  • Patent number: 11975296
    Abstract: A pore-filled ion exchange polyelectrolyte composite membrane from which the surface ion exchange polyelectrolyte has been removed and a method of manufacturing the same are provided. The ion exchange polyelectrolyte composite membrane exhibits low film resistance and low in-plane-direction swelling degree, and has a smaller film-thickness than a commercial film, and thus, can be used for various purposes. In addition, since the pore-filled ion exchange polyelectrolyte composite membrane is continuously manufactured through a roll-to-roll process, the manufacturing process is simple, and manufacturing costs can be greatly reduced.

  • Publication number: 20240113188
    Abstract: An integrated circuit (IC) structure includes a semiconductor substrate, a first gate line, a second gate line, and a first auxiliary gate portion. The semiconductor substrate comprises a semiconductor fin. The semiconductor fin extends substantially along a first direction. The first gate line and the second gate line extend substantially along a second direction different form the first direction from a top view. The first auxiliary gate portion connects the first gate line to the second gate line from the top view.

  • Publication number: 20240098880
    Abstract: The present disclosure relates to an electronic device, and more specifically, to an electronic device including a printed circuit board including a heat-generating element arranged on one surface thereof, and a heat transfer coin provided such that one surface of the heat transfer coin comes into contact with a portion of the other surface of the printed circuit board, opposite to the heat-generating element, so as to dissipate heat generated from the heat-generating element. Accordingly, the present disclosure provides an advantage of improving heat dissipation performance without increasing the thickness of the printed circuit board.
