    摘要： Disclosed is a vaporizer constituted of a dispersing section 8 and a vaporizing section 22. The dispersing section 8 comprises a gas introduction port 4 for introducing a carrier gas 3 under pressure into a gas passage, means for feeding raw material solutions 5a and 5b to the gas passage, and a gas outlet 7 for delivering the carrier gas containing the raw material solutions to the vaporizing section 22. The vaporizing section 22 comprises a vaporizing tube 20 having one end connected to a reaction tube of the MOCVD system and having the other end connected to the gas outlet 7 of the dispersing section 8, and heating means for heating the vaporizing tube 20. The vaporizing section 22 serves to heat and vaporize the raw material solution containing carrier gas 3 delivered from the dispersing section 8. The dispersing section 8 includes a dispersing section body 1 having a cylindrical hollow portion, and a rod 10 having an outer diameter smaller than the inner diameter of the cylindrical hollow portion. The rod 10 has a spiral groove 60 formed in the external periphery closer to the vaporizing section 22, the rod i0 being inserted into the cylindrical hollow portion.

    摘要： Because an evaporating apparatus for use in an MOCVD film deposition system has a structure in which a plurality of gas passages brings in a gas from the upper direction, the apparatus has a difficulty to position a jet nozzle, and the apparatus is incapable of accurately controlling the pressure and flow rate of a carrier gas mixed with a raw material solution to be issued into an evaporating unit, and it is thus difficult to highly accurately control the composition of MOCVD films. A plurality of gas passages is arranged on a flat, disk-shaped plate. With this configuration, the accurate positioning of the jet nozzle can be made easier, and the composition of MOCVD films can be controlled highly accurately.
