The Old Summer Palace has been launched, Jiangyan Ali, Huawei and ZTE four companies have joined forces, and after the promotion of the whole network, it soon set off a round of trend in China, and many industrial enterprises have settled on the platform.

There are three platforms in the Old Summer Palace, the handmade platform mentioned earlier, and then two platforms for light and heavy industry. In the past, the handicraft industry was divided into light industry, and the three platforms of the Old Summer Palace were a new method of division.

The reason for this division is to make everyone pay attention to the handicraft industry.

Among the many settled enterprises, the four companies attach the most importance to high-tech enterprises in the light industry. However, the number of high-tech enterprises is relatively small, and the number of people settled on the platform is even less, so it is difficult to find a suitable one.

When Hang Yu has time, he logs in to the Old Summer Palace and looks for suitable companies for investment on it.

"Micro Semiconductor. Hang Yu saw a somewhat familiar name, and then looked at the name of the chairman and CEO, and he gradually remembered.

This company became a bit famous in later generations and was founded by a person named Yin Zhiyao.

Yin Zhiyao was admitted to the Department of Chemical Physics of the University of Science and Technology of China in 1962, then worked in the Lanzhou Oil Refinery, and transferred to the Lanzhou Institute of Physical Chemistry of the Chinese Academy of Sciences in 1973, and later studied for a master's degree in the Department of Chemistry of Peking University.

In 1980, with the help of some relatives in the United States, he came to the University of California, Los Angeles to study for a doctorate, and received a doctorate in physical chemistry in three and a half years, and Yin Zhiyao has been working in Silicon Valley until 03.

He started his career as a plasma etching in Intel's central technology development department. In 1986, he moved to the LAM Institute, first as a senior engineer and later as a technical development manager.

Yin Zhiyao is responsible for the development of rainbow plasma etching equipment, and LAM has become one of the leaders in this field with some very good products.

In 1991, Yin Zhiyao came to the world's largest 10-billion-dollar semiconductor equipment company, Applied Materials, the leader of semiconductor equipment manufacturers, and served as the vice president of the head office.

Yin Zhiyao is responsible for research and development in the same field, has obtained 86 patents in the United States and abroad, and was once known as "one of the most accomplished Chinese in Silicon Valley".

In 2004, 60-year-old Yin Zhiyao resolutely gave up his million-dollar annual salary in the United States, breaking through the layers of scrutiny of the U.S. government, and all process formulas and design drawings were confiscated by the United States.

It is similar to Qian Lao's return to China, but it is not so difficult, and after returning to China, he founded China Micro Semiconductor.

Yin Zhiyao, who is 60 years old, gave up the superior material treatment of the United States and returned to China to start a business, Yin Zhiyao said: "We have done a lot of things to make wedding dresses for foreigners, so we should make some contributions to our motherland and people, so we are determined to come back." ”

Yin Zhiyao came back with 30 senior engineers with 20-30 years of experience in semiconductor equipment R&D and manufacturing in international giants such as Applied Materials and Colin.

At the time of their return, all the technical experts promised not to bring back the technology of the American company, including the design drawings and technological processes, and the American side also conducted a thorough inventory of the more than 6 million documents and all personal computers held by the returnees.

After returning to China, Yin Zhiyao's team started from scratch, re-developed and applied for patents, and finally in 2008, the etching machine of China Micro Semiconductor began to enter the international market.

In this case, foreign companies could not accept that the Chinese could make a high-performance etching machine within 3 years, and Applied Materials and Colin successively filed patent lawsuits against China Micro Semiconductor.

After AMEC came up with patent evidence for key technologies, two extended lawsuits ended in the victory of AMEC.

"This company is good, not only has strong scientific research strength, but also has certain results, which is worth our investment. Hang Yu sent the information of China Micro Semiconductor to Yue Qin and the four of them, and asked them to also consult.

Chip memory belongs to the semiconductor industry, and China's semiconductor technology is seriously backward.

If you want to do chip internal testing, you have to make semiconductor manufacturing equipment first, and AMEC does this. Yin Zhiyao is a group of high-end talents, and it is difficult to recruit them for money.

"The team is very strong, but they just raised their fourth round of financing in March, and we are investing now, so the other party should not say it first, the key is that it is not worth it. Yue Qin looked at the information and quickly asked questions.

"Why isn't it worth it?" asked Hang Yu.

"There are already a number of companies raising funds, and we entered so late that we must have very few shares. And the etching machine they make, we don't seem to have this demand, and the market is not particularly large. Yue Qin said.

Etching machine is an important equipment for chip production and manufacturing, and many people will confuse lithography machine with etching machine.

In fact, lithography and etching machines are two kinds of equipment, and the working principle of lithography machine is to use a laser to temporarily copy the circuit structure on the mask onto the silicon wafer. The etching machine is a device that engraves microscopic grooves or contact holes on silicon wafers according to the circuit structure carved out by the lithography machine.

The plasma etching machine has very high requirements for machining accuracy, which is 1/10000 to 1/10,000 of the diameter of a human hair. In the case of a 16nm CPU, the processing scale of plasma etching is one-thousandth that of an ordinary person's hair, and the processing accuracy and repeatability should reach one-fifty-thousandth.

Although the etching machine is technically difficult and belongs to particularly advanced equipment, and few manufacturers can manufacture it, the market is not very large. The main reason is that there are not many people who need etching machines, and the companies that can make chips and memory all over the world can count them on their fingers.

"Sooner or later, we will also enter the field of chips and memory, and if we don't need it now, we will have it in the future. The purpose of my investment in AMEC is not to make money, but to pave the way for the future research and development of mobile phone chips and memory. Hang Yu said.

"I see, then you don't care about how many shares you have, just a little bit of shares. Yue Qin said.

"Let's get in touch with them first, get to know them completely, and then I'll leave this task to you. Hang Yu said.

"Okay, I'll go tomorrow. Yue Qin replied.

"There are also San'an Optoelectronics, SMIC, Changdian Technology, these three companies you can also inspect. Hang Yu said.

"I remembered. Yue Qin nodded.

San'an Optoelectronics is mainly engaged in LED, and SMIC is mainly engaged in integrated circuit chip foundry.

SMIC's technology is not high, it is still at the forty or fifty nanometer level, which is too far from the 10-nanometer process in Japan and South Korea. However, it is already very good in China, Hang Yu wants to exchange technology, of course, not by himself, but by sending people.

"By the way, take a look at the progress of the new factory in Suzhou. Hang Yu said again.

"Okay. Yue Qin replied.

The equipment and technology of the new factory in Suzhou are much higher than those of the old factory, and the investment is much larger, and it is a new generation of screen manufacturing factory. In the plan, the new generation of screens will enter the high-end field, although it has not yet reached the level of craftsmanship in Japan and South Korea, but it is almost the same.

"If you can't catch up with the launch of the new mobile phone, you can only find Japanese and Korean companies to OEM. Hang Yu said.
