    Abstract: Dopant source gas supply arrangements and methods are described, wherein one or more dopant source gas supply vessels is contained inside an outer enclosure of an ion implantation system, e.g., in a gas box within such enclosure. In one implementation, a dopant source gas supply vessel is positioned in remote relationship to the gas box of the ion implantation system, with a dopant source gas local vessel in the gas box, and a supply line interconnecting the dopant source gas supply vessel in supply relationship to the dopant source gas local vessel, in which the supply line is adapted to flow dopant source gas from the supply vessel to the local vessel only when the ion implantation system is in a non-operational state, and to be evacuated or filled with an inert pressurized gas when the ion implantation system is in an operational state.

    Abstract: ION SOURCE CLEANING IN SEMICONDUCTOR PROCESSING SYSTEMSCleaning of an ion implantation system or components thereof, utilizing a reactive cleaning reagent enabling growth/etching of the filament in an ion source of the arc chamber, by appropriate control of temperature in the arc chamber to effect the desired filament growth or alternative filament etching. Also described is the use of reactive gases such as XeFx, WFx, AsFx, PFx and TaFx, wherein x has a stoichioimetrically appropriate value or range of values, for cleaning regions of ion implanters, or components of implanters, in in situ or ex situ cleaning arrangements, under ambient temperature, elevated temperature or plasma conditions. Among specific reactive cleaning agents, BrF3 is described as useful for cleaning ion implant systems or component(s) thereof, in in situ or ex situ cleaning arrangements. Also described is a method of cleaning the forelines of an ion implant system for at least partial removal of ionization-related deposit from said forelines, comprising contacting said forelines with a cleaning gas wherein said cleaning gas is chemically reactive with said deposit. Also described is a method of improving the performance and extending the lifetime of an ion implant system, comprising contacting the cathode with a gas mixture.[ No Suitable Figure ]
