The Smallest Chip Ever - IBM Two-Nanometer Chip

It is hard to understand how much power a 50B transistor IC can have!

Still remember back in late 80s, my professor said that 40nm and 80MHz were the absolute limit for silicon based semiconductors on a lecture on Friday.

I wish I had his contact info to ask him what he thinks of this :)

IBM’s 2-nanometer (nm) chip technology puts 50 billion transistors, each the size of roughly five atoms, on a space no bigger than your fingernail. The landmark technology—the smallest, most powerful microchip ever developed—could quadruple the life of cell-phone batteries and slash the carbon footprint of data centers, among other things. Now the manufacturing competition is on. Samsung and the Taiwan Semiconductor Manufacturing Co. have announced plans to produce the chip by 2025, and in August, the U.S. and Japan unveiled a plan to build a joint research center focused on 2-nm tech.

China's 7nm chip surprise: Not as worrying as it looks • The Register

Duplicating the TSMC N7 process must have been hard, expensive and high priority. But it leads nowhere. What we see when we pop that chip open is not a scarfy future, but a tiny white elephant bathed in deep ultraviolet.

China is learning to build the world's finest propeller engine, just as its competitors enter the jet age. Admire the effort, but don't cash in your chips just yet.
