  • Publication number: 20010001562
    Abstract: An imaging device comprises a semiconductor substrate including an array of pixel cells. Each pixel cell comprising an individually addressable pixel circuit for accumulating charge resulting from radiation incident on a pixel detector. The pixel circuit and the pixel detector can either be implemented on a single substrate, or on two substrates bonded together. The charge storage device can be a transistor, for example one of a pair of FET transistors connected as a cascade amplification stage. An imaging plane can be made up of one imaging device or a plurality of imaging devices tiled to form a mosaic. The imaging devices may be configured as a slot for certain applications, the slit or slot being scanned over the imaging plane. Control electronics can include addressing logic for addressing individual pixel circuits for reading accumulated charge from the pixel circuits.
