Abstract:
A film-forming method of supplying gaseous molecules, each composed of plural atoms, onto a substrate, said film-forming method comprising:providing a silicon substrate; providing a mixture of an inert gas component containing only at least one of a Kr gas end a Xe gas and a gas component containing maid gaseous molecules, the gaseous molecules containing the constituting elements of a silicon compound to be film-formed onto the substrate; generating a plasma of said mixture, to excite molecules of said inert gas, and thus, to excite said gaseous molecules through the collision between said excited molecules of said inert gas and said gaseous molecules to a quasi-stable level energy required to dissociate said gaseous molecules into their respective elements; and supplying said elements of said gaseous molecules onto said substrate.
