摘要： An ion implantation system and method, providing cooling of dopant gas in the dopant gas feed line, to combat heating and decomposition of the dopant gas by arc chamber heat generation, e.g., using boron source materials such as B2F4 or other alternatives to BF3. Various arc chamber thermal management arrangements are described, as well as modification of plasma properties, specific flow arrangements, cleaning processes, power management, eqillibrium shifting, optimization of extraction optics, detection of deposits in flow passages, and source life optimization, to achieve efficient operation of the ion implantation system.

摘要： Cleaning 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.
