8 September 2014 Technique for AFM tip characterization
Author Affiliations +
In atomic force microscopy (AFM) metrology, the scanning tip is a major source of uncertainty. Images taken with an AFM show an apparent broadening of feature dimensions due to the finite size of the tip. An AFM image is a combination of the feature shape, the tip geometry and details of the tip-sample interaction. Here we describe the use of a new multi-feature characterizer for CD-AFM tip, and report initial measurement results. The results are compared with those obtained from the current tip characterizer.
