    摘要: Disclosed are methods for fabricating semiconductor devices incorporating a composite trench isolation structure comprising a first oxide pattern, a SOG pattern and a second oxide pattern wherein the oxide patterns enclose the SOG pattern. The methods include the deposition of a first oxide layer and a SOG layer to fill recessed trench regions formed in the substrate. The first oxide layer and the SOG layer are then subjected to a planarization sequence including a CMP process followed by an etchback process to form a composite structure having a substantially flat upper surface that exposes both the oxide and the SOG material. The second oxide layer is then applied and subjected to a similar CMP/etchback sequence to obtain a composite structure having an upper surface that is recessed relative to a plane defined by the surfaces of adjacent active regions.

    摘要: A semiconductor device having a trench isolation region and methods of fabricating the same are provided. The method includes forming a first trench region in a substrate, and a second trench region having a larger width than the first trench region in the substrate. A lower material layer may fill the first and second trench regions. The lower material layer may be etched by a first etching process to form a first preliminary lower material layer pattern remaining in the first trench region and form a second preliminary lower material layer pattern that remains in the second trench region. An upper surface of the second preliminary lower material layer pattern may be at a different height than the first preliminary lower material layer pattern. The first and second preliminary lower material layer patterns may be etched by a second etching process to form first and second lower material layer patterns having top surfaces at substantially the same height. First and second upper material layer patterns may be formed on the first and second lower material layer patterns, respectively.

    摘要: Provided are methods of fabricating flash memory devices that may prevent a short circuit from occurring between cell gate lines. Methods of fabricating such flash memory devices may include forming gate lines including a series of multiple cell gate lines and multiple selection gate lines. Each gate line may include a stacked structure of a tunnel insulating layer, a floating gate, a gate insulating layer, and/or a polysilicon layer operable to be a control gate, all formed on a semiconductor substrate. Methods may include forming a first insulating layer that selectively fills gaps between the cell gate lines from the bottom up and between adjacent ones of the cell gate lines and the selection gate lines, and does not fill a space located on outer sides of the selection gate lines that are opposite the plurality of cell gate lines. A spacer may be formed on the outer sides of the selection gate lines that are opposite to the cell gate lines, after forming the first insulating layer. A second insulating layer may be formed in a space where the spacer is formed.

    摘要: In a method of manufacturing a non-volatile semiconductor device, a mask structure is formed on a substrate. A trench is formed by partially etching the substrate using the mask structure. A preliminary isolation layer pattern is formed on the substrate to fill the trench. The preliminary isolation layer has an upper face lower than that of the mask structure. A capping layer pattern is formed on the preliminary isolation layer pattern. An opening and an isolation layer pattern are formed by removing the mask structure and a portion on a sidewall of the preliminary isolation layer pattern adjacent to the mask structure. After forming a tunnel oxide layer, a floating gate is formed on the tunnel oxide layer and a sidewall of the isolation layer pattern.
