    摘要: A mechanism is provided for reusing importance sampling for efficient cell failure rate estimation of process variations and other design considerations. First, the mechanism performs a search across circuit parameters to determine failures with respect to a set of performance variables. For a single failure region, the initial search may be a uniform sampling of the parameter space. Mixture importance sampling (MIS) efficiently may estimate the single failure region. The mechanism then finds a center of gravity for each metric and finds importance samples. Then, for each new origin corresponding to a process variation or other design consideration, the mechanism finds a suitable projection and recomputes new importance sampling (IS) ratios.

    摘要: A protruding structure having a linear edge is formed on a substrate. The protruding structure may be a gate line of a field effect transistor. A stress-generating liner is deposited on the substrate. A non-photosensitive self-assembling block copolymer layer containing at least two immiscible polymeric block components is deposited on the stress-generating liner, and is annealed to allow phase separation of immiscible components. The polymeric resist is developed to remove at least one of the at least two polymeric block components, which formed a pattern of nested lines due to the linear edge of the protruding structure. Linear nanoscale stripes are formed in the polymeric resist which is self-aligning and self-assembled. The stress-generating layer is patterned into linear stress-generating stripes having a sublithographic width. The linear stress-generating stripes provide a predominantly uniaxial stress along their lengthwise direction, providing an anisotropic stress to an underlying semiconductor device.

    摘要: The embodiments of the invention provide SRAM cells with asymmetric floating-body pass-gate transistors. More specifically, a semiconductor device includes an SRAM cell, a first pass-gate transistor, and a second pass-gate transistor. The first pass-gate transistor is connected to a first side of the SRAM cell, wherein the first pass-gate transistor comprises a first drain region and a first source region. The second pass-gate transistor is connected to a second side of the SRAM cell, wherein the second side is opposite the first side. The second pass-gate transistor comprises a second source region and a second drain region. Furthermore, the first source region and/or the second source region comprise a xenon implant. The first drain region and the second drain region each lack a xenon implant.

    摘要: An on-chip temperature control system includes a temperature sensor, which monitors a temperature of a chip, and a hysteresis comparator which checks whether the temperature is in an acceptable range. A reference adjustment circuit is responsive to the hysteresis comparator to adjust an on-chip voltage to control the temperature locally by adjusting a local supply voltage, if the temperature is out of range.
