    摘要： A method for electrically connecting planar element substrates (12) to form an array (10) by forming conductive bridges (16) between metal pads (14) located on the surface of array elements (12). These bridges (16) are designed to transmit or receive visual, acoustical or other electromagnetic data and power. The conductive bridges (16) are formed to be nearly coplanar with the planar elements (12) and are made to connect the edges (14b) of pads (14) which are fused to the planar substrate (12). Metal wire (16a), solder (16b-c), a conductive polymer (16d), or a suspension of conductive particles in paste (16e) are used to bridge and electrically connect the pads (14) located on the array elements (12). The bridges (16) have a low profile, occupy a very small area and reduce the need for highly accurate alignment of adjacent substrates (12) within the tiled array (10) before electrical connections are formed. These low profile bridges (16) are especially advantageous in that they allow a protective plastic or similar cover sheet, or a liquid crystal laminate to be surface mounted on the composite array (10) without causing detrimental surface blemishes or ridges. The small area of the bridges (16) greatly reduces the non-transmitting area of the visual display. The bridges (16), being substantially narrower than the pads (14) which they connect, are more likely to connect the intended pads (14) and less likely to "short" pads (14) which are not in accurate alignment.

    摘要： A gyricon or rotating-particle display having an "eggcrate" substrate. The display includes a substrate having a cavity-containing matrix whose cavities are disposed substantially in a single layer and are arranged within the matrix substantially in a geometrically regular pattern, and a plurality of optically anisotropic particles disposed in the cavities in the substrate, with each cavity containing at most one of the optically anistropic particles. A rotatable disposition of each particle is achievable while the particle is thus disposed in the substrate; the particle, when in its rotatable disposition, is not attached to the substrate. Each particle, for example, can have an anisotropy for providing an electrical dipole moment, the electrical dipole moment rendering the particle electrically responsive such that when the particle is rotatably disposed in an electric field while the electrical dipole moment of the particle is provided, the particle tends to rotate to an orientation in which the electrical dipole moment aligns with the field. The single layer of cavities can be substantially planar, and the geometrical pattern of cavities can be a two-dimensional array pattern in the plane of the layer, such as a hexagonal, rectangular, or rhomboidal array pattern. The substrate can further include first and second members between which members the matrix is disposed; at least one of the members can include an optically transmissive window through which a flux of optical energy can pass so as to be incident on the particles.

    摘要： A method of fabrication is provided for multi-step microlithographic structures including Fresnel lenses whereby the process includes the formation of intermediate etch stop layers that are embedded with the structure material. This is accomplished in one aspect of the invention by depositing Fresnel lens material using known techniques and the selectively altering the chemistry of the material being deposited to form the intermediate etch stop layers at suitable positions without interrupting the deposition process. In another aspect, etch stop layers are patterned on layers of the lens material and embedded between such layers. The structure, or lens, is then formed using masking, patterning and etching techniques.
