摘要:
Monotomic dopant ions for ion implantation are supplied from vapour of a species containing plural atoms of the desired dopant. The vapour is fed to a plasma chamber and a plasma produced in the chamber with sufficient energy density to disassociate the vapour species to produce monatomic dopant ions in the plasma for implantation.
