  • Patent number: 6242292
    Abstract: In producing a semiconductor device by annealing with laser light irradiation, while a linear laser light is scanned in a direction perpendicular to a line, the annealing is performed for a semiconductor material. In this state, since an anneal effect in a beam lateral direction corresponding to a line direction is 2 times or more different than that in the scanning direction, a plurality of semiconductor elements are formed along a line direction in which the linear laser light is irradiated. Also, a line direction connecting the source and drain region of a thin film transistor is aligned to the line direction of the linear laser light.

  • Patent number: 6194254
    Abstract: A silicon film is crystallized in a predetermined direction by selectively adding a metal element having a catalytic action for crystallizing an amorphous silicon and annealing. In manufacturing TFT using the crystallized silicon film, TFT provided such that the crystallization direction is roughly parallel to a current-flow between a source and a drain, and TFT provided such that the crystallization direction is roughly vertical to a current-flow between a source and a drain are manufactured. Therefore, TFT capable of conducting a high speed operation and TFT having a low leak current are formed on the same substrate.

  • Patent number: 6166399
    Abstract: A method of fabricating silicon TFTs (thin-film transistors) is disclosed. The method comprises a crystallization step by laser irradiation effected after the completion of the device structure. First, amorphous silicon TFTs are fabricated. In each of the TFTs, the channel formation region, the source and drain regions are exposed to laser radiation illuminated from above or below the substrate. Then, the laser radiation is illuminated to crystallize and activate the channel formation region, and source and drain regions. After the completion of the device structure, various electrical characteristics of the TFTs are controlled. Also, the amorphous TFTs can be changed into polysilicon TFTs.

  • Patent number: 4919633
    Abstract: An improved liquid crystal device is described such as a display. The device comprises a pair of substrates, a liquid crystal layer, an electrode arrangement, and a ferroelectric film. The ferroelectric film is formed on the inside of the substrate by spinning method using a mixture of a ferroelectric material and an organic resin. When coating, the mixture is diluted with a solvent so that the ferroelectric film can be formed as a thin film. In advance of curring, the ferroelectric film is subjected to an electric field and its dipole moment is aligned and fixed in a direction perpendicular to the substrate. In virtue of the dipole moment, the liquid crystal device can be controlled by applying a voltage in one direction with a high stability.
