Abstract

The invention discloses a thin film transistor array substrate, a manufacturing method thereof and a digital X-ray detector device. Provided are a thin film transistor array substrate for the digital X-ray detector device, the digital X-ray detector device, and a method of manufacturing the same, which are capable of minimizing the leakage current of a PIN diode. The leakage current blocking layer is formed to cover and contact a side surface of the PIN layer of the PIN diode to prevent contact between the PIN layer and the insulating layer, thereby minimizing the generation of leakage current of the PIN diode. Further, according to the present disclosure, the generation of leakage current of the PIN diode is minimized to increase detection power of the readout line, thereby improving the characteristics such as detection quantum efficiency (DQE) and signal-to-noise ratio (SNR), and improving the image quality of the digital X-ray detector apparatus.

Description

technical field [0001] The present disclosure relates to a thin film transistor array substrate for a digital X-ray detector device and a digital X-ray detector device capable of minimizing leakage current of a PIN (P-type semiconductor-intrinsic-type semiconductor-N-type semiconductor) diode, and fabrication thereof method. Background technique [0002] Because X-rays have short wavelengths, X-rays can easily pass through objects. The transmittance of X-rays depends on the internal density of the object. Therefore, the internal structure of the object can be observed by detecting the amount of X-rays transmitted through the object. [0003] One of the X-ray based inspection methods used in the medical field is the film printing scheme. However, in the film printing scheme, in order to check the result, an image is taken and then the film is printed. Therefore, it takes a long time to check the result. In particular, in the film printing scheme, there are some difficult...
