Abstract:
A liquid delivery system, comprising:a copper liquid materials supply means for supplying copper liquid materials at room temperature to a vaporizer means via an orifice which is rotating at a constant speed; a carrier gas supply means for jetting a carrier gas kept at a temperature at which copper will be vaporized via a jet nozzle, the carrier gas causing the copper liquid materials to be supplied to said vaporizer means via said orifice in micro drops; the copper liquid materials and carrier gas mixing to form a vaporized copper steam in the vaporizer; a jet means for jetting the vaporized copper steam into a reactive chamber, the jet means including a copper steam inlet line having a heating jacket for maintaining a temperature of the vaporized copper steam, a mass flow controller for controlling a mass flow of said vaporized copper steam introduced from the copper steam inlet line, and a copper steam outlet line for transferring the vaporized copper steam from the mass flow controller to a copper steam jet whereby the vaporized copper steam is introduced into the reactive chamber, wherein the copper steam inlet line extends from the vaporizer means at an upward angle of about 40Â° to about 70Â° so that incompletely vaporized copper byproducts cannot be supplied to said reactive chamber.
