  • Publication number: 20080258186
    Abstract: A silicon on insulator device has a silicon layer (10) over a buried insulating layer (12). A nickel layer is deposited over a gate (16), on sidewall spacers (22) on the sides of the gate (16), and in a cavity on both sides of the gate (16) in the silicon layer (10). A doped amorphous silicon layer fills the cavity. Annealing then takes place which forms polysilicon (40) over the sidewall spacers (22) and gate (16), but where the nickel is adjacent to single crystal silicon (10) a layer of NiSi (44) migrates to the surface leaving doped single crystal silicon (42) behind, forming in one step a source, drain, and source and drain contacts.

  • Publication number: 20080258781
    Abstract: A multi-bit, programmable, modular digital frequency divider divides an input frequency by an m-bit integer divisor to produce an output frequency. The integer divisor re-initializes m-number of flip-flop stages with the divisor input at the end of every output clock. Each divisor bit is gated to a D-input through a respective data multiplexer controlled by a clock output. A run/initialize mode controller receives the input frequency and produces the divided output frequency and controls the timing of the re-initialization.

  • Patent number: 7439759
    Abstract: As technology scales, on-chip interconnects are becoming narrower, and the height of such interconnects is not scaling linearly with the width. This leads to an increase of coupling capacitance with neighboring wires, leading to higher crosstalk. It also leads to poor performance due to poor RC response at the receiving of the wire, which may even result in failure in very noisy environments. An adaptive threshold scheme is proposed in which receiver switching thresholds are adjusted according to the detected noise in bus lines. These noise levels are dependent on both the front-end processing (transistor performance) as well as on the backend processing (metal resistance, capacitance, width and spacing). The circuit therefore automatically compensates for process variations.

  • Patent number: 7440738
    Abstract: A receiver (100) adjusts its overall gain based on the detected power level of an incoming signal. The receiver is built with two detectors (D1, D2) which operate with different detecting ranges within the dynamic range of the incoming signal. If the actual power level of the incoming signal falls within one of the resolving ranges, an automatic gain control adjusts the gain of the receiver to a corresponding gain value. If not, the resolving range of one of the two detectors is shifted and eventually reduced to cover the portion of the dynamic range in which the power level is comprised. The gain of the receiver is then temporarily adjusted and a new measurement is carried out by the detector using the new resolving range. The AGC then re-adjusts the gain of the receiver based on the measurement given by the modified detector.

  • Publication number: 20080252507
    Abstract: An integrating analog to digital converter (ADC) is disclosed that comprises a Delay Locked Loop (DLL) (2, 50) which is synchronized to a reference clock signal (12). A rising edge of a clock signal therefore propagates through the DLL once each clock cycle. In use, the integrating ADC converts an analog input signal to a digital output signal dependent upon a timing measurement of an integration carried out by an integrator (4). The timing measurement is taken by reading the logical states of the individual delay cells in the DLL. This enables the position of the rising edges of the clock signal to be determined and used as a timing measurement. The timing measurement is in the form of a digital thermometer code that can be converted into a binary number. By using a DLL to take a timing measurement, the effect of process and temperature variations is reduced by the closed loop feedback of the DLL. In another embodiment, a multiplying DLL (MDLL) is used.

  • Publication number: 20080251867
    Abstract: An integrated array of non volatile magnetic memory devices, each having a first magnetic layer (10) with a fixed magnetization direction; a free magnetic layer (20) with a changeable magnetization direction; a spacer layer (30) separating the first magnetic layer and the free magnetic layer, and a switch (40) for selecting the device, the layers and at least part of the switch being formed as a columnar structure such as a nanowire. The switch is preferably formed integrally with the columnar nano-structure. By incorporating the switch in the columnar structure with the magnetic layers, the device can be made smaller to enable greater integration. This can be applied to magnetic devices using external fields or those using only fields generated in the columnar structure. A write current can be coupled along the columnar structure in a forward or reverse direction to alter the direction of magnetization of the free magnetic layer according to the direction of the current.

    Abstract: There is described a method of manufacturing a damascene interconnect (1) for a semiconductor device. A non conductive diffusion barrier (10) is formed over the wall(s) of a passage (7) defined by a porous low K di-electric material (6) and over the surface of a copper region (3) that closes one end of the passage (7). The non-conductive barrier layer (10) is plasma treated to transform an upper portion thereof (10b) into a conductive layer, while a low portion thereof (10a) comprising material that has penetrated pores of the di-electric material remains non-conductive. The passage (7) is then filled with a second copper region (13) forming an electrical interconnect with the first copper region (3) via the now conductive upper portion (1Ob) of the barrier (10). As a person skilled in the art will know, all embodiments of the invention described and claimed in this document may be combined without departing from the scope of the invention.
