Abstract:
A liquid supply system comprising:a first pump for delivering a liquid under high pressure; a vaporizer for vaporizing the liquid delivered from said first pump to thereby obtain vapor, with the vapor being adapted to be introduced into a reaction chamber; a solvent supply system for supplying a solvent for cleaning or a cleaning liquid, with said solvent supply system including a second pump for delivering the solvent or the cleaning liquid under high pressure, a gas supply system for supplying a gas, with said gas supply system including a flow rate controller for controlling the flow rate of the gas; a passage for introducing the solvent or the cleaning liquid from said second pump into said first pump and said vaporizer so that said first pump and said vaporizer become filled with the solvent or the cleaning liquid; and a passage for introducing the gas from said flow rate controller into said first pump and said vaporizer such that the gas mixes with the solvent or the cleaning liquid to form gas bubbles, whereby said first pump and said vaporizer are cleaned in response to vibrations resulting from impulses due to the gas bubbles.
