摘要： A method and system for sterilizing an article is provided that includes use of a low frequency (LF) gas discharge plasma. The method includes placing the article in a vacuum chamber and evacuating the vacuum chamber to a predetermined pressure. Gas or vapor species are introduced into the vacuum chamber, and a low frequency plasma is generated within the vacuum chamber, the low frequency plasma having a frequency of from 0 to approximately 200 kHz. The low frequency plasma is maintained for a time period sufficient to substantially remove gas or vapor species from the article. The sterilization system includes a vacuum chamber coupled to a vacuum pump and a vent, a first electrode, and a second electrode. The sterilization system further includes a first region within the vacuum chamber, the first region including a region between the first and second electrodes, and a second region within the vacuum chamber, the second region being in fluid communication with the first region. The sterilization system further includes a source of reactive agent species coupled to the vacuum chamber, a process control monitor, and a low frequency power module including components adapted to apply a low frequency voltage between the first electrode and second electrode to generate a low frequency plasma in the vacuum chamber, the low frequency voltage having a frequency of from 0 to approximately 200 kHz.

摘要： An embodiment of the present invention is a technique to automate transfer of parts for high throughput. A boat transfer unit (BTU) arm carrying a boat containing a plurality of parts is rotated from an initial position to a first position that is below a process chamber. The BTU arm engages a boat support that supports the boat. The BTU arm is moved upward to a second position such that the boat partially enters the process chamber at a distance D with respect to an entrance opening of the process chamber. An elevator arm carrying a pedestal is engaged to lower side of the boat support. The BTU arm is moved away from the second position. The elevator arm is moved upward to fully insert the boat inside the process chamber.
