摘要: An ion source that utilizes exited and/or atomic gas injection is disclosed. In an ion beam application, the source gas can be used directly, as it is traditionally supplied. Alternatively or additionally, the source gas can be altered by passing it through a remote plasma source prior to being introduced to the ion source chamber. This can be used to create excited neutrals, heavy ions, metastable molecules or multiply charged ions. In another embodiment, multiple gasses are used, where one or more of the gasses are passed through a remote plasma generator. In certain embodiments, the gasses are combined in a single plasma generator before being supplied to the ion source chamber. In plasma immersion applications, plasma is injected into the process chamber through one or more additional gas injection locations. These injection locations allow the influx of additional plasma, produced by remote plasma sources external to the process chamber.

摘要: In an ion implanter, a Faraday cup is utilized to receive an ion beam generated during ion source cleaning. The detected beam has an associated mass spectrum which indicates when the ion source cleaning process is complete. The mass spectrum results in a signal composed of a cleaning agent and the material comprising the ion source. This signal will rise over time as the ion source chamber is being cleaned and will level-off and remain constant once the deposits are etched away from the source chamber, thereby utilizing existing implant tools to determine endpoint detection during ion source cleaning.
