  • Patent number: 8367535
    Abstract: Example embodiments herein relate to a method of fabricating a semiconductor device. The method may include forming a liner insulating layer on a surface of a gate pattern to have a first thickness. Subsequently, a gap fill layer may be formed on the liner insulating layer by flowable chemical vapor deposition (FCVD) or spin-on-glass (SOG). The liner insulating layer and the gap fill layer may be recessed such that the liner insulating layer has a second thickness, which is smaller than the first thickness, in the region in which a metal silicide will be formed. Metal silicide may be formed on the plurality of gate patterns to have a relatively uniform thickness using the difference in thickness of the liner insulating layer.

  • Patent number: 8043914
    Abstract: 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.

  • Patent number: 7674685
    Abstract: 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.
