  • Patent number: 9143710
    Abstract: The present invention relates to a sensor-integrated chip for a CCD camera in which a CCD sensor, an H/V driver for driving the CCD sensor, and an ISP (Image Signal Process) chip, which inputs a control signal for driving the CCD sensor to the H/V driver and allows a video to be displayed on a monitor (not shown) in response to an output signal from the CCD sensor, are stacked and connected with each other by inter-pad wire bonding into one IC package to be one chip, by an SIP (system In Package) method.
