Abstract:
1. An X-ray imaging device having a plurality of full-frame transfer type CCD chips aligned in a horizontal direction and being arranged adjacent to each other, wherein each of said CCD chips comprises: an imaging region formed of a plurality of vertical shift registers to be driven by means of TDI; a horizontal shift register which transfers a charge that has been transferred from said imaging region along said horizontal direction; a horizontal charge compressing vertical shift register row which is continued to a charge transfer direction terminal of said imaging region, has the same pixel number along said horizontal direction as that of the imaging region, has a length at the side of said horizontal shift register being shorter than that of the imaging region, and transfers a charge that has flown-in from the charge transfer direction terminal of said imaging region to said horizontal shift register; an amplifier positioned near the charge transfer direction terminal of said horizontal shift register and connected to this terminal, said amplifier being arranged in a region between this terminal and a horizontal shift resistor of a neighboring CCD chip; a light shield film provided on said horizontal charge compressing vertical shift register row; and a plurality of bonding pads disposed outside the vertical ends of said imaging region, connected to said amplifier and transfer electrodes formed on said imaging region.
