World's first 1 nanometre Risc V chip


China’s chip industry has reached a major milestone after scientists developed the world’s most complex semiconductor microprocessor.

As silicon-based integrated circuits approach the physical limits of miniaturisation, researchers worldwide have turned to 2D materials, such as molybdenum disulphide and tungsten diselenide, to push the boundaries of chip performance. Typically only one atom thick, these materials offer remarkable physical properties, enabling further scaling and improved functionality in next-generation circuits. Although wafer-scale growth of 2D materials has been achieved over the past decade, until now the most complex 2D semiconductor digital circuit – developed by the Vienna University of Technology in 2017 – contained just 115 transistors.
