概要（Overview）

The Therma-Probe model TP420 is a high stability automated ion implant process control system that uses a laser-based, noncontact, nondestructive measurement technique for monitoring ion implantation and other processes. It can measure implants with doses from 1x10E11 to 1x10E15 ions/cm2 and energies from 5 keV to 3 MeV. The system is capable of handling SEMI standard 100 to 200 mm wafers.
