Graphical Abstract
  • process. In the future, it is planned to carry out a set of works to improve the barrier properties of aluminum oxide. The quality of the barrier largely depends on the roughness of aluminum. It can be critically large during electron beam deposition, which in turn affects the thickness of the barrier and
  • the leakage resistance. We now test various ways to reduce the aluminum roughness. Also, the roughness strongly depends on the deposition rate. The oxidation process affects the barrier properties as well; perhaps with dynamic oxidation [26] (with constant pumping) one can try to achieve better
