| 20090104539 | FABRICATION PROCESS FOR CHOLESTERIC LIQUID CRYSTAL MEDIA HAVING A VOLUME HOLOGRAM - A volume hologram layer ( | 04-23-2009 |
| 20090197185 | DOCUMENT RECORDING METHOD AND APPARATUS - A document recording method for recording a document on a microfilm, the document including a series of pages, a format of which is specified so as to include at least a page representing commencement, a page representing an original, and a page representing conclusion. The method includes recording all or a portion of the series of pages on the microfilm in a hologram format that is obtained by interference between object light and reference light. | 08-06-2009 |
| 20100003605 | SYSTEM AND METHOD FOR PROJECTION LITHOGRAPHY WITH IMMERSED IMAGE-ALIGNED DIFFRACTIVE ELEMENT - A novel system and method and computer program product for exposing a photoresist film with patterns of finer resolution than can physically be projected onto the film in an ordinary image formed at the same wavelength. A hologram structure containing a set of resolvable spatial frequencies is first formed above the photoresist film. If necessary the photoresist is then sensitized. An illuminating wavefront containing a second set of resolvable spatial frequencies is projected through the hologram, forming a new set of transmitted spatial frequencies that expose the photoresist. The transmitted spatial frequencies include sum frequencies of higher frequency than is present in the hologram or illuminating wavefront, increasing the resolution of the exposing pattern. These high spatial frequency transmitted waves can be evanescent, or they can propagate at a steeper obliquity in a higher index medium than is possible in a projected image. A further method is described for designing lithographic masks to fabricate the hologram and to project the illuminating wavefront. In other embodiments, a simple personalization based on Talbot fringes and plasmonic interference is performed. | 01-07-2010 |
| 20100183956 | COMPUTER GENERATED HOLOGRAM, EXPOSURE APPARATUS AND DEVICE FABRICATION METHOD - The present invention provides a computer generated hologram including a plurality of cells which form a light intensity distribution on a predetermined plane, the plurality of cells including a plurality of first cells including isotropic media and anisotropic media, and a plurality of second cells including anisotropic media alone, wherein the plurality of cells change a phase of incident light which impinges on each of the plurality of cells to form a phase distribution including N (N≧2) for each of a wavefront of a linearly polarized light component in a first direction and a wavefront of a linearly polarized light component in a second direction perpendicular to the first direction. | 07-22-2010 |
