摘要:
A method and apparatus for cleaning residue from components of an ion source region 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 or the vacuum chamber.

Methods of implanting boron-containing ions using fluorinated boron-containing dopant species that are more readily cleaved than boron trifluoride. A method of manufacturing a semiconductor device including implanting boron-containing ions using fluorinated boron-containing dopant species that are more readily cleaved than boron trifluoride. Also disclosed are a system for supplying a boron hydride precursor, and methods of forming a boron hydride precursor and methods for supplying a boron hydride precursor. In one implementation of the invention, the boron hydride precursors are generated for cluster boron implantation, for manufacturing semiconductor products such as integrated circuitry.
摘要:
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.

Fluid storage and dispensing systems, and processes for supplying fluids for use thereof. Various arrangements of fluid storage and dispensing systems are described, involving permutations of the physical sorbent-containing fluid storage and dispensing vessels and internal regulator-equipped fluid storage and dispensing vessels. The systems and processes are applicable to a wide variety of end-use applications, including storage and dispensing of hazardous fluids with enhanced safety. In a specific end-use application, reagent gas is dispensed to a semiconductor manufacturing facility from a large-scale, fixedly positioned fluid storage and dispensing vessel containing physical sorbent holding gas at subatmospheric pressure, with such vessel being refillable from a safe gas source of refill gas, as disclosed herein.
