Core Viewpoint - A new microchip named RV32-WUJI, made from molybdenum disulfide, features nearly 6,000 transistors, marking a significant advancement in two-dimensional semiconductor technology and a potential alternative for the post-silicon era [1][2]. Group 1: Microchip Development - The RV32-WUJI microchip contains 5,931 transistors, significantly surpassing the previous record of 156 transistors in two-dimensional logic circuits [1]. - The chip is built on an insulating sapphire substrate, which isolates the transistors electronically [2]. - Researchers have developed a complete standard cell library with 25 logic units for basic functions like AND and OR [2]. Group 2: Manufacturing and Performance - The manufacturing yield achieved is 99.77%, despite the complexity of two-dimensional semiconductors and wafer-level processes [2]. - The transistor channel length is currently 3 micrometers, with plans to use better lithography tools to further reduce channel size and increase integration density [2]. Group 3: Power Consumption and Future Prospects - At a frequency of 1 kHz, the RV32-WUJI consumes only 0.43 milliwatts of power [3]. - While silicon chips have millions of times more transistors and operate at much higher frequencies, the researchers believe that embracing two-dimensional semiconductors could lead to performance surpassing silicon-based semiconductors faster than expected [3].
