Filed: 1989-04-28
Abstract: PURPOSE:To improve reproducibility and to realize stability by positioning an N<+>-type region in a self-alignment manner using a dummy gate pattern and by deciding an off-set amount through directional etching treatment from a side. CONSTITUTION:High concentration impurity is ion-implanted in a self-alignment manner with a metal pattern 5 formed on an operation layer formation region 1a to position a source formation region 1s and a drain formation region 1d. An off-set amount of a gate is decided through directional etching process from a side of the metal pattern 5. A gate electrode 10 is formed by a reversing mask of the processed metal pattern 5. A relative position of a gate electrode 10, the source formation region 1s and the drain formation region 1d can be thereby decided without depending on mask alignment accuracy.

Abstract: PURPOSE:To save power consumption and to improve the uniformity of illuminance by arranging a light source irradiating an original and a reflecting plate in opposition to the original in an alternate mode while interposing an image forming optical system between them. CONSTITUTION:The light source 1 such as light emitting diode, the image forming optical system 2 where focusing transmitting bodies are arranged as an array, and the reflecting plate 5 formed flat or concaved are arranged alternately so that the light source 1 and the reflecting plate 5 are opposed while interposing the image forming optical system 2 between them. The light from the light source 1 irradiates the original 4 and a part of the reflected light is made incident to a photodetector array 3 through the image forming optical system 2. The other part of the reflected light is reflected by the reflected plate 5, irradiated again to the original 4 and reaches the photodetector array 3 through the image forming optical system 2. Thus, the correction for variation in the illuminated strength of the light source 1 or the like is corrected by increasing the light incident to the photodetector array through the reflecting plate 5 and adjusting individually the angle of the reflecting plate 5.
