    摘要: A method and apparatus for performing ALD deposition of hafnium oxide on a substrate is provided. The apparatus includes a process chamber, a precursor delivery subsystem, an oxidizer delivery subsystem, a purge gas subsystem, a solvent flush subsystem, and optional solvent recovery and purification subsystems. The method includes pulsing precursor compounds into the process chamber in sequence. While one precursor is pulsed, purge gas is provided through the other precursor line. After pulsing, precursor lines are purged, and the chamber is evacuated and purged. A solvent flush step is employed to remove precursor deposits that build up in piping over time.
