The first adjacent cell has a first border pin with a first routing line. The second adjacent cell has a second border pin with a second routing line. The first and second routing lines overlap to define an edge-edge stitch to couple the first and second border pins. The master pattern layout is decomposed into sub-patterns.

    摘要: Integrated circuits with stressed transistors are provided. Stressing transistors may increase transistor threshold voltage without the need to increase channel doping. Stressing transistors may reduce total leakage currents. It may be desirable to compressively stress N-channel metal-oxide-semiconductor (NMOS) transistors and tensilely stress P-channel metal-oxide-semiconductor (PMOS) transistors to reduce leakage currents. Techniques that can be used to alter the amount of stressed experienced by transistors may include forming a stress-inducing layer, forming a stress liner, forming diffusion active regions using silicon germanium, silicon carbon, or standard silicon, implementing transistors in single-finger instead of multi-finger configurations, and implanting particles. Any combination of these techniques may be used to provide appropriate amounts of stress to increase the performance or decrease the total leakage current of a transistor.

    摘要: An integrated circuit with memory elements is provided. The memory elements may have memory element transistors with body terminals. Body bias control circuitry may supply body bias voltages that strengthen or weaken memory element transistors to improve read and write margins. The body bias control circuitry may dynamically control body bias voltages so that time-varying body bias voltages are supplied to memory element transistors. Address transistors and latch transistors in the memory elements may be selectively strengthened and weakened. Process variations may be compensated by weakening fast transistors and strengthening slow transistors with body bias adjustments.

    摘要: Mixed gate metal-oxide-semiconductor transistors are provided. The transistors may have an asymmetric configuration that exhibits increased output resistance. Each transistor may be formed from a gate insulating layer formed on a semiconductor. The gate insulating layer may be a high-K material. Source and drain regions in the semiconductor may define a transistor gate length. The gate length may be larger than the minimum specified by semiconductor fabrication design rules. The transistor gate may be formed from first and second gate conductors with different work functions. The relative sizes of the first and gate conductors in a given transistor control the threshold voltage for the transistor. A computer-aided design tool may be used to receive a circuit design from a user. The tool may generate fabrication masks for the given design that include mixed gate transistors with threshold voltages optimized to meet circuit design criteria.

    摘要: A method for improving analog circuits performance using a circuit design using forward bias and a modified mixed-signal process is presented. A circuit consisting plurality of NMOS and PMOS transistors is defined. The body terminal of the NMOS transistors are coupled to a first voltage source and the body terminal of the PMOS transistors are coupled a second voltage source. Transistors in the circuit are selectively biased by applying the first voltage source to the body terminal of each selected NMOS transistor and applying the second voltage source to the body terminal of each selected PMOS transistor. In one embodiment, the first voltage source and the second voltage source are modifiable to provide forward and reverse bias to the body terminal of the transistors.

    摘要: Conventional CMOS devices suffer from imbalance because the mobility of holes in the PMOS transistor is less than the mobility of electrons in the NMOS transistor. The use of strained silicon in the channels of CMOS devices further exacerbates the difference in electron and hole mobility, as strained silicon provides a greater increase in electron mobility than hole mobility. However, hole mobility is increased in the SiGe layer underlying the strained silicon layer. Therefore, a more evenly-balanced, high-speed CMOS device is formed by including strained silicon in the NMOS transistor and not in the PMOS transistor of a CMOS device.

    摘要: An n-type MOSFET (NMOS) is implemented on a substrate having an epitaxial layer of strained silicon formed on a layer of silicon germanium. The MOSFET includes first halo regions formed in the strained silicon layer that extent toward the channel region beyond the ends of shallow source and drain extensions. Second halo regions formed in the underlying silicon germanium layer extend toward the channel region beyond the ends of the shallow source and drain extensions and extend deeper into the silicon germanium layer than the shallow source and drain extensions. The p-type dopant of the first and second halo regions slows the high rate of diffusion of the n-type dopant of the shallow source and drain extensions through the silicon germanium toward the channel region. By counteracting the increased diffusion rate of the n-type dopant in this manner, the shallow source and drain extension profiles are maintained and the risk of degradation by short channel effects is reduced.
