  • Patent number: 7924392
    Abstract: An active matrix liquid crystal display having improved reliability. Pixel regions and a peripheral driver circuit are integrally packed on the display. TFTs forming the peripheral driver circuit are located inside a sealing material layer on the side of a liquid crystal material, thus protecting the peripheral driver circuit from external moisture and contaminants. This enhances the long-term reliability of the peripheral driver circuit. Pixel TFTs are arranged in pixel regions. The leads going from the TFTs forming the peripheral driver circuit to the pixel TFTs are shortened. This results in a reduction in the resistance. As a result, the display characteristics are improved.

  • Patent number: 7863618
    Abstract: The present invention provides an active matrix type display device having a high aperture ratio and a required auxiliary capacitor. A source line and a gate line are overlapped with part of a pixel electrode. This overlapped region functions to be a black matrix. Further, an electrode pattern made of the same material as the pixel electrode is disposed to form the auxiliary capacitor by utilizing the pixel electrode. It allows a required value of auxiliary capacitor to be obtained without dropping the aperture ratio. Also, it allows the electrode pattern to function as a electrically shielding film for suppressing the cross-talk between the source and gate lines and the pixel electrode.

  • Patent number: 7837792
    Abstract: In a method for manufacturing a crystalline silicon film by utilizing a metal element that accelerates the crystallization of silicon, an adverse influence of this metal element can be suppressed. A semiconductor device manufacturing method is comprised of the steps of: forming an amorphous silicon film on a substrate having an insulating surface; patterning the amorphous silicon film to form a predetermined pattern; holding a metal element that accelerates the crystallization of silicon in such a manner that the metal element is brought into contact with the amorphous silicon film; performing a heating process to crystalize the amorphous silicon film, thereby being converted into a crystalline silicon film; and etching a peripheral portion of the pattern of the crystalline silicon film.

  • Patent number: 7838968
    Abstract: There are disclosed TFTs having improved reliability. An interlayer dielectric film forming the TFTs is made of a silicon nitride film. Other interlayer dielectric films are also made of silicon nitride. The stresses inside the silicon nitride films forming these interlayer dielectric films are set between ?5×109 and 5×109 dyn/cm2. This can suppress peeling of the interlayer dielectric films and difficulties in forming contact holes. Furthermore, release of hydrogen from the active layer can be suppressed. In this way, highly reliable TFTs can be obtained.

  • Publication number: 20100289969
    Abstract: An image display system comprises a first liquid crystal projector which projects a counterclockwise-rotating, circularly polarized light beam to form an image containing specific visual information on a screen and a second liquid crystal projector which projects a clockwise-rotating, circularly polarized light beam to form a white image on the same screen. When viewed with the naked eye, a combination of the two images projected on the screen appears totally white. A viewer wearing a dedicated viewing device equipped with an optical filter which allows counterclockwise-rotating, circularly polarized light to pass through can selectively see the image projected by the first liquid crystal projector.

  • Patent number: 7723788
    Abstract: A thin film transistor device reduced substantially in resistance between the source and the drain by incorporating a silicide film, which is fabricated by a process comprising forming a gate insulator film and a gate contact on a silicon substrate, anodically oxidizing the gate contact, covering an exposed surface of the silicon semiconductor with a metal, and irradiating an intense light such as a laser beam to the metal film either from the upper side or from an insulator substrate side to allow the metal coating to react with silicon to obtain a silicide film. The metal silicide layer may be obtained otherwise by tightly adhering a metal coating to the exposed source and drain regions using an insulator formed into an approximately triangular shape, preferably 1 ?m or less in width, and allowing the metal to react with silicon.

  • Patent number: 7709837
    Abstract: Nickel is selectively held in contact with a particular region of an amorphous silicon film. Crystal growth parallel with a substrate is effected by performing a heat treatment. A thermal oxidation film is formed on the silicon film by performing a heat treatment in an oxidizing atmosphere containing a halogen element. During this step, in the silicon film, impurities included such as oxygen or chlorine, are segregated with extending along the crystal growth, the crystallinity is improved, and the gettering of nickel element proceeds. A thin-film transistor is formed so that the direction connecting source and drain regions coincides with the above crystal growth direction. As a result, a TFT having superior characteristics such as a mobility larger than 200 cm2/Vs and an S value smaller than 100 mV/dec. can be obtained.
