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.

Ventilation gas management systems and processes

An adsorption structure is described that includes at least one adsorbent member formed of an adsorbent material and at least one porous member provided in contact with a portion of the adsorbent member to allow gas to enter and exit the portion of the adsorbent member. Such adsorption structure is usefully employed in adsorbent-based refrigeration systems. A method also is described for producing an adsorbent material, in which a first polymeric material provided having a first density and a second polymeric material is provided having a second density, in which the second polymeric material is in contact with the first polymeric material to form a structure. The structure is pyrolyzed to form a porous adsorbent material including a first region corresponding to the first polymeric material and a second region corresponding to the second polymeric material, in which at least one of the pore sizes and the pore distribution differs between the first region and the second region.

Component for solar adsorption refrigeration system and method of making such component

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 XeF, XeF, XeF, NF, IF, IF, SF, CF, F, CF, KrF, Cl, HCl, ClF, ClO, NF, NF, NF, NFH, NHF, HOBr, Br, CF, CF, CF, CHF, CHF, CHF, COF, HF, CHF, CHF, CHF, CHF, CHF, CF, and organochlorides such as COCl, CCl, CHCl, CHCland CHCl.

A fluid storage and dispensing vessel having associated therewith a colorimetric member that is effective to change color in exposure to leakage of a gas contained in the vessel. The colorimetric member may be constituted by a film, e.g., of a shrink-wrap character, that contains or is otherwise associated with a colorimetric agent undergoing color change in exposure to fluid leaking from the vessel. Such shrink-wrap film may be applied to a portion of the vessel susceptible to leakage, or alternatively to the entire vessel, so that the film is colorimetrically effective to indicate the occurrence of a leakage event by visually perceptible change of color.

An apparatus and process for abating at least one acid or hydride gas component or by-product thereof, from an effluent stream deriving from a semiconductor manufacturing process, comprising, a first sorbent bed material having a high capacity sorbent affinity for the acid or hydride gas component, a second and discreet sorbent bed material having a high capture rate sorbent affinity for the same gas component, and a flow path joining the process in gas flow communication with the sorbent bed materials such that effluent is flowed through the sorbent beds, to reduce the acid or hydride gas component.
