Abstract:
An apparatus and methods of improving the ion beam quality of a halogen-based source gas are disclosed. Unexpectedly, the introduction of a noble gas, such as argon or neon, to an ion source chamber may increase the percentage of desirable ion species, while decreasing the amount of contaminants and halogen-containing ions. This is especially beneficial in non-mass analyzed implanters, where all ions are implanted into the workpiece. In one embodiment, a first source gas, comprising a processing species and a halogen is introduced into a ion source chamber, a second source gas comprising a hydride, and a third source gas comprising a noble gas are also introduced. The combination of these three source gases produces an ion beam having a higher percentage of pure processing species ions than would occur if the third source gas were not used.

Claim (Index 1):
A method of implanting a workpiece, comprising:\n energizing a first source gas, comprising a processing species and fluorine, a second source gas, comprising hydrogen and at least one of silicon and germanium, and neon in a chamber to form a plasma in the chamber; and accelerating ions from the plasma toward the workpiece, wherein the workpiece is disposed in the chamber, wherein an amount of neon, by volume, introduced in the chamber is selected so that a number of pure processing species ions extracted from the plasma as a percentage of all processing species-containing ions increases by at least 5%, as compared to a baseline when neon is not used.
