Abstract:
1. A method for correcting the temperature of a substrate in an ion implantation device, for which the temperature correction method includes steps wherein: a dummy silicon substrate on which is attached a thermo label for the purpose of monitoring the substrate surface temperature is retained by a retention member; the temperature information for the dummy silicon substrate is detected when ion implantation is performed on the dummy silicon substrate, and the substrate surface temperature is monitored based on the aforementioned thermo label; the relationship between the temperature information for the aforementioned dummy silicon substrate and the observed substrate surface temperature is recorded; next, the temperature information for an actual process silicon substrate is detected when ion implantation will be performed or is being performed on the process silicon substrate; the surface temperature of the process silicon substrate is calculated based on the detected temperature information and the aforementioned recorded relationship; and it is determined whether the calculated surface temperature is within a permissible temperature range.
