Abstract:
1. A method of operating a gas phase growth system, the system having a reaction chamber, a vaporizer adapted to vaporize an organometallic complex, and a gas line connecting the vaporizer to the reaction chamber, said method comprising the steps of: a) evacuating the reaction chamber and the vaporizer b) supplying a stabilizer in a gaseous state into the vaporizer, thereby establishing an atmosphere of the stabilizer in the vaporizer, the gas line, and the reaction chamber, said stabilizer being capable of stabilizing the organometallic complex; c) stopping supplying the stabilizer into the vaporizer; d) discharging the stabilizer from the vaporizer, the gas line and the reaction chamber; e) loading a substrate into the reaction chamber, and heating the substrate in the reaction chamber; f) supplying an organometallic complex into the vaporizer, spraying the organometallic complex into a vaporizing chamber of the vaporizer, and vaporizing the organometallic complex in the vaporization chamber so as to obtain a vaporized organometallic complex; g) supplying the vaporized organometallic complex into the reaction chamber through the gas line, without supplying the stabilizer into the reaction chamber; h) forming a metallic layer on the heated substrate by the vaporized organometallic complex; i) stopping supplying the organometallic complex into the vaporizer; j) supplying the stabilizer in a gaseous state into the vaporizer, thereby establishing an atmosphere of the stabilizer in the vaporizer, the gas line, and the reaction chamber; and k) discharging the stabilizer from the vaporizer, the gas line, and the reaction chamber.
