The cleaning method according to an embodiment of the present invention is for cleaning a plasma processing apparatus that performs a plasma processing on a substrate. This cleaning method includes: forming a protective film; and cleaning. The forming the protective film involves forming the protective film in a plasma generation region by generating plasma while supplying a film-forming gas into a processing container in which a processing space including the plasma generation region and a diffusion region is formed. The cleaning involves cleaning an interior of the processing container in which the protective film has been formed by generating plasma while supplying a cleaning gas into the processing container.

Cleaning method and plasma treatment device

A film forming method of forming a film on a substrate by using a film forming apparatus including a processing container, and a stage provided in an interior of the processing container to place the substrate thereon and in which aluminum is contained, includes: forming a film continuously on one substrate or on a plurality of substrates by supplying a gas for film formation to the interior of the processing container while heating the substrate placed on the stage; cleaning the interior of the processing container with a fluorine-containing gas in a state in which the substrate is unloaded from the processing container; and performing a post-process by generating plasma of an oxygen- and hydrogen-containing-gas in the interior of the processing container, wherein the forming the film, the cleaning the interior of the processing container, and the performing the post-process are repeatedly performed.

Film forming method and film forming apparatus

A film forming method includes: placing a substrate on which a pattern, which includes a plurality of convex and concave portions, is formed on a stage disposed inside a chamber; and selectively forming a silicon-containing film on the plurality of convex portions of the pattern by applying a bias power to the stage and introducing microwaves into the chamber while supplying a processing gas containing a silicon-containing gas and a nitrogen-containing gas into the chamber to generate plasma, wherein the selectively forming the silicon-containing film includes a first film formation of forming a silicon-containing film around upper sides of the plurality of convex portions and a second film formation of forming a silicon-containing film on upper portions of the plurality of convex portions.

In a nickel film forming method, an initial Ni film is formed on a substrate by a chemical vapor deposition (CVD) process by using a nickel-containing compound having a molecular structure in which a ligand containing a nitrogen-carbon bond is included and nitrogen of the ligand coordinates with nickel as a film forming source material and at least one selected from ammonia, hydrazine, and derivatives thereof as a reduction gas. Further, a main Ni film is formed on the initial Ni film by CVD by using the nickel-containing compound as the film forming source material and hydrogen gas as the reduction gas.
