  • Patent number: 7576904
    Abstract: The present invention is directed to an electro-magnetophoresis display having either the traditional up/down or dual switching mode. The display cells are filled with an electro-magnetophoretic dispersion comprising particles suspended in a solvent and the particles are both charged and magnetized. The display of the invention prevents undesired movement of the particles in the cells. The magnetic force generated by the magnetic layer(s) eliminates the need to provide cells with a threshold voltage high enough to avoid the cross talk and/or cross bias effects. In addition, the dual switching mode allows the particles to move in the up/down direction as well as the planar direction, thus providing a multicolor display of high color quality at very low cost.

  • Publication number: 20090104550
    Abstract: A nanoscale lithographic method in which a reusable conductive mask, having a pattern of conductive surfaces and insulating surfaces, is positioned upon a substrate whose surface contains an electrically responsive resist layer over a buried conductive layer. When an electric field is applied between the conductive mask and buried conductive layer, the resist layer is altered in portions adjacent the conductive areas of the mask. Selective processing is performed on the surface of the substrate, after mask removal, to remove portions of the resist layer according to the pattern transferred from the mask. The substrate may be a target substrate, or the substrate may be utilized for a lithographic masking step of another substrate. In one aspect of the invention the electrodes to which the charge is applied are divided, such as into a plurality of rows and columns wherein any desired pattern may be created without the need to fabricate specific masks.
