Title: Ching-Chieh Shih: Innovator in Thin Film Transistor Technology

Introduction

Ching-Chieh Shih is a prominent inventor based in Kinmen County, Taiwan. He has made significant contributions to the field of thin film transistor (TFT) technology, holding a total of 7 patents. His work focuses on innovative methods for fabricating TFT array substrates, which are essential components in display technologies.

Latest Patents

One of his latest patents is titled "Thin film transistor array substrate and method for fabricating the same." This patent outlines a method for creating a TFT array substrate that includes several steps. The process begins with providing a substrate that has both a pixel region and a photosensitive region. A first patterned conductive layer is then formed on the substrate, which includes a gate electrode in the pixel region and a first electrode in the photosensitive region. Following this, a photosensitive dielectric layer is applied over the first electrode, and a gate insulation layer is formed to cover the gate electrode, the photosensitive dielectric layer, and the first electrode. A patterned semiconductor layer is then created above the gate electrode, followed by the formation of source and drain electrodes on either side of the gate electrode, completing the TFT structure. Additionally, a second electrode is formed on the photosensitive dielectric layer.

Another notable patent is for an "Active device array substrate." This invention provides a substrate with a display area and a sensing area. The process involves placing a first patterned conductor layer on the display area, followed by a gate insulator on the substrate. A patterned semiconductor layer, a second patterned conductor layer, and a patterned photosensitive dielectric layer are then added. The second patterned conductor layer includes source and drain electrodes, while the patterned photosensitive dielectric layer features an interface protection layer and a photo-sensing layer. Finally, a passivation layer is applied, and a third patterned conductor layer, which includes a pixel electrode and an upper electrode, is disposed on the passivation layer.
