Abstract: A method of fabricating an integrated circuit with ultra-shallow source and drain junctions utilizes a dummy or sacrificial gate spacer. Ions are implanted and dopants are provided through the openings associated with sacrificial spacers to form the source and drain extensions. The openings can be filled with an insulative layer. The process can be utilized for P-channel or N-channel metal oxide semiconductor field effect transistors (MOSFETS).

Abstract: An ultra-low thermal budget process is provided for channel implant by using a reverse process sequence where a conventional MOS transistor is formed without the channel implant. The originally deposited polysilicon gate is removed, a nitride film deposition and etch is used to form a nitride spacer with a predetermined configuration, and a self-aligned channel implant is performed. After the channel implantation, anneal and super-retrograded doping, the nitride spacer and the gate oxide are removed for subsequent regrowth of a second gate oxide and a polysilicon deposition to form a second polysilicon gate.

Abstract: A method for making a ULSI MOSFET includes establishing a void in a field oxide layer on a silicon substrate and filling the center of the void with a gate electrode. A high-k gate insulator is sandwiched between the gate electrode and the substrate. Around the void, a low-k gate spacer is formed, with the gate spacer being disposed directly above the source and drain extensions of the MOSFET.

Abstract: The present invention relates to methods for cryopreserving plant cells and to methods for recovering viable plant cells from long or short term cryopreservation. Plant cells to be cryopreserved can be grown in culture and pretreated with a solution containing an cryoprotective agent and a stabilizer. Pretreated cells are acclimated to a reduced temperature and loaded with a cryoprotective agent such as DMSO, propylene glycol or polyethylene glycol. Loaded cells are incubated with a vitrification solution which, for example, comprises a solution with a high concentration of the cryoprotective agent. Vitrified cells retain less than about 20% water content and can be frozen at cryopreservation temperatures for long periods of time without significantly altering the genotypic or phenotypic character of the cells. Plant cells may also be cryopreserved by lyophilizing cells prior to exposure to a vitrification solution. The combination of lyophilization and vitrification removes about 80% to about 95% of the plant cell's water. Cells can be successfully cryopreserved for long periods of time and viably recovered. The invention also relates to methods for the recovery of viable plant cells from cryopreservation. Cells are thawed to about room temperature and incubated in medium containing a cryoprotective agent and a stabilizer. The cryoprotective agent is removed and the cells successfully incubated and recovered in liquid or semi-solid growth medium. The invention also relates to the cryopreserved cells and to viable plant cells which have been recovered from long or short term cryopreservation.

Abstract: Disclosed is an aircraft environmental control and fuel tank inerting coupling system based on a membrane separation method. The dehumidification of gas in an aircraft environmental control system and the separation of oxygen and nitrogen in a fuel tank inerting system are realized respectively, based on the selective permeability of a membrane to water vapour/air and oxygen/nitrogen. In the coupling system, part of drying gas passing through a membrane dehumidification heat exchanger (5) enters a membrane air separator (9), and the other part thereof is cooled through a large expansion turbine (8) and then directed into a cockpit for refrigeration; and nitrogen-rich gas generated by the membrane air separator (9) is directed into a fuel tank for inerting. Oxygen-rich gas is mixed with gas supplied by the environmental control system, thus increasing the oxygen content of gas supplied by the aircraft cockpit.

Abstract: A method and system for dynamic adjustment of downlink/uplink resource allocation ratio in a long-term evolution (LTE) time division duplex (TDD) system is disclosed. The method includes replacing at least one uplink subframe in a subframe pattern with at least one of a mute subframe and a mute uplink pilot timeslot (UpPTS), within a geographical guard area that isolates at least two areas having different TDD allocation patterns. The method further includes scheduling an uplink transmission from at least one mobile terminal such that the at least one of the mute subframe and the mute UpPTS are unused. A simple solution or a TDD configuration index substitution solution, or any combination thereof, may be used to control the uplink transmission involving a mute subframe or a mute UpPTS.
