Abstract

Systems for processing microelectronic substrates in a process chamber that incorporate improved technology for transitioning from a wet process to a dry process (especially transitioning from rinsing to drying). At least a portion of residual liquid remaining in fluid supply lines after a wet treatment is removed via a pathway that avoids purging directly onto the substrates. Related methods are also included in the present invention.
