Abstract: A technique is provided to model a heat penetration profile for various targets which are non-planar or three-dimensionally shaped targets for use in a heating system. The relative volume of material that is irradiated at various depths may have an impact on the absorbed heat profile through the target. For example, a hollow cylindrical product has substantially more material per micro-meter near the outside diameter than it does near the inside diameter. Accordingly, the thickness of the wall or the diameter of the hollow inside the cylinder, as well as the outer diameter of the cylinder, have a substantial impact on the ultimate heat profile through the wall.

Abstract: A light irradiation heating process in which, even in the case of an asymmetrical physical property of an article to be treated, uniform heating is possible, or in which heating can be performed such that the article acquires a desired physical property after heat treatment. Based on the measured value of the local physical property of the article to be treated, the emissivity distribution is obtained and the distribution pattern of the light intensity on the article to be treated is determined.

According to this determined result, the intensity of the light emitted from the respective light emitting parts of the lamp units are controlled individually, and thus, the article to be treated is irradiated with light.

Abstract: Two-step photo-irradiation heat treatment is performed so that a total photo-irradiation time is not more than one second and that a first step of photo-irradiation of a semiconductor wafer is performed with a light-emission output that averages out at a first light-emission output and a second step of photo-irradiation of the semiconductor wafer is performed in accordance with an output waveform that peaks at a second light-emission output that is higher than both average and maximum light-emission outputs in the first step.

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: In light-irradiation heating with a total irradiation time of one second or less, two-stage irradiation is performed, including a first stage of light irradiation of a semiconductor wafer, which irradiation produces an output waveform that reaches a peak at a given emission output; and a second stage of supplemental light irradiation of the semiconductor wafer, which irradiation is started after the peak, producing an emission output smaller than the above given emission output. The emission output in the second stage is two thirds or less than the above given emission output at the peak. The first-stage light-irradiation time is between 0.1 and 10 milliseconds, and the second-stage light-irradiation time is 5 milliseconds or more. 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.
