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.
The program is all about devising a physical library of component chips, or chiplets
, that we can assemble in a modular fashion.
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.
The missile gathers information and returns data packets in 30 to 50 kb chiplets
that are 'high-confident' viewable 3D images.
Conceivably an entire conventional circuit board with a variety of different but full-sized chips could be shrunk down onto a much smaller interposer hosting a huddle of yet far smaller chiplets
The "inks" are nanomaterials, molecular semiconductors, inorganic composites, and even tiny silicon chiplets
that form circuits, sensors, light emitters, batteries, and more, integrated directly into products of all shapes, sizes and textures.
By assembling and integrating dozens of chiplets
, mosaic style, on a so-called interposer, which is like a printed circuit board writ small, all of those microsystems functions could be performed in a much closer huddle and can perform more efficiently than if they were distributed in the usual way among a suite of chips attached to a conventional PCB.
