RE: 3D transistors promise to deliver 20Ghz to 50 Ghz processor speeds!
It was only a matter of time before they began stacking layers of elements on top of each other and using electron streams to cut the junctions. It seemed the only logical approach. In the early 80's they found that using electron mocroscopes to look at the chip elements was blowing holes in the samples so it seemed the next approach would be to use that beam to do the actual fabrication of the elements.
