  • Patent number: 7045903
    Abstract: A semiconductor integrated circuit comprises contact pads located over active components, which are positioned to minimize the distance for power delivery between a selected pad and one or more corresponding active components, to which the power is to be delivered. This minimum distance further enhances dissipation of thermal energy released by the active components. More specifically, a semiconductor integrated circuit comprises a laterally organized power transistor, an array of power supply contact pads distributed over the transistor, means for providing a distributed, predominantly vertical current flow from the contact pads to the transistor, and means for connecting a power source to each of the contact pads. Positioning the power supply contact pads directly over the active power transistor further saves precious silicon real estate area.

  • Patent number: 7045904
    Abstract: A patterned plasma treatment may be provided on the chip and/or the substrate to enhance the distribution of underfill material between the chip and the substrate. The underfill material is typically dispensed after the chip is electrically connected to the substrate. The chip may be electrically connected to the substrate by an array of solder bumps, as one example. The underfill material is draw into a gap between the chip and the substrate by a capillary action. The patterned plasma-treated area formed on the chip and/or on the substrate may cause greater capillary force on the underfill material, as compared to non-plasma-treated areas. Such patterned plasma-treatment area may be designed and laid out to provide for more or better control of the underfill distribution between the chip and substrate while forming a chip package.

  • Patent number: 7047284
    Abstract: A transfer request bus and transfer request bus node is described which is suitable for use in a data transfer controller processing multiple concurrent transfer requests despite the attendant collisions which result when conflicting transfer requests occur. Transfer requests are passed from an upstream transfer request node to downstream transfer request node and then to a transfer request controller with queue. At each node a local transfer request can also be inserted to be passed on to the transfer controller queue. Collisions at each transfer request node are resolved using a token passing scheme wherein a transfer request node possessing the token allows a local request to be inserted in preference to the upstream request.

  • Patent number: 7045431
    Abstract: Methods are disclosed that fabricating semiconductor devices with high-k dielectric layers. The invention removes portions of deposited high-k dielectric layers not below gates and covers exposed portions (e.g., sidewalls) of high-k dielectric layers during fabrication with an encapsulation layer, which mitigates defects in the high-k dielectric layers and contamination of process tools. The encapsulation layer can also be employed as an etch stop layer and, at least partially, in comprising sidewall spacers. As a result, a semiconductor device can be fabricated with a substantially uniform equivalent oxide thickness.

  • Patent number: 7045456
    Abstract: Methods are presented for fabricating transistor gate structures, wherein upper and lower metal suicides are formed above a gate dielectric. In one example, the lower silicide is formed by depositing a thin first silicon-containing material over the gate dielectric, which is implanted and then reacted with a first metal by annealing to form the lower silicide. A capping layer can be formed over the first metal prior to annealing, to prevent oxidation of the metal prior to silicidation, and a barrier layer can be formed over the lower silicide to prevent reaction with subsequently formed silicon material. In another example, the lower silicide is a multilayer silicide structure including a plurality of metal silicide sublayers.

  • Patent number: 7044356
    Abstract: While fabricating a packaged semiconductor chip, a wire is bonded on a chip contact pad using a wire bonding machine. A bond head of the wire bonding machine is moved relative to the chip contact pad, thereby pulling a first length of the wire out of the wire bonding machine. Part of the wire passes through a space between a first outer edge of a first bearing race and a second outer edge of a second bearing race during the pulling of the first length. The wire is bonded on a lead. A first piezoelectric element is energized in the bond head, thereby causing it to expand and press against the first bearing race, which brakes the first bearing race and brakes the wire between the first and second races. The bond head is moved relative to the lead during the braking and severs the wire proximate to the lead.

  • Patent number: 7047272
    Abstract: An arithmetic unit, for example a multiply and accumulate (MAC) unit 42, for a processing engine includes a partial product reduction tree 480. The partial product reduction tree will generate carry results and provides a final output to a final adder 470 connected to the partial production reduction tree. Unbiased rounding logic 476 is provided. A carry propagation tree is responsive to the carry results for anticipating a zero on each of N least significant bits of the final adder. When zero is anticipated on each of N least significant bits of the final adder, the carry propagation tree is operable to generate an output signal 477 which is used by the unbiased rounding stage to force the (N+1)th least significant bit of the final adder to zero.

  • Patent number: 7045425
    Abstract: The present invention facilitates semiconductor fabrication by maintaining uniform thickness of a gate oxide layer (112) during the oxide growth process of non-volatile memory devices (100). The uniform thickness of a gate oxide layer (112) is obtained by defining the boundaries of the source and drain areas (110) of a memory device (100) with the source/drain dopant masking and implanting operation. If an isolation barrier (108) is present it is kept a minimum safe distance (130) away from the periphery of the conductive gate layer (114) to avoid birds-beak regions (30) responsible for non-uniform gate oxide growth. As a result, the corresponding charge losses and weak cells are mitigated, thereby facilitating the fabrication of more reliable memory cells (100). Because a more uniform gate oxide thickness (112) is used in association with the memory cells (100), a single significantly thinner gate oxide layer (114) may be employed throughout the memory device (100).

  • Patent number: 7047268
    Abstract: A method and apparatus to reduce the amount of required memory and instruction cycles when implementing Fast Fourier Transforms (FFTs) on a computer system is described. The invention optimizes FFT software using in-place bit reversal (IPBR) implemented on a processor capable of bit reversed incrementation. Alternative embodiments implement the invention for out of place bit reversal (OOPBR) and on processors that do not support special instructions for bit reversed incrementation. The invention only generates unique bit-reversed address pairs and avoids generation of self-reversed addresses. To optimize the invention for in place bit reversal, every non-self bit reversed address in the input array is generated only once, while making simple, computationally efficient increments away from the previous pair of bit reversed addresses. The address pair generator can independently advance only one address in each address pair, and bit reversal of one address uniquely defines the other address.

  • Patent number: 7047097
    Abstract: Devices being controlled electronically via physical manipulation often display a resonance. In many circumstances, the frequency range of operation is not close to the resonance frequency. In these cases, the resonance can be removed through the use of simple compensation techniques such as filters. However, when the resonance frequency is close to the frequency range of operation and when the resonance frequency can change depending on temperature, time, and physical position of the device, simple compensation techniques cannot be used. The present invention presents a non-mechanical technique for providing compensation for devices with a shifting resonance. The non-mechanical technique allows for the compensation to be performed via computation.

  • Patent number: 7047263
    Abstract: A technique and circuit is provided for facilitating a faster settling time for a digital filter for use with an analog-to-digital converter. An exemplary technique utilizes a composite filter for a faster settling, lower noise resolution filter in a parallel configuration with a slower settling, higher noise resolution filter. As a result, valid data can be received faster for processing by the analog-to-digital converter. In addition, a composite digital filter circuit can include a three filter configuration including a fast-settling, low resolution first filter, a slower-settling, higher resolution second filter, and an even slower-settling, even higher resolution third filter, each of the filters configured in a parallel arrangement. Additional or fewer filters can also be provided. Moreover, the gain of each filter path can be suitably matched to the gain of any other filter path in the digital filter circuit to provide a filter output having an equalized gain regardless of the filter path selected.
