  • Publication number: 20060019411
    Abstract: A storage container for receiving precision substrates such as wafers, having increased strength and improved drying ability when washed. The storage container has a letter L-shaped circumferential wall (12) projectingly provided on an outer wall face, the circumferential wall functioning as a gasket insertion groove (12a). A first flange (13) horizontally extending from the lower end face of the letter L-shaped circumferential wall (12) and a second flange (14) horizontally extending from a position 10-30 mm lower than the first flange are respectively formed integrally with the container. Vertical ribs (15) are formed between the lower face of the first flange (13) and the upper face of the second flange (14).

  • Patent number: 6962770
    Abstract: In a method of manufacturing an electroconductive film, a developing process is implemented on a photosensitive paste layer (12) having a height of about 13 ?m in a state where exposure is repeated twice in FIG. 1D, and thereafter, a baking process is completed to form a wiring pattern (20). As a result, the curling of an edge formed in the wiring pattern (20) can be remarkably reduced.

  • Publication number: 20050189867
    Abstract: A covering layer for insulating between column wirings and device electrodes is formed in a region including each cross point of the column wirings and row wirings and under the column wirings. Thus, when an electron source plate in which a large number of electron-emitting devices are wired in passive matrix is formed, a defect resulting from an interaction between the device electrodes and the column wirings at the time of wiring formation is reduced to improve insulation reliability. Therefore, a high quality image is obtained by a large size and higher density pixel arrangement in an image-forming apparatus using the electron source plate.

  • Patent number: 6758712
    Abstract: The wirings on an electron source substrate are formed to intersect with each other in a matrix so as to address the electron emission devices on the substrate. First and second wirings intersect with each other on a crossing point. As such a crossing point, an insulating layer is placed between the first and second wirings. To ensure insulation, a plurality of insulating layers are laminated. According to the present invention, a wiring pattern is provided on the substrate with a conductive paste and baking the wiring pattern of the conductive paste to form the first wiring. Subsequently part of the first wiring is coated at the crossing point with an insulating paste and baking the insulating paste to form a first insulating layer. The coating thickness of the insulating layer formed adjacent to sidewalls of the crossing point is substanially equal to the height of the first wiring.
