    Abstract: Disclosed is a method for focus measurement of a lithographic process. The method comprises receiving a substrate on which a metrology pattern has been printed with a lithographic apparatus with an illumination pupil, illuminating the metrology pattern with a metrology tool to measure a signal based on radiation scattered by the metrology pattern, and determining or monitoring a focus of the lithographic process based on the measured signal. Position of at least part of the metrology pattern is focus dependent. At least part of the metrology pattern has been printed by the lithography apparatus with an angular asymmetric illumination pupil.

  • Patent number: 11711023
    Abstract: A control circuit for an isolated power converter includes a first sensing circuit that senses a secondary side output voltage and produces a pulse wave modulation (PWM) signal having a duty cycle that is proportional to a value of the secondary side output voltage. The PWM is transferred across the converter isolation barrier to the primary side, and a primary side circuit receives the PWM signal and outputs a control signal. A controller determines the value of the secondary side output voltage from the control signal and uses the value to control primary side power switching devices of the isolated power converter to regulate the secondary side output voltage at a selected value.
