    摘要: A method of filling a trench in a substrate ensures that a void or seam is not left in the material occupying the trench. First, a preliminary insulating layer is formed so as to extend contiguously along the bottom and sides of the trench and along an upper surface of the substrate. Impurities are then implanted into a portion of the preliminary insulating layer adjacent the top of the first trench to form a first insulating layer having a doped region and an undoped region. The doped region is removed to form a first insulating layer pattern at the bottom and sides of the first trench, and which first insulating layer pattern defines a second trench. The second trench is then filled with insulating material.

    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: 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.
