Methods to improve resolution of cross sectioned features created using an ion beam

摘要

Methods for creating a cross section of at least one feature located on a substrate are disclosed. The methods include coating the feature with a layer of contrast enhancing material, recoating the feature with a second material that is different from the contrast enhancing material, and milling the feature. The second material has substantially similar milling characteristics as the feature. The methods may further include creating an image of the feature and saving the image of the feature.
