Comment on Shanghai scientists create computer chip in fiber thinner than a human hair, yet can withstand crushing force of 15.6 tons — fiber packs 100,000 transistors per centimeter

  Depends on the chip design, but modern chips will have (single digit) billions of transistors per square cm.

  The smallest transistors currently in production are the intel 18A which have a gate length of 18 angstroms or 1.8nanometers.

  However this is more of a naming convention than actual size as transistors have moved off planar design for a while now as FINFETS and GAA transistors became the norm.

  The smallest planar transistors are around 22nm which would give you around 450,000 stacked end to end in one cm.

  I however don’t think that’s the core breakthrough here. It’s more about it’s durability seemingly.

  transistors would be bit level (as in several for a single logic gate)
