摘要： The capacitance between a gate electrode of a transistor and local interconnect is reduced by employing SiC sidewall spacers on the side surfaces of the gate electrode when forming the source/drain regions with shallow extensions. Embodiments include forming SiC sidewall spacers at a width of about 500 .ANG. to about 800 .ANG. having a dielectric constant of less than about 3.2, depositing a silicon oxide inter-dielectric layer, and forming the local interconnect through the inter-dielectric layer. The resulting composite dielectric constant between the gate electrode and local interconnect is about 4.2 to about 4.7.

摘要： The capacitance between the gate of a transistor and local interconnect is reduced employing SiC as an etch stop layer. Embodiments include depositing a SiC etch stop layer having a thickness of about 500-1000 Å and a dielectric constant of less than about 3.2, thereby providing a composite dielectric constant between the gate and local interconnect of between about 3.7 to about 4.7. The SiC etch stop layer can be deposited by PECVD or HDP techniques.

摘要： Air gap insulation regions are formed selectively within high parasitic capacitance regions in which conductive lines are closely proximate and generates an intolerable amount of parasitic capacitance. The selective formation of air gap insulation regions improves circuit performance by reducing the parasitic capacitance and device reliability by reducing the stress fracture problem of conventional air gap insulation schemes.

摘要： A NOR gate pair includes a first and second NOR gate, each with a plurality of inputs and an output. A first NAND gate has a first input coupled to the output of the first NOR gate, a second input coupled to the output of the second NOR gate through a first input inverter, and an output. A second NAND gate has a first input coupled to the output of the second NOR gate, a second input coupled to the output of the first NOR gate through a second input inverter, and an output. A first output inverter is coupled to the output of the first NAND gate and a second output inverter is coupled to the output of the second NAND gate. This configuration assures that NOR gates used in a one-hot-decode decoder will all have logic-low outputs during a precharge phase.

摘要： An output buffer with improved tolerance to overvoltage conditions. Among other features, especially when in a high-impedance state, the output buffer prevents a leakage path from a pad (108) through a pull-up driver (101) to supply voltage VDD when any voltage above VDD is placed on the pad (108). Further, the output buffer provides improved transient response characteristics. In one embodiment, the output buffer includes a pull-up driver (101), a first tracking transistor (120), a second tracking transistor (122), a voltage bias generator (112), and a coupling capacitor (124).

The driver has an output to supply a binary Q signal equal to the inverse of the driver input signal, in response to the driver input signal, the shadow-Q signal, and the clock signal. The shadow latch has an input to accept the driver input signal, and an input to accept the clock signal. The shadow latch has an output to supply the shadow-Q signal equal to the inverted Q signal, in response to the driver input signal and clock signal.
