    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 ]

    Abstract: A method and apparatus for cleaning residue from components of semiconductor processing systems used in the fabrication of microelectronic devices. To effectively remove residue, the components are contacted with a gas-phase reactive material for sufficient time and under sufficient conditions to at least partially remove the residue. When the residue and the material from which the components are constructed are different, the gas-phase reactive material is selectively reactive with the residue and minimally reactive with the materials from which the components of the ion implanter are constructed. When the residue and the material from which the components are constructed is the same, then the gas-phase reactive material may be reactive with both the residue and the component part. Particularly preferred gas-phase reactive materials utilized comprise gaseous compounds such as XeF2, XeF4, XeF6, NF3, IF5, IF7, SF6, C2F6, F2, CF4, KrF2, Cl2, HCl, ClF3, ClO2, N2F4, N2F2, N3F, NFH2, NH2F, HOBr, Br2, C3F8, C4F8, C5F8, CHF3, CH2F2, CH3F, COF2, HF, C2HF5, C2H2F4, C2H3F3, C2H4F2, C2H5F, C3F6, and organochlorides such as COCl2, CCl4, CHCl3, CH2Cl2 and CH3Cl.
