  • Patent number: 6110257
    Abstract: A low concentration gas delivery system utilizing a sorbent-based gas storage and delivery unit including a gas storage and dispensing vessel joined in flow communication with a permeation structure. The storage and dispensing vessel contains a solid-phase physical sorbent medium holding a fluid, which is selectively dispensed from the vessel by pressure differential, concentration differential and/or thermal desorption techniques. The dispensed gas flows to the permeation structure, wherein the desorbed fluid is diffusionally released either as a neat fluid, or into a carrier gas in which the desorbed fluid has a precisely maintained concentration, for applications such as calibration of instruments monitoring fluid concentrations, delivery of dopants for fabrication of microelectronic device structures, or other end use application requiring a precise low concentration of fluid.

  • Patent number: 6108236
    Abstract: A smart card having integrated circuitry including a single chip embedded microcontroller for controlling all processes and transactions that take place on the card. The single chip embedded microcontroller comprises a processor, a non-volatile erasable PROM communicating with the processor for reading and writing information to and from the PROM, and an error check and correction circuit cooperating with the PROM to correct errors occurring during the read and write operations after the PROM has performed a greater number of read and write cycles than its endurance. By such arrangement, the accuracy of the read and write operations on the smart card is maintained beyond the endurance of said PROM, enabling PROM-based smart cards having endurance on the order of 100,000 read and write cycles.

  • Patent number: 6101816
    Abstract: A fluid storage and dispensing system comprising a vessel for holding a fluid at a desired pressure. The vessel has a pressure regulator associated with a port of the vessel, and set at a predetermined pressure. A dispensing assembly, e.g, including a flow control means such as a valve, is arranged in gas/vapor flow communication with the regulator, whereby the opening of the valve effects dispensing of gas/vapor from the vessel. The fluid in the vessel may be constituted by a liquid which is confined in the vessel at a pressure in excess of its liquefaction pressure at prevailing temperature conditions, e.g., ambient (room) temperature. A phase separator such as a gas/vapor-permeable liquid-impermeable membrane, may be associated with the regulator, as a barrier to flow of liquid into the regulator, when the contained fluid in the vessel is in a liquid state.

  • Patent number: 6099653
    Abstract: A liquid reagent delivery and vaporization system, including a housing defining a flow passage for flow of a process fluid therethrough. A vaporizer element is positioned within the housing and includes a heated vaporization surface. Liquid reagent is selectively delivered to the heated vaporization surface, to vaporize the liquid reagent and form reagent vapor for flow through the flow passage of the housing, e.g., to a chemical vapor deposition reactor for deposition of a film on a substrate. A thermal damping fluid source is arranged to selectively deliver a thermal damping fluid into the flow passage to maintain a predetermined thermal condition therein. For example, the system may be arranged to selectively terminate delivery of liquid reagent to the vaporization surface and to contemporaneously selectively initiate delivery of the thermal damping fluid into the flow passage to maintain a thermal condition thermally matches the vaporization conditions when the liquid reagent is vaporized.
