON state, an electromagnetic wave may pass from the input opening to the output opening, and in the OFF state the blocking element substantially impedes an electromagnetic wave traveling from the input opening to the output opening, whereby the switch from the ON state to the OFF state is a rotational or translation movement of the waveguide switch body. Also, a waveguide system employing such a switch and a method of manufacturing such a switch. Contactless switching is provided in a high-frequency system.
