摘要： It is aimed at providing a vaporization apparatus and a vaporization method capable of keeping track of a progressive condition of clogging of the apparatus. It is also aimed at providing a vaporization apparatus and a vaporization method capable of eliminating clogging prior to occurrence of complete clogging, without disassembling the apparatus. It provides a vaporization apparatus for introducing a carrier gas from one end of a gas passage and for feeding, the carrier gas including a material solution, from the other end of the gas passage to a vaporization part to thereby vaporize the material solution, characterized in that a mass flow controller (MFC) is provided at the one end of the gas passage, and means for detecting a pressure within the gas passage is provided. The vaporization apparatus is characterized in that the same is provided with means for introducing a chemical solution capable of dissolving therein matters deposited or sticked to the inside of the gas passage, into the gas passage.

摘要： There is obtained an MOCVD oriented vaporizer which eliminates a phenomenon that thin-film materials are adhered to a portion of the vaporizer near and around a spout thereof. A carrier gas/small amount oxidizing gas supply part supplies a carrier gas, which is supplied through an internally formed gas passage and which contains a material solution, to a vaporization part; a bubble prevention/material solution supply part supplies a material for preventing generation of bubbles of the carrier gas containing the material solution, and the material solution, into the carrier gas; a solvent vaporization restricting/cooling system restricts vaporization of a solvent; and a swirl flow preventing gas supply part supplies a gas for preventing occurrence of swirl flows near a gas outlet of the vaporization part. An atomizing part causes the carrier gas, which contains the material solution and which is ejected from the vaporizer, to be formed into a finely atomized state; and a complete vaporization oriented high performance vaporization tube completely vaporizes the carrier gas ejected from the vaporizer and containing the material solution. This enables long-term usage without clogging and the like, and enables a stable material supply to a reaction part.
