Under a microscope, four slivers of silicon — electronic circuits called chiplets — perform an elaborate, jerky dance as if controlled by a hidden puppet master. Then on command, they all settle with pinpoint accuracy, precisely touching a pattern of circuit wires, each at just the right point of contact.
The technology, on display at Xerox’s Palo Alto Research Center, or PARC, is part of a new system for making electronics, one that takes advantage of a Xerox invention from the 1970s: the laser printer.
