IPC: H01L21/82
Filed: 1991-09-27
Abstract: PURPOSE:To enlarge position-aligning margin without widening a lower interconnection layer and to avoid the conduction between the upper and lower wiring layers by filling and flattening an insulating material around the lower wiring layer, thereafter forming an amorphous semiconductor film on and around the lower wiring layer, then providing an interlayer insulating film, and forming contact holes. CONSTITUTION:Photoresist 11 is applied, exposed and developed. Thus, windows 12 for exposing an antifuse-forming region A and its surrounding region and a conducting region B are formed. Then, an interlayer insulating film 10, which is exposed through the windows 12, is removed by reactive ion etching, and contact holes 13 are formed. An amorphous silicon film 9 is formed in the surface region A and its surrounding area. Therefore. a lower interconnection layer 5a is not directly exposed through the contact holes 3 even if the contact holes 13 are formed at the parts deviated from the antifuse forming region A. A high-melting-point metal film 14 is laminated on the entire surface by a sputtering method and the like. An aluminum film 14 containing 1% silicon is grown thereon.

Abstract: PURPOSE:To sufficiently suppress the harmful carrier components generated by two-dimensional sampling of subject images by three sheets of double refractive plates. CONSTITUTION:Quartz crystal plates 11 to 13 are so laminated and stuck to each other that the quartz crystal plate 12 exists in the middle. The quartz crystal plate 13 exists in the position nearest a solid-state image pickup element side and the incident light via an image pickup lens is made incident from the quartz crystal plate 13. The main surface 14 of the quartz crystal plate 11 has an angle of +45 deg. with the horizontal scanning direction of the image pickup element and separates an extraordinary light component to a distance of (sq. rt. 2/2)Px. The main surface 15 of the quartz crystal plate 12 aligns to the horizontal scanning direction and separates the extraordinary light component to a distance of Px. The main surface 16 of the quartz crystal plate 13 has an angle of -45 deg. with the horizontal scanning direction and separates the extraordinary light component to the distance of (sq. rt. 2/2)Px. As a result, the incident light is separated to 8 pieces of rays and the positions of respective four pieces of the rays constitute a first square shape and a second square shape shifted by the prescribed distance in the scanning direction with respect to the first square shape.

IPC: C25D21/12
Filed: 1990-09-19
Abstract: PURPOSE:To form a plating on the surface of a material in uniform thickness and to prevent the penetration of an impurity metal ion into a plating soln. by automatically supplying a weak current to the material when a conveyor line is stopped. CONSTITUTION:In the device for electroplating a material, the current value outputted from a rectifier is automatically reduced when a line for conveying a material to be plated in a plating soln. is stopped for a specified time due to JAM, etc., and a constant weak current of <= about 0.1A/dm<2> is impressed on the material. Consequently, the material is plated at an extremely low depositing rate of <= about 0.01mum/min.

Abstract: PURPOSE:To pickle stably a steel strip and to prevent generation of sludge in a pickling soln. by charging continuously fresh acid to a specified amt. of the pickling soln. circulated between a pickling tank and a circulation tank and withdrawing continuously the pickling soln. exceeding the specified amt. therefrom. CONSTITUTION:The fresh acid in a storage tank 14 is supplied by a metering pump 16 into a circulation tank 6 and at the same time water for adjusting concn. is supplied through a water feed pipe 20 into the tank 6. The ratio between the fresh acid and water in this case is determined from the target acid concn. and the total amt. of the fresh acid and water is determined by the prescribed equation. The pickling soln. in the tank 6 adjusted to the prescribed concn. in the above-mentioned way is pumped 7 through a heat exchanger 13 into a pickling tank 1. The pickling soln. used for pickling of a steel strip 2 in the tank 1 has some carry-over by the evaporation and the strip 2 but is mostly returned through an overflow pipe 12 into the tank 6. While the pickling soln. is circulated in such a way, the fresh acid and water are replenished into the soln. in the tank 6 and therefore only the soln. equiv. to the difference between the increase and the decrease in the tank 1 is stored temporarily in a waste acid tank 24 through an overflow pipe 26.

Filed: 1990-09-20
Abstract: PURPOSE:To make it possible to perform the intended measurement without rotating a polarizer by analyzing the profile obtained from the output pattern of interference fringe obtained in an image detecting device, and detecting the polarized state of light to be measured. CONSTITUTION:A pair of polarizers 16A and 16B are arranged in the polarizing direction of + or -45 deg. with respect to the longitudinal direction of the slit at the double slits 16 of a Young's interferometer 18. An anlyzer 20 is set so that its polarizing direction is in parallel with the longitudinal direction of the slits 14 and 16. Therefore, the polarizing direction of the analyzer 20 forms the angles + or -45 deg. and -45 deg. with respect to the pair of polarizers 16A and 16B. An image detecting device 22 is made to be the two-dimensional sensor and can detect interference fringes. An image analyzing device 24 obtains the variable density, i.e. the profile, of the interference fringes obtained with the device 22 and analyzes the profile. Thus, the polarized state of the emitted light from a light source to be measured 12 is detected. A polarized-state output device 26 outputs the result of the analysis of the device 24.
