    摘要: 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.

    摘要: Barium, strontium, tantalum and lanthanum precursor compositions useful for atomic layer deposition (ALD) and chemical vapor deposition (CVD) of titanate thin films. The precursors have the formula M(Cp)2, wherein M is strontium, barium, tantalum or lanthanum, and Cp is cyclopentadienyl, of the formula wherein each of R1-R5 is the same as or different from one another, with each being independently selected from among hydrogen, C1-C12 alkyl, C1-C12 amino, C6-C10 aryl, C1-C12 alkoxy, C3-C6 alkylsilyl, C2-C12 alkenyl, R1R2R3NNR3, wherein R1, R2 and R3 may be the same as or different from one another and each is independently selected from hydrogen and C1-C6 alkyl, and pendant ligands including functional group(s) providing further coordination to the metal center M. The precursors of the above formula are useful to achieve uniform coating of high dielectric constant materials in the manufacture of flash memory and other microelectronic devices.
