    摘要: A method of fabricating a semiconductor device including a fin field effect transistor (Fin-FET) includes forming sacrificial bars on a semiconductor substrate, patterning the sacrificial bars to form sacrificial islands on the semiconductor substrate, forming a device isolation layer to fill a space between the sacrificial islands, selectively removing the sacrificial islands to expose the semiconductor substrate below the sacrificial islands, and anisotropically etching the exposed semiconductor substrate using the device isolation layer as an etch mask to form a recessed channel region. The recessed channel region allows the channel width and channel length of a transistor to be increased, thereby reducing the occurrence of short channel effects and narrow channel effects in highly integrated semiconductor devices.

    摘要: A non-volatile memory device for 2-bit operation and a method of fabricating the same are provided. The non-volatile memory device includes an active region and a gate extending in a word line direction on a semiconductor substrate, and crossing each other repeatedly; a charge storage layer disposed below the gate, and confined at a portion where the gate and the active region cross; a charge blocking layer formed on the charge storage layer; a tunnel dielectric layer formed below the charge storage layer; first and second source/drain regions formed in the active region exposed by the gate; and first and second bit lines crossing the word line direction. The active region may be formed in a first zigzag pattern and/or the gate may be formed in a second zigzag pattern in symmetry with the first zigzag pattern.

    摘要: A method and mask having balance patterns for reducing and/or preventing chemical flare from occurring in a photoresist between a first mask region and a second mask region. Balance patterns formed on the mask may have a desired and/or predetermined pitch and may be regularly arranged. If the pitch of the balance patterns is equal to or smaller than a threshold value, the balance patterns may not allow the patterns to be transferred onto a photoresist. In addition, the photoresist corresponding to the balance patterns may be either completely removed or completely remain depending on the duty of the balance patterns.

    摘要: In a thin layer structure and a method of forming the same, a first preliminary insulation pattern is formed on a substrate and includes a first opening exposing the substrate. One or more preliminary seed patterns including single crystalline silicon are formed in the first opening. A second insulation layer is formed on the first preliminary insulation pattern and the one or more preliminary seed patterns. A second insulation pattern, a first insulation pattern and one or more seed patterns are formed by etching the first and second insulation layers and the one or more preliminary seed patterns. The second insulation pattern includes a second opening having a flat bottom portion. A single crystalline silicon pattern is formed in the second opening, wherein a central thickness of the single crystalline silicon pattern is substantially identical to a peripheral thickness thereof, thereby reducing or preventing a thinning defect in a semiconductor device.
