Latest Patents

Chengming Cao holds a patent titled "Method for calibrating parameter error of electron probe microanalysis instrument." This patent discloses a method for calibrating parameter errors in electron probe microanalysis instruments. The method involves preparing a one-dimensional grating standard template using atom lithography technology. A theoretical grating period D is calculated, and the template is placed on the instrument's stage. The instrument scans the template, performs image acquisition, and measures the grid distance to obtain a measurement value L. A calibration factor K is then calculated based on D and L, which shortens the traceability chain for instrument calibration and reduces error accumulation in the measurement process.
