  • COLOR IMAGE SENSOR DEVICE AND FABRICATION METHOD THEREOF
    Publication number: 20080057614
    Abstract: A color image sensor device and fabrication method thereof. A passivation layer and a first planarization layer are sequentially formed on a substrate. A plurality of color filter elements are disposed over the first planarization layer corresponding to the sensor pixel array. A second planarization layer and a third planarization layer are sequentially formed over the first planarization layer. The third planarization layer has an opening formed corresponding to a contact pad. A third opening in the first planarization layer and the passivation layer corresponds to the contact pad.
    Type: Application
