Title: Making method of reflection-preventing film of photoelectric converter
Inventor: IGAWA YASUO
IPC: H01L31/0216
Filed: 1978-11-08
Abstract: PURPOSE:To raise the efficiency of light reception, by dipping the light reception face of a photoelectric converter in a mixed solution of hydrofluoric acid and nitric acid at a prescribed ratio when making a reflection-preventing film for the photoelectric converter having a silicon crystal substrate. CONSTITUTION:An n-type layer is produced on a p-type silicon crystal substrate so that a solar battery is manufactured by a conventional method. The solar battery is dipped in a mixed solution of 100 parts by volume of hydrofluoric acid and 0.5- 3.0 parts by volume of nitric acid for several to scores of seconds. As a result, a bluish film is produced on the surface of the solar battery. The film acts to prevent reflection. As for a pn junction type solar battery having an n-type layer on its light reception face, such dipping treatment is effected while an inverse bias of 0.5-0.1V is applied to the pn junction. As for a pn junction type solar battery having a p-type layer on the light reception face, such dipping treatment is effected while strong light is irradiated upon the light reception face. A uniform film is thus produced.

Abstract: PURPOSE:To measure a hit ratio in real time by obtaining the hit ratio according to the control signal of hardware. CONSTITUTION:If data to be accessed lies in a cache memory 4 when a CPU 1 outputs a signal, the inverse of OCS and accesses a memory, a cache control circuit 2 selects the cache memory 4 to allow the CPU 1 to access the cache memory 4. If data to be accessed does not lie in the cache memory 4, the cache control circuit 2 outputs a signal, the inverse of AS, selects a main memory 3, and allows the CPU 1 to access the main memory 3. Access to the main memory 3 takes more time than access to the cache memory 3. Therefore, if the usage ratio (hit ratio of the cache memory 4 is improved, the processing of an overall device can be sped up.
