    摘要: Methods of forming patterns of a semiconductor device are provided. The methods may include forming a hard mask film on a semiconductor substrate. The methods may include forming first and second sacrificial film patterns that are spaced apart from each other on the hard mask film. The methods may include forming a first spacer on opposing sidewalls of the first sacrificial film pattern and a second spacer on opposing sidewalls of the second sacrificial film pattern. The methods may include removing the first and second sacrificial film patterns. The methods may include trimming the second spacer such that a line width of the second spacer becomes smaller than a line width of the first spacer. The methods may include forming first and second hard mask film patterns by etching the hard mask film using the first spacer and the trimmed second spacer as an etch mask.

    摘要: A fabricating method of a semiconductor device includes providing a substrate having a first region and a second region, forming a plurality of first gates in the first region of the substrate, such that the first gates are spaced apart from each other at a first pitch, forming a plurality of second gates in the second region of the substrate, such that the second gates are spaced apart from each other at a second pitch different from the first pitch, implanting an etch rate adjusting dopant into the second region to form implanted regions, while blocking the first region, forming a first trench by etching the first region between the plurality of first gates, and forming a second trench by etching the second region between the plurality of second gates.

    摘要: A method of manufacturing a wiring includes sequentially forming a first insulation layer, a first layer, and a second layer on a substrate, etching an upper portion of the second layer a plurality of times to form a second layer pattern including a first recess having a shape of a staircase, etching a portion of the second layer pattern and a portion of the first layer under the first recess to form a first layer pattern including a second recess having a shape of a staircase similar to the first recess, etching a portion of the first layer pattern under the second recess to form a first opening exposing a portion of a top surface of the first insulation layer, etching the exposed portion of the first insulation layer to form a second opening through the first insulation layer, and forming a wiring filling the second opening.
