Rebirth 1999: Opening the Age of Black Technology

Use copper clad laminates (mostly PCB copper clad laminates) to print circuit diagrams on the copper clad laminates with a printing machine, and then use an engraving machine to engrave according to the printed circuit diagrams, and finally solder related electronic components.

Likewise, the same goes for chips.

The role of the lithography machine is similar to that of a printing machine.

It's just that the size of the chip is too small and requires special printing.

The specific method is to cover a layer of photoresist on the metal (usually silicon crystal) and then use light to erode the photoresist according to a certain circuit diagram.

Light can corrode photoresist, but not metal, so the wafer (silicon crystal) is covered with a "circuit diagram".

So how can we get the circuit diagram onto the photoresist?

The shape of the circuit is drawn on a relatively large reticle at first, and then the circuit pattern is reduced to a small size through a lens, and then irradiated on a metal plate coated with photoresist (the so-called wafer). ).

The machine used in this process is a lithography machine.

The complexity of the instrument is far beyond what people think. Now the most advanced lithography machine manufacturer in the world is ASML (Advanced Material Lithography) of the Netherlands. It can be said that there is only this relatively mature lithography machine company in the world.

Because ASML occupies more than 80% of the global market share.

The remaining market share basically belongs to Toyo. Toyo's Nikon and Canon are not pure camera companies, but have quite good IC technology, including lithography machine technology.

Of course, there are some South Korean brands of low-end lithography machine manufacturers.

Therefore, larger chip production companies must find ASML.

And the price of the other party's lithography machine is not cheap, basically tens of millions of meters to more than 100 million meters, and there is no bargaining.

Of course, ASML's technology is not developed by a technology team in the Netherlands, or developed by the Netherlands, but by the United States, the Netherlands, Germany and other countries.

Therefore, the shareholders behind ASML include Capital International, BlackRock, Intel, Shanxing, TiSMC, etc. Most of the capital comes from the United States.

Therefore, in this case, the advanced lithography machine will not be sold to Xiaguo technology companies.

Xiaxin International can buy lithography machines through some contacts in the team, but most of them are second- and third-tier products that have been eliminated.

After the wafer is covered with the circuit diagram by the lithography machine, it enters the etching machine link.

The etching machine uses chemicals to erode the areas that are not covered with the photoresist, so that the crystal surface can become the shape we want, and the chip is made step by step.

This process corresponds to the etching machine, and the technical difficulty is much smaller than that of the lithography machine.

After the establishment of Xiawei Semiconductor, the company quickly became a global top company because of the excellent technology of Yin Shen's team.

Chen Xiao felt that he could handle Xiaxin International and Xiawei Semiconductor.

The production of mobile phone chips is not a big problem, but the size and power consumption of the chips may be far behind the popular Nokia and Motorola on the market.

In fact, 2004 was the best year for Xia Xin International.

This year, Xiaxin International has been able to mass-produce 110-nanometer chips, while the tire electromechanical at this time is 90 nanometers. There is actually only a one-year technical gap between the two.

But it is precisely because of the rapid development of Xiaxin International that TiSMC and the US capital behind it are nervous, and they immediately attack Xiaxin International.

The best weapon is, of course, intellectual property infringement.

The founder and CEO of Xia Xin International, Zhang Jing, a patriotic person, used to work for TiSMC, and the high-level team also came from TiSMC.

This is not clear.

Everyone knows the story behind it. Xiaxin International lost the lawsuit and lost 200 million US dollars in cash and 10% equity of Tire Machinery. Zhang Jing left Xiaxin International.

Later, Xiaxin International's high-level turbulence was unwilling to do scientific research.

When it stabilized, the United States also realized the importance of high-end technology products such as chips, and blocked high-end equipment for chip production and research and development.

It was too late for Xiaxin International to react.

Xiaxin International's chip production technology and international level are also growing.

It is also for this reason that Chen Xiao is not willing to cooperate with TiSMC.

The purpose of TSMC doing business with mainlanders is to make money, not to help you develop.

Xiaxin International is a living example.

After helping you develop, how do you make money yourself?

If it can kill you while making money, of course I will be happy to help.

But 2004 was the best moment in the history of Xiaxin International, and it was also the best moment of Xiawei Semiconductor. It was absolutely no problem to find them to make chips.

If Changtian Technology can come up with a mobile phone chip, even if this kind of chip is a bit spicy, but it can be used and can meet the needs of consumers, then Chen Xiao can gain influence.

And Chen Xiao believes that relying on the current level of his own integrated circuit LV12 should be able to help these two companies.

Chen Xiao said to Wang Yu, "We will produce."

"You immediately prepare the relevant production data of Pangu chips, and we will go to Shanghai in a week."

Wang Yu didn't know what the boss's purpose was, and he also knew that Changtian Technology didn't have any equipment to produce chips at all.

But as a subordinate, as the leader of the lab on a chip, Wang Yu chose to follow the boss's orders.

After discussing things with Wang Yu, Chen Xiao had a good breakfast.

Changtian Technology Headquarters hired a special chef last year, not to mention the taste is pretty good.

After the meal, Chen Xiao returned to the office and worked with Song Yi to prepare for the key work to be done this time to the Shanghai stock market.

On the other hand, Wang Xiang and Li Liang, vice president of Huawei, attended the test ceremony of Mozi Communications Corporation's 3G network in Jiangzhou~www.readwn.com~ There is no agreement on the distribution of domestic 3G application rules and benefits for mobile, telecommunications and other companies. in the case of.

The country also felt that it could not wait any longer.

Therefore, the same Changtian Technology tested the use of 3G network in Jiangzhou.

This test did not participate in the company of China Mobile Telecom and Unicom, and was independently operated by Mozi Communications, a subsidiary of Changtian Technology.

All 3G base stations are built by Huawei. Because it is a test, Changtian Technology does not target all Jiangzhou users, but mainly for the student user group in Jiangzhou University City.

The student user group accepts new things faster, and is willing to cooperate with Changtian Technology in data collection, so it is a good test sample.

Mozi Communication directly opened the communication company to the next door of China Mobile and China Unicom, and announced that the 3G users who were tested would get a mobile phone card for free, and they would get a package of 50M traffic, 300 minutes of calls and 100 text messages per month.
