Patent number: 9953862Abstract: A plasma processing method performs an etching process of supplying a fluorine-containing gas into a plasma processing space and etching a target substrate, in which a silicon oxide film or a silicon nitride film is formed on a surface of a metal silicide film, with plasma of the fluorine-containing gas (process S101). Then, the plasma processing method performs a reduction process of supplying a hydrogen-containing gas into the plasma processing space and reducing, with plasma of the hydrogen-containing gas, a metal-containing material deposited on a member, of which a surface is arranged to face the plasma processing space, after the etching process (process S102). Thereafter, the plasma processing method performs a removal process of supplying an oxygen-containing gas into the plasma processing space and removing metal, which is obtained by reducing the metal-containing material in the reduction process, with plasma of the oxygen-containing gas (process S103).Type: GrantFiled: November 4, 2015Date of Patent: April 24, 2018Assignee: TOKYO ELECTRON LIMITEDInventors: Akitoshi Harada, Yen-Ting Lin, Chih-Hsuan Chen, Ju-Chia Hsieh, Shigeru Yoneda

Patent number: 9953866Abstract: A method is provided which includes dispensing and removing different deposition solutions during an electroless deposition process to form different sub-films of a composite layer. Another method includes forming a film by an electroless deposition process and subsequently annealing the microelectronic topography to induce diffusion of an element within the film. Yet another method includes reiterating different mechanisms of deposition growth, namely interfacial electroless reduction and chemical adsorption, from a single deposition solution to form different sub-films of a composite layer. A microelectronic topography resulting from one or more of the methods includes a film formed in contact with a structure having a bulk concentration of a first element. The film has periodic successions of regions each comprising a region with a concentration of a second element greater than a set amount and a region with a concentration of the second element less than the set amount.Type: GrantFiled: November 14, 2013Date of Patent: April 24, 2018Assignee: Lam Research CorporationInventor: Igor C.
