IBM unveils sub-1 nanometre chip design, packing 100 billion transistors on a fingernail-sized surface

IBM has unveiled a new chip design which it says could enable manufacturers to cram 100 billion transistors on a silicon chip the size of a fingernail.

The current industry-standard size for chips, measured in a the unit of nanometres - a billionth of a metre and the size of a few atoms - is around two nanometres

IBM says it has created the world's first known chip tech below 1 nanometre - but it will be some time before it's ready for production.
