  • Patent number: 6734052
    Abstract: In a method of manufacturing a thin film transistor, in a first deposition step a light shield film is deposited on a substrate. In a second deposition step a semiconductor film is deposited for forming a channel of the transistor on the light shield film. In a patterning step the light shield film and the semiconductor film are simultaneously shaped into the same shape pattern. In an electrode forming step a source electrode and a drain electrode which are respectively in contact with both end-portions of the shaped semiconductor film are formed. An insulator film is formed so that the insulator film covers the source and drain electrodes and the semiconductor film. A gate electrode is formed at a location on the insulator film corresponding to the semiconductor film.
