ActiveUS8445075B2Constant ratePrevents undercuts and CD lossVacuum evaporation coatingPretreated surfacesNitrogenThin layer
Methods of processing films on substrates are provided. In one aspect, the methods comprise treating a patterned low dielectric constant film after a photoresist is removed from the film by depositing a thin layer comprising silicon, carbon, and optionally oxygen and / or nitrogen on the film. The thin layer provides a carbon-rich, hydrophobic surface for the patterned low dielectric constant film. The thin layer also protects the low dielectric constant film from subsequent wet cleaning processes and penetration by precursors for layers that are subsequently deposited on the low dielectric constant film.

Center filled confections, such as gummy or jelly candies or fruit snacks are continuously produced by co-deposition into a mold without candy tailing to obtain products with substantially uniform side walls and little, if any, shell breakage and filler leakage or bleed-out problems. Decentering of the filler and its accompanying production of thin or weak shell walls is avoided by at least substantially preventing excessive flow of a fluid or liquid shell component along a single side of shell introduction into the manifold nozzle or nozzle cavity. At least substantially uniform flow of the shell component in an annular passageway of a co-deposition nozzle assembly may be achieved with an apertured disk insert, a plurality of manifold bores, or opposing shell component entry points to evenly distribute the shell component and prevent or substantially reduce filler leakage or bleed-out.

Method and system for adapting a wireless link to achieve a desired channel quality
InactiveUS7529548B2Reducing bandwidth of uplinkConstant overall transmission rateError preventionTransmission systemsTransmitterUplink channel
Adapting a wireless communications link between a transmitter and a receiver involves reducing the RF bandwidth of an uplink communications channel to achieve a desired channel quality. The RF bandwidth of the uplink communications channel is reduced when the desired channel quality is not achieved using the entire available RF bandwidth for uplink communications. Reducing the RF bandwidth of an uplink channel enables the uplink limit of a subscriber unit to be extended beyond what is possible when the entire available RF bandwidth is used for uplink communications. Additional uplink time slots can be allocated to the uplink communications channel with the reduced RF band so that a constant overall transmission rate can be maintained between the transmitter and the receiver.
