  • Patent number: 8969868
    Abstract: A thin film transistor comprises a transparent substrate, a gate is disposed on the transparent substrate, a gate insulator is disposed on the gate and the transparent substrate, an active layer is disposed on the gate insulator, an electrode layer is electrically connected the active layer and the portion of the active layer is exposed, and an ultraviolet light absorbing layer is disposed on the electrode layer. By using the advantage of the ultraviolet light absorbing layer with the range of visible light transmittance and with the component protection, preventing the optical characteristics of the thin film transistor from the outside moisture is achieved, and by adjusting the parameters in the thin film deposition process to change its conductivity.

  • Publication number: 20140193964
    Abstract: The present invention provides a method of manufacturing a semiconductor device. The method at least comprises the following steps. First, the semiconductor device, which comprises a gate, a gate dielectric layer, an active layer, a source and a drain, is manufactured. However, the semiconductor device has a plurality of defects, and the active layer is a metal oxide thin film. After annealing the semiconductor device, it will be transferred into a chamber. A final step of injecting a supercritical fluid carried with a co-solvent into the chamber is then performed to modify the abovementioned defects.

  • Patent number: 8609460
    Abstract: A semiconductor structure and a fabricating method thereof are provided. The fabricating method includes forming a gate, a source, and a drain on a substrate and forming an oxide semiconductor material between the gate and the source and drain. The oxide semiconductor material is formed by performing a deposition process, and nitrogen gas is introduced before the deposition process is completely performed, so as to form oxide semiconductor nitride on the oxide semiconductor material.
