Abstract: 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.

Abstract: The present invention is directed to a semiconductor device having a photodetector and a method of fabricating the same. The photodetector includes a visible ray absorbing pattern disposed on a top and/or bottom surface of an interconnection formed at a light shielding area between adjacent photodetectors, which prevents obliquely incident light from reaching an adjacent photodetector.

Abstract: The present invention can provide methods of forming a thin layer for a semiconductor device. The methods can include forming a recessed portion on an object, and forming an insulation layer on the object by reacting a water vapor, an oxygen gas including an oxygen radical and an organic silicon source gas with each other, so that the recessed portion is filled with the insulation layer. Accordingly, a flow characteristic of the insulation layer can be improved, so that a seam defect can be sufficiently decreased in the insulation layer. The present invention can further provide apparatus for forming a thin layer.

Abstract: An integrated circuit device includes a substrate that has a pair of conductive structures disposed thereon. An insulating interlayer is on the substrate between the pair of conductive structures. The insulating interlayer includes a carbon-containing silicon oxide layer on the substrate and a silicon oxide layer on the carbon-containing silicon oxide layer.

Abstract: A method of manufacturing a semiconductor device includes forming a silicon nitride layer on a semiconductor substrate on which a predetermined pattern is formed. The silicon nitride layer includes a plurality of bonds formed between silicon and nitrogen. A portion of the bonds formed between silicon and nitrogen is broken to form at least one free bonding site on a surface of the silicon nitride layer. A silane compound and a flow fill method are used to form a silicon oxide layer on the silicon nitride layer.
