Title: Electrophotographic receptor
Inventor: NEMOTO SHIGEMITSU
IPC: G03G5/02
Filed: 1980-02-06
Abstract: PURPOSE:To improve characteristics of a photoreceptor, by using an interlayer having minute hollow granules provided between a photoconductive layer and an insulating layer, and filling the recesses of the photoconductive layer with these granules in order to form a smooth layer of uniform thickness. CONSTITUTION:A photoconductive layer containing photoconductor 2 dispersed into a binder, interlayer 6 containing minute hollow granules 5, and insulating layer 4 are laminated on substrate 1 to form an electrophotographic receptor. Since this photoconductive layer is porous, a coating fluid for forming layer 4 invades the recesses of the photoconductive layer, resulting in rendering characteristics of the photoreceptor nonuniform. Since the recesses where the photoconductor pigment bound with the binder is absent in the surface are filled with the minute granules 5 by forming interlayer 6 or interlayer 6 containing minute hollow granules 5, for example, microencapsulated granules, the photoconductive layer becomes uniform in thickness and insulating layer 4 becomes also uniform in accordance with the photoconductive layer.

Filed: 1987-01-23
Abstract: PURPOSE:To execute the pattern-superposing exposure with high alignment accuracy without lowering the throughput by using identical light for alignment and exposure in a method wherein patterns are to be superposed during the exposure using an excimer laser. CONSTITUTION:A resist 2 is coated on a semiconductor substrate 1 where an alignment mark 3 is formed. First patterns 4 are formed on the semiconductor substrate. The alignment mark 3 is illuminated with an excimer laser beam, as the light for alignment use, which is the same light as the light to be used during a subsequent exposure process; after a signal of the reflected light has been processed, the alignment is executed in such a way that the first patterns and second patterns are superposed in prescribed positions. After completion of the alignment, the second patterns are exposed with the light 10B through a reticle 6; after development, resist patterns 8 according to the second patterns are formed. By this method, because the upper position and the lower position on the semiconductor substrate are completely identical during the alignment, the exposure can be executed while the high accuracy after completion of the alignment is maintained.

Title: Optical integrated circuit device
Inventor: TAKIGAWA SHINICHI
IPC: H01L27/095
Filed: 1986-01-27
Abstract: PURPOSE:To remarkably accelerate an optical responding speed to an input pulse by forming a semiconductor laser, an FET for an inverter and a resistor on the same GaAs substrate. CONSTITUTION:A BTRS type semiconductor laser A, an FET B for applying an inverter function and a resistor C are formed don a conductive GaAs substrate 1. In this case, the current flowing to the resistor C is so integrated as to be the sum of the current flowing to the laser A and the current flowing to the FET B. Since the laser A becomes non light emission when the FET B is ON and emits a light in case of OFF, this optical integrated circuit includes an inverter. Accordingly, a pulse signal is inverted to calculate the output of a light output. Thus, the inverter is associated in the integrated circuit to accelerate the responding speed to an input pulse 5 times or more as compared with a conventional one in which the inverter is composed separately.
