    摘要: Methods and apparatus to validate continuous signal phase matching in high-speed nets routed as differential pairs are described. In one embodiment, a primary net of a differential pair may be traversed to determine whether a design rule violation has occurred based on comparison of calculated trace lengths of the primary net and a secondary net against a threshold value. Other embodiments are also described.

    摘要: A nanoparticle which includes a multi-armed core and surface decoration which is attached to the core is prepared. A multi-armed core is provided by any of a number of possible routes, exemplary preferred routes being living anionic polymerization that is initiated by a reactive, functionalized anionic initiator and ∈-caprolactone polymerization of a bis-MPA dendrimer. The multi-armed core is preferably functionalized on some or all arms. A coupling reaction is then employed to bond surface decoration to one or more arms of the multi-armed core. The surface decoration is a small molecule or oligomer with a degree of polymerization less than 50, a preferred decoration being a PEG oligomer with degree of polymerization between 2 and 24. The nanoparticles (particle size ≦10 nm) are employed as sacrificial templating porogens to form porous dielectrics. The porogens are mixed with matrix precursors (e.g., methyl silsesquioxane resin), the matrix vitrifies, and the porogens are removed via burnout. Greater porosity reduces the dielectric constant k of the resulting dielectrics. The porous dielectrics are incorporated into integrated circuits as lower k alternatives to silicon dioxide.

    摘要: The present invention provides a procedure for determining the octanol-water distribution coefficient P of a surface-active substance by means of the following steps: 1. equilibrating a dilute aqueous solution or dispersion of the substance with octanol 2. evaporating an aliquot of the aqueous phase and re-dissolving the residue in water or electrolyte solution 3. measuring of the surface tension of the re-dissolved residue solution 4. determining the concentration of the surface-active substance in the re-dissolved residue solution by means of a surface tension vs. concentration calibration curve 5. using the concentration of the surface-active substance in the re-dissolved residue solution to calculate the equilibrium concentration in the aqueous phase and, from the mass balance, the equilibrium concentration in the octanol phase 6. calculating the octanol-water distribution coefficient from the ratio of concentrations in octanol and water phases.
