摘要： A semiconductor device includes a substrate having one or more inner surfaces defining trenches that define an active pattern of the substrate, the trenches including a first trench and a second trench which have different widths, a device isolation layer on the substrate such that the device isolation layer at least partially fills the trenches, and a word line intersecting the active pattern. The device isolation layer includes a first isolation pattern covering a portion of the second trench, a second isolation pattern on the first isolation pattern and covering a remaining portion of the second trench, and a filling pattern filling the first trench under the word line. A top surface of the second isolation pattern is located at a higher level than a top surface of the filling pattern.

摘要： In a method of forming a wiring, an insulating interlayer including a low-k dielectric material is formed on a substrate. A first etching mask is formed on the insulating interlayer. A first etching process is performed using the first etching mask to form a first opening through the insulating interlayer. The first etching mask is removed. A protection pattern is formed on a bottom and a side of the first opening. A second etching mask is formed on the protection pattern and the insulating interlayer. A second etching process is performed using a second etching mask to form a second opening through the insulating interlayer. The second etching mask is removed. The protection pattern is removed. A wiring is formed in each of the first and second openings.
