    摘要: A method of forming a semiconductor device includes preparing a substrate having a recessed area. A silicon oxide layer is formed at the recessed area. A catalytic nitridation treatment is performed for an upper portion of the silicon oxide layer to form a nitridation reactant on the upper portion of the silicon oxide layer. A dielectric layer is formed on the silicon oxide layer where the nitridation reactant is formed. The dielectric layer is annealed. According to the foregoing method, recession of the dielectric layer is prevented to fabricate a high-quality semiconductor device.

    摘要: Methods of forming material in a gap in a substrate include forming a pattern to define a gap on a substrate. A bottom oxide layer is formed on a surface of the substrate and substantially filling the gap. The bottom oxide layer is etched back inside an opening in the gap to expose side walls of the gap so that a residual bottom oxide layer remains at a bottom of the gap. A top oxide layer is selectively deposited on the residual bottom oxide layer, wherein the top oxide layer is deposited in a first direction toward the opening at a faster rate than in a second direction away from the side walls.

    摘要: One embodiment of a method of fabricating a flash memory device includes forming a trench mask pattern, which includes a gate insulation pattern and a charge storage pattern stacked in sequence, on a semiconductor substrate; etching the semiconductor substrate using the trench mask pattern as an etch mask to form trenches defining active regions; and sequentially forming lower and upper device isolation patterns in the trench. After sequentially forming an intergate insulation film and a control gate film on the upper device isolation pattern, the control gate film, the intergate insulation pattern and the gloating gate pattern are formed, thereby providing gate lines crossing over the active regions.
