Abstract

An intensity of a power laser beam applied to a semiconductor device is adjusted. An applied intensity of the power laser beam is indicative of a magnitude at which the power laser beam is emitted toward the semiconductor device and a reflection intensity of a probing laser beam applied to the semiconductor device is indicative of an emissivity of the semiconductor device. The reflection intensity of the probing laser beam is measured to determine the emissivity of the semiconductor device and the applied intensity of the power laser beam is adjusted as a function of the emissivity.
