  • Publication number: 20070047304
    Abstract: In a non-volatile memory device having a relatively high operation performance and a method of manufacturing the same, a substrate may be prepared to include an active region on which a conductive structure is located and defined by a field region in which an isolation layer is formed. A tunnel oxide layer may be formed on the active region of the substrate. A floating gate pattern may be formed on the tunnel oxide layer, and may include a lower part having a first width that is formed on the tunnel oxide layer and an upper part having a second width that is formed on the lower part, where the second width is substantially smaller than the first width. A dielectric layer pattern may be formed on the floating gate pattern, and a control gate pattern may be formed on the dielectric layer pattern. Accordingly, the non-volatile memory device may have an improved efficiency in programming and erasing data.

  • Patent number: 6086443
    Abstract: Liquid crystal displays are manufactured by securing overlying first and second substrates with an intermediate sealant together such that they form a cell cavity with an injection opening. In one embodiment, a plurality of over-sized spacers are disposed intermediate the first and second substrates in the cell cavity. The first and second substrates are structurally secured by heat compressing the layers together with a pressure in the range of about 0.4-0.55 kg/cm.sup.2. A quantity of liquid crystal material is injected into the cell cavity through the injection opening to expand the substrate layers to a non-planar configuration. A second sealant is applied proximate to the injection opening and a second compressing step is used to facilitate the proper positioning of the second sealant into injection opening. The second compressing step employs a pressure about 0.1-1.0 kg/cm.sup.2 greater than the pressure in the first compressing step.
