The process system includes: a sampling region for the material; an infrared photometric monitor constructed and arranged to transmit infrared radiation through the sampling region and to responsively generate an output signal correlative of the material in the sampling region, based on its interaction with the infrared radiation; and process control means arranged to receive the output of the infrared photometric monitor and to responsively control one or more process conditions in and/or affecting the process system.
Abstract: A gas cabinet including an enclosure containing at least one gas supply vessel and flow circuitry coupled to the gas supply vessel(s). The flow circuitry is constructed and arranged to flow dispensed gas from an on-stream gas supply vessel to multiple sticks of the flow circuitry, with each of the multiple sticks being joined in gas flow communication to a respective gas-utilizing process unit. The flow circuitry is valved to enable sections of the flow circuitry associated with respective ones of the multiple sticks to be isolated from other sections of the flow circuitry, so that process gas can be flowed to one or more of the sticks, while other sticks are being evacuated and purged, or otherwise are closed to dispensed gas flow therethrough.
Abstract: A fluid storage and delivery system utilizing a porous metal matrix that comprises at least one Group VIIIB metal therein. In one embodiment, the porous metal matrix forms a solid-phase metal adsorbent medium, with an average pore diameter of from about 0.5 nm to about 2 nm and a porosity of from about 10% to about 30%, which is particularly useful for sorptively storing and desorptively dispensing a low vapor pressure fluid, e.g., ClF3, HF, GeF4, Br2, etc. In another aspect, the porous metal matrix forms a solid-phase metal sorbent with an average pore diameter of from about 0.25 ?m to about 500 ?m and a porosity of from about 15% to about 95%, which can effectively immobilize low vapor pressure liquefied gas.
Abstract: A system for dispensing liquid to a manufacturing process from a container including an outer container and a flexible inner container occupied by the liquid. A flow passage provides fluid communication between an interior of the inner container and the manufacturing process. A pressurized fluid source is in fluid communication with a space between inner walls of the outer container and the inner container. The pressurized fluid source causes fluid under pressure to flow into the space between the inner walls of the outer container and the inner container to force liquid out of the inner container to the manufacturing process via the flow passage. A pressure sensor is positioned to sense pressure in the flow passage. A controller responsive to the pressure sensor controls the pressure in the flow passage by modulating the pressure from the pressurized fluid source.

Abstract: Supercritical fluid-assisted deposition of materials on substrates, such as semiconductor substrates for integrated circuit device manufacture. The deposition is effected using a supercritical fluid-based composition containing the precursor(s) of the material to be deposited on the substrate surface. Such approach permits use of precursors that otherwise would be wholly unsuitable for deposition applications, as lacking requisite volatility and transport characteristics for vapor phase deposition processes.
Abstract: The present invention relates to apparatus and method for re-circulating high viscosity liquids. The apparatus comprises a recirculating probe coupled to a fluid storage and dispensing vessel by a connector, and the recirculating probe comprises: (a) a dip tube defining an output flow path; (b) an output port; (c) a recirculating port; and (d) a return flow path. The output flow path and the return flow path preferably have substantially equal cross-sectional areas, which reduce or eliminate the unbalance between the discharge pressure in the output line and that in the re-circulation line, and prevent premature wearing-out of the dispensing/recirculating pump.

Abstract: A gas cabinet assembly for dispensing of gas to a process facility such as a semiconductor manufacturing tool. A purge gas dry scrubber is integrated with the gas flow circuitry and a venturi pump in the gas cabinet. Purge gas is flowed through the flow circuitry in the gas cabinet subsequent to on-stream dispensing of process gas through such flow circuitry, and forms a purge effluent including the residual process gas. The purge effluent is flowed through a dry scrubber unit to sorptively remove the process gas species from the purge effluent. The resultant process gas-depleted purge effluent is vented from the gas cabinet, e.g., into the ducting of the house exhaust system of the process facility. Monitoring of the relative depletion of the dry scrubbing medium in the dry scrubber may be carried out with endpoint detection, e.g., using colorimetric change techniques, toxic gas monitor devices, or PLC/CPU arrangements.
Abstract: Drying of patterned wafers is achieved in a manner effecting removal of water from the patterned wafers without collapse or deterioration of the pattern structures thereof. The drying is carried out in one aspect of the invention with a composition containing supercritical fluid, and at least one water-reactive agent that chemically reacts with water to form reaction product(s) more soluble in the supercritical fluid than water. Various methodologies are described for use of supercritical fluids to dry patterned wafers, which avoid the (low water solubility) deficiency of supercritical fluids such as supercritical CO2.

Abstract: A method of preventing oxygen deficiency in a ferroelectric or high ? film material having a top electrode layer deposited thereon. Process conditions are employed that either enable the top electrode layer to be formed without oxygen abstraction from the ferroelectric or high ? film material in the vicinity and at the top surface thereof, or else provide the ferroelectric or high ? film material in the vicinity and at the top surface thereof with a surplus of oxygen. In the latter case, the deposition formation of the top electrode layer on the ferroelectric or high ? film material depletes the over-stoichiometric excess of the oxygen in the film material, to yield a device structure including an electrode on a film material having a proper stoichiometry, e.g., of PbZrTiO3.

Abstract: A gas supply system arranged for dispensing of gas at a predetermined flow rate. The system employs a gas dispensing flow circuitry arranged for dispensing gas at selectively variable gas flow conductance conditions, to maintain the flow rate of the dispensed gas at a predetermined, e.g., constant, value in the operation of the system. The gas dispensing flow circuitry may include an array of dispensed gas flow passages, each of a differing conductance, or alternatively a variable conductance gas flow passage equipped with a variable conductance assembly for modulating the gas flow conductance of the passage, in response to sensed pressure of the gas or other system parameter. The system permits the flow rate of a dispensed gas to be maintained at a consistent desired level, despite the progressive decline in source gas pressure as the gas source vessel is depleted in use.
