20100232351	UTILIZING SBAS SIGNALS TO IMPROVE GNSS RECEIVER PERFORMANCE - The present invention provides methods of improving GNSS receivers' satellite signal acquisition and TIFF performances by taking advantage of SBAS signals. Due to a SBAS satellite's geostationary position and typically strong signal, the SBAS satellite signal can be acquired more quickly than a GPS satellite signal. Once a SBAS satellite signal is acquired the Doppler frequency search uncertainty may be reduced for remaining GNSS satellites which are to be acquired. Furthermore, a satellite search list may be optimized to search for satellites close to the line of sight (LOS) of the SBAS satellite for which a signal has been acquired, in receiver “warm” and “hot” start modes. Moreover, since a SBAS signal sub-frame is only one second long, which is shorter than six seconds for a GPS signal sub-frame, synchronization of the SBAS signal sub-frame may be achieved faster than for GPS signals. With aided time information, a receiver may compute the absolute time of week (TOW) from a sub-frame synchronized SBAS signal. Therefore, without necessarily waiting for TOW to be decoded from a GPS signal and with TOW extracted from a SBAS signal, a receiver can achieve better TTFF performance.	09-16-2010

20140273491	DRY-ETCH FOR SILICON-AND-CARBON-CONTAINING FILMS - A method of etching exposed silicon-and-carbon-containing material on patterned heterogeneous structures is described and includes a remote plasma etch formed from a fluorine-containing precursor and an oxygen-containing precursor. Plasma effluents from the remote plasma are flowed into a substrate processing region where the plasma effluents react with the exposed regions of silicon-and-carbon-containing material. The plasmas effluents react with the patterned heterogeneous structures to selectively remove silicon-and-carbon-containing material from the exposed silicon-and-carbon-containing material regions while very slowly removing other exposed materials. The silicon-and-carbon-containing material selectivity results partly from the presence of an ion suppression element positioned between the remote plasma and the substrate processing region. The ion suppression element reduces or substantially eliminates the number of ionically-charged species that reach the substrate. The methods may be used to selectively remove silicon-and-carbon-containing material at more than twenty times the rate of silicon oxide.	09-18-2014
20140308816	SELECTIVE ETCH OF SILICON BY WAY OF METASTABLE HYDROGEN TERMINATION - Methods of etching exposed silicon on patterned heterogeneous structures is described and includes a remote plasma etch formed from a fluorine-containing precursor and a hydrogen-containing precursor. Plasma effluents from the remote plasma are flowed into a substrate processing region where the plasma effluents react with the exposed regions of silicon. The plasmas effluents react with the patterned heterogeneous structures to selectively remove silicon while very slowly removing other exposed materials. The silicon selectivity results, in part, from a preponderance of hydrogen-containing precursor in the remote plasma which hydrogen terminates surfaces on the patterned heterogeneous structures. A much lower flow of the fluorine-containing precursor progressively substitutes fluorine for hydrogen on the hydrogen-terminated silicon thereby selectively removing silicon from exposed regions of silicon. The silicon selectivity also results from the presence of an ion suppressor positioned between the remote plasma and the substrate processing region. The ion suppressor reduces or substantially eliminates the number of ionically-charged species that reach the substrate. The methods may be used to selectively remove silicon far faster than silicon oxide, silicon nitride and a variety of metal-containing materials.	10-16-2014

The silicon etch may be performed using plasma effluents formed from a remotely excited fluorine-containing precursor.	06-04-2015
20150214067	METHODS FOR ETCH OF SIN FILMS - A method of selectively etching silicon nitride from a substrate comprising a silicon nitride layer and a silicon oxide layer includes flowing a fluorine-containing gas into a plasma generation region of a substrate processing chamber and applying energy to the fluorine-containing gas to generate a plasma in the plasma generation region. The plasma comprises fluorine radicals and fluorine ions. The method also includes filtering the plasma to provide a reactive gas having a higher concentration of fluorine radicals than fluorine ions and flowing the reactive gas into a gas reaction region of the substrate processing chamber. The method also includes exposing the substrate to the reactive gas in the gas reaction region of the substrate processing chamber.

20120232832	Inertial Sensing With Spatially Distributed Sensor Array And Two Dimensional Data Processing - A spatially distributed MEMS inertial sensor array is designed to reduce or cancel measurement errors and to increase the signal detection accuracy.
