Patent JP-S61154063-A (JP)
Title: Optical semiconductor device and manufacture thereof
Inventor: UMEJI TADASHI
IPC: H01L27/14
Filed: 1984-12-26
Abstract: PURPOSE:To improve the sensitivity and response properties of a light-receiving element without damaging a peripheral circuit element by forming a first conduction type semiconductor layer shaped at a concentration gradient, in which impurity concentration is lowered slowly with a separation from the surface of a substrate, onto the substrate. CONSTITUTION:When beams are projected to a light-receiving element section, beams not absorbed are absorbed into a P<+> type substrate 41 and carriers are generated, but carriers in the substrate 41 have extremely short life because impurity concentration in the substrate 41 is remarkably high. Consequently, only carriers (electrons) generated in an auto-doping layer 421 in a P-type epitaxial layer 42 may be considered as a factor through which the response properties of the light-receiving element are retarded and deteriorated. Since an auto-doping layer 422 has a concentration gradient shown in the figure at that time, an electride field toward a junction region from the P<+> type substrate 41 is formed by an internal potential gradient even when an electric field is not applied from the outside. Accordingly, carriers generated in the auto-doping layer regions are accelerated by the internal electrid field and rapidly flow into the junction region, thus shortening the travelling time of carriers, then improving the response properties of the light-receiving element.

Filed: 1988-10-28
Abstract: PURPOSE:To reduce mechanical load applied to a brake, etc., and to readily recognize the stop timing by switching an optical system from low-speed traveling to a stop action in the picture reading direction. CONSTITUTION:The optical system of the title reader travels in the final normal direction A, then stops in a prescribed point (a), and does not returns. Namely, when the number of times of copying reaches the set number of copies inputted from a key part 66, or when a signal indicating that there is no copy paper is inputted from a detecting switch 67, the control part 65 of the reader judges that the current original picture reading reaches the end of the set number. Based on the judged result and the detection that the traveling optical system reaches the point (a), the traveling optical system is stopped. This detection is made by operating a timer. Consequently, the traveling optical system starts returning at a stop point 70.
