    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: In a method of forming a device isolation layer, a trench is formed in a substrate and a preliminary fin is formed on the substrate using a hard mask pattern on a surface of the substrate as an etching mask. A first thin layer is formed on the bottom and sides of the trench. A lower insulation pattern is formed in a lower portion of the trench on the first thin layer, and an upper insulation pattern is formed on the lower insulation pattern. The upper insulation pattern is etched away so that the first thin layer remains on a side surface of the preliminary fin. A device isolation layer is formed in the lower portion of the trench and a silicon fin is formed having a top surface thereof that is higher relative to a top surface of the device isolation layer.

    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.
