A passive element memory array preferably biases selected X-lines to an externally received VPP voltage and selected Y-lines to ground. Unselected Y-lines are preferably biased to VPP minus a first offset voltage, and unselected X-lines biased to a second offset voltage (relative to ground). The first and second offset voltages preferably are identical and have a value of about 0.5 to 2 volts. The VPP voltage depends upon the memory cell technology used, and preferably falls within the range of 5 to 20 volts. The area otherwise required for an on-chip VPP generator and saves the power that would be consumed by such a generator. In addition, the operating temperature of the integrated circuit during the programming operation decreases, which further decreases power dissipation. When discharging the memory array, the capacitance between layers is preferably discharged first, then the layers are discharged to ground.

A non-ablative method and apparatus for making an economical glass hard disk (platter) for a computer hard disk drive (HDD) using a material machining technique involving filamentation by burst ultrafast laser pulses. Two related methods disclosed, differing only in whether the glass substrate the HDD platter is to be cut from has been coated with all the necessary material layers to function as a magnetic media in a computer's hard drive. Platter blanks are precisely cut using filamentation by burst ultrafast laser pulses such that the blank's edges need not be ground, the platter's geometric circularity need not be corrected and there is no need for further surface polishing. Thus the platters can be cut from raw glass or coated glass. As a result, this method reduces the product contamination, speeds up production, and realizes great reductions in the quantity of waste materials and lower production costs.

An adhesive sheet (S) is expanded by expanding means (20) with a plate-like article (W) being mounted to a frame (F) after dicing of the plate-like article (W) to increase spacings between individual chips (T), an expanded state of the adhesive sheet (S) is maintained by expansion maintaining means (10), so that the plate-like article (W) is able to be conveyed together with the frame (F) with the spacings between the chips (T) being maintained, thereby preventing adjacent chips (T) from interfering with each other during the conveyance. This allows the plate-like article (W) after the dicing to be conveyed together with the frame (F) without edges of the adjacent chips (T) coming into contact with each other by vibration during the conveyance to cause chipping or microcracks in the edges.

Disclosed are methods and apparatuses for determining the position of a roving receiver in a coordinate system using at least two base-station receivers, which are located at fixed and known positions within the coordinate system. The knowledge of the precise locations of the base-station receivers makes it possible to better account for one or all of carrier ambiguities, receiver time offsets, and atmospheric effects encountered by the rover receiver, and to thereby increase the accuracy of the estimated receiver position of the rover. Baselines are established between the rover and each base-station, and baselines are established between the base stations. Navigation equations, which have known quantities and unknown quantities, are established for each baseline. Unknowns for the baseline between base stations are estimated, and then used to correlate and reduce the number of unknowns associated with rover baselines, thereby improving accuracy of the rover's estimated position.

A method and device for sensing spatial variations and/or temperature variations in the locality of a fibre optic cable 1 is disclosed, wherein a broadband light source 47 is used to shine incident light onto a series of fibre Bragg gratings contained within zones A, B and C. Each zone contains a plurality of fibre Bragg gratings, the plurality of fibre Bragg gratings in any one zone having a substantially identical grating period, and the fibre Bragg gratings in the respective zones having different grating periods. The reflected light from each fibre Bragg grating is returned back down the fibre optic cable 1 and redirected via a 2×1 coupler 51 to a wavelength detection system 53 and a personal computer 63. The combination of wavelength detection system 53 and personal computer 63 allow analysis of the reflected light patterns, as well as providing a user interface which enables detection of the occurrence of a spatial and/or a temperature variation. The location of the said variation along the fibre optic cable 1 is advantageously detectable in terms of the particular zone A, B or C in which the said variation has been sensed.

Various embodiments of a TAMR head having a magnetic core antenna (MCA) with a recessed plasmon layer are disclosed. An end of the plasmon layer is separated from the ABS by a magnetic layer that transmits the plasmon mode from the plasmon layer and transmits magnetic flux from an adjacent main pole layer. Both of the MCA and magnetic layer may have a triangular shape from an ABS view. There may be a non-magnetic separation layer between the MCA magnetic core and the main pole. Furthermore, a magnetic shield may be included with a side at the ABS, a side facing an end of a waveguide that transmits electromagnetic radiation to the MCA, and a side facing an edge of the plasmon layer. The recessed plasmon layer allows an improved overlay of the thermal heating spot on the magnetic field gradient at the magnetic medium that provides better TAMR performance.

Disclosed are embodiments of a capacitor with inter-digitated vertical plates and a method of forming the capacitor such that the effective gap distance between plates is reduced. This gap width reduction significantly increases the capacitance density of the capacitor. Gap width reduction is accomplished during back end of the line processing by masking connecting points with nodes, by etching the dielectric material from between the vertical plates and by etching a sacrificial material from below the vertical plates. Etching of the dielectric material from between the plates forms air gaps and various techniques can be used to cause the plates to collapse in on these air gaps, once the sacrificial material is removed. Any remaining air gaps can be filled by depositing a second dielectric material (e.g., a high k dielectric), which will further increase the capacitance density and will encapsulate the capacitor in order to make the reduced distance between the vertical plates permanent.

A plurality of bumps is formed on a substrate. At first, a hole having a bottom is formed in a sheet, and the hole is filled with a metallic paste. Then, the sheet is stacked and positioned on the substrate so that the hole of the sheet faces an electrode of the substrate. The substrate with the sheet is heated and pressurized so that the metallic paste is sintered and bonded to the electrode so as to form the bump. Then, the sheet is separated from the substrate having the bump, so that the bump is formed on the substrate. A part of each bump does not lack, and all of the bumps are formed surely. Therefore, the bump can be formed uniformly.
