Abstract: Embodiments of the present disclosure may be used for patterning a layer in a 5 nm node or beyond fabrication to achieve an end-to-end distance below 35 nm. Compared to the state of the art technology, embodiments of the present disclosure reduce cycle time and cost of production from three lithographic processes and four etching processes to one lithographic process and three etch processes.

Abstract: A system and method for forming a phase change memory material on a substrate, in which the substrate is contacted with precursors for a phase change memory chalcogenide alloy under conditions producing deposition of the chalcogenide alloy on the substrate, at temperature below 350° C., with the contacting being carried out via chemical vapor deposition or atomic layer deposition. Various tellurium, germanium and germanium-tellurium precursors are described, which are useful for forming GST phase change memory films on substrates.

Abstract: After a gate oxide film 10 has been formed on a silicon substrate G, a first step of forming a microcrystalline silicon film by high electron density plasma of an electron temperature of 2.0 eV or less and a second step of forming an ultra-microcrystalline silicon film by high electron density plasma of an electron temperature higher than 2.0 eV are repeated. A stacked-layer film 20 of the ultra-microcrystalline silicon film and the microcrystalline silicon film is thereby formed. With the film formation method described above, at least one of an n-channel thin-film transistor and a p-channel thin-film transistor with the stacked-layer film 20 functioned as an active layer may be manufactured.
