IBM says it's built the world's first 2nm semiconductor chips
Coming to a computer near you ... this decade ... maybe Katyanna Quach Thu 6 May 2021 // 23:04 UTC Share Copy IBM Research says it's made the world’s first 2nm chips, squeezing 50 billion transistors onto each of the fingernail-sized dies. Big Blue today claimed this is “a breakthrough in semiconductor design” using nanosheet technology. That involves layering three sheets of material to form a stack containing an NMOS transistor on top of a PMOS transistor, rather than placing them side by side, commonly called a gate-all-around design. It's a step on from today...
