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.
