摘要:
A systematic in-situ analysis is provided for ensuring that a uniform and accurate ion implantation dose for workpieces is being realized. Prior to implantation the system determines whether the calibration of a dose controller is within predetermined tolerance values. If the dose controller is outside of these values, the implantation process is halted so that the calibration can be remedied without further damaging any workpieces by mis-dosing.
摘要:
A Faraday sensor test system includes a Faraday sensor configured to intercept a quantity of ions incident on said Faraday sensor, a primary conductor and a test conductor coupled to said Faraday sensor, and a controller. The controller is configured to automatically provide a test current into the test conductor in response to a test condition. The controller is further configured to receive a return current from the primary conductor in response to the test current and to compare the return current to a value representative of the test current to determine a condition of a conductive path comprising the test conductor, the Faraday sensor, and the primary conductor.
