  • Publication number: 20050240751
    Abstract: In one embodiment, a method for supporting address translation in a virtual-machine environment includes creating a guest translation data structure to be used by a guest operating system for address translation operations, creating an active translation data structure based on the guest translation data structure, and periodically modifying the content of the active translation data structure to conform to the content of the guest translations data structure. The content of the active translation data structure is used by a processor to cache address translations in a translation-lookaside buffer (TLB).

  • Publication number: 20050237475
    Abstract: In accordance with the invention, a tunable subwavelength resonant grating filter comprises a liquid crystal cell having a pair of major surface walls. One wall of the cell is a coated subwavelength grating of a SRGF. The coating comprises a polymer layer to fill the grating trenches and a surfactant layer to facilitate uniform alignment of the liquid crystal material. The refractive index of the LCD material in the cell can then be electrically or thermally adjusted to tune the resonant wavelength.

  • Publication number: 20050201656
    Abstract: An optical device for combining two orthogonally polarized beams or splitting a beam into two orthogonally polarized beams is provided that utilizes two collimating/focusing lenses and a thin film wire-grid polarizer. Because the thin film wire-grid polarizer can be fabricated in very thin profile, the provision of a thin film wire-grid polarizer allows the optical polarization beam combiner/splitter device to be highly integrated and simultaneously realize a number of performance advantages of a thin film wire-grid polarizer over other types of polarizers utilized in various prior art polarization beam combiner/splitters.

  • Publication number: 20050167046
    Abstract: In accordance with the invention, substrate-supported linear arrays are formed by the steps of adhering a thin layer of polymer between a pair of substrates and separating the substrates perpendicular to the layer. The polymer layer separates to form substrate-supported polymer gratings on both substrates, each grating having a period proportional to the thickness of the layer. The process has been used to make gratings with periods in the sub-micron range or larger over areas covering square centimeters.

  • Publication number: 20050146078
    Abstract: Apparatus for double-sided imprint lithography of an apertured substrate comprises a pair of correspondingly apertured molds, a support for an assembly of the substrate and molds, and an alignment mechanism with radially movable elements for aligning the apertures of the molds and the substrate. The movable elements can be at least partially disposed in a spindle and can be removed radially outward by a conically tapered drive rod. Opposing surfaces of the substrate can then be imprinted in registration at the same time, preferably by fluid pressure imprint lithography.

  • Publication number: 20050145119
    Abstract: Improved apparatus for imprint lithography involves using direct fluid pressure to press a mold into a substrate-supported film. Advantageously the mold and/or substrate are sufficiently flexible to provide wide area contact under the fluid pressure. Fluid pressing can be accomplished by sealing the mold against the film and disposing the resulting assembly in a pressurized chamber. The result of this fluid pressing is enhanced resolution and high uniformity over an enlarged area.

  • Publication number: 20050146079
    Abstract: The addition of thin coatings (less than and approaching monomolecular coatings) of persistent release materials comprising preferred compounds of the formula: RELEASE-M(X)n-1— RELEASE-M(X)n-m-1Qm, or RELEASE-M(OR)n-1—, wherein RELEASE is a molecular chain of from 4 to 20 atoms in length, preferably from 6 to 16 atoms in length, which molecule has either polar or non-polar properties; M is a metal atom, semiconductor atom, or semimetal atom; X is halogen or cyano, especially Cl, F, or Br; Q is hydrogen or alkyl group; m is the number of Q groups; R is hydrogen, alkyl or phenyl, preferably hydrogen or alkyl of 1 to 4 carbon atoms; and; n is the valence ?1 of M, and n?m?1 is at least 1 provides good release properties. The coated substrates are particularly good for a lithographic method and apparatus for creating ultra-fine (sub-25 nm) patterns in a thin film coated on a substrate is provided, in which a mold having at least one protruding feature is pressed into a thin film carried on a substrate.

  • Publication number: 20050037143
    Abstract: In accordance with the invention, at least one parameter of a method for imprinting a mold pattern on the surface of a workpiece is monitored or measured. The monitoring or measuring is accomplished by a) providing a mold having a molding surface configured to imprint at least a test pattern for measurement; b) imprinting the test pattern on the moldable surface by pressing the molding surface into the moldable surface; c) illuminating the test pattern with radiation during at least a portion of the imprinting, and monitoring or measuring at least one component of the radiation scattered, reflected or transmitted from the test pattern to monitor or measure the at least one parameter of the imprinting. The imprinting step typically comprises disposing the mold near the workpiece with the molding surface adjacent the moldable surface, pressing the molding surface into the moldable surface and removing the molding surface from the moldable surface to leave the imprinted pattern.

  • Publication number: 20040064813
    Abstract: In one embodiment, a method for resolving address space conflicts includes detecting that a guest operating system attempts to access a region occupied by a first portion of a virtual machine monitor and relocating the first portion of the virtual machine monitor within the first address space to allow the guest operating system to access the region previously occupied by the first portion of the virtual machine monitor.

  • Publication number: 20040033515
    Abstract: The present invention relates to a device for interfacing nanofluidic and microfluidic components suitable for use in performing high throughput macromolecular analysis. Diffraction gradient lithography (DGL) is used to form a gradient interface between a microfluidic area and a nanofluidic area. The gradient interface area reduces the local entropic barrier to nanochannels formed in the nanofluidic area. In one embodiment, the gradient interface area is formed of lateral spatial gradient structures for narrowing the cross section of a value from the micron to the nanometer length scale. In another embodiment, the gradient interface area is formed of a vertical sloped gradient structure. Additionally, the gradient structure can provide both a lateral and vertical gradient.
