    摘要: A thin film transistor which can reduce production of leakage current between the source and drain electrodes and a fabricating method therefor, are disclosed. In the thin film transistor, an insulating film is formed on at least a portion of each side, corresponding to the region between the source and drain electrodes, of the peripheral side surface of the intrinsic semiconductor film, so that no metal silicide is formed thereon.

    摘要: A method of manufacturing a thin-film transistor which comprises the steps of forming a gate electrode on an insulating substrate, a gate insulating film covering the gate electrode, and an i-type a-Si layer on the gate insulating film, forming a blocking film made of metal such as Cr or the like on a channel-forming region of the i-type a-Si layer, and forming an n-type a-Si layer covering the i-type a-Si layer and the blocking film, forming a metal layer on the n-type a-Si layer, and etching a predetermined portion of the n-type a-Si layer and a predetermined portion of the metal layer, thereby forming a source electrode and a drain electrode. That portion of the blocking film which is located below a gap between the source electrode and the drain electrode is removed from the i-type a-Si layer.

    摘要: A light beam emitted by a surface illuminant reaches the surface of a transparent base layer of a recess/projection detection optical element. A light beam emitted almost vertically is emitted to an air layer. A light beam incident on the transparent base layer at an angle larger than a total reflection angle returns to a two-dimensional photosensor at a portion contacting the air layer, but scatters in a transparent particle at a portion contacting the transparent particle. When a finger is brought into contact with a scattering reflection layer, the scattering reflection state does not change in an area corresponding to a valley of a fingertip. As indicated by an arrow, an amount of reflected light beam is large. In an area corresponding to a ridge of the fingertip, the light beam scattered by the transparent particle is absorbed. The amount of reflected light beam is small, as indicated by an arrow. An image having bright and dark portions optically emphasized in correspondence with the valley and ridge of the fingertip of the finger can be obtained.

    摘要: A photosensor array is provided with one or more semiconductor layers having carrier generating regions for generating carriers by incident exciting light, and the positions of the carrier generating regions are set arbitrarily so as to equalize the balance of incident light in the direction of two-dimensional travel, so that sensing with less distortion can be achieved.

    摘要: A two-dimensional photosensor is formed on a surface light source, and a transparent conductive layer made of ITO or the like is formed on the two-dimensional photosensor. The transparent conductive layer dissipates static electricity and is grounded. Even if a finger in contact with the transparent conductive layer on the two-dimensional photosensor is charged with static electricity, this static electricity can dissipate via the transparent conductive layer. When the transparent conductive layer is divided into two layers, and the finger simultaneously touches the two transparent conductive layers, a fingerprint reading start signal is obtained. Even if, therefore, the finger is charged with static electricity, the two-dimensional photosensor can be prevented from malfunction or damage by the static electricity. When a target object in contact between the transparent conductive layers is a copy having a different resistance value, reading is not performed, and the reliability can improve.

    摘要: An electronic device includes: an operation receiving unit to receive operation from a user; a sensor to sense the user existing in a detection range of the electronic device to output detection information indicating that the user exists in the detection range; and processing circuitry to output content for assisting the user in operating the electronic device, when the processing circuitry has determined that the user exists in the detection range based on the detection information and when an elapsed time in which the operation of the user is not received at the operation receiving unit has exceeded a threshold time.
