  • 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: 20110032356
    Abstract: A recording device for a moving vehicle includes an image receiving unit, a speed calculating unit, a time unit, a positioning unit and a storing unit. The recording device records outside images when the vehicle moves via a camera lens of the image receiving unit. The speed calculating unit calculates speed using a speed gauge linked to the vehicle. Users can adjust time according to their demand by utilizing a time calculating function built in the time unit. Coordinates of vehicle location are obtained by a positioning unit linked to a satellite. The data mentioned above is stored in the storing unit. The device is installed inside the vehicle before the vehicle is factory assembled. When users start the vehicle, the recording device starts recording. When users turn off the vehicle and leave, the recording device can be re-started by using a switch. The image receiving unit keeps recording images.
