Chapter 226 The powerful understanding of unmanned automatic buses

28nm lithography machine.

28 nanometers are already the top level of domestic lithography machines in Yanguo.

In the current global lithography machine market, ASML, Canon and Nikon are the three largest suppliers, and they occupy 99% of the global market share.

Canon and Nikon mainly produce 22nm "low-end" DUV lithography machines, while most ASML products are higher-end EUV lithography machines.

The actual difference between DUV and EUV is the light source. DUV refers to "deep ultraviolet rays", and EUV refers to "extremely deep ultraviolet rays". You can feel that EUV technology is more awesome by listening to the name.

The same is true. The light source wavelength of the DUV lithography machine is 193 nanometers, and the EUV light source wavelength is 13.5 nanometers. Moreover, the EUV light source is not a natural light on the earth. It requires specific technologies and equipment to be manufactured.

Under the principle of shorter the wavelength of the light source, the greater the refractive index and the greater the energy, DUV light sources with a light source wavelength of 193 nanometers can generally only achieve a 25-nanometer process. Inet has achieved 10 nanometers with the workbench mode, but it will never be able to make any breakthroughs in the future.

10 nanometers.

Taijiu Electric has also forced the production of the first generation of 7-nanometer chips with DUV light sources, but it is achieved through multiple exposures of DUV. Not only is the process complex and the yield rate is low. In fact, the so-called 7-nanometer still has a lot of moisture, Taijiu Electric is also

When the second generation of 7nm chips were replaced with EUV light sources.

In other words, the process of DUV light source is OK to make 28nm and 56nm, but it involves 7nm and 5nm. There is almost no chance for DUV, and it can only rely on EUV technology.

Now, ASML is the only supplier in the world that can produce EUV lithography machines!

It is no exaggeration to say that ASML has completely monopolized the global mid-to-high-end lithography machine market with EUV technology. According to the latest year's sales, ASML's lithography machine accounts for 91% of the market share, Nikon 6% and Canon only 3.

%.

Phoenix Group's 28-nanometer lithography machine produced by Shanghai Microelectronics (SMEE) in Yanguo is of course just a DUV light source, but even the "low-end" DUV technology is very rare.

In fact, although the Shanghai microelectronics factory has achieved mass production of 28nm lithography machines, it has been limited by production capacity, with a production capacity of only two or three units per year. Before Phoenix Group, only three companies have obtained domestic production of microelectronics.

Phoenix successfully obtained the 28-nanometer lithography machine under the operation of Gaoling Capital.

Hu Lai was already very satisfied.

Phoenix will soon have its own 28nm lithography machine. Although the process is not very advanced, as long as the 28nm lithography machine is successfully installed and produced, Phoenix Semiconductor will truly become a vertical integrated semiconductor integrating design, manufacturing, packaging, testing and sales.

company!

Such an IDM model undoubtedly provides strong guarantees for the chip security of the entire Phoenix Group!

...

News from America began to spread.

In the following time, the threat ban on the Internet caused another national discussion because of the American threatening to tear each other. This time, Phoenix Group, which was in the vortex, did not speak out again.

At this time, Hu Lai had devoted himself to the installation and debugging of the 28-nanometer lithography machine transported by the microelectronics factory. After he personally participated in the lithography machine supporting installation project, he truly realized why the lithography machine is on the crown of the semiconductor industry

The pearl.

The Shanghai microelectronics factory is very professional. After confirming the order for Phoenix lithography machine half a year ago, it notified Phoenix Group to make corresponding preparations for the lithography machine factory half a year in advance.

The entire factory where the lithography machine is parked has been specially reinforced. Even special places have been suspended. The purpose is that the lithography machine is very sensitive to vibration. Slight vibration will cause light source errors, resulting in batches of

All wafers are scrapped.

Not only the stability of the foundation, but all lighting in the factory produced by lithography machines have specified requirements. The white light we usually use cannot be used, but yellow light sources with longer wavelengths are required.

Because photoresist is very sensitive to short light, using a yellow light source with a long wavelength is like turning off the light for wafer manufacturing, and the principle is like exposing the film.

In addition to these, the lithography machine production plant also has particularly high requirements for air quality, and the air quality needs to reach the ISO level 1 or 2 level. Such air quality is ten thousand times cleaner than the air environment requirements of medical operating rooms...

To meet such requirements, it is necessary to use a large amount of advanced fully automated mechanical operation and efficient fan filtering units for 24-hour uninterrupted ventilation and filtration.

Apart from these harsh requirements, what makes people sigh is that there are more than 30,000 parts of the lithography machine and the powerful power consumption required to manufacture light sources...

but.

Fortunately, although the Shanghai microelectronics factory is only a lithography machine manufacturer, it is still well prepared for the entire set of lithography machines.

Although the factory's fan filter unit (FFU) and filter filter elements cannot be produced domestically for the time being, such as the domestic photoresist effect is not satisfactory, with the private help of microelectronics, the assembly and related supporting facilities of the Phoenix 28-nanometer lithography machine are still

Completed in an orderly manner.

In the words of the manager responsible for the project of Shanghai Microelectronics, the microelectronics factory can find a way to help secretly for the first batch of supporting equipment and materials, but after the Phoenix Semiconductor is put into production, subsequent changes and upgrades of filter elements and photoresist materials are followed.

The source is the internal affairs of Phoenix itself.

Hu Lai is already very satisfied.

No matter how difficult the photoresist is, the fan filter unit and the filter element are, how difficult it is to pass through the lithography machine? As long as the most difficult problem of lithography machine is solved, the other supporting facilities are a matter of time!

soon.

The 28-nanometer lithography machine provided by the Shanghai Microelectronics Factory has officially settled in Phoenix Semiconductor, and Phoenix Semiconductor has also begun to truly have the ability to produce chips.

While introducing a large number of advanced chip personnel, the research on the supporting industry chain of 28-nanometer lithography machines has also been quietly launched within Phoenix Group...

Fan filter units, filter elements, photoresist and other projects have been further invested in research and development. This time, not only Phoenix cooperates with existing domestic companies, but Phoenix Research Institute has also begun to invest a lot of money to start special research.

Hu Lai is now much more confident than before. Now Phoenix Group can really solve these difficulties by spending money and regardless of cost.

He has been busy arranging one by one work on supporting 28nm lithography machines. After Hu Lai finished this time, the strongest blockade and restrictions imposed by the Americans on "stacking technology" also showed strong pressure.

In the office of Hu Lai, Director Zhang was not in a high mood.

"Boss, it's been a month since the United States issued a ban."

"In the past month, all chip design companies that have obtained our 'stacking technology' license have recently stated that they will not launch chips with our 'stacking technology' for the time being. They have secretly expressed their concerns about the ban on the American countries."

"Yesterday afternoon, Huawei Group also contacted us and clearly stated their concerns. They hope to maintain technical communication with us and hope that we can understand their difficulties."

After saying that, Director Zhang sighed, obviously feeling a little discouraged.

Hu Lai was very understanding. When Yan Country was blocked by the American countries, he felt such pressure personally.

"Old Zhang, our Phoenix Group has good cash flow and has different businesses in various industries. She is still under pressure for the American blockade, let alone these main businesses are the chip industry, and there is no way to resist risks at all.

It's a small company."

"I'm on the list today, and the bank will take out their loan tomorrow, and some people will change jobs within the company the day after tomorrow. Maybe even the company will be gone in a few days."

“In such cases, it would be wise to choose not to use our ‘stacking technology’.”

Director Zhang knew in his heart that the truth was the case, but whenever he thought about it, he still felt a little cowardly. This is why the entire chip industry is controlled by others!

Hu looked at Director Zhang's disappointed look and felt helpless.

Although Phoenix Group currently has a 28-nanometer lithography machine, if it really wants to achieve the rise of the domestic chip industry, it is necessary to add at least 14-nanometer lithography machine to "stacking technology".

Hu Lai entered the system a few days ago and saw that he benefited from the sales of Phoenix laptops and all-in-one computers during this period. The points in the system have reached more than 10 million points. If this continues, you can get five in a year.

Purchase a 14-nanometer lithography machine with tens of millions of points.

Hu Lai was about to comfort her, but Director Zhang quickly adjusted herself.

Director Zhang looked at Hu Lai and did not continue to talk about chips. Instead, he handed Hu Lai a stack of documents in his hand:

"Boss, let's not talk about chips."

"Do you still remember an unmanned automatic bus project arranged in the city before?"

Hu Lai was stunned, and after a moment of thought, he immediately reacted.

I remember that Gao Ming personally found himself half a year ago. First, he purchased a batch of Phoenix "Stone" all-in-one machines, and second, he hoped that Phoenix Automobile could design a "unmanned automatic bus" for Shancheng Bus Group, specifically

Used for nightly unmanned buses.

At this time, when I heard Director Zhang suddenly mention it, is there any progress?

He curiously took the information handed over by Director Zhang, and asked while looking down:

"Lao Zhang, is there any progress?"

As soon as he finished speaking, his eyes were attracted by the information in his hands the next moment.

I saw that the first page of the information was a real-life photo shoot, which happened to be a bus picture.

The bus in the picture looks completely different from the buses on weekdays.

The entire bus uses green and white, and it looks like a new energy vehicle at first glance.

However, the entire bus does not adopt the square shape of a common bus, but instead designs the entire body very round, and the length of the entire bus is only about half of the length of the ordinary bus.

Director Zhang showed an interesting look at Hu Lai at first sight, and finally a smile appeared on his face:

"Boss, this is a project designed by our Phoenix Automobile specially established 'Unmanned Transit Project Team'."

"We had previously considered using BYD electric bus K7 technology, after all, we are strategic partners with BYD."

"But in the actual test later, because the length of BYD K7 reached 9 meters and the width was 2.3 meters, using unmanned autonomous driving technology on such a large bus, the safety and calculation amount required for autonomous driving are all the same.

It was very big, so we finally chose a smaller design."

"We designed this small bus with a length of 6.5 meters, 2 meters and a height of 2.8 meters, and its length is about the same as a small minibus."

"In this way, this small 12-seat 'unmanned automatic bus' can not only perfectly adapt to the 'automatic unmanned driving technology' of urban roads, but also ensure 100% risk and safety judgment at a speed of 50KM/H per hour, but also

This makes this 'unmanned bus' application scenario more appropriate 'unmanned bus at night'."

"Even, this unmanned bus can be used as a supplement to ordinary buses during the day; when dispatching during peak hours of work can not only reduce the operating costs of the bus company, but also place various routes."
