Abstract: PURPOSE:To enable diffused region in specific concentration to be formed by a method wherein an oxide film is formed on the surface of an ion-implanted silicon substrate whereto the other silicon substrate is made closely adhere to form an electrostatic junction so that aluminum may be diffused in the oxide film as a diffusion source by the heat generated during the electrostatic junction process. CONSTITUTION:A single crystal silicon substrate 1 is implanted with aluminum ions. Next, a thermal oxide film 4 is formed on the surface of the silicon substrate 1. Next, another silicon substrate 5 not implanted with ions is made to closely adhere to the thermal oxide film 4 to form an electrostatic junction to be directly joined. In the case of the electrostatic junction, most of the aluminum implanted in the silicon substrate 1 is externally diffused in the oxide film 4 by the heat generated during the electrostatical junction process to be rediffused in the silicon substrates 1, 5 on both sides of the aluminum by continuous heating process. Through these procedures, the other aluminum diffused regions 6, 7 in the same impurity concentration and diffusion depth can be formed on the two isolated silicon substrates 1, 5 by removing the oxide film 4.

Filed: 1991-03-26
Abstract: PURPOSE:To obtain the thin-film diode which is not deteriorated in display quality by providing a silicon film as a light absorption film between a substrate and a semiconductor film. CONSTITUTION:The silicon film 13 consisting of amorphous silicon or polycrystalline silicon is provided on the substrate 11 and a transparent conductive film 15 is provided on the silicon film 13. Further, the semiconductor film 17 and a wiring 19 are provided.

Since the silicon film 13 provided between the semiconductor film 17 and the substrate 11 has the same wavelength absorption characteristic as the wavelength absorption characteristic of the semiconductor film 17 in such a manner, the light entering from the substrate side does not arrive at the semiconductor film 17 and the leak current occurring in the photoirradiation is not therefore generated. Further, the silicon film 13 does not form a capacity. Then, the liquid crystal display device which obviates the deterioration in the display quality is obtd.

Abstract: PURPOSE:To obtain images magnified in a vertical direction free from notches. CONSTITUTION:The timing for resetting a counter 19 for thinning is changed by as much as one horizontal scanning line between odd lines and even lines by the output of a selector 32.

In case of a glare-proof state, a high frequency of a frequency dividing circuit 25 and the voltage are impressed to the liquid crystal cell 3 through the second AND circuit 27 and the OR circuit 29, the liquid crystal layer 10 of the liquid crystal cell 3 becomes DELTAepsilon<0 by the high frequency, and the liquid crystal molecule 10a of the liquid crystal layer 10 orients its long axis direction in the direction parallel to both glass substrates 6, 13. In this way, a thermal oscillation at the time of the non-glare-proof state can be prevented.

Abstract: PURPOSE:To improve the coupling efficiency of optical transmission lines and a light source exciting light signals therein by filling the spacings between a plurality of optical transmission lines with transparent material and enclosing this with a metal body having total reflectivity. CONSTITUTION:Spacings between a plurality of optical transmission lines 2 consisting of fibers are filled and integrated by optically transparent material 4, which is then enclosed by a metal body 1 such as of stainless steel pipe or the like having total reflectivity. At the time when the light 5 incident to the transparent body part (a) propagates while causing total rflection at (c) and (f), is crosses the optical transmission lines 2 at the active regions (b), (d), (e), (g), (h), but since the widths of the active regions differ only by about 2 digits as compared to the propagating light wavelength, part of the light migrates to the active region 2. As a result, when the number of fibers is let n and the inside diameter of the sleeve d, then the coupling efficiency may be considerably improved in the handle fibers of larger n/d, i.e., filled at a higher density.
