摘要： PURPOSE:To obtain a solid-state image pickup device with little random noise by a method wherein a portion under a diffused layer contacting with a vertical signal line is constructed by a four-layer structure composed of n -p -p -p well deposit layers. CONSTITUTION:A p layer 12 is provided between an n diffused layer 4 and a p layer 6. Regarding this p 12, it can be said that when an impurity, e.g. phosphorus, opposite to the one of the p layer 6 is diffused into this layer, an n type impurity is put into a p type impurity layer and consequently the density of the p layer 6 is reduced equivalently. Assuming that the impurity density of the p layer 6 is Np , the capacity Cv of a vertical signal line 11 is reduced by the reduction of the density of the p layer 6, since Cvproportional (Np ) . By this constitution, random noise can be lessened, and thus an image having a high S/N ratio and a very high quality can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a gas dust collecting system which can automatically and easily prepare an assay sample containing contaminants contained in the ambient air at concentrations which are several of tens of times higher than the normal levels. SOLUTION: At the time of preparing an assay sample by mixing an appropriate amount of the steam of pure water in a gas sucked from the ambient air and cooling the gas together with the moisture originally contained in the air in a condenser 8, the sucking amount of the gas, mixing amount of the steam of pure water, and the cooling temperature of the condenser 8 are adjusted and controlled by means of a feedback control system 19 so that the preparing speed of the assay sample can become a desired value. A gas dust collecting system is automatically and carefully cleaned before collecting a new assay sample so that the contaminants sucked from a previous environment and remaining in the system cannot make analysis results erroneous by taking that the concentrations of the contaminants to be analyzed are generally very low into consideration.

摘要： PURPOSE:To offer a solid-state image pickup device generating no difference between the dark current of an output from a photo-diode side in an effective picture element area and the dark current of an output from a photo-diode side out of the effective picture element area. CONSTITUTION:At the photo-diode 21 in the effective picture element area, the structure of a read-out gate 39 superposed on an N-type diffusion layer is partially notched. On the other hand, at the photo-diode not functioning as the effective picture element, the structure of an opening in a light shielding film 45 is exposed. By such structure, at the time of annealing, both influences of anneal effect on a shift-register 23 are made equal. Consequently, dark currents generated at the shift-register 23 are made equal in both areas.

摘要： PURPOSE:To obtain a highly sensitive solid state image pick-up element, by making the impurity concentration in a P well lower than that on the side of an N-type substrate at a P-N junction part with an N layer, thereby effectively utilizing optical signal charge. CONSTITUTION:On an N-type silicon substrate 1, a P well 2, N layers 3 and 4 and a signal line 5 are formed. The N layers 3 and 4 and a gate electrode 7 form an MOS transistor. The P well 2 and the layer 3 form a photodiode. The MOS transistor acts as a switching element, which reads signal charge stored in the layer 3. The P well 2 is formed as follows. At first, a P layer 21 is formed on the substrate 21. Then, a P-type epitaxial layer 22 is formed. Thereafter, the N layer 3 is formed. Electrons, which are generated in the P well, are drifted to a P-N junction part with the N layer 3, i.e., to the photodiode and effectively utilized as a signal.

摘要： PROBLEM TO BE SOLVED: To produce a stable catching liquid of a high concentration by feedback controlling conditions of each process based on a catching liquid-producing speed measured at an exit of a condenser. SOLUTION: Gas dust components in a gas sucked through a suction opening 5 are mixed with pure water vapor supplied from a pure water vapor feed system 2 and taken into a condensed liquid while cooled and condensed at a condenser 8. The mixture is sent down to a collecting tank 11 and stored. A catching liquid level detector 11a for monitoring a catching liquid-producing speed is set in the collecting tank 11 and a position of a liquid level of the collecting tank 11 is detected. The producing speed is operated with a ratio of a volume of the collecting tank 11 up to the detector 11a and a time since the collecting tank 11 is empty until the liquid level is detected by the detector 11a. When the monitored producing speed is smaller (larger) than a required value, a pure water feed pump 16 is feedback controlled to increase (decrease) the feed amount of pure water. Accordingly, since the feed amount of pure water vapor is corrected, a continuously stable catching liquid of a high concentration is produced.
