Abstract: PURPOSE:To improve temperature rising and lowering characteristics and permit optical in-process measurement, by providing a shutter between a lamp and a wafer, said shutter being able to intercept both light and heat. CONSTITUTION:A low-speed shutter and a high-speed shutter are installed between a chamber 7 and a lamp 12. The low-speed shutter can intercept the light emitted from the lamp 12 and move at low speed while water-cooling a shutter plate 13, while the high-speed shutter is constituted by a considerably light shutter plate 14 and can move at high speed. Each of the drive units 15, 15' is constituted of either an air cylinder or a motor so that it is possible to control the speed with which the shutter is opened or closed. After the lamp 12 has been shielded by the low-speed shutter, the lamp 12 is turned ON. In consequence, the temperature of the shutter plates 13, 14 rises gradually. The temperature may reach one thousand and some hundreds degrees centigrade if no appropriate means is adopted. Therefore, the shutter plates 13, 14 are so designed that they can be water-cooled. When the low-speed shutter is opened, the surface temperature of the wafer rises instantaneously, and the wafer can be heated by irradiation with uniform light.
