Chapter 581 Problems Caused by Quantum Effects

Although Suiren Company is a life-saving talisman handed over by him, Gu Qing wants it to become a strong anchor company in the Daxia stock and financial market.

Although Big A investors often criticize their own Big A magic banker for rubbish, all financial markets in the world have bankers, and it is not empty talk that there will be no bankers without stocks.

The U.S. stock market has both bookmakers and hot money, and because the U.S. stock market is relatively mature, the majority of people participating in the stock market are institutions, with retail investors accounting for only 20%. Musk, who is currently at the height of his power, has also been beaten by institutional market makers.

The biggest bookmaker is the state, followed by institutions such as the Federal Reserve, then major financial groups, and then various asset management institutions, such as insurance companies, major investment banks, funds, and big-name individuals.

Therefore, people who lose money in Big A will most likely lose money in U.S. stocks.

But compared to the U.S. stock market, Big A is indeed a little bit more powerful, so there is a capable company to support it. This is something the upper management likes to see and is willing to promote.

After discussing with Gu Qing, Dong Qi also chose to take a car back to Suiren Company. By the way, he also brought an extra security team. After all, he felt that he was still very young and could not place his hopes on the kindness of the enemy.

After Dong Qi left, Gu Qing began to process the documents that had been screened by the President's Office and Xuanwu.

Zhang Tianhao and Li You almost walked into Office Building No. 1 together, and would greet their two colleagues affectionately when they met on the way.

At Jiuzhou Technology, although there is no clear distinction between management and employees, the R&D department has always stood at the top of the honor scale.

Not only because of the generous bonuses and project dividends issued every year, but the most important thing is the example set by the executives in the R&D department led by Gu Qing. Almost all old employees know that Jiuzhou Technology can be so prosperous today. More than eighty honors are due to the R&D department.

Without the R&D department coming up with one black technology product after another, what can the factory produce? What can employees do?

Therefore, the popularity of Li You, Zhang Tianhao and others in the company is not low.

After receiving permission, the two walked into the office, and Gu Qing was standing by the floor-to-ceiling window, holding a teacup in his hand and looking at the semiconductor experimental department in the distance.

Looking back at his two generals, Gu Qing sighed softly, "Unknowingly, the company has invested nearly 100 billion in R&D funds in the semiconductor R&D department and its affiliated semiconductor factories.

A R&D team of tens of thousands of people has simply tapped out all the outstanding semiconductor technical talents from domestic universities and private sectors. I really didn’t expect that you can study hard to keep up with this leap. "

The slight teasing between the elders and the younger ones did not make Zhang Tianhao feel out of place, and even Li You, who was already married, did not find it inappropriate either.

In recent years, Gu Qing has treated these R&D personnel like university professors teaching junior high school students in teaching and research. There are even some enthusiastic middle-aged people who came to Kyushu Technology to develop the world's top technology. But after just learning the basic knowledge, there are no such arrogant thoughts as before, and many people will worship and admire Gu Qing.

The self-contained algorithm, language, and system architecture allow many talented people to see clearly the difference between ordinary geniuses and gods.

Li You sighed at the side, "Yes, despite your guidance, teacher, we have spent countless days and nights on equipment modification and production line research and development. If it weren't for the fact that the company's investment in semiconductors has snowballed more and more resources over the years, I'm afraid. We won’t be able to reach the 5nm threshold until Xiayin Star Calendar 1025.”

Zhang Tianhao also nodded in agreement and said to Gu Qing: "It's just that now that this threshold has been crossed, we have found that quantum effects have become more and more obvious in the most advanced manufacturing processes. No matter how we change the design ideas, electronic devices and signal behavior Abnormalities cannot be controlled stably.”

Gu Qing glanced at Zhang Tianhao. He was so impressed by this kid. He was obviously just learning mechanics, but he didn't know whether it was because he had been opened up to the second line of Ren and Du or if he had gone in the wrong direction before. Ever since Zhang Tianhao came into contact with the semiconductor research and development project, he has been in trouble. After all, his knowledge of semiconductors now exceeds that of ordinary university professors.

He said to Zhang Tianhao: "You started in machinery. For most chip industries, quantum effects are actually a common topic, and foundries and equipment manufacturing companies like TSMC and Xiaxin are directly affected by quantum effects. Companies spend huge amounts of resources every year just to use new processes, equipment and even new architectures to minimize the quantum impact.

Although the 3nm process advocated by Korean Star and TSMC is a process that does not live up to its name, their foundry accuracy is indeed approaching 5nm step by step. Problems such as quantum tunneling will eventually lead them to follow Intel's old path of using the same process. Crazy use of '+' to differentiate from the previous generation.

For example, as a result of gate dielectric scaling and an increase in the electric field within the device, the carriers in the inversion layer are no longer located at the silicon dioxide-silicon interface, but somewhere below, thereby increasing the effective dielectric layer thickness.

This effect has existed in CMOS technology for some time, and as transistors become smaller and smaller, more quantum effects will definitely occur in the future. "

When Li You heard this, he nodded in agreement: "For example, some things have body inversion. When we start talking about very thin FinFET devices, or even nanowires, instead of surface inversion, the device will suddenly be completely exhausted.

When we turn it on, the center of the wire will reverse before the edge. These are very interesting results, but the basic principles behind them are the same. They are just like the topics that the teacher assigns to us every month. They seem very simple, but in practice, accidents always happen. . "

Gu Qing was noncommittal. He smiled and asked, "Why, you can't do this month's questions?"

Although he was smiling, as an adult with a family, Li You subconsciously felt nervous when he saw Gu Qing's smile.

"Although it is difficult, students will solve it seriously."

Gu Qing waved his hand gently and said: "Silicon-based chips can reach 5 nanometers, and carbon-based chips will naturally not be too difficult. As long as you open your mind and don't limit yourself to past experience, you will definitely be able to solve it.

You also need to have a good communication atmosphere within yourself. After all, I am not an omniscient and omnipotent God, and many problems are also bothering me. "

Zhang Tianhao wanted to ask Gu Qing about his homework, but after hearing what Gu Qing said, he controlled himself.

Gu Qing continued: "Today I asked you to convene the management and technical backbones of the R&D department to announce a very important matter. Are they all here?"

Li You nodded: "Except for the ones sent abroad who didn't come, the rest of the staff have already arrived at the underground base."
