  • Patent number: 8008654
    Abstract: A method of manufacturing a thin-film transistor device improves performance of a complementary TFT circuit incorporated in a thin- and light-weighted image display device or a flexible electronic device, and reduces power consumption manufacturing cost. Electrodes forming n-type and p-type TFTs and an organic semiconductor are made of the same material in both types of TFT by a solution-process and/or printable process method. A first polarizable thin-film is formed on an interface between a gate insulator and a semiconductor, and a second polarizable thin film provided on an interface between source and drain electrodes and the semiconductor film. A complementary thin-film transistor device is manufactured by selectively exposing either the n-type TFT area or the p-type TFT area to light to remove the polarizing function from the first and second polarizable thin films.

  • Patent number: 7989143
    Abstract: An electrode substrate in which a lower electrode and an upper electrode are well positioned by way of an insulating film could not be formed by a printing method since positional displacement is caused. The cost was increased outstandingly when using photomasks for positioning. In the present invention, positional displacement does not occur even when using the printing method since the upper electrode and the lower electrode are positioned in self-alignment. Accordingly, a semiconductor device such as a flexible substrate using an organic semiconductor can be formed with low cost by using the printing method.

  • Patent number: 7907797
    Abstract: This invention provides an efficient image processing apparatus having merits as the handiness and visibility of paper and the multi-functionality of a computer, enabling trial and error with paper media without capturing all images previously. The apparatus comprises an image capturing unit for electronically capturing paper images by a photo-sensor; an image editing unit for editing such as clipping of partial image or scaling; a user interface unit for receiving user's commands regarding the image editing; an image memory unit for storing; and an image display unit for displaying the images in the image memory unit. An image displaying function is provided on a transparent plane. Photo-sensors are on the plane, and image capturing unit and image display unit are integrated to form an image capturing and display unit. A user gains an operability compatible with human instinct, ignoring a difference between paper and electronic medium.

  • Patent number: 7872257
    Abstract: An n-type TFT and a p-type TFT are realized by selectively changing only a cover coat without changing a TFT material using an equation for applying the magnitude of a difference in the Fermi energy between an interface of semiconductor and an electrode and between an interface of semiconductor and insulator. At this time, in order to configure a predetermined circuit, the process is performed, as a source electrode and a drain electrode of the p-type TFT and a source electrode and a drain electrode of the n-type TFT being connected all, respectively, and an unnecessary interconnection is cut by irradiating light using a scanning laser exposure apparatus or the like.
