Abstract
A gas feeding device for feeding to a reaction vessel a starting gas for film formation by chemical vapor deposition. The gas feeding device is connected to a container which contains an organometallic compound, and has a plurality of gas introducing openings for introducing a carrier gas into the container for carrying vaporized organometallic compound into the reaction vessel. The gas feeding device includes an accelerating device which selects a carrier gas introducing route into the container through at least one of the plurality of gas introducing openings for accelerating the generation of the starting gas.
