Information Management System: The potential in a charge-coupled device with no mobile minority carriers

Abstract

The potentials and fields in a two-dimensional model of a charge-coupled device (CCD) are studied. We assume no mobile minority carriers have been injected into the CCD and that the electrode voltages do not vary with time. The nonlinear equations describing the devices are first linearized using the depletion layer approximation. The linearized equations are then solved approximately by a fitting technique. Both surface and buried channel CCD's are considered. The accuracy and cost of obtaining the solution is discussed. This work is a continuation of a study initiated in an earlier paper.1
