Abstract:
An ion implantation process for making a doped Si-containing film, comprising:providing a Si-containing film on a substrate; providing an ionization chamber upstream of the substrate; introducing a dopant precursor to the ionization chamber, wherein the dopant precursor comprises at least one silicon atom and at least one Group III or Group V atom; ionizing at least a portion of the dopant precursor to form dopant excited species by applying electromagnetic energy to the dopant precursor; applying a magnetic field to the dopant excited species to create a sub-population of mass-selected dopant excited species; and directing at least a portion of the sub-population of mass-selected dopant excited species onto the Si-containing film to produce the doped Si-containing film.
