摘要： Embodiments of the present invention are directed to reducing clogging of nozzles and to reducing flow variance through the nozzles in a semiconductor processing chamber. In one embodiment, a method of introducing a gas into a semiconductor processing chamber comprises providing a nozzle having a proximal portion connected to a chamber wall or a gas distribution ring of the semiconductor processing chamber and a distal portion oriented inwardly away from the chamber wall into an interior of the semiconductor processing chamber. The nozzle includes a proximal end coupled with a gas supply. The nozzle includes a nozzle opening at a distal end. The nozzle includes a nozzle passage extending from the proximal end to the distal end. The method further comprises flowing a gas from the gas supply through the proximal end, the nozzle passage, and the nozzle opening of the nozzle into the interior of the semiconductor processing chamber; and choking the gas flow through the nozzle passage at a choke location which is spaced away from the distal end.

摘要： A valve control system for a semiconductor processing chamber includes a system control computer and a plurality of electrically controlled valves associated with the processing chamber. The system further includes a programmable logic controller in communication with the system control computer and operatively coupled to the electrically controlled valves. The refresh time for control of the valves may be less than 10 milliseconds. Consequently, valve control operations do not significantly extend the period of time required for highly repetitive cycling in atomic layer deposition processes. A hardware interlock may be implemented through the output power supply of the programmable logic controller.
