João Paulo Cosas Fernandes

Hello !

Yes, it is possible. I suggest you get more information in the literature, you can start with this review:

Chapter Focused Ion Beam System—a Multifunctional Tool for Nanotechnology

Best of luck !

Joao

Muhammad Shahbaz Anwar

Yes, it is possible, following article would help you,

Article Multiple-barrier and nanoscale superconducting devices

Jules Lloyd Hammond

As the others have mentioned, it is definitely possible. However, it is unlikely to be the most time-efficient method.

If you can give more details on the structure you are trying to create I am sure the RG community can offer suggestions on how best to achieve this.
