  • Patent number: 7508033
    Abstract: There is provided a highly reliable semiconductor device in which electrostatic breakdown can be prevented. A diamond-like carbon (DLC) film is formed on a surface of an insulating substrate, and thereafter, a thin film transistor is formed on the insulating substrate. This DLC film allows charges of static electricity to flow and can prevent electrostatic breakdown of the thin film transistor.

  • Patent number: 7507615
    Abstract: A method of manufacturing thin film field effect transistors is described. The channel region of the transistors is formed by depositing an amorphous semiconductor film in a first sputtering apparatus followed by thermal treatment for converting the amorphous phase to a polycrystalline phase. The gate insulating film is formed by depositing an oxide film in a second sputtering apparatus connected to the first apparatus through a gate valve. The sputtering for the deposition of the amorphous semiconductor film is carried out in an atmosphere comprising hydrogen in order to introduce hydrogen into the amorphous semiconductor film. On the other hand the gate insulating oxide film is deposited by sputtering in an atmosphere comprising oxygen.

  • Patent number: 7491659
    Abstract: In forming various types of insulating films in manufacture of a semiconductor device, carbon is gasified into CHx, COH etc. during film formation by adding active hydrogen and nitrogen oxide to reduce the carbon content during the film formation, and the effect of blocking impurities such as alkali metals is improved.

  • Patent number: 7465679
    Abstract: A silicon oxide film is formed to cover an island non-monocrystalline silicon region by plasma CVD using an organic silane having ethoxy groups (e.g., TEOS) and oxygen as raw materials, while hydrogen chloride or a chlorine-containing hydrocarbon (e.g., trichloroethylene) of a fluorine-containing gas is added to the plasma CVD atmosphere, preferably in an amount of from 0.01 to 1 mol % of the atmosphere so as to reduce the alkali elements from the silicon oxide film formed and to improve the reliability of the film. Prior to forming the silicon oxide film, the silicon region may be treated in a plasma atmosphere containing oxygen and hydrogen chloride or a chlorine-containing hydrocarbon. The silicon oxide film is obtained at low temperatures and this has high reliability usable as a gate-insulating film in a semiconductor device.

  • Patent number: 7038302
    Abstract: Improved method of heat-treating a glass substrate, especially where the substrate is thermally treated (such as formation of films, growth of films, and oxidation) around or above its strain point. If devices generating heat are formed on the substrate, it dissipates the heat well. An aluminum nitride film is formed on at least one surface of the substrate. This aluminum nitride film acts as a heat sink and prevents local concentration of heat produced by the devices such as TFTs formed on the glass substrate surface.

  • Patent number: 6812082
    Abstract: An interlayer insulating film (104) that is formed on a substrate (101) so as to cover TFTs (102, 103) is planarized by mechanical polishing that is typified by CMP. Pixel electrodes (106, 107) are formed on the interlayer insulating film (104) and an insulating layer (108) is formed so as to cover the pixel electrodes. The insulating layer (108) is planarized by second mechanical polishing so that the surfaces of the pixel electrodes become flush with those of resulting buried insulating layers (112, 113). Since the pixel electrode surfaces have no steps, such problems as alignment failures of a liquid crystal material and a contrast reduction due to diffused reflection of light can be prevented.
