Abstract:
1. An image sensor comprising: a first substrate having a CCD array fabricated thereon in a first fabrication system, said CCD array comprising a plurality of pixels that accumulate charge when exposed to light and a node through which charge from each of said pixels passes during a readout operation; a first FET fabricated on said first substrate in said first fabrication system, said first FET having a gate connected to said node and a source or drain connected to a first conducting pad on said first substrate; a first capacitor connecting said node to a second conducting pad on said first substrate; and a first switch fabricated on said first substrate in said first fabrication system, said first switch being connected across said first capacitor such that said first capacitor is shorted when said first switch is closed, said first switch being controlled by a reset signal on a third conducting pad on said first substrate.
