  • Patent number: 11961706
    Abstract: The present disclosure relates to an ion beam etching (IBE) system including a plasma chamber configured to provide plasma, a screen grid, an extraction grid, an accelerator grid, and a decelerator grid. The screen grid receives a screen grid voltage to extract ions from the plasma within the plasma chamber to form an ion beam through a hole. The extraction grid receives an extraction grid voltage, where a voltage difference between the screen grid voltage and the extraction grid voltage determines an ion current density of the ion beam. The accelerator grid receives an accelerator grid voltage. A voltage difference between the extraction grid voltage and the accelerator grid voltage determines an ion beam energy for the ion beam. The IBE system can further includes a deflector system having a first deflector plate and a second deflector plate around a hole to control the direction of the ion beam.

  • Publication number: 20210056451
    Abstract: This disclosure provides a solution for processing outliers in a time series. In the method, a time series model is obtained based on a first set of observed values. Outliers are identified from the first set of observed values based on the differences between the first set of observed values and a first set of predicted values. The first set of predicted values is obtained from the first set of observed values by using the time series model. A model evaluation measure representing differences between a second set of observed values and a second set of predicted values is calculated. The second set of predicted values is obtained from the second set of observed values by using the time series model. And replacement values for the outliers are determined in response to the model evaluation measure not meeting a predefined criterion.
