Patent ID: 7145152

Claim:
An imager, comprising: a plurality of pixels disposed on a substrate in an imaging array pattern comprising rows and columns, each of the pixels comprising a respective photosensor coupled to a respective thin film switching transistor; a plurality of scan lines disposed at a first level with respect to the substrate along a first axis of the imaging array pattern, each row of pixels in the imaging array pattern having a respective scan line, each of the respective scan lines being coupled to a respective gate electrode in the thin film switching transistor for each pixel disposed along the respective row of pixels in the imaging array pattern; a plurality of data lines disposed at a second level with respect to the substrate along a second axis of the imaging array pattern, each column of pixels in the imaging array pattern having a corresponding data line, each of the respective data lines being coupled to a respective source electrode in the thin film switching transistors for each pixel disposed along the respective column of pixels in the imaging array pattern; wherein each pixel comprises a storage capacitor coupled parallel to the photosensor, the storage capacitor comprising a capacitor signal electrode and a capacitor common electrode and a dielectric disposed between the capacitor signal electrode and the capacitor common electrode.
