  • Patent number: 11551998
    Abstract: The present disclosure relates to a radio frequency device that includes a device region with a back-end-of-line (BEOL) portion and a front-end-of-line (FEOL) portion, first bump structures, a first mold compound, and a second mold compound. The FEOL portion includes an active layer, a contact layer, and isolation sections. Herein, the active layer and the isolation sections reside over the contact layer, and the active layer is surrounded by the isolation sections. The BEOL portion is formed underneath the FEOL portion, and the first bump structures and the first mold compound are formed underneath the BEOL portion. Each first bump structure is partially encapsulated by the first mold compound, and electrically coupled to the FEOL portion via connecting layers within the BEOL portion. The second mold compound resides over the active layer without a silicon material, which has a resistivity between 5 Ohm-cm and 30000 Ohm-cm, in between.

  • Publication number: 20220396943
    Abstract: An inverted plunger for unclogging pipes or toilets is described. The proposed inverted plunger does not have any openings filled with air, at the stretchable elastic bottom part, unlike all plungers described in the prior art. The proposed inverted plunger is equipped with the internal piston, that allows the pressure application to the narrower part of the stretchable bottom, leading to direct pressure from the stretched material to the liquid inside the pipe, avoiding the air-to-liquid pressure utilized in regular plungers. Using the electric motor in the proposed inverted plunger leads to the increased efficiency and to the easy use by the operator.
