That's a possibility, and that's what the manufacturers are driving for, but it's not guaranteed. All the way back in 2015, we were already seeing projections that cost per transistor would flatline or even increase as process nodes continue to shrink (http://www.monolithic3d.com/blog/intel-the-litmus-test for example).

I have no idea where exactly the state of the art stands (certainly Intel was/is having trouble getting their 10nm to squeeze out any type of economically viable product).
