The breakthrough comes in the form of a new gate design. Instead of making the gate a flat conductor, it was created as a fork. The new design gives better control of the current flowing through the gate, allowing it to be created much smaller; only 18 nanometers long in this case. Hu hopes to cut the size down by another 50% with time.
Refreshingly, there are no plans to patent the discovery; Hu wants the design to be available for everyone's use. With developments like this, it sounds like Moore's Law is going to stick around a while longer.
