Abstract:
1. An ion implantation device that implants ions in a substrate, wherein the ion implantation device has: a chamber including a cover having a small cylindrical through-hole; an irradiation means that radiates ions; a retention means that retains at least one substrate; a detection means that detects, in a noncontact state, temperature information pertaining to the temperature of a substrate retained by the aforementioned retention means, wherein the detection means comprises a thermopile located in said small cylindrical through-hole; a supply means that supplies a cooling medium to the aforementioned retention means to enable heat exchange for the substrate retained by the aforementioned retention means; and a control means that calculates the surface temperature of the substrate retained by the aforementioned retention means based on the temperature information detected by the aforementioned detection means and determines whether the calculated substrate surface temperature is within a permissible temperature range.
