Moore's Law lives
Intel's newest line of processors, named Ivy Bridge, are three-dimensional and incorporate features as small as 22 nanometers (as opposed to today's chips with features as fine as 32 nanometers).
Existing transistor designs—little changed in decades—could not simply be made smaller, with 22-nanometer features. That would cause them to become leaky, so that a transistor would allow some current to flow even when set to off. Intel got around that by adding an extra dimension to transistors, which for decades have been made as a stack of flat layers of material on top of one another.
