摘要:
Antimony, germanium and tellurium precursors useful for CVD/ALD of corresponding metal-containing thin films are described, along with compositions including such precursors, methods of making such precursors, and films and microelectronic device products manufactured using such precursors, as well as corresponding manufacturing methods. The precursors of the invention are useful for forming germanium-antimony-tellurium (GST) films and microelectronic device products, such as phase change memory devices, including such films.
摘要:
A multi-step method for depositing ruthenium thin films having high conductivity and superior adherence to the substrate is described. The method includes the deposition of a ruthenium nucleation layer followed by the deposition of a highly conductive ruthenium upper layer. Both layers are deposited using chemical vapor deposition (CVD) employing low deposition rates.

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.

A CVD Method of forming gate dielectric thin films on a substrate using metalloamide compounds of the formula M(NR1R2)x, or wherein M is Zr, Hf, Y, La, Lanthanide series elements, Ta, Ti, or Al; N is nitrogen; each of R1 and R2 is same or different and is independently selected from H, aryl, perfluoroaryl, C1-C8 alkyl, C1-C8 perfluoroalkyl, alkylsilyl; and x is the oxidation state on metal M; and an aminosilane compound of the formula HxSiAy(NR1R2)4-x-y or wherein H is hydrogen; x is from 0 to 3; Si is silicon; A is a halogen; Y is from 0 to 3; N is nitrogen; each of R1 and R2 is same or different and is independently selected from the group consisting of H, aryl, perfluoroaryl, C1-C8 alkyl, and C1-C8 perfluoroalkyl; and n is from 1-6. By comparison with the standard SiO2 gate dielectric materials, these gate dielectric materials provide low levels of carbon and halide impurity.
