    Abstract: Disclosed herein are methods for manufacturing a metallization stack including a plurality of electrically conductive interconnects by subtractive metal spacer based deposition, and related semiconductor devices. For example, in some embodiments, a method of forming a semiconductor device may include providing a pattern of sacrificial elements over an interconnect support layer, depositing an electrically conductive material on sidewalls of the sacrificial elements, and removing the sacrificial elements so that the remaining portions of the electrically conductive material form a pattern of electrically conductive elements which can serve as interconnects of a metallization stack of the semiconductor device.

    Abstract: Techniques herein enable integrating stack materials and multiple color materials that require no corrosive gases for etching. Techniques enable a multi-line layer for self-aligned pattern shrinking in which all layers or colors or materials can be limited to silicon-containing materials and organic materials. Such techniques enable self-aligned block integration for 5 nm back-end-of-line trench patterning with an all non-corrosive etch compatible stack for self-aligned block. Embodiments include using lines of a same material but at different heights to provided etch selectivity to one of several lines based on type of material and/or height of material and etch rate.

    Abstract: Examples herein relate to devices having substrates with selective airgap regions for mitigating defects resulting from heteroepitaxial growth of device materials. An example device may include a first semiconductor layer disposed on a substrate. The first semiconductor layer may have a window cut through a face, where etching a selective airgap region on the substrate is enabled via the window. A second semiconductor layer may be heteroepitaxially grown on the face of the first semiconductor layer so that at least a portion of the second semiconductor layer is aligned over the selective air gap region.

    Abstract: Techniques disclosed herein provide a method and fabrication structure for pitch reduction for creating high-resolution features and also for cutting on pitch of sub-resolution features. Techniques include using multiple materials having different etch characteristics to selectively etch features and create cuts or blocks where specified. A hardmask is positioned first on an underlying layer or layers to be etched. A pattern of alternating materials is formed on the hardmask. One or more of the alternating materials can be preferentially removed relative to other materials to uncover a portion of the hardmask layer. The hardmask and the remaining lines of alternating material together form a combined etch mask defining sub-resolution features.
