摘要:
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.
摘要:
Silicon nitride film is formed on a silicon wafer mounted in a boat in an LPCVD tool by feeding a silicon source (SiH2Cl2, SiCl4, Si2Cl6, etc.) from an injector and feeding a mixed gas of monomethylamine (CH3NH2) and ammonia (NH3) as the nitrogen source from an injector. This addition of monomethylamine to the source substances for film production makes it possible to provide an improved film quality and improved leakage characteristics even at low temperatures (450-600° C.).

A composition and method of preparation, to provide silane compounds that are free of chlorine. The compounds are hexakis(monohydrocarbylamino)disilanes with general formula (I) ((R)HN)3—Si—Si—(NH(R))3 (I) wherein each R independently represents a C1 to C4 hydrocarbyl. These disilanes may be synthesized by reacting hexachlorodisilane in organic solvent with at least 6-fold moles of the monohydrocarbylamine RNH2 (wherein R is a C1 to C4 hydrocarbyl). Such compounds have excellent film-forming characteristics at low temperatures. These films, particularly in the case of silicon nitride and silicon oxynitride, also have excellent handling characteristics.
