    摘要: A semiconductor device includes an active region in a substrate, first to third gate structures crossing the active region and sequentially arranged parallel to each other, a first doped region in the active region between the first and second gate structures and having a first horizontal width and a first depth, and a second doped region in the active region between the second and third gate structures and having a second horizontal width and a second depth. The second horizontal width is larger than the first horizontal width and the second depth is shallower than the first depth. A distance between the first and second gate structures adjacent to each other is smaller than that between the second and third gate structures adjacent to each other. Related fabrication methods are also described.

    摘要: Disclosed herein is an apparatus for producing 3D sound. The apparatus includes a determination unit, a mono sound spreading unit, a stereo sound spreading unit, a selection unit, and a 3D sound accelerator. The determination unit receives a source sound file and determines whether the source sound file is mono or stereo. The mono sound spreading unit converts the source sound into pseudo-stereo sound and performs sound spreading on the pseudo-stereo sound, if the source sound is determined to be mono. The stereo sound spreading unit performs sound spreading on the source sound, if the source sound is determined to be stereo. The selection unit receives the output of the mono sound spreading unit or stereo sound spreading unit, and transfers the output to headphones if the headphone reproduction has been selected. The 3D sound accelerator receives the output from the selection unit if speaker reproduction has been selected, removes crosstalk from the output, and transfers the crosstalk-free output to speakers.

    摘要: a nonvolatile memory device Includes an active region defined in a semiconductor substrate and a control gate electrode crossing over the active region. A gate insulating layer is interposed between the control gate electrode and the active reigon. A floating gate is formed in the active region to penetrate the control gate electrode and extend to a predetermined depth into the semiconductor substrate. A tunnel insulating layer is successively interposed between the control gate electrode and the floating gate, and between the semiconductor substrate and the floating gate. The floating gate may be formed after a trench is formed by sequentially etching a control gate conductive layer and the semiconductor substrate, and a tunnel insulating layer is formed on the trench and sidewalls of the control gate conductive layer. The floating gate is formed in the trench to extend into a predetermined depth into the semiconductor substrate.

    摘要: A flash memory device including a tunnel dielectric layer, a floating gate layer, an interlayer dielectric layer and at least two mold layers formed on a semiconductor substrate and a method of manufacturing the same are provided. By sequentially patterning the layers, a first mold layer pattern and a floating gate layer pattern aligned with each other are formed. Exposed portions of side surfaces of the first mold layer pattern are selectively lateral etched, thereby forming a first mold layer second pattern having grooves in its sidewalls. A gate dielectric layer is formed on the semiconductor substrate adjacent to the floating gate layer pattern. A control gate having a width that is determined by the grooves in the second mold layer pattern is formed on the gate dielectric layer. By removing the first mold layer second pattern, spacers are formed on sidewalls of the control gate. Exposed portions of the interlayer dielectric layer and the floating gate layer pattern are selectively etched, using the spacer as an etch mask to form a floating gate having a width defined by the widths of the groove and spacer.
