ABSTRACT:
A solid state radiation imager that exhibits reduced capacitive coupling between pixel photodiodes and readout data lines, and thus further has reduced phantom images or image artifacts, includes a plurality of shield lines disposed at the same level of the device as the scan lines and associated gate electrodes for the switching transistors. The shield lines include respective pixel shielding spurs oriented along the same axis as the data lines and disposed between portions of the pixel photodiode and adjacent portions of the data lines. The shield lines are typically coupled to a shield voltage source such that the shield lines are maintained at a common potential.
