On each microprocessor there are billions of transistors and nm (nanometer) – the unit of measurement of transistor size. The smaller the size, the more transistors the processor can hold, making it faster and more efficient. TSMC’s most advanced chip today uses a 5 nm process with about 173 million transistors per square millimeter. Silicon chip wafers in TSMC’s production line. Photo: TSMC. This breakthrough was discovered by the MIT team, with components optimized by TSMC and improved by NTU. The core component uses semi-metallic bismuth as the electrode of a two-dimensional material to replace silicon, allowing for reduced resistance and increased amperage. Energy efficiency will thus rise to unprecedented heights in the semiconductor industry. Chipmakers have been trying to stuff more and more transistors into increasingly smaller chips, but are nearing the limits of silicon-based technology. That prompted scientists to look for two-dimensional materials to replace silicon to produce chips on the 1 nm process or smaller. More transistors on a chip gives manufacturers more options to deliver core innovations to improve performance for leading tasks like AI and cloud computing, and pave the way for better security. Encryption and encryption are performed by hardware. The need to increase performance and save energy in each processor has never cooled down, especially in the era of the cloud, AI, and IoT. Most of today’s chip-integrated devices use 10 nm or 7 nm process technology. The two largest chip manufacturers in the world, TSMC and Samsung, are launching chips with the 5 nm process, while Intel is still at the 7 nm stage. TSMC also only plans to start moving to the 4mm process later this year before mass production in 2022.

While today’s most advanced technologies can produce chips as small as 3 nm, the new technology will “break the limits of Moore’s law”, said Chih-I Wu, Professor from NTU and co-author of the paper. research said.

One of the obstacles when it comes to improving the chip manufacturing process lies in the structure and choosing the right materials. According to the Tom’s Hardware , shrinking the chip size but denser transistors can increase the resistance at the electrodes, affecting the performance. Research shows that using bismuth as an electrode significantly reduces resistance, increasing transistor amperage. Currently, TSMC’s technology uses tungsten as the electrode, and Intel’s cobalt. TSMC’s sub-1nm chip manufacturing technology is still being tested before mass production in the next few years. Alternatively, further studies may consider using a different electrode material instead of bismuth. Discovered in 1965 by Intel co-founder Gordon Moore, Moore’s law has become the rule for the advancement of semiconductor technology. According to this law, the number of transistors on a chip will double every 2 years, while the power consumption is halved. Over the years, chip companies around the world have continuously invested in semiconductors, a technology field that is considered a key future. In early May, the US company IBM introduced the world’s first 2 nm chip manufacturing technology. This process can quadruple smartphone battery life, cut data center carbon emissions, speed up laptops, and support high-performance artificial intelligence (AI). China is also looking to catch up with the US in semiconductors, amid technological advances that could cause Moore’s law to break. According to the SCMP , the Chinese government has proposed a five-year plan, referring to the potential semiconductor technology “post” Moore’s law. What if humans had chips in their brains Elon Musk creates an AI-powered device that interacts with the human brain. But is that really a good idea?
