  • Publication number: 20240113032
    Abstract: Interconnect structure packages (e.g., through silicon vias (TSV) packages, through interlayer via (TIV) packages) may be pre-manufactured as opposed to forming TIVs directly on a carrier substrate during a manufacturing process for a semiconductor die package at backend packaging facility. The interconnect structure packages may be placed onto a carrier substrate during manufacturing of a semiconductor device package, and a semiconductor die package may be placed on the carrier substrate adjacent to the interconnect structure packages.

    Abstract: An HOD device, comprising: a framework; covering material, covering the frame work; at least one conductive region, provided on or in the covering material; wherein the conductive region is coupled to a capacitance detection circuit or a predetermined voltage level. The HOD device can be a vehicle control device such as a steering wheel. The conductive region comprises conductive wires which can be threads of the covering material. By this way, the arrangements of the conductive wires can be changed corresponding to the size or the shape of the frame work or any other requirements. Also, the interference caused by unstable factors can be improved since the conductive wires can be coupled to a ground source of the vehicle to provide a short capacitance sensing path.
