摘要:
Methods for the production of silicon nitride films by vapor-phase growth. A hydrazine gas and at least one precursor gas are fed into a reaction chamber containing a substrate. The precursor gas is either a trisilylamine gas or a silylhydrazine gas. A silicone nitride film is formed through the reaction of the hydrazine gas and the precursor gas.

Method for producing a metal silicon (oxy)nitride by introducing a carbon-free silicon source (for example, (SiH3)3N), a metal precursor with the general formula MXn (for example, Hf(NEt2)4), and an oxidizing agent (for example, O2) into a CVD chamber and reacting same at the surface of a substrate. MsiN, MSIo and/or MSiON films may be obtained. These films are useful are useful as high k dielectrics films.
摘要:
To provide an efficient method for cleaning film-forming apparatuses in order to remove a ruthenium-type deposit residing on a constituent member of a film-forming apparatus after said apparatus has been used to form a film comprising ruthenium or solid ruthenium oxide, wherein at least the surface region of the ruthenium-type deposit comprises solid ruthenium oxide.A ruthenium-type deposit, at least the surface region of which is solid ruthenium oxide, is brought into contact with reducing gas that contains a reducing species comprising hydrogen or hydrogen radical and the solid ruthenium oxide is thereby converted into ruthenium metal. This ruthenium metal is subsequently converted into volatile ruthenium oxide by bringing the ruthenium metal into contact with an oxidizing gas that contains an oxidizing species comprising an oxygenated compound, and this volatile ruthenium oxide is removed from the film-forming apparatus.
