Etching precisely the right depth so that the top surface of the chiplet
and the top surface of the silicon wafer are vertically within a micron or two of each other is difficult.
CEA Leti and STMicroelectronics detailed research on a new 3-D architecture using chiplets
on an active interposer.
" approach seems to be gaining steam, not only to increase yields and cut cost, but also to mix and match different types of logic, memory and I/O--manufactured on different processes--in the same MCM.
But researchers at PARC, in Palo Alto, California, envision doing something different with the wafers: chopping them up into hairs-width "chiplets
," mixing them into an ink, and guiding the tiny pieces electrostatically to just the right spot and orientation on a substrate, from which a roller could pick them up and print them.
"We will be able to make microprocessors using standard printing methods," says PARC CEO Stephen Hoover, "without high-temperature processing or nasty chemicals." The Xerox branch envisions a new age of ultra-low-cost electronic "chiplets
," each no bigger than a grain of sand, the technology that will enable the world of stuff around us humans to have its own autonomous connectivity and intelligence--The Internet of Things.
No, really, take it because I couldn't come close to finishing this layered, coffee-cream and cake-layered monstrosity buried beneath semisweet chocolate chiplets
and a dusting of powdered sugar.
A major aspect of the CHIPS vision is the eventual availability of a library of custom and commercial "chiplets
"--small-scale chips that individually embody a particular function, such as data storage, computation, signal processing, and managing the form and flow of data.
