Abstract
A chemical vapor deposition method for forming a deposited film on a substrate using a film-forming liquid raw material in which said film-forming liquid raw material is pulverizing into liquid fine particles and said liquid fine particles are heated together with a gas to produce a film-forming raw material gas; said film-forming raw material gas is introduced into a reaction chamber; and said film-forming raw material gas is chemically reacted with a surface of a substrate disposed in said reaction chamber. A chemical vapor deposition apparatus suitable for practicing said chemical vapor deposition method, characterized by a liquid pulverizing mechanism capable of pulverizing a film-forming liquid raw material into liquid fine particles while precisely adjusting the amount of the film-forming liquid raw material to be supplied thereinto and a liquid gasifying mechanism capable of efficiently gasifying the liquid fine particles to produce a film-forming raw material gas into a reaction chamber in which a deposited film is to be formed on a substrate.
