HEAT TREATMENT METHOD AND HEAT TREATMENT APPARATUS
20210272827 · 2021-09-02 ·

The semiconductor wafer is preheated by halogen lamps and then heated by a flash of light irradiation from flash lamps. A length of a light emission waveform of a flash of light applied from the flash lamps can be adjusted as appropriate. A data collection cycle (sampling interval) of a radiation thermometer that measures a surface temperature of the semiconductor wafer is made variable, and the longer the light emission waveform of the flash of light, the longer the data collection cycle. Even when a rising and falling time of the surface temperature of the semiconductor wafer changes due to the length of the light emission waveform of a flash of light, a temperature change can be included in a temperature profile with a constant number of data points until the surface temperature rises, goes through a maximum reaching temperature, and falls.

Light-irradiation heat treatment apparatus

A semiconductor wafer held by a holding part in a chamber is irradiated and heated with halogen light emitted from a plurality of halogen lamps. A cylindrical louver and an annular light-shielding member, both made of opaque quartz, are provided between the halogen lamps and the semiconductor wafer. The outer diameter of the light-shielding member is smaller than the inner diameter of the louver. Light emitted from the halogen lamps and passing through a clearance between the inner wall surface of the louver and the outer circumference of the light-shielding member is applied to a peripheral portion of the semiconductor wafer where a temperature drop is likely to occur. On the other hand, light travelling toward an overheat region that has a higher temperature than the other region and appears in the surface of the semiconductor wafer when only a louver is installed is blocked off by the light-shielding member.
