Abstract :
In this work, a conductive atomic force microscope (C-AFM) built in a vacuum environment has been used to characterize the electrical properties of high k samples. In particular, the effect of the annealing on the electrical characteristics of ALD HfO2 samples has been investigated by this technique.
