Thin film transistor (TFT) and method of manufacturing thereof

摘要

There is provided a TFT having a trench surrounding gate structure that is capable of decreasing the leakage current generated during the Off-State of the TFT by securing enough channel length despite the smallness of the area, increasing the driving current by securing a sufficient cross-sectional area of an inverted channel during the On-State of the TFT, and improving the resolution of the LCD by reducing the space occupied by the TFT in the panel during the manufacturing of the LCD.
