Carrier Diffusion Degradation of CCD (Charge-Coupled Devices) Imager MTF (Modulation Transfer Function) for Broadband Optical Sources

Abstract

Analytical results for the degradation of charge-coupled-imager modulation transfer function due to minority carrier diffusion effects are given for broadband optical sources. Both frontside and backside illuminated devices are considered. The effect of restricting the optical band on both broadband modulation transfer function and responsivity is considered. It is concluded that best imager performance is obtained for the full optical band (0.4-1.2 micrometers), and that backside illumination is the best approach to device fabrication from the standpoint of carrier diffusion degradation of modulation transfer function.
