Abstract :
In this paper, we discuss various design and technological issues related to the process integration of a Mo/a-Si:H Schottky diode and a thin film transistor (TFT) to fabricate an X-ray imaging pixel. The Schottky diode is intended as an X-ray detector whereas the TFT serves as a switching element for charge readout. We compare two geometrically different pixel structures considering design aspects such as fill factor and leakage current
