    摘要: A thin film semiconductor device and a method for producing it are described. In the thin film layer of semiconductor of the device, a plurality of large size single-crystalline grains of semiconductor are formed in a regulated configuration, and each of single crystalline grains is equipped with one unit of electric circuit having a gate electrode, a source electrode and drain electrode. Such regulated arrangement of large size single-crystalline grains in the semiconductor layer is realized by a process including a step of irradiating the layer of amorphous or polycrystalline semiconductor with energy beam such as excimer laser so that maximum irradiation intensity points and minimum irradiation intensity points are arranged regulatedly. The device can have a high mobility such as about 500 cm /V sec.

    摘要: According to the semiconductor thin-film and semiconductor device manufacturing method of the present invention, an insulating film having a through-hole between two layers of silicon film is provided, the silicon film is partially melted by irradiating a laser thereon, and a substantially monocrystalline film is continuously formed extending via the through-hole from at least part of the layer of silicon film below the insulating film that continues to the through-hole, to at least part of the layer of silicon film above the insulating film. It is therefore sufficient to form a through-hole with a larger diameter than that of a hole formed by the conventional method, because the diameter of the through-hole in the insulating film may be the same size or slightly smaller than the size of a single crystal grain that comprises the polycrystal formed in the silicon film below the insulating film. Costly precision exposure devices and etching devices are therefore unnecessary. Numerous high-performance semiconductor devices can also be formed easily on a large glass substrate, as in large liquid-crystal displays and the like.

    摘要: There is suggested a method for forming a good-quality polysilicon layer having a large area through a low temperature process even if laser annealing is not conducted. An object of the present invention is therefore to provide a poly-Si TFT array substrate exhibiting little display unevenness and having a high exactitude even if it has a large screen. This object can be attained by a method for producing a TFT array substrate for a liquid crystal display device, comprising a process of forming, on a substrate, a poly-Si TFT in which a polysilicon semiconductor layer is used in a channel area, comprising a polysilicon layer forming step of depositing silicon particles excited by adding energy beforehand onto the substrate so that the polysilicon layer is formed at the stage when the silicon particles are deposited on the substrate.

    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.
