The first truly 3D processor.
Scientists from the University of Rochester, in New York, were able to make a three-dimensional processor. Unlike other developments, this 1.4-GHz prototype can be called a truly three-dimensional, since its components are built in a three-dimensional matrix, and all layers are integrated with each other.
Electrical circuits in current chips are located in a two-dimensional plane. And the creation of a three-dimensional processor involves the placement of chains in space. According to scientists, 3D-processors will be more compact and more productive (and several times) of their two-dimensional grandparents.
Attempts to make a 3D chip have already been made. To do this, the basis was taken several conventional chips, which are connected by conductors. The Rochester team went further and created an almost full-fledged three-dimensional processor, in which all layers, due to the complete synchronization of the power supply operation, work as a single system. This was achieved by drilling in a “cube” (namely, that is the name of its processor at the University of Rochester, saying that the word “chip” no longer suits) millions of holes for electrical switching.

Ebi Friedman, a professor at the Department of Electrical and Computer Engineering at the University of Rochester, noted that previously processors "grew" only in the horizontal plane, but due to technology limitations, this could not continue for a long time. Now, adds Friedman, "we will begin to build them vertically, and this will never end."
