In the context of increasingly fierce technological competition between China and the United States, chips, as the core of information technology, have become the focus of competition between both sides.In recent years, the United States has continuously exerted pressure on China's chip industry, attempting to block China's entry into the high-end chip field.

However, China has not retreated in the face of challenges, but has accelerated the pace of chip localization and achieved some exciting and important results.But while China is still cheering for the small achievements of domestically produced chips, the United States has already achieved revolutionary breakthroughs in chip technology, bringing greater challenges to China.

Recently, an interdisciplinary research team from the Massachusetts Institute of Technology (MIT) in the United States published a world-renowned paper in April 2023. They announced thatSuccessfully developed an atomic level thin transistor based on molybdenum disulfide (MoS2).This innovative transistor technology has attracted the attention of the global technology community. The new type of transistor canUtilizing an atom to store information and utilizing atomic scale fluctuations and quantum mechanical properties, allowing electrons to have a completely new way of motion in chips.This breakthrough development is expected to break through the limitations of traditional Moore's Law and achieve higher integration and performance.

Moore's Law is an empirical law proposed by Gordon Moore, one of the founders of Intel, which describes the exponential growth growth trend of the number of transistors that can be accommodated on integrated circuits over time. However, as transistor sizes continue to shrink, Moore's Law faces physical and economic challenges.The traditional silicon based transistor adopts a three-dimensional structure, and the horizontal arrangement method not only improves chip performance, but also brings problems such as arrangement density, tunneling effect, heating, and power consumption.

Unlike traditional transistors, MIT's research team used molybdenum disulfide, an excellent two-dimensional material, as a semiconductor material. Molybdenum disulfide is a transition metal disulfide material with excellent photoelectric properties and mechanical strength. It has a broad application prospect in the manufacturing of flexible electronic devices, wearable technology, intelligent textiles and other fields.This ultra-thin transistor is only three atoms thick each, arranged vertically, providing new possibilities for more dense, powerful, and flexible chip designs.

The research team has also successfully developed another remarkable technology:A low-temperature process for directly growing two-dimensional material layers on silicon CMOS wafers.The innovation of this process lies in the absence of a transfer process, which not only protects silicon transistors and circuits from high-temperature damage, but also greatly shortens the growth time and ensures the smoothness, uniformity, and high quality of the material layer. This breakthrough technology not only has strong commercial potential, but also exhibits broad application prospects.

This technology was developed under the leadership of a Chinese scientist named Zhu Jiadi, and his team achieved great success in this research. As a doctoral student in the Department of Electrical Engineering and Computer Science at MIT, he was awarded the Outstanding Self funded International Student Scholarship by the National Natural Science Foundation of China (NSFC) in 2019. Zhu Jiadi explained that,Their research is like building a multi-story building. Traditionally, a single floor cannot accommodate a large number of people. However, by using heterogeneous integration technology, they used silicon as the first layer and directly integrated multiple layers of two-dimensional materials onto it.

This revolutionary breakthrough will further promote the development of chip technology and bring new opportunities for global technological innovation. However, for China, facing the leading advantage of the United States,Relying solely on technological breakthroughs is not enough to ensure the comprehensive rise of the chip industry. China needs to strengthen its innovation capabilities, increase research and development investment, and cultivate a high-quality talent team in order to promote the development of the chip industry to a higher level.

At the same time, the development of these technologies has also attracted attention and discussion from the scientific community and media. Some people believe that this is a revolutionary breakthrough in the chip field by the United States, posing a huge threat to the development of Chinese chips. Some people believe that this reflectsThe "shame" of China's talent loss problem,Encourage us to reflect on our own problems. At the same time, some people believe that this is an inevitable phenomenon in the technology competition between China and the United States, and we should face the challenges and accelerate independent innovation.

In fact, China has realized the importance of the chip industry and has taken a series of measures to accelerate independent research and production. For example, promoting the autonomy of the chip industry chain,Increase investment in the chip field, support the innovative development of local enterprises, etc

From 2022 to March this year, China's demand for imported chips from countries such as the United States decreased by 129.1 billion. In addition, we are also at the forefront of the world in the field of quantum chips. China has established its first domestic quantum chip production line, non-destructive probe station, laser annealing instrument and other key facilities,And we have developed the first 100% self owned quantum chip industrial software "Benyuan Kunyuan".

However, we still cannot take it lightly. There is still a huge gap between us and advanced countries in semiconductor basic research, equipment manufacturing, and high-end design. At the same time, we also face severe challenges in cultivating and retaining talents in semiconductor physics. In addition, there are still many loopholes in our core patent technology and intellectual property protection.

Huawei founder Ren Zhengfei once said:It's not others who are holding us in the neck, but ourselvesHe emphasized that we should attach importance to basic scientific research, increase investment in education, focus on talent cultivation, and tackle core technologies. Only in this way can we achieve the autonomy and controllability of chips, no longer subject to human constraints.

In today's era of rapid technological development, we are facing unprecedented challenges. Instead of feeling narcissistic about small breakthroughs or panicked after being made by others, one should focus their energy and time on tackling core technologies. A slight negligence may cause us to be five years behind, while a slow step may cause us to be 20 years behind. The huge gap in technological backwardness is often only a year or two. Time is very precious in technological innovation, and it may take even longer to catch up or even fall behind. Therefore, no longer waiting or relying on others, actively invest energy and time to strive for technological breakthroughs.

Recognize the importance of time, no longer self deprecating or panicking. Pay close attention to core technologies, encourage innovation, research and development, cultivate talents, and strengthen cooperation and exchange. Overcome core technical challenges, establish a firm foothold, and maintain a competitive advantage. Actively leading technological progress, rather than passively waiting for others to surpass.
