IBM says it has built the first sub-1nm chip technology

IBM unveils world's first 0.7nm chip technology with 100 billion transistors

IBM announced the first 0.7nm chip (100 billion transistors) offering 50% performance boost or 70% energy efficiency versus 2nm, with 2031 production target. For AI infrastructure, the energy efficiency breakthrough cuts LLM running costs dramatically; High-NA EUV equipment vendors (ASML) will see exponential demand growth.
