Sharp Tips Direct Writing on AFM cantilevers

Sharp Tips Direct Writing

The NanoMaker was successfully used for direct writing by e-beam the sharp tips for Atomic Force Microscope. So called "Whisker Type" tips are used to go deeper inside narrow gaps when the standard cantilevers fail to measure the bottom and to control near vertical sidewalls. For more information look at site of AFM manufacturer NT-MDT Co.
