摘要： A light-receiving element array is provided in which the degradation of characteristic thereof due to the crosstalk may be prevented. An n-InP layer, an i-InGaAs layer, and an n-InP layer are stacked on an n-InP substrate. Zn is diffused into the topmost n-InP layer to form a p-type diffused region, resulting in a pin-photodiode. A passivation layer is deposited on the structure to a thickness such that a nonreflective condition is satisfied. On the passivation film, a light-shielding film is provided so as to cover the area between light-receiving elements.

摘要： A method for dicing a semiconductor wafer into chips is provided, in which the peeling-off of a hard protective film on the surface of a semiconductor substrate may be avoided. Two parallel grooves are formed at a dicing area around a chip by an etching process. Then, SiO2 film is deposited on the GaAs substrate as a protective film. At this time, a bending portion at the interface between the protective films on the inner surface of the groove and the surface of the substrate. When the part between two grooves is cut by a dicing blade, a stress to the protective film caused by the edge of the blade is concentrated to the bending portion, resulting in a crack along the bending portion.

摘要： A self-scanning light-emitting element array is disclosed. A coupled array of light-emitting elements is constituted so that a light-emitting element which is turned on influences a light-emitting element to be turned on next so that its threshold level is changed. When each element is clock-driven by a common drive pulse, the change in threshold level is shifted in the array direction, so that a turn-on operation is transferred in a clock period of the drive pulse.

摘要： A surface light-emitting element having improved external light emission efficiency and a self-scanning light-emitting device using this surface light-emitting element are provided. To improve external light-emission efficiency, the light-emitting center is shifted to an area where there is no light shielding layer thereon. To achieve this, an insulating layer is provided on the electrode portion above which there is a light-shielding layer at a portion making contact with the semiconductor layer thereunder so as to prevent the injected current from flowing from that electrode portion. To increase the amount of light emission, the peripheral length of the electrode is increased. With an electrode of the same area, the larger the peripheral length, the larger becomes the amount of light emission because the current injected from the electrode is distributed evenly over the entire surface, causing light to emit evenly. When the surface light-emitting element is a surface light-emitting thyristor of the PNPN structure, it is necessary to have such a construction that part of the injected current is prevented from flowing toward the gate electrode to improve external light emission efficiency. The self-scanning light-emitting device of this invention is accomplished by using this type of surface light-emitting element.

摘要： A self scanning light-emitting array is disclosed. A coupled array of light-emitting elements is constituted so that a light-emitting element in a minimal conducting state influences the next light-emitting element so that its threshold level is changed. When each element is driven by a common clock pulse, the change in threshold level is shifted in the longitudinal direction, so that a minimal conducting state is transferred in a clock period of the clock pulse.

摘要： An optical active matrix display uses a light beam through a plurality of lightguide paths in a transparent substrate for switching signals to display an image. The display includes end surfaces of the lightguide paths appearing on one side surface of the transparent substrate. A light source issues at least one light beam. A rotating polygon mirror scans the direction of the light beam. An optical system changes an angle of the light beam reflected by the rotating polygon mirror so that the light beam is incident at the end surface of the lightguide paths irrespective of the scanning direction. The optical system subjects the principal rays of the light beam to a substantially constant angle with respect to the end surfaces of the lightguide paths.
