World's First Molecular Transistor Created by Scientists

This is a big step: as the year 2022 looms, the transition to 11nm will too.  Current fabrication techniques are nearing the end as of now due to R&D costs and the effects of quantum tunnelling at such small dimensions.  To achieve 11nm processes, other non-CMOS technologies might have to be used, including nanotechnology.  Nanotech got a big boost this year as a Benzene molecule was used as a transitor:
The researchers were able to manipulate the molecule's different energy states depending on the voltage they applied to it through the contacts. By manipulating the energy states, they were able to control the current passing through the molecule.

"It's like rolling a ball up and over a hill, where the ball represents electrical current and the height of the hill represents the molecule's different energy states," Reed said. "We were able to adjust the height of the hill, allowing current to get through when it was low, and stopping the current when it was high." In this way, the team was able to use the molecule in much the same way as regular transistors are used.
