Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for carrying a substrate in and out of a chamber capable of preventing the generation of particles by eliminating the difference between the internal and external pressures of reaction tubes at the time of carrying the wafer in and out of the reaction tubes. SOLUTION: A differential pressure gage is installed to a discharge port 36 up to a main valve 109 and a differential pressure gage is installed to the outside of the reaction tube 14. The pressures in the reaction tubes 14, 16 are detected by the differential pressure gage and the pressures outside the reaction tubes 14, 16 are detected by the differential pressure gage. After the treatment of the wafer 20 is executed under a reduced pressure, N2 is injected into the reaction chambers 14, 16. When boat down is executed at the point of the time there is no more pressure difference between the differential pressure gage and the differential pressure gage, the opening in the state that the pressure on the outside of the reaction tubes 14, 16 and the pressure in the reaction tubes 14, 16 are equaled to the same pressure is made.  The occurrence of the return of the particles from a discharge port 36, etc., are thus prevented even if the boat is drawn out.

Filed: 1987-11-24
Abstract: PURPOSE:To obtain sintered body of magnetic alloy having high sintering density and excellent magnetic characteristics, by shaping by compression the powdered steel in which the specified amount of ingredient elements is mixed beforehand in the form of powdered iron alloy. CONSTITUTION:The title sintered body comprises powdered steel including 98 or more wt.% steel and powdered iron alloy including 30 or more wt.% steel and 15-25wt.% silicon, with 1/5 or less as diameter as the powdered steel. The percentage by weight of said powdered iron alloy to the powdered steel is 10-30%. The mixture of such ingredients is annealed under vacuum or in an non-oxidizing atmosphere at the temperature of 700-900 deg.C to stick the powdered iron alloy on the surface of the powdered steel. The powdered magnetic alloy thus formed is shaped by compression and sintered under vacuum or in non-oxidizing atmosphere at the temperature of 1250 deg.C or more for solidification. This provides the alloy with high sintering density and excellent direct current magnetic characteristics. Sintering at the temperature of 1250 deg.C or more for solidification to produce the melt of powdered Fe-Si alloy at said sintering temperature leads to liquid phase sintering for the increased density and improved magnetic characteristics.
