Microbeam analysis. Scanning electron microscopy. Method for evaluating critical dimensions by CDSEMWhat is ISO 21466 CDSEM about ? ISO 21466 specifies the structure model with related parameters, file format, and fitting procedure for characterizing critical dimension (CD) values for wafer and photomask by imaging with a critical dimension scanning electron microscope (CD SEM) by the model based library (MBL) method. The method is applicable to linewidth determination for specimens, such as gate on wafer, photomask, single isolated or dense line
