Abstract:
A method of forming a particle comprises the steps of: forming a droplet containing a first material; forming a core portion by heating the droplet to thermally decompose in a reaction vessel; and forming a shell portion which coats the core portion by heating a raw material gas containing a second material which differs from the first material to thermally decompose in the reaction vessel.
Abstract:
A semiconductor device manufacturing method comprises the steps of placing a substrate to be processed on an electrostatic chuck on a substrate stand in a process chamber, and applying a negative voltage to the electrostatic chuck. After applying the negative voltage, the substrate is stuck onto the electrostatic chuck, a process gas is introduced into the process chamber, discharge plasma is generated, and the substrate is processed as predetermined.
Abstract:
A vapor-phase growth method comprising the steps of introducing a silicon-containing gas and ozone into a reaction vessel containing a sample, and introducing excited oxygen obtained by exciting an oxygen gas or an oxygen-containing gas, into the reaction vessel at the same the as, before, or after the silicon-containing gas and the ozone are introduced into the reaction vessel. The silicon-containing gas and the ozone react, forming an intermediate product which can readily condense. The intermediate product reacts with the excited oxygen, thereby forming a thin insulating film which excels in step coverage and has good insulating property.
