Abstract: A piezoelectric sheet, which comprises a matrix comprising a polyimide, silicone rubber or an epoxy resin, and a cubic lead zirconate titanate single-crystal particle dispersed in the matrix, wherein (100) plane of said single-crystal particle is oriented parallel to a plane of said sheet, and said single-crystal particle penetrates the plane of said sheet from one to the other side.

Abstract: An oxide etching process, particularly useful for selectively etching oxide over a feature having a non-oxide composition, such as silicon nitride and especially when that feature has a corner that is prone to faceting during the oxide etch. The invention uses a heavy perfluorocarbon, for example, hexafluorobutadiene (C4F6) or hexafluorobenzene (C6F6). The fluorocarbon together with a substantial amount of a noble gas such as argon is excited into a high-density plasma in a reactor which inductively couples plasma source power into the chamber and RF biases the pedestal electrode supporting the wafer. A more strongly polymerizing fluorocarbon such as difluoromethane (CH2F2) is added in the over etch to protect the nitride corner. Oxygen or nitrogen may be added to counteract the polymerization. The same chemistry can be used in a magnetically enhanced reactive ion etcher (MERIE) or with a remote plasma source.

The amounts of the first three gases are chosen such that the ratio (F—H)/(C—O) is at least 1.5 and no more than 2. Alternatively, the gas mixture may include the heavy fluorocarbon, carbon tetrafluoride, and the diluent with the ratio of the first two chosen such the ratio F/C is between 1.5 and 2.

Abstract: A method for replacing a current operating software working with current files by a new operating software working with new files in a working network environment. Prior to replacement, the current operating software and current files reside in an active region of a network element, while the network element is active and maintains a prior operating software in a non-active region. The prior operating software is preserved in the non-active region and new operating software is downloaded to the non-active region and installed there while the current files are saved and updated to create updated files conforming to the new operating software. The network element is then rebooted such that the active region and the non-active region are swapped, thus replacing the current operating software working with the current files with the new operating software working with the updated files.
