Abstract
The design for two high fill-factor CCD arrays for optical signal processing applications is described. The imaging registers have 1024 x 1024 and 512 x 512 pixels and achieve virtually 100 percent optical fill factor through the use of substrate thinning and back illumination. High frame-rate readout is obtained by the use of a dual storage register and multiple floating-diffusion output ports resulting in reduced readout frequency. On-chip correlated double sampling amplifiers are implemented to reduce the readout noise and simplify off-chip analog signal processing. Both chips include antiblooming drain structures and ESD protection circuits.
