God-level Trader of Rebirth

Chapter 181 Immersion Technology

During this period, the competition in the mobile phone industry is rapidly forming.

The market is getting more and more intense.

Flip phones have been manufactured, and slider phones have also begun to appear, which makes those mobile phone manufacturers have no time to distract themselves from researching the field of touch screens.

In addition, current customers are more concerned about whether the mobile phone is durable, whether the battery life is long, and other "quality" issues, so no one will waste time and money thinking about making mobile phones that the market does not like.

The idea put forward by Chen Weidong is not good-looking for Sony, but for the sake of his "huge money", they are still happy to accompany him to go crazy.

Because this can not only accumulate experience, but also accelerate technological innovation.

No matter how you look at it, it's a win-win situation.

After leaving Sony, Chen Weidong immediately called Chen Jie and explained to him the preparations needed in the early stage.

Including some cooperation details with Sony Corporation.

It is not an easy task to overcome the technical barriers of at least ten years.

Just the operating system of a mobile phone is not so difficult.

Although Infinity Computer Company has thousands of excellent programmers, they are good at application software development, and they are completely blind to how to design a mobile phone operating system.

Finally, the computer department decided to start with imitation after research and discussion.

Otherwise, it will take a lot of time to start from scratch and just explore.

Copycats are always the fastest way to catch up with the opponent's technology.

They found a new mobile phone jointly developed with Symbian, and they planned to analyze the kernel of the Symbian system first, then try to design a simple operating system, and finally improve it
At this time, due to the easing of the relationship between Infinity Corporation and the Precision Research Institute, many researchers returned to the laboratory one after another.

They were so happy that they couldn't close their mouths, they were all praising Chen Jie for his generosity.

Then, they went straight into the laboratory and continued their unfinished research.

Logically speaking, these "outsiders" should be charged for using the company's instruments, but Chen Jie learned through Mr. Zhao that the Institute of Precision Medicine is really poor, and the annual funding is only 8 million.

This also made him really embarrassed to ask for money.

Professor Kruger also had many discussions with Chen Jie and others in the past month, and finally determined the research direction.

His primary goal now is to design a chip blueprint, which is very difficult and requires the cooperation of many people.

A small chip gathers the wisdom of all mankind. In fact, even the United States cannot fully grasp all the links.

The area of ​​a mobile phone chip is basically only about 10 square millimeters, which is about the size of a thumbnail.

And there is not only the CPU structure, but other structures such as GPU, NPU, ISP, DAC decoding chip, baseband, etc. must be included in it.

Designers need to arrange billions of transistors in this fingernail-sized area and make them work accurately.

Precision is like using a pen to carve an entire city on it.

A chip needs to go through two steps from the drawing stage to the physical stage, namely chip design and chip manufacturing.

Building a chip is like building a building, and chip design is like designing architectural drawings for a building.

The United States has an absolute advantage in the field of chip design.

Their semiconductor industry started the earliest, and they manufactured the world's first chip.

A chip is a product of the semiconductor industry, and a semiconductor is the material used to make a chip.

This industry, in layman's terms, is called the chip industry, and in academic terms, it is called the semiconductor industry, which is actually equivalent to the difference between potatoes and potatoes.

It is not enough to just design a chip, he also needs to use a lithography machine to engrave the chip.

The lithography machine is equivalent to the "pen" for engraving.

In the world, only three countries have the ability to manufacture lithography machines, and among them, only island countries and the Netherlands can manufacture high-end lithography machines.

Although the land area of ​​the island country is small, it has a strong scientific and technological strength and industrial foundation.

In the 80s, the lithography machines in the island country were the most advanced in the world.

At that time, Nikon and Canon were also able to produce lithography machines, and once occupied more than 50% of the industry. Major customers, including IBM, Intel, and Texas Instruments, all rushed to buy their lithography machines.

However, due to a mistake by these two companies, the island country ceded the crown of the lithography machine giant to ASML in the Netherlands.

ASML began to develop EUV lithography machines around 2000 and decided to mass-produce them.

At that time, the lithography machine companies in the island country thought the system was too complicated and did not choose to follow up.

At that time, ASML was still a small company. Facing the dominance of the lithography machine market by the island country, they decided to overtake the others with a small and broad, and try the "immersion lithography machine technology" proposed by TSMC and Lin Benjian.

This technology sounds high-end to you, but it is actually a very simple technology, so simple that when Chen Weidong heard it for the first time, he thought he had heard it wrong.

So he was very impressed with this thing.

Immersion lithography technology is to fill the gap between the lithography lens and the silicon wafer to be engraved with liquid, which can greatly improve the processing accuracy of the lithography machine!
Chen Weidong told Professor Kruger about this "technology".

In recent days, he used the lithography machine brought back from the tree house research institute in the experiment, the lithography machine with a precision of 190 nanometers, and successfully carved a dense pattern of [-] nanometers!

This result made him ecstatic!

Almost gaffe!
In the usual lithography machine, there is no shield between the lithography lens and the silicon wafer.

Of course, from another perspective, there is air between them.

The idea of ​​immersion is to replace the air in the middle with liquid.

Because the liquid has a refractive index, when the ultraviolet light passes through the liquid medium, the wavelength of its light source will be shortened, thus playing the role of fine engraving.

Originally, they thought that the lithography machine was a bit old, but it suddenly changed into a [-]nm lithography machine, which far surpassed the existing lithography technology!
In fact, this immersion lithography technology is not ASML's first.

As early as the early 80s, some scientists used immersion technology to successfully improve the photolithography effect.

However, with this technology, its liquid can easily contaminate optical lenses.

Therefore, the mainstream lithography research in this period only regards it as a transitional method, and does not pay enough attention to it.

Once the next-generation lithography technology matures, immersion lithography will be abandoned without hesitation.
