Title: Photomask for fine machining
Inventor: TAKAOKA HIDEJI
IPC: G03F1/52
Filed: 1990-06-11
Abstract: PURPOSE:To prevent the photomask from deforming, to improve the accuracy, and to repeating the same process scores of times by forming a reflecting film which reflects irradiation light sufficiently at a shield part. CONSTITUTION:For example, many small holes are formed as a mask pattern in a thin plate 4 of stainless steel, ceramic, etc., to form transmission parts where light is transmitted and shield parts 6 where the light is cut off. The reflecting films 7 which reflect light with target wavelength are formed at the shield parts 6 so as to prevent thermal variation due to light absorption. The reflecting films 7 are formed of, for example, Al vapor-deposited films or dielectric multi-layered films which reflect ultraviolet rays of, for example, 150 - 400nm with high reflectivity. Consequently, the deformation is eliminated regardless of irradiation with laser light, high accuracy of several mum and less is obtained, and the machining is repeated many times.

IPC: H01L21/78
Filed: 1992-06-12
Abstract: PURPOSE:To form a good-quality film with high productivity by keeping a film-formed substrate in a water-vapor atmosphere under 0.1-10Torr pressure, while the temperature of the film-formed substrate is raised from room temperature to film-forming temperature, and thereafter by starting film forming in a film-forming method through an atomic layer deposition method. CONSTITUTION:A rotator holding a sample S is placed in a reaction chamber 30 and rotated at 60rpm at the time of film forming or temperature rise. The inside of the reaction chamber 30 is exhausted of the air by a turbo-molecular pump VP to high vacuum. While the temperature of the reaction chamber rises from room temperature to 500 deg.C film-forming temperature, water vapor is caused to continue to flow through control valve V2 from an inlet N2 and adjusted by an orifice valve OF so that the pressure in the reaction chamber is 1Torr. In this case, Ar gas is used as the carrier gas of water vapor and the flow rate of the Ar gas is 200SCCM. At the time of film forming, the control valve V1 is opened and a fixed quantity of TMA gas 32 is introduced by the use of Ar gas as carrier gas. The flow rates of raw material gases are 100SCCM in the case of H2O gas and 40SCCM in the case of TMA gas.

Abstract: PURPOSE: To secure the selective recovery of valuable metals by masking the obstructing action of iron ion by the procedure in which when a heavy metals-mixed aqueous solution containing iron ion is treated by a froth treatment method, a compound capable of forming aluminium ion upon dissociation is added in advance.  
     CONSTITUTION: A heavy metals-mixed aqueous solution containing copper, nickel, cobalt, zinc, etc., together with iron ion, is subjected to a froth treatment using a froth treating agent, e.g., a polyamine derivative. In this case, a compound, e.g., ammonium alum, etc., which is capable of forming aluminium ion upon dissolution in water, is added in advance as a masking agent for dissolved iron in more than equivalent of objective heavy metal for selective recovery, and then a froth treating agent is added in a proportion of more than 2 mole per one atom gram of the objective heavy metal. Thus, it is possible to mask the obstructing action of iron ion present in solution and thus to recover objective heavy metals in the form of froths, leaving iron component intact in solution.

Filed: 1981-09-29
Abstract: PURPOSE:To raise the efficiency in recovering heat produced when hydrogen is occluded in a hydrogenated metal, by arranging a plurality of tubes incorporating therein a hydrogenated metal in a container having walls made of a heat- insulating material, and connecting a heat exchanging fluid inlet pipe to the container in a direction perpendicular to the tubes. CONSTITUTION:A plurality of tubes 3 incorporating therein a hydrogenated metal 2 are arranged in a flat container 1 having walls made of a heat-insulating material, in parallel to each other and in an upper and a lower, two stages but in the manner that they are located in a zigzagged manner as viewed in cross section. A hydrogen gas inlet pipe 4 is connected to one end of each tube 3. On the other hand, a heat exchanging fluid inlet port 5 is formed at a side wall 1b while a heat exchanging fluid outlet port 7 is formed at the opposite side wall. With such an arrangement, when hydrogen gas is supplied into the tubes 3 from the pipe 4, the hydrogenated metal 2 occludes hydrogen and produces heat. Here, since the heat exchanging fluid flows perpendicularly to the  axes of the tubes 3 from the inlet port 5 to the outlet port 7, heat can be transmitted uniformly, so that the heat transfer efficiency is raised.
