Abstract: PROBLEM TO BE SOLVED: To diffuse impurities, without generating oxidation of a silicon wafer and without breaking a container or the like by a method, wherein impurity gas generated by heating an impurity storage part, which is continually connected with a heat-treating part, at a temperature higher than the boiling point of the impurities is brought into contact with a wafer held in the interior of the heat-treating part. SOLUTION: A heat-treating part 1a is formed in a heat-levelling space by a heater 3 in the interior of a reaction tube 2. A wafer 5 is held at a fixed positions to come into contact with an impurity gas in the interior of the part 1a, and the reaction of gas to a solid is caused or a heat treatment for impurity diffusion is performed on the wafer 5. That is, the wafer 5 is charged in the part 1a in a heating furnace 1 and is heated to 600 to 700 deg.C, for example. At this time, a carrier gas is sent into the part 1a from an impurity gas introducing tube 51, and it is preferable that the interior of the part 1a be kept at a pressure of 1.33×10<-3> Pa, for example. With the condition of this pressure and the temperature, an impurity storage part 10 is quickly heated to 300 deg.C or thereabouts, for example, the reaction of the wafer 5 with P vapor is fully made to execute and a desired amount of P is made to adhere to the surface of the wafer.
