Amorphous silicon thin film transistor image sensors

 

Amorphous silicon thin film transistors (TFT) are the underlying technology for flat panel displays and medical X-ray imaging. We describe some recent developments in TFT technology for high performance detectors and flexible image sensors. X-ray detectors with high gain now make it possible to detect the ionization tracks of individual X-rays and provide a new approach to neutron imaging. Development of the amorphous silicon deposition process makes it possible to fabricate image sensor arrays on plastic substrates.
