  • Publication number: 20240113010
    Abstract: A semiconductor device is disclosed herein. The semiconductor device includes a routing structure. The routing structure has an intermediate conductive routing layer. The intermediate conductive routing layer includes a first mesh conductive layer formed in a predetermined second region of the semiconductor device and a second mesh conductive layer formed in a predetermined first region of the semiconductor device. The first mesh conductive layer and the second mesh conductive layer are electrically isolated from each other. The intermediate conductive routing layer further includes multiple first conductive islands formed in the predetermined first region and multiple second conductive islands formed in the predetermined second region.

  • Patent number: 11914429
    Abstract: An electronic device includes a host, a display, a sliding plate, and a keyboard. The host has an operating surface. The display is pivoted to the host. The sliding plate is slidably disposed in the host, where the display is mechanically coupled to the sliding plate, and the sliding plate includes a plat portion and a recess portion that are arranged side by side. The keyboard is integrated to the host. The keyboard includes a key structure, where the key structure includes a key cap and a reciprocating element, and the key cap is exposed from the operating surface of the host. The reciprocating element is disposed between the key cap and the sliding plate and has a first end connected to the key cap and a second end contacting the sliding plate. The second end is located on a sliding path of the plat portion and the recess portion.
