  • Patent number: 5747355
    Abstract: A method for producing a thin-film transistor (TFT) in which the gate electrode is offset from the source and drain without detriment to the characteristics of the device or to manufacturing yield, and a structure for such a TFT, are disclosed. A gate electrode is formed using a material capable of anodic oxidation, and a mask is formed on the gate electrode. Using a comparatively low voltage, a comparatively thick, porous anodic oxide film is formed on the sides of the gate electrode. The mask is then removed and using a comparatively high voltage a dense anodic oxide film is formed at least on the top of the gate electrode. Using the gate electrode having this anodic oxide on its top and sides as a mask, an impurity is introduced into the semiconductor film and an offset structure is obtained.

  • Patent number: 5068540
    Abstract: A distance measuring apparatus comprises a light emitting device for emitting infrared light blinking at a constant frequency toward an object, and a light receiving device for receiving infrared light reflected from the object. The light receiving device can generate two output signals which correspond respectively to positive and negative amounts of deviation of a position of light received therein with respect to a center thereof. The output signals are amplified by amplifiers, respectively. A signal component having a frequency corresponding to the blink frequency of the infrared light is picked up by a picking-up circuit from each of the output signals of the amplifiers. A distance determining device is provided to determine a distance to the object on the basis of the signal components. A gain control circuit for controlling gains of the amplifiers includes a pair of resistor circuits each having a changeable resistance for determining the gain of the corresponding amplifier.
