  • Patent number: 6943783
    Abstract: This invention provides a method and apparatus for displaying an unscaled image frame on an LCD panel. The method and apparatus uses the same line buffers available to the digital signal processor DSP formerly used for scaling the displayed image up or down in size. No extra frame buffers are required by this invention since the frame rates of the source image and the LCD panel are the same. The image frame buffer is written to the LCD panel on every other panel vertical synchronization pulse. The vertical synchronization timing is shifted to the left or right in the time domain to center the image on the LCD panel.

  • Patent number: 6943040
    Abstract: A magnetic tunneling junction (MTJ) memory cell for a magnetic random access memory (MRAM) array is formed as a chain of magnetostatically coupled segments. The segments can be circular, elliptical, lozenge shaped or shaped in other geometrical forms. Unlike the isolated cells of typical MTJ designs which exhibit curling of the magnetization at the cell ends and uncompensated pole structures, the present multi-segmented design, with the segments being magnetostatically coupled, undergoes magnetization switching at controlled nucleation sites by the fanning mode. As a result, the multi-segmented cells of the present invention are not subject to variations in switching fields due to shape irregularities and structural defects.

  • Patent number: 6943992
    Abstract: An improved read-write head for use with magnetic disks is described. This improvement has been achieved by providing the read head with shields that are limited to performing only shielding and do not share other magnetic functions with parts of the write head. This allows the write pole to be located very close to the read head since the top shield is no longer required to provide a flux return path, this function now being provided by a separate return flux pole. The separation between the read and write heads is now limited only by the need to achieve an optimum vertical field profile. Two key advantages of this structure are a substantial reduction in the jagging distance of the system and a reduced interference field from the write flux.

  • Patent number: 6939747
    Abstract: An integrated circuit module has a common function known good integrated circuit die with selectable functions. The selectable functions are selected during packaging of the known good integrated circuit die. The known good integrated circuit die is mounted to a second level substrate. The second level substrate has wiring connections to the input/output pads of the known good integrated circuit die that select desired input functions and output functions. Further, the wiring connections on the second level substrate provide signal paths to transfer signals to the desired input function and signals from the desired output function, and signals to and from the common functions. Also, the wiring connections form connections between the input/output pads and external circuitry. To select the desired input functions and the desired output functions, appropriate logic states are applied to input/output pads connected to a function selector to configure a functional operation of the integrated circuit module.

  • Patent number: 6940444
    Abstract: The domino asynchronous successive approximation (ASA) analog-to-digital converter (ADC) converts an analog signal to an n-bits digital signal. The domino ASA ADC is made out of n-blocks, corresponding to the number of n-bits of the digital output. Each of these n-blocks generates a conversion bit and calibrates all following blocks, comparable to a domino structure. One key advantage of the domino ASA ADC is its modular structure; each block is independent from all others. The unity capacitors used need to be matched only within their specific blocks. The architecture is very flexible; it is possible to increase the resolution by adding more blocks of the same kind. The ASA ADC is very fast, its speed is only limited the RC constants during the sampling and measurement phase and the speed of the comparators used.

  • Patent number: 6937098
    Abstract: In a translinear amplifier, where the output voltage difference is kept at the same relative difference as the input voltage difference and which is normally formed by two current balancing circuits and some form of an amplifier stage, said amplifier stage is drastically simplified and even replaced by a simple diode. Two additional functions sharply limit the analog operating region: an added current limiting transistor on one side and the purpose use of the voltage limited by the power supply on the other side. One key objective is linearly switching on or off a transistor, and getting sharp maxima and minima of its RDSon at the extreme ends.

  • Patent number: 6935022
    Abstract: Heat dissipation during the operation of integrated circuit chips is an old problem that continues to get worse. The present invention significantly ameliorates this by placing an embedded heat pipe directly beneath the chip. Using powder injection molding, the lower portion of the package is formed first as an initial green part which includes one or more cavities. The latter are then lined with a feedstock that is designed to produce a porous material after sintering, at which time a working fluid is introduced into the porous cavities and sealed, thereby forming one or more heat pipes located directly below the chip. The latter is then sealed inside an enclosure. During operation, heat generated by the chip is efficiently transferred to points outside the enclosure. A process for manufacturing the structure is also described.

  • Patent number: 6933188
    Abstract: A process for integrating the fabrication of double diffused drain (DDD) MOSFET devices with the fabrication sub-micron CMOS devices, has been developed. The process features formation of an insulator hard mask shape on an underlying polysilicon gate structure shape in the DDD MOSFET region, while only a polysilicon gate structure shape is formed in the CMOS device region. High energy ion implantation procedures are employed to form the deep source/drain regions of the DDD MOSFET devices with the insulator hard mask shape preventing the high energy implantation procedure from disturbing the underlying channel region. An anneal procedure used activate and drive—in the implanted ions in the deep source/drain region of the DDD MOSFET device is followed by formation of the shallower source/drain regions of the sub-micron CMOS devices.

  • Patent number: 6929958
    Abstract: A method for forming small, isolated device structures by photolithography, utilizing overlapping bi-layer suspension-bridge shaped photomasks. The use of a suspended mask to define a device shape beneath it eliminates the problems associated with uneven undercutting of the usual bi-layer mask which is a stencil portion formed on a lower pedestal. In particular, the use of a suspended mask eliminates undesirable dielectric buildup around the device caused by an insufficiently undercut pedestal or of premature mask lift-off caused by an overly undercut pedestal.

  • Patent number: 6927949
    Abstract: This invention teaches a way for the shield to shield (S1-S2) distance of a magnetic read head to be reduced. The key feature is that the upper and lower dielectric layers D1 and D3, which are normally pure aluminum oxide, have each been replaced by a bilayer dielectric, which consists of aluminum oxide in contact with the shield layer followed by a layer of a high voltage breakdown material. For D1 this layer may be either tantalum oxide or tantalum nitride while for D3 our preferred material has been tantalum oxide. The addition of the two high breakdown layers allows the thickness of the upper and lower dielectric layers to be reduced without having to reduce the S2—S2 voltage difference.
