Abstract: Dynamic Random Access Memory (DRAM) cells are formed in a P well formed in a biased deep N well (DNW). PMOS transistors are formed in N wells. The NMOS channels stop implant mask is modified not to be a reverse of the N well mask in order to block the channels stop implant from an N+ contact region used for DNW biasing. In DRAMs and other integrated circuits, a minimal spacing requirement between a well of an integrated circuit on the one hand and adjacent circuitry on the other hand is eliminated by laying out the adjacent circuitry so that the well is located adjacent to a transistor having an electrode connected to the same voltage as the voltage that biases the well. For example, in DRAMs, the minimal spacing requirement between the DNW and the read/write circuitry is eliminated by locating the DNW next to a transistor precharging the bit lines before memory accesses. One electrode of the transistor is connected to a precharge voltage.

Abstract: A method of planarizing a layer of dielectric material is disclosed herein that is particularly suitable for planarizing inter-layer-dielectrics (ILD) or inter-metal-dielectrics (IMD). The planarizing method comprises the steps of depositing a layer of sacrificial oxide over the dielectric material, depositing a layer of amorphous silicon over the sacrificial oxide layer by either sputtering or plasma enhanced chemical vapor deposition (PECVD) at a temperature less than about 500 degrees Celsius, performing a first chemical-mechanical polishing of the amorphous silicon layer to form a self-aligned mask for a subsequent etching step, etching a portion of the sacrificial oxide layer to form a channel therein, and performing a second chemical-mechanical polishing to remove the remaining amorphous silicon layer and the remaining sacrificial oxide, and to substantially planarize the underlying dielectric material.

Abstract: A wireless LAN RF module uses a low power transistor switchable voltage divider circuit to control the bias input of a GaAs MESFET output power amplifier. This bias control circuit provides stable, high speed on-off switching of the power amplifier stage by applying low power bias voltages to the MESFET gate input, rather than by interrupting the high power MESFET drain to Vdd circuit.

Abstract: A test head for a semiconductor integrated circuit tester comprises a housing which has an air inlet opening and an air outlet opening and bounds a pin card space and an air chamber. Multiple pin cards are located in the pin card space and radiate from an interior cavity which is within the pin card space. A baffle structure divides the air chamber, which is separated from the pin card space by a boundary surface, into an air supply duct which provides communication between the air inlet opening and the interior cavity and an outlet plenum which provides communication between the pin card space and the air outlet opening by way of the boundary surface. A fan is mounted in the interior cavity for inducing a flow of air from the interior cavity to the plenum by way of spaces between the pin cards.

Abstract: A shipping rack is provided for safe and secure transport of a plurality of generally elongate workpieces, each of the plurality of workpieces having a longitudinal axis and distinctly different first and second ends. The shipping rack comprises a rectangular base with a vertical members extending perpendicularly upwardly from the four corners of the base. Affixed to the vertical members are at least one pair of horizontal support members. Each such pair is positioned in spaced apart parallel relationship. Across the length of the horizontal support members are a plurality of pairs of alternating first and second slots for receiving the first and second respective ends of the workpieces. Because of the difference in depth of the first and second slots, the workpieces are held in the pair of support members with the axis thereof at an angle of about 5 degrees relative to the horizontal.

Abstract: A non-invasive servo-write system for use in a data recording disk drive. The system measures actuator position and generates a reference clock using semiconductor lasers. Internal position references are provided by reflective diffraction gratings affixed to the actuator arm and the spindle hub. Wavefront reconstruction optics correct for aberrations in the gratings. Optical sensors detect differential changes in the diffraction patterns created by the gratings, eliminating sensitivity to frequency drift. Decode electronics convert optical sensor data into an actuator position measurement. Control electronics drive the voice coil motor within the disk drive, which positions the write transducer to record servo information provided in a servo pattern generator. Transparent windows in the head-disk-assembly cover allow the servo-writer to write drives which are completely assembled and sealed.

Through the data communication port, data can be programmed in the EEPROMs, so that the elevator operation data (parameters) in the memory of a failed CPU can be copied to another CPU for replacement.

Abstract: A method and system for analyzing an electrogastrophic (EGG) signal are disclosed. Electrodes are positioned on abdominal skin of a subject adjacent a stomach thereof. The electrodes obtain the EGG signal produced by the stomach. An amplifier is connected to the electrodes, receives the obtained EGG signals, and amplifies the obtained EGG signal. A transforming device is operatively connected to the amplifier. The transforming device receives the amplified EGG signal and transforms the amplified EGG signal from a time domain representation to a frequency domain representation. The transformation is accomplished by way of a predetermined transform function incorporating a variable frequency and a window function. The window function has a time resolution and a frequency resolution. The frequency resolution of the window function is proportional to the frequency.

Abstract: An optical measurement system for use in a data recording disk drive includes wavefront reconstruction optics which correct and compensate for aberrations in laser beams reflected from radial and linear diffraction gratings. The reconstruction optics include two spherical lenses and two reflectors, one of each positioned on each side of a diffraction grating. Light directed from a laser beam toward the grating diffracts into a +1 order component directed at the first set of reconstruction optics and into a -1 order component directed at the second set of reconstruction optics. The reconstruction optics compensate for the variable yaw angle caused by a linear grating and for the optical wavefront aberrations caused by a radial grating.
