On December 6, the family of Professor Zhang Shousheng, a Chinese physicist, issued a statement that Zhang Shousheng died unexpectedly on December 1 after a tough fight against depression.

Almost everyone was shocked, so the conspiracy theory once again became very popular.
Some people listed a series of paradoxical time nodes, it seems that Zhang Shoushengs death is inextricably linked with the chip industry. Even the fire at ASML suppliers in the Netherlands on December 3 has become a part of conspiracy theory.
Some media pointed out in refuting rumors that Zhang Shoushengs research is not directly related to chips.
It can be said that there is no direct relationship, but it does.

Zhang Shoushengs two main contributions are to discover the quantum spin Hall effect and to propose the theory of topological insulators.
These two are related to the information technology industry.
Zhang Shousheng once made an analogy: the movement of electronics in the chip is like a sports car driving in the market. They run in disorder, bump into each other, and their routes are tortuous, so they collide constantly, consume energy and generate heat.
Thats why notebooks work long hours and you can feel them burning.
However, under extremely low temperature and strong magnetic field conditions, electrons can maintain an orderly state of motion. So, under normal conditions, can electronics run in a one-way lane as a car on a highway?
Zhang Shoucheng proposed a theoretical prediction of quantum spin Hall effect. In 2007, a laboratory at the University of Wiltsburg in Germany confirmed the quantum spin Hall effect and successfully experimented on HgTe semiconductor materials.
When electrons no longer collide horizontally, energy loss can be greatly reduced. This provides a possibility for the manufacture of new spintronic computing devices with low power consumption.
Ten years ago, in an interview with Sci-tech Daily, Zhang Shousheng said that he hoped to achieve this effect in conventional semiconductor silicon materials, which could be directly applied to the chip industry in the next five to ten years. It solves the problem of heat dissipation, reduces the energy consumption of transistors, and prolongs the life of Moores law.
However, from todays point of view, Moores law is not going to the end so fast, and his discoveries are not applied to industry so quickly.
Lets look at the topological insulators.
Junior high school physics tells us that materials are divided into conductors and insulators according to the different conductive properties. Topological insulators can achieve internal insulation and surface conduction because of electronic movement. Zhang Shousheng believes that this will become a new material to replace semiconductors.
When our technology is implemented, your cell phone needs to be charged only once a week or a month. Zhang Shousheng said.
In November this year, Wang Bing and Zhao Aidi, professors of Hefei National Research Center for Microscale Material Sciences, University of Science and Technology of China, cooperated with Xu Yong, Duan Wenhui and Zhang Shousheng, assistant professors of Tsinghua University, successfully prepared a single-layer caseine with a flat honeycomb structure, which was confirmed by first-principles calculations. There are topological band inversion and topological boundary states.
It has been reported that stanylene is an ideal two-dimensional topological insulator with large energy gap. It is expected to achieve room temperature quantum spin Hall effect, which is of great significance in the application of topological electronic devices.
However, Zhang Shousheng himself said that stanylene is mainly in the laboratory stage, and there is still a long way to go from the application and production. He also said in 2017 that he hoped that topological insulators would be industrialized in the next five to 10 years.
Therefore, Professor Zhang Shoushengs research has nothing to do with chips. He studies future chip materials, not specific chip technologies. In fact, Zhang Shoushengs basic research, if it can move from theory to application and from laboratory to industrialization, may indeed lead the next revolution of information technology.
But objectively speaking, it really needs time. Some experts in the field of chips told Sci-tech Daily that it took a long time.
As for the fire of ASML, the focus of netizensattention is somewhat deviated.
On the evening of December 3, a fire broke out in Prodrive, the component supplier of Dutch lithography giant ASML, which ASML predicted could affect its shipment plans in early 2019.
Prodrive factory fire
ASML is the core lithography supplier for many large computer chip manufacturers around the world. Its main customers include Intel, Samsung and TSMC. The accuracy of lithographic machine determines the upper limit of chip, while ASML monopolizes the top lithographic machine. But note that this is not ASMLs own fire, nor is there a problem of destroying orders from Chinese customers. Its not just Chinese companies that are affected, but ASML itself is probably the saddest tear. Some things do happen, and there is a sequence at the time node; but it does not necessarily have a causal relationship, which is the common sense of scientific thinking. Linking independent events together creates a meaningful atmosphere that attracts attention but does not necessarily respect the truth.
