Abstract: A non-volatile memory device and a manufacturing method thereof are provided to suppress a reverse tunneling phenomenon by increasing a slant angle between a lower portion of a floating gate electrode and a semiconductor substrate. A non-volatile memory device includes a semiconductor substrate(100), a floating gate electrode(132), and a control gate electrode(150). The floating gate electrode has an acute tip at an upper portion thereof. An angle between the semiconductor substrate and the upper portion of the floating gate electrode is smaller than the angle between the semiconductor substrate and a lower portion of the floating gate electrode. The control gate electrode is insulated from the floating gate electrode and arranged to face at least a portion of the floating gate electrodes.

Abstract: A semiconductor device having metal/an insulating film/a metal capacitor and a method for forming the same are provided to prevent generation of a crack of the dielectric film pattern by reducing mechanical stress of a dielectric film pattern concentrated in an edge adjacent to a side wall of a first interlayer insulating film. A semiconductor device comprises a lower electrode(12), a first interlayer insulating film(14), a dielectric film pattern(18a), and an upper electrode(20a,22a). The lower electrode is formed on a substrate(10). The first interlayer insulating film is formed on the substrate having the lower electrode, and has an opening(16a) exposing the lower electrode. The dielectric film pattern is formed inside the opening conformally. The upper electrode is formed on the dielectric film. A side wall of the first interlayer insulating film defining the opening has a slope.

Abstract: A method for fabricating a semiconductor memory device and the semiconductor memory device fabricated by the same are provided to decrease resistance of via holes by increasing overlap margin between the via holes and a trench. A first interlayer dielectric(114), an etch stop layer and a second interlayer dielectric(118) are sequentially formed on a lower wiring(110), and then are partially etched to form via holes(132,134) exposing an upper surface of the lower wiring. A sacrificial layer(140) is formed to fill a portion of the via holes. The second interlayer dielectric formed on the via hole is etched to expand an upper portion of the via hole. After removing the sacrificial layer, a trench which is connected to the via hole is formed. An upper wiring is formed to fill the via holes and the trench.

Abstract: A MIM(Metal-Insulator-Metal) capacitor having a spacer type dielectric layer and a manufacturing method thereof are provided to reduce physical stress applied to the spacer type dielectric layer in a planarization process. A lower electrode(120) is arranged on a semiconductor substrate(105). An interlayer dielectric(125) is formed to cover the lower electrode and the semiconductor substrate and includes an opening(130) for exposing a predetermined region of the lower electrode. A spacer(135) is formed on a sidewall of the opening. The spacer includes an external sidewall contacting the sidewall of the opening and an internal sidewall facing the external sidewall. The spacer includes an inclined profile to increase a width of a space surrounded by the internal sidewall in an upper direction. A dielectric layer(140) is formed to cover the internal sidewall of the spacer and an upper surface of the lower electrode. An upper electrode(150) is formed to cover the dielectric layer.
