CNFETs are more energy-efficient than silicon field-effect transistors and could be used to build new types of three-dimensional microprocessors.

They found that dry cycling, a method of intermittently drying out the submerged wafer, could dramatically reduce the incubation time — from 48 hours to 150 seconds.

After analyzing the deposition technique used to make the CNFETs, Max Shulaker, an MIT assistant professor of electrical engineering and computer science, and his colleagues made some changes to speed up the fabrication process by more than 1,100 times compared to the conventional method, while also reducing the cost of production. The technique deposited carbon nanotubes edge to edge on the wafers, with 14,400 by 14,400 arrays CFNETs distributed across multiple wafers.

A 3D computer chip with combined logic and memory functions is projected to "beat the performance of a state-of-the-art 2D chip made from silicon by orders of magnitude.
