Flexible Image Sensor Array Using IGZO TFT Backplane Technology for X-ray Detector

42‐4: Late‐News Paper: A Radiation‐Hardened Oxide TFT with a Multi‐Layered Gate Dielectric

“…X-ray flat-panel detectors (FPDs) comprising a-Si thin-film transistors (TFTs) and a-Si pin photodiodes are highly effective sensor devices used in the field of medical imaging and nondestructive inspection. Extensive research has been conducted on the development of FPDs with oxide TFTs because they can achieve higher frame rates than a-Si TFTs [1][2][3]. However, oxide TFTs have a lower radiation hardness than a-Si TFTs [4][5][6].…”
