    摘要： Example embodiments relate to semiconductor devices having a single body crack stop structure configured to reduce or prevent crack propagation and/or moisture penetration. A semiconductor substrate according to example embodiments may include an active region and a crack stop region surrounding the active region. Interlayer insulating layers may be sequentially stacked on the semiconductor substrate. The interlayer insulating layers may include first dual damascene patterns and a first opening. The first dual damascene patterns may be formed in the interlayer insulating layers so as to be perpendicular to the surface of the semiconductor substrate while exposing a first portion of the semiconductor substrate. The first opening may be formed in the crack stop region and may extend through the interlayer insulating layers to expose a second portion of the semiconductor substrate. First dual damascene metal wirings may be formed in the first dual damascene patterns and may contact the exposed first portion of the semiconductor substrate. A single body first crack stop structure may be formed in the first opening so as to contact the exposed second portion of the semiconductor substrate.

    摘要： A method for forming a metal wiring layer in a semiconductor device using a dual damascene process is provided. A stopper layer, an interlayer insulating layer, and a hard mask layer are sequentially formed on a semiconductor substrate having a conductive layer. A first photoresist pattern that comprises a first opening having a first width is formed on the hard mask layer. The hard mask layer and portions of the interlayer insulating layer are etched using the first photoresist pattern as an etching mask, thereby forming a partial via hole having the first width. The first photoresist pattern is removed. An organic material layer is coated on the semiconductor substrate having the partial via hole is formed to fill the partial via hole with the organic material layer. A second photoresist pattern that comprises a second opening aligned with the partial via hole and having a second width greater than the first width is formed on the coated semiconductor substrate. The organic material layer and the hard mask layer on the interlayer insulating layer are etched using the second photoresist pattern as an etching mask. The second photoresist pattern and the organic material layer are simultaneously removed. A wiring region having the second width and a via hole having the first width are formed by etching the interlayer insulating layer using the hard mask layer as an etching mask.

    摘要： A method of forming an interconnection line in a semiconductor device is provided. A first etching stopper is formed on a lower conductive layer which is formed on a semiconductor substrate. A first interlayer insulating layer is formed on the first etching stopper. A second etching stopper is formed on the first interlayer insulating layer. A second interlayer insulating layer is formed on the second etching stopper. The second interlayer insulating layer, the second etching stopper, and the first interlayer insulating layer are sequentially etched using the first etching stopper as an etching stopping point to form a via hole aligned with the lower conductive layer. A protective layer is formed to protect a portion of the first etching stopper exposed at the bottom of the via hole. A portion of the second interlayer insulating layer adjacent to the via hole is etched using the second etching stopper as an etching stopping point to form a trench connected to the via hole. The protective layer is removed. The portion of the first etching stopper positioned at the bottom of the via hole is removed. An upper conductive layer that fills the via hole and the trench and is electrically connected to the lower conductive layer is formed.
