    摘要: An optical information storage system using optical storage media including multiple data layers or stacks wherein each of the multiple data stacks has a storage density comparable to a conventional single layer optical disk. The optical data storage system comprises an optical medium having a single dedicated servo layer and multiple data stacks which each contain an embedded servo format, a servo laser beam positioned to maintain a first focus point on the dedicated servo reference layer, a read-write laser beam positioned to maintain a second focus point on one of the data stacks, a first, dedicated servo system which provides focus and tracking error correction according to error signals generated from the dedicated servo layer, and a second, embedded servo system which provides focus and tracking error correction according to error signals generated from the data stacks. The dedicated servo layer, in different embodiments of the invention, may be positioned either below or above the data stacks in the optical medium, or interposed between data stacks. The data stacks may comprise discrete physical data layers or “virtual” data layers defined by a format hologram. The servo and read-write lasers may differ in wavelength and/or polarization.

    摘要: An optical data storage system and method comprising a photopolymer medium having generally a polymerizable monomer, an active binder, a first, hologram recording polymerization initiator, and a second, data writing polymerization initiator. The monomer is preferably a cationic ring-opening monomer. The hologram recording polymerization initiator preferably comprises a sensitizer and photoacid generator which initiate a first polymerization in the medium which defines a format hologram. The format hologram recording is carried out via interference of a signal and reference beam, with the sensitizer being specific for the wavelength(s) of the signal and reference beams. The hologram recording polymerization is only partial and does not consume all of the monomer present in the photopolymer medium. A second stage, a data writing polymerization initiator, specific to a data writing beam, locally advances polymerization at selected data storage locations to alter the previously recorded format hologram, resulting in optical data storage as localized alterations in the format hologram.

    摘要: A lithography system comprises an illumination system that supplies radiation and a projection system comprising an optical system and a patterning device located at a pupil plane. The patterning device patterns the radiation and the optical system projects the patterned radiation onto a target portion of a substrate. In one example, an additional patterning device is located at an object plane of the lithography system and patterns the radiation before the patterning device at the pupil plane.

    摘要: A method for protecting a wet lens element from liquid degradation is provided. The method includes applying a thin coating of an organoxy-metallic compound to the side portions of a wet lens element to leave behind an optically inert, light absorbing metal oxide film. A liquid shield coating is applied on top of the metal oxide coating. The two coating layers protect the wet lens element from liquid degradation when the side portion of the wet lens element is submerged into a liquid. In an embodiment, the wet lens element is an immersion lithography wet lens element and the liquid is an immersion lithography liquid.

    摘要: Disclosed are highly efficient multiphoton absorbing compounds and methods of their use. The compounds generally include a bridge of pi-conjugated bonds connecting electron donating groups or electron accepting groups. The bridge may be substituted with a variety of substituents as well. Solubility, lipophilicity, absorption maxima and other characteristics of the compounds may be tailored by changing the electron donating groups or electron accepting groups, the substituents attached to or the length of the pi-conjugated bridge. Numerous photophysical and photochemical methods are enabled by converting these compounds to electronically excited states upon simultaneous absorption of at least two photons of radiation. The compounds have large two-photon or higher-order absorptivities such that upon absorption, one or more Lewis acidic species, Lewis basic species, radical species or ionic species are formed.
