Design, fabrication, operation and performance are described for a 360/spl times/360 element very high frame rate (VHFR) image sensor that can capture images at a frame rate of up to 10/sup 6/ frames/s. This VHFR imager has 50/spl times/50 /spl mu/m macropixels, each consisting of a high-speed zero-lag photodetector with a 13.5% fill factor and 30 stages of serial-parallel type buried-channel CCD registers for storage and readout of the last 30 image frames acquired. Readout of this imager is similar to a frame transfer CCD consisting of four quadrants. Each quadrant contains one million pixels, readout at a relatively slow rate compatible with low readout noise, and PC class microcomputer-based data acquisition and storage. This imager is designed using SiO/sub 2//Si/sub 3/N/sub 4/ gate dielectric, four levels of polysilicon, three levels of metal, eight implants, 21 photo masks using 1.5-/spl mu/m design rules, and it has four output ports. The high-speed photodetector is designed in the form of a graded three-potential-level pinned-buried BCCD structure. This 33-/spl mu/m long photodetector can achieve complete readout of photogenerated electrons in less than 0.1 /spl mu/s.
