Chinese Scientists Develop Advanced Semiconductor Material for AI Microchips

• Chinese scientists developed a 0.7-nanometer semiconductor, enhancing AI chip speed and energy efficiency.
• New TMD-based chips surpass silicon in power consumption and electron transport, ideal for advanced tech.
• The “grow at interface” technique boosts precision in microchip production, promising powerful AI applications.

Chinese scientists have made a breakthrough in semiconductor technology, introducing a novel ultra-thin material that promises to enhance the speed and energy efficiency of microchips. These advancements aim to revolutionize artificial intelligence applications in modern devices.

A team led by Zhang Guangyu from the Chinese Academy of Sciences and Liu Kaihui from Peking University has developed a semiconductor material only 0.7 nanometers thick. 

This new material, significantly thinner than traditional silicon, could potentially address the physical limitations currently faced by silicon chips as electronic devices continue to shrink in size. Traditional silicon chips, typically between 5 to 10 nanometers thick, struggle to maintain performance at reduced sizes.

The researchers focused on two-dimensional transition-metal dichalcogenides (TMDs) as an alternative to silicon. TMD-based chips not only consume less power but also exhibit superior electron transport properties. These characteristics make them ideal for the next generation of photonic and electronic chips. 

The traditional silicon fabrication process often results in impure crystals due to the layer-by-layer assembly of atoms, leading to uncontrollable atomic arrangements and defects. In contrast, the new method, termed “grow at interface,” positions subsequent atoms between the crystal’s first layer and the substrate, ensuring precise atomic alignment and reducing defects.

According to information from Peking University, the new technique achieves a crystal layer formation rate of 50 layers per minute, with a maximum capability of creating 15,000 layers. This method ensures each atomic layer is perfectly parallel and adheres to international standards for integrated circuit materials, using substances like molybdenum disulfide and niobium disulfide.

Liu Kaihui highlighted that these 2D crystals, when integrated with other materials, significantly enhance chip integration. This improvement could lead to a substantial increase in transistor density, thereby boosting computing power on microchips as small as a fingernail.

The advancement offers promising prospects for the future of AI devices, potentially transforming how these technologies are developed and implemented.

The creation of this new semiconductor material is a big advancement in microchip technology. With more research and improvement, it could result in more efficient and powerful AI applications, creating new industry standards.

The breakthrough by Chinese scientists underscores the ongoing advancements in semiconductor technology and its critical role in the future of electronic devices.
