IBM has unveiled what it calls the world’s first sub-1 nanometre (nm) chip technology, a research breakthrough that the company says could extend advances in semiconductor performance as the industry approaches the physical limits of transistor scaling. The prototype, built on a 0.7nm (7 angstrom) process, uses a new three-dimensional Nanostack architecture that vertically stacks transistors instead of relying only on shrinking them. IBM said the technology is designed to support increasingly demanding artificial intelligence (AI), cloud computing and high-performance computing workloads.The announcement comes as chipmakers look for new ways to sustain the pace of innovation described by Moore’s Law, the principle proposed by Intel co-founder Gordon Moore that the number of transistors on a chip would roughly double every two years. Who will win the AI chipset technology ?
