3D transistor, a real thing now

As the designated enforcer of Moore's Law, Intel has consistently found a way to keep its two-year process shrink cadence on schedule. This time it's with three-dimensional semiconductors, by "re-inventing" the transistor with its new 3D Tri-Gate technology. Intel will begin churning out the Tri-Gate silicon in its upcoming "Ivy Bridge" processors, the 22nm shrink of the current generation 32nm Sandy Bridge processors. Intel maintains the 3D transistor technology will only add 2 to 3 percent to the cost of manufacturing the wafers, so system costs should take only a minor hit.
