Intel microprocessors add a third dimension

The microprocessors that power today’s computers are running out of space. For decades engineers have found ways to shrink the circuitry that’s etched onto each chip’s surface, but that trend will soon collide with hard laws of physics. Intel engineers may have found a way to continue the relentless march toward ever-faster computers: 3D circuitry containing tiny fins of silicon that rise above the chip’s surface.
