Abstract:
A system (10) for in-situ generation of fluorine radicals and/or fluorine-containing interhalogen compounds XFn (wherein X is Cl, Br, or I, and n is an odd integer). Such system comprises a fluorine source (1), a halogen source (2) for supplying halogen species other than fluorine, a chamber (4) for mixing fluorine with halogen species other than fluorine, and an energy source (6) to supply energy to such chamber to facilitate reaction between fluorine and the halogen species other than fluorine. The chamber may be a semiconductor chamber (5), wherein the in-situ generated fluorine radicals and/or fluorine-containing interhalogens are employed for cleaning the processing chamber.
Abstract:
A method and apparatus for cleaning residue from components of the vacuum chamber and beamline of an ion implanter used in the fabrication of microelectronic devices. To effectively remove residue, the components are contacted with a gas-phase reactive halide composition for sufficient time and under sufficient conditions to at least partially remove the residue. The gas-phase reactive halide composition is chosen to react selectively with the residue, while not reacting with the components of the ion source region of the vacuum chamber.
Abstract:
A ventilation gas management system and process for an enclosure adapted to contain fluid supply vessel(s) and through which ventilation gas is flowed to provide safe operation in the event of leakage of fluid from a vessel. Ventilation gas flow is modulated to accommodate various hazard levels associated with the deployment and operation of such enclosure containing fluid supply vessel(s), e.g., a gas box or gas cabinet in a semiconductor manufacturing facility, thereby achieving reduction in ventilation gas requirements otherwise required for such deployment and operation.

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:
A system for delivery of low-pressure dopant gas to a high-voltage ion source in the doping of semiconductor substrates, in which undesired ionization of the gas is suppressed prior to entry into the high-voltage ion source, by modulating electron energy upstream of the high-voltage ion source so that electron acceleration effects are reduced to below a level supporting an electronic ionization cascade. The gas delivery system in a specific application includes a gas flow passage, a voltage generator electrically coupled with at least a portion of the gas flow passage to impose an electric field thereon, and an obstructive structure that is deployed to modulate acceleration length of electrons of the low-pressure gas in relation to ionization potential of the gas, to suppress ionization in the gas flow passage.
Abstract:
A delivery system and method for vaporizing and delivery of vaporized solid and liquid precursor materials at sub-atmospheric pressures between a heatable vaporization vessel and a processing tool. The system includes a pressure regulator internally positioned within the vaporization vessel and in fluid communication with a downstream mass flow controller to maintain a consistent flow of vaporized source material. The system further comprises introducing a carrier/diluent gas for diluting the vaporized source material before entry into the processing tool. A venturi is positioned directly upstream of the processing tool and provides for mixing of the carrier gas with the vaporized source material while providing the negative pressure required to open the gas pressure regulator within the vaporization vessel.

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.
