Abstract:
1. A vaporizer comprising: an inlet port for introducing a precursor in a liquid phase or a gas-liquid mixture phase; a plurality of vaporizing sections arranged on a downstream side of the inlet port for vaporizing the precursor; and an outlet port for delivering the precursor vaporized by the vaporizing sections, the plurality of vaporizing sections arranged in parallel between the inlet port and the outlet port, wherein each of the vaporizing sections is of a flow channel type comprising a nozzle unshared by any other vaporizing section, for spraying the precursor, and a corresponding heating channel coupled to a downstream side of the nozzle, and wherein a wall surface that forms the nozzle is continuously connected to a wall surface that forms the corresponding heating channel, so that precursor flow through each of the respective vaporizing sections is independent of the precursor flow through any other vaporizing section.
