Title: Ion implantation
Inventor: SAKAI KATSUHIKO
IPC: C23C14/48
Filed: 1992-04-16
Abstract: PURPOSE:To prevent the breakdown of a sample due to the charge of electrons by grounding an ion implantation chamber, and applying to an ion beam neutralizing electron source a potential closer to a positive side than -50 volts with respect to the ground potential to increase an accuracy in the measurement of an ion beams current. CONSTITUTION:An implantation chamber 8 which is provided with an ion beam neutralizing electron source (filament) 13, a Faraday cage 11, a sample mounting rotary disc 7 and the like, is grounded and a potential closer to a positive side then -50 volts is applied to the filament 13. Thereby, the implantation chamber 8 side weakens an attraction for electrons from the electron source 13 or repulses leakage electrons 17 to push them back to the cage 11, thereby preventing electrons from leaking out through a gap between the cage 11 and the disc 7. And all electron beams from the electron source are made to flow through the outside of the current path of a current meter 12 and only an ion current is accurately detected with the current meter 12, thereby making it feasible to implant a required ion beam into a sample.
