ActiveUS20170053818A1Simple structureSemiconductor/solid-state device testing/measurementSolid-state devicesLight irradiationRadiation thermometer
From a stage of preheating by a halogen lamp to irradiation with a flash by a flash lamp, a radiation thermometer is used for measuring the temperature of a back surface of a semiconductor wafer. A increased temperature ΔT is determined by which the back surface of the semiconductor wafer is increased in temperature from the preheating temperature by irradiation with a flash. The specific heat of the semiconductor wafer has a known value. Further, the increased temperature ΔT is proportionate to the magnitude of energy applied to a front surface of the semiconductor wafer by irradiation with a flash. Thus, a front surface attained temperature of the semiconductor wafer can be determined using the increased temperature ΔT of the back surface of the semiconductor wafer during irradiation with a flash.
