Abstract

PURPOSE:To prevent the deterioration of the quality of the half product of a semiconductor device, by alternately repeating supply and exhaustion of heated inactive gas into and out of a vacuum chamber. CONSTITUTION:A half product 1 of a semiconductor device is heated in a vacuum chamber 2. The inside of the chamber 2 is evacuated with a vacuum pump 3 into a vacuum state. The vacuum pump 3 is stopped at a reached vacuum value 5. At the same time, N2 gas, which is heated in a hot N2 feeding unit 4 is injected into the chamber 2 to a preset gas pressure 6. Thereafter, the inside of the chamber 2 is heated to a preset temperature 7. The half product 1 is heated and sealed. During the heating and sealing, the inside of the chamber 2 is evacuated again to the reached value 5. Then, the heated N2 gas is injected to the preset gas pressure 6. Thereafter, these steps are alternately repeated. The atmosphere in the chamber is agitated by the repetition of said heating and exhaustion, and dispersion in temperature is eliminated. In this way, baking is performed in the state of the perfect inactive gas atmosphere.
