ABSTRACT:
In photo-irradiation heating with a total photo-irradiation time of one second or less, after initial photo-irradiation of a semiconductor wafer is performed while increasing an emission output to a target value, succeeding photo-irradiation of the semiconductor wafer is performed while maintaining the emission output within a range of plus or minus 20% from the target value. The photo-irradiation time for the initial photo-irradiation ranges from 0.1 to 10 milliseconds, and the photo-irradiation time for the succeeding photo-irradiation ranges from 5 milliseconds to less than one second. This allows the temperature of the semiconductor wafer even at a somewhat greater depth below the surface to be raised to some extent while allowing the surface temperature to be maintained at a generally constant processing temperature, thus achieving both the activation of implanted ions and the repair of introduced defects without any thermal damage to the semiconductor wafer.
