摘要： Electrical characteristics of transistors using an oxide semiconductor are greatly varied in a substrate, between substrates, and between lots, and the electrical characteristics are changed due to heat, bias, light, or the like in some cases. In view of the above, a semiconductor device using an oxide semiconductor with high reliability and small variation in electrical characteristics is manufactured. In a method for manufacturing a semiconductor device, hydrogen in a film and at an interface between films is removed in a transistor using an oxide semiconductor. In order to remove hydrogen at the interface between the films, the substrate is transferred under a vacuum between film formations. Further, as for a substrate having a surface exposed to the air, hydrogen on the surface of the substrate may be removed by heat treatment or plasma treatment.

摘要： In an active matrix semiconductor display device in which pixel TFTs and driver circuit TFT are formed on the same substrate in an integral manner, the cell gap is controlled by gap retaining members that are disposed between a pixel area and driver circuit areas. This makes it possible to provide a uniform cell thickness profile over the entire semiconductor display device. Further, since conventional grainy spacers are not used, stress is not imposed on the driver circuit TFTs when a TFT substrate and an opposed substrate are bonded together. This prevents the driver circuit TFTs from being damaged.

摘要： There is provided a thin film transistor having improved reliability. A gate electrode includes a first gate electrode having a taper portion and a second gate electrode with a width narrower than the first gate electrode. A semiconductor layer is doped with phosphorus of a low concentration through the first gate electrode. In the semiconductor layer, two kinds of n−-type impurity regions are formed between a channel formation region and n+-type impurity regions. Some of the n−-type impurity regions overlap with a gate electrode, and the other n−-type impurity regions do not overlap with the gate electrode. Since the two kinds of n−-type impurity regions are formed, an off current can be reduced, and deterioration of characteristics can be suppressed.
