Abstract
An electron-beam deposition in SEM has been successfully applied to make a new type of STM microtip of submicron diameter. This microtip has a straight shank and enables us to obtain low-distorted STM images of microfabricated patterns. Analyses of the microtip by TEM, Auger and atom-probe indicate that the microtip is amorphous and mainly consists of carbon, oxygen and hydrogen.
