  • Patent number: 10804821
    Abstract: An apparatus and a method for monitoring the relative relationship between the wafer and the chuck is provided, especially for monitoring whether the wafer is sticky on the chuck when the wafer is de-chucked. The lift pins may be extended outside the chuck to separate the wafer and the chuck when the wafer is de-chucked. By detecting the capacitance between the de-chucked wafer and the chuck, especially by comparing the detected capacitance with the capacitance that the wafer is held by the chuck, one may determine whether the wafer is sticky on the chuck, or even whether the wafer is properly supported by the lift pins. Accordingly, an early alarm may be issued if the wafer is sticky or improperly removed. Besides, by controlling a switch electrically connected to a lift pin that contacted the wafer, the charges at the wafer may be eliminated.

  • Patent number: 10775455
    Abstract: In a superconducting magnet arrangement, such as used in a magnetic resonance system, and a power management method therefor, an enhanced economic power mode (EPM) is implemented wherein the compressor operation is controlled by magnet pressure, temperature and time, so as to ensure the readiness of the magnet system for a scanning operation upon exiting the enhanced EPM. A processor implementing the enhanced EPM looks for a signal that indicates that the magnet system is operational and, in the absence of that signal for a predetermined period of time, enters into EPM. Exit from EPM occurs if certain conditions are violated, but then re-entry into EPM is attempted (re-starting EPM), thereby making the magnet system ready for operation again, if and when a patient scan is to be implemented.
