How many nm can Chinese chips currently achieve?

China's chip production can only reach 14 nanometers.

Everyone has witnessed the difficulty of the development of domestic chips. In addition to being affected by the general environment and being constantly sanctioned by the United States, there is no way for core industries to obtain patented technologies. What they can do We can only rely on labor force to do some basic things. Even though we are catching up now, we don’t know how many years it will take to really catch up with the international level. In addition to external reasons that hinder the development of chips, we should also look for the reasons within ourselves.

According to current data, China’s chips can only reach 14 nanometers, but the United States can reach five nanometers in chip manufacturing. This quantitative advantage means that their development is stronger, but Even so, the United States does not want to let China go, and has even been restricting China in the development of some applications. This shows that the gap between Chinese chips and foreign chips is far away.

Introduction to the development of integrated circuits in chips:

The most advanced integrated circuits are the core of microprocessors or multi-core processors and can control everything from computers to mobile phones to digital microwave ovens. Although the cost of designing and developing a complex integrated circuit is very high, when spread over often millions of products, the cost per integrated circuit is minimized. Integrated circuit performance is high because the small size brings short paths, allowing low-power logic circuits to be used at fast switching speeds.

Over the years, integrated circuits have continued to develop into smaller form factors, allowing each chip to package more circuits. This increases the capacity per unit area, which can reduce costs and increase functionality. See Moore's Law, the number of transistors in integrated circuits doubles every 1.5 years. In short, as the form factor shrinks, almost all indicators improve, unit cost and switching power consumption decrease, and speed increases.

However, ICs integrating nanoscale devices also have problems, mainly leakage current. Therefore, the increase in speed and power consumption is very obvious to the end user, and manufacturers are faced with acute challenges to use better geometries. This process and the advancements expected in the coming years are well described in the International Technology Roadmap for Semiconductors.

Just half a century after their development, integrated circuits have become ubiquitous, with computers, cell phones, and other digital appliances becoming an integral part of the fabric of society. That's because modern computing, communication, manufacturing and transportation systems, including the Internet, all depend on the existence of integrated circuits. Many scholars even believe that the digital revolution brought about by integrated circuits is the most important event in human history.
