    摘要: A method and apparatus are provided for measuring the thickness of a test object. The apparatus includes an eddy current sensor having first and second sensor heads. The sensor heads are positioned to have a predetermined gap therebetween for passage by at least a portion of the test object through the gap. The sensor heads make measurements at given sampling locations on the test object as the test object is moved through the gap. The apparatus also includes a position sensing mechanism to determine positions of the sampling locations on the test object. The apparatus also includes an evaluation circuit in communication with the eddy current sensor and to the position sensing mechanism for determining the thickness of the test object at the sampling locations.

    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.
