Well in terms of probably the most important piece of technology today, the microprocessor (specifically the transistor), yes.
We are approaching the semiconductor fabrication wall. Every so often, the gate length of a MOSFET used inside every chip in every electronic device is reduced. Right now we are at 22 nanometers. Hardware enthusiast will recognize this number. As the gate length gets smaller, the more transistors we can pack on a single die making the chip not only faster but use less power. Oh and cheaper. Moore's Law. The graph below shows the continuous progress the fab industry has made over the last 40 years.

At about 10nm, things get scary. If they work out the scary things, there is a definite wall which is the gate must be of some length, but you can't shrink the SiO2 molecules which compose the gate. Another way to put it: The distance between 2 points of some material could be counted in terms of the number of molecules which compose the material. You can reduce that distance only as far as 1 molecule while still having a measurable length. So once we hit that wall, something drastic needs to happen.
