  • Publication number: 20080105900
    Abstract: A channel 16 of a FinFET 10 has a channel core 24 and a channel envelope 32, each made from a semiconductor material defining a different lattice structure to exploit strained silicon properties. A gate is coupled to the channel envelope through a gate dielectric. Exemplary materials are Si and SixGe1-x, wherein 78<x<92. The channel core 24 has a top surface 26 of width wc and an upstanding surface 28, 30 of height hc, preferably oriented 90° to one another. The channel envelope 32 is in contact with the top 26 and upstanding surfaces 28, 30 so that the area of interface is increased as compared to contact only along the top surface 26, improving electrical conductivity and gate 18 control over the channel 16. The height hc can be tailored to enable a smaller scale FET 10 within a stabilized SRAM. Various methods of making the channel 16 are disclosed, including a mask and etch method, a handle wafer/carrier wafer method, and a shallow trench method.

  • Publication number: 20080094878
    Abstract: A ring oscillator row circuit for evaluating memory cell performance provides for circuit delay and performance measurements in an actual memory circuit environment. A ring oscillator is implemented with a row of memory cells and has outputs connected to one or more bitlines along with other memory cells that are substantially identical to the ring oscillator cells. Logic may be included for providing a fully functional memory array, so that the cells other than the ring oscillator cells can be used for storage when the ring oscillator row wordlines are disabled. One or both power supply rails of individual cross-coupled inverter stages forming static memory cells used in the ring oscillator circuit may be isolated from each other in order to introduce a voltage asymmetry so that circuit asymmetry effects on delay can be evaluated.

  • Publication number: 20080026512
    Abstract: An Integrated Circuit (IC) chip that may be a bulk CMOS IC chip with silicon on insulator (SOI) Field Effect Transistors (FETs) and method of making the chip. The IC chip includes areas with pockets of buried insulator strata and FETs formed on the strata are SOI FETs. The SOI FETs may include Partially Depleted SOI (PD-SOI) FETs and Fully Depleted SOI (FD-SOI) FETs and the chip may include bulk FETs as well. The FETs are formed by contouring the surface of a wafer, conformally implanting oxygen to a uniform depth, and planarizing to remove the Buried OXide (BOX) in bulk FET regions.

  • Publication number: 20080019200
    Abstract: A multi-threshold integrated circuit (IC) that may be supplied by multiple supplies, with an array of latches such as an array static random access memory (SRAM) cells and a CMOS SRAM with improved stability and reduced subthreshold leakage. Selected devices (NFETs and/or PFETs) in array cells and support logic, e.g., in the data path and in non-critical logic, are tailored for lower gate and subthreshold leakage. Normal base FETs have a base threshold and tailored FETs have a threshold above. In a multi-supply chip, circuits with tailored FETs are powered by an increased supply voltage.

  • Publication number: 20070291562
    Abstract: Internally asymmetric methods and circuits for evaluating static memory cell dynamic stability provide a mechanism for raising the performance of memory arrays beyond present levels/yields. By altering the internal symmetry of a static random access memory (SRAM) memory cell, operating the cell and observing changes in performance caused by the asymmetric operation, the dynamic stability of the SRAM cell can be studied over designs and operating environments. The asymmetry can be introduced by splitting one or both power supply rail inputs to the cell and providing differing power supply voltages or currents to each cross-coupled stage. Alternatively or in combination, the loading at the outputs of the cell can altered in order to affect the performance of the cell. A memory array with at least one test cell can be fabricated in a production or test wafer and internal nodes of the memory cell can be probed to provide further information.

  • Publication number: 20070242513
    Abstract: The present invention provides an improved SRAM cell. Specifically, the present invention provides an SRAM cell having one or more sets of stacked transistors for isolating the cell during a read operation. Depending on the embodiment, the SRAM cell of the present invention can have eight or ten transistors. Regardless, the SRAM cell of the present invention typically includes separate/decoupled write word and read word lines, a pair of cross-coupled inverters, and a complimentary pair of pass transistors that are coupled to the write word line. Each set of stacked transistors implemented within the SRAM cell has a transistor that is coupled to a bit line as well as the read word line.
