  • Publication number: 20240107780
    Abstract: A system on chip (SoC) die package is attached to a redistribution structure of a semiconductor device package such that a top surface of the SoC die package is above a top surface of an adjacent memory die package. This may be achieved through the use of various attachment structures that increase the height of the SoC die package. After encapsulating the memory die package and the SoC die package in an encapsulation layer, the encapsulation layer is grinded down. The top surface of the SoC die package being above the top surface of the adjacent memory die package results in the top surface of the SoC die package being exposed through the encapsulation layer after the grinding operation. This enables heat to be dissipated through the top surface of the SoC die package.

  • Publication number: 20240071665
    Abstract: A wheel control mechanism includes a support base, a wheel module, a first magnetic module and a second magnetic module. The wheel module, the first magnetic module and the second magnetic module are installed on the support base. The first magnetic module generates a magnetic attractive force to attract a metal ratchet of the wheel module. By adjusting the position of the second magnetic module relative to the first magnetic module, the strength of the magnetic attractive force is changed. Consequently, the rotation of the wheel module results in a tactile feel or does not result in the tactile feel.
