The condensed light for heating a substrate is transmitted through the optical fiber 130 to a processing system 100 including a thermal processing process installed in a clean room 200 in order to heat a substrate set in the processing system 100. In this regard, the optical transport medium is held at 200 deg.C or below in order to reduce the optical transport loss due to fluctuation in the optical absorption wavelength characteristics caused by temperature rise down to 10% or below. This system reduced unnecessary dissipation of energy and realizes quick and uniform heating of substrate up to a desired temperature.
