摘要： A method for manufacturing a semiconductor device includes providing a patterned hard- mask layer (41). The hard-mask layer (41) is provided on an exposed surface (16) of one or more layers to be patterned of a semiconductor intermediate product (1).

摘要： An interconnect structure on a substrate is provided. The interconnect structure comprises electrically conductive interconnect elements on at least two interconnect levels on or above a substrate level. In the interconnect structure of the invention, at least one electrically conductive via connects a first interconnect element on one interconnect level or on the substrate level to a second interconnect element on a different interconnect level. The via extends in a via opening of a first dielectric layer and comprises an electrically conductive via material that contains electrically conductive cylindrical carbon nanostructures. At least one cover-layer segment reaches into a lateral extension of the via opening and defines a via aperture that is small enough to prevent a penetration of the carbon nanostructures through the via aperture. This structure enhances control of carbon nanostructure growth in a height direction during fabrication of the interconnect structure.

摘要： The present invention relates to an integrated-circuit device that has at least one Copper-containing feature in a dielectric layer, and a diffusion-barrier layer stack arranged between the feature and the dielectric layer. The integrated-circuit device of the invention has a diffusion-barrier layer stack, which comprises, in a direction from the Copper-containing feature to the dielectric layer, a CuSiN layer and a SiN layer. This layer combinat ion provides an efficient barrier for suppressing Copper diffusion from the feature into the dielectric layer. Furthermore, a CuSiN/SiN layer sequence provides an improved adhesion between the layers of the diffusion-barrier layer stack and the dielectric layer, and thus improves the electromigration performance of the integrated-circuit device during operation. Therefore, the reliability of device operation and the lifetime of the integrate- circuit device are improved in comparison with prior-art devices. The invention further relates to a method for fabricating such an integrated-circuit device.

摘要： The present invention relates to a method for fabricating at least one feature, which has a target lateral width, in a substrate layer. The method allows fabricating a feature with a target lateral width in a substrate layer that is smaller than can be obtained with the used lithographic equipment. In comparison with known methods, it provides an increased resistance to temperatures typically used during processing, in particular, during a plasma etching step. The increased temperature resistance is achieved by using a layer structure that comprises an amorphous carbon layer on the substrate layer, a capping layer on the amorphous carbon layer, and a first resist layer structure on the capping layer. In this layer structure, a carbon contribution to the etching process, which is usually provided by a resist material, is provided by the amorphous carbon layer, which forms a hard mask on the substrate layer.

摘要： The invention relates to a method for selective deposition of Si or SiGe on a Si or SiGe surface. The method exploits differences in physico-chemical surface behaviour according to a difference in doping of first and second surface regions. By providing at least one first surface region with a Boron doping of a suitable concentration range and exposing the substrate surface to a cleaning and passivating ambient atmosphere in a prebake step at a temperature lower or equal than 800 °C, a subsequent deposition step of Si or SiGe will not lead to a layer deposition in the first surface region. This effect is used for selective deposition of Si or SiGe in the second surface region, which is not doped with Boron in the suitable concentration range, or doped with another dopant, or not doped. The method thus saves a usual photolithography sequence required for selective deposition of Si or SiGe in the second surface region according to the prior art.
摘要翻译：本发明涉及用于在Si或SiGe表面上选择性沉积Si或SiGe的方法。该方法根据第一和第二表面区域的掺杂差异，利用物理化学表面行为的差异。通过提供具有适当浓度范围的硼掺杂的至少一个第一表面区域并且在低于或等于800℃的温度下在预烘烤步骤中将衬底表面暴露于清洁和钝化环境气氛中，随后的沉积步骤或SiGe不会导致第一表面区域中的层沉积。该效应用于在不掺杂硼的合适浓度范围内或掺杂有另一种掺杂剂的第二表面区域中选择性沉积Si或SiGe，或不掺杂。因此，该方法节省了根据现有技术在第二表面区域中选择性沉积Si或SiGe所需的常规光刻序列。
