Abstract
A charge-coupled device for detecting spatial variation in the intensity of electromagnetic radiation comprises a body of semiconductor material that responds to electromagnetic radiation in a given spectral region by generating charge carriers. The body of semiconductor material has first and second sense volumes that are isolated from each other with respect to diffusion of charge carriers. A sense electrode structure overlies the sense volumes. First and second transfer regions are in communication with the first and second sense volumes respectively, and a transfer electrode structure overlies the transfer regions. A readout region has first and second zones in communication with the first and second transfer regions respectively and is connected to an output node. Charge can be accumulated in the sense volumes over an integration period and the resulting charge samples can be shifted separately through the transfer regions and applied to the output node.
