摘要： The present invention provides a method of eliminating or covering a defect source in a wafer edge region for semiconductor fabrication. During the etching process of a sacrificial oxide layer for storage node openings, the sacrificial oxide layer has a rumple topology in the wafer edge region due to etching non-uniformity of a photoresist layer formed on the sacrificial oxide layer. Subsequent deposition of a conductive layer and planarization etching, the conductive layer undesirably remains at the wafer edge region as a defect source. Such conductive contaminant particles dislodge, causing many problems in the wafer main region. The present invention removes such a defect source via two methods. One is to directly remove the defect source using a photoresist pattern exposing thereof. The other is to fix the defect source in place in the wafer edge region by protecting thereof by a photoresist pattern during subsequent cleaning processes.

摘要： Disclosed herein are a semiconductor device and a method of manufacturing the same that increases the reliability of these devices as size design limitations decrease. Generally, a first insulating film, and wiring, including conductive film patterns and second insulating film patterns are formed on a substrate. Third insulating film patterns including a silicon-oxide-based material are formed on sidewalls of the wiring, and contact patterns and spacers on the sidewalls thereof for defining contact hole regions are formed on the wiring. The contact holes contact surfaces of the third insulating film patterns and pass through the first insulating film. Thus, the thickness of a second insulating film pattern used in the wiring can be minimized, thereby increasing a gap-fill margin between the wiring. A parasitic capacitance between the wiring can be reduced because silicon oxide spacers with a low dielectric constant are formed on sidewalls of the wiring.
摘要翻译：本文公开了一种半导体器件及其制造方法，其随着尺寸设计限制的降低而增加这些器件的可靠性。通常，在基板上形成包括导电膜图案和第二绝缘膜图案的第一绝缘膜和布线。在布线的侧壁上形成包括基于氧化硅的材料的第三绝缘膜图案，并且在布线上形成用于限定接触孔区域的侧壁上的接触图形和间隔物。接触孔接触第三绝缘膜图案的表面并穿过第一绝缘膜。因此，可以使布线中使用的第二绝缘膜图案的厚度最小化，从而增加布线之间的间隙填充余量。由于在布线的侧壁上形成具有低介电常数的氧化硅间隔物，所以布线之间的寄生电容可以减小。

摘要： Embodiments of methods of fabricating protected contact plugs include forming an electrically insulating layer having a contact hole therein, on a semiconductor substrate and then forming an electrically conductive lower barrier layer that lines at least an upper portion of a sidewall of the contact hole. This lower barrier layer may comprise titanium nitride (TiN). A step is also performed to form an electrically conductive contact plug that extends in the contact hole, is electrically coupled to the lower barrier layer and protrudes above the electrically insulating layer. The contact plug may comprise tungsten (W). An electrically conductive upper barrier layer is then formed that extends on a protruded upper surface of the contact plug and on a surface of the lower barrier layer. A step may then be performed to pattern the upper barrier layer to define an electrically conductive barrier spacer that extends on a sidewall or end of the lower barrier layer and define an upper barrier layer cap on the protruded upper surface of the contact plug.

摘要： A method of forming self-aligned contacts in a semiconductor device wherein a silicon nitride layer and a polysilicon layer are formed on a gate electrode layer. The polysilicon layer, the silicon nitride layer, and the gate electrode layer are etched to form gate electrode configurations. Sidewall spacers are formed on both sidewalls of the gate electrode configurations. An oxide layer is then deposited on the resulting structure. Selected portions of the oxide layer are etched to form self-aligned contacts that expose the semiconductor substrate. Because the polysilicon has an excellent etch selectivity with respect to the oxide layer, the gate electrode layer can be sufficiently protected during the etching of the oxide layer resulting in a good shoulder margin at the exposed upper edges of the silicon nitride gate mask layer.

摘要： Integrated circuit contact holes may be formed on an integrated circuit substrate, by providing a first conductive pattern on the substrate, a first interlayer insulating film on the first conductive pattern, a second conductive pattern on the first interlayer insulating film and a second interlayer insulating film on the second conductive pattern. A blocking layer pattern is formed on the second interlayer insulating film. The blocking layer pattern overlies, is of the same pattern as, and is as least as wide as the second conductive pattern. The first and second interlayer insulating films are then selectively etched relative to the blocking layer pattern and the second conductive pattern, to form contact holes that expose the first conductive pattern. A photoresist pattern may also be formed on a portion of the blocking layer pattern. Then, the first and second interlayer insulating films are selectively etched relative to the photoresist pattern, the blocking layer pattern and the second conductive pattern, to form contact holes that expose the first conductive pattern. The above-described integrated circuit contact hole forming methods may also be used to form integrated circuit contact holes for integrated circuit memory devices. For integrated circuit memory devices, the first conductive pattern may correspond to pad electrodes, the second conductive pattern may correspond to bit lines, and capacitor contact plugs may be formed in the contact holes.
