China firm develops one-nanometer thick RISC-V chip with 2D materials
Developed by China's RiVAI Technologies, the Lingyu CPU supports high-performance computing like large open-source language models DeepSeek.
Scientists across the world are turning to 2D materials like molybdenum disulphide and tungsten diselenide for microprocessors at a time when silicon-based integrated circuits approach the physical limits of miniaturization. “Our combined manufacturing and design methodology has overcome the significant challenges associated with wafer-scale integration of 2D circuits and enabled a pioneering prototype of an MoS2 microprocessor that exemplifies the potential of 2D integrated-circuit technology beyond silicon,” said researchers in the study. The push for RISC-V adoption comes in response to ongoing trade tensions and sanctions that have limited China’s access to advanced foreign-made chips.
