Yes, single-atom manipulation has already been demonstrated:

Can you make transistors using that technique? Can you smaller?

  • You could make maybe ten transistors or so, but no more. That technique is quite literally pushing atoms one by one with a sharp needle. Not scalable, though maybe useful for some quantum computing platforms’ fabrication since we’re at early stages.

    And you could write nice sci-fi about subatomic transistors, but forget making them in this reality.
