High-resolution microscopy advance could shrink CPUs beyond current limits (feeds.arstechnica)
Modern life would be very, very different if it weren't for photolithography,
a very simple step in the processes for making an integrated circuit.
Essentially, you use a slide projector to project an image of the circuit
pattern on a wafer. Exposing the wafer to a light pattern modifies a chemical
layer on top of the wafer, creating a mask. The mask allows selected parts of
the wafer to be processed to create the circuit.
Despite its relative simplicity, photolithography is the limiting step that
governs the rate at which power consumption drops, speed goes up, and the
number of transistors increases. As you might imagine, a lot of people have
spent a lot of time trying to improve or replace photolithography with a
history of success.
