Abstract: PURPOSE:To suppress an irregularity of temperature in the surface of a board upon radiation of a lamp by placing an article to be heat treated under pressure of the atmospheric pressure or less. CONSTITUTION:In a short time heat treating method for heat treating with a lamp 1, the atmosphere of an article 2 to be heat treated is held at pressure of the atmospheric pressure or less, and heat treated. For example, it is evacuated in vacuum (at less than 10<-4>Torr) by a pump instead of introducing atmospheric gas N8 into a quartz glass core tube 5. After Si<+> is poured 5X10<12>cm<-2> with 100keV of pouring energy to an undoped semi-insulating GaAs board 2, it is heat treated at 950 deg.C by using a halogen lamp 1 for 5sec.

Therefore, a temperature distribution in the surface of the board becomes uniform, and device characteristics in the board is made uniform. As a result, noise margin of a circuit is improved, an IC can be accelerated in operation, and its yield is further improved.
