  • Patent number: 11367795
    Abstract: A semiconductor device including a first substrate and a thin film transistor disposed on the first substrate is provided. The thin film transistor includes a gate, a semiconductor pattern, a first insulating layer, a source and a drain. The first insulating layer is disposed between the gate and the semiconductor pattern. The source and the drain are separated from each other and disposed corresponding to the semiconductor pattern. At least one of the source and the drain has a first copper patterned layer and a first copper oxynitride patterned layer. The first copper oxynitride patterned layer covers the first copper patterned layer. The first copper patterned layer is disposed between the first copper oxynitride patterned layer and the first substrate. Moreover, a manufacturing method of the semiconductor device is also provided.

  • Patent number: 9905701
    Abstract: An active device structure and a method of fabricating an active device are provided. The active device structure includes a gate, an oxide channel layer, a source, a drain and a high power deposited insulation layer. The gate and the oxide channel layer are overlapped in a top and bottom manner. The oxide channel layer includes a top layer and a bottom layer having a crystalline structure different from a crystalline structure of the top layer. The source and the drain both contact the oxide channel layer, wherein a gap separating the source and the drain defines a channel area. The high power deposited insulation layer contacts the top layer of the oxide channel layer. The top layer of the oxide channel layer provides the effect of blocking light, which solves the problem of threshold voltage shift due to the light irradiation on the oxide channel layer.
