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.

Abstract: The present invention is directed to improving the conventional high-speed cooking oven based on a combination of hot air impingement and microwave heating by providing a time-dependent spatial variation in the net air impingement and/or net microwave energy applied to the food product in the oven. This is aimed at optimizing heat transfer and microwave efficiencies in a high-speed cooking oven, thereby enabling the oven to deliver an optimal cooking efficiency in comparison to the conventional high-speed cooking oven. In addition, under the present invention, the cooking efficiency may be further optimized by dimensioning the nozzles for hot air impingement to tighten impingement plumes, subject to the space constraint of the oven's cooking chamber, and dimensioning the cooking chamber of the oven in integer multiples of the wavelength of the microwave energy to match the microwave load.
