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

The market is becoming increasingly fierce.

Flip phones have been made, and slide phones have begun to appear, which makes those mobile phone manufacturers have no time to be distracted from the field of touch screens.

In addition, today's customers, they are more concerned about whether the mobile phone is sturdy and durable, whether the battery life is long, and other "quality" issues, so no one will waste time and money to consider manufacturing mobile phones that the market does not look up to.

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

This is because it not only accumulates experience, but also accelerates technological innovation.

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

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

Including some details of the cooperation with Sony.

It is not easy to overcome the technical barrier of at least ten years.

The operating system of a mobile phone alone is not generally difficult.

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

In the end, after research and discussion, the computer department decided to start with the simulation.

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

Copycat is always the fastest way to catch up with the other party's technology.

They found a new mobile phone co-developed with Symbian, and were going to first dissect the kernel of the Symbian system, and then try to design a simple operating system, and finally improve it....

At this time, due to the easing of the relationship between Infinity and the Institute of Precision Research, many researchers returned to the laboratory one after another.

They were so happy that they couldn't close their mouths, and they were all praising each other, but Chen Jie was generous.

Then, they went headlong into the lab and continued their research that they hadn't done before.

It stands to reason that these "outsiders" have to charge for using the company's instruments, but Chen Jie learned through Zhao Gong that the Precision Research Institute is simply poor, and the annual funding is only seven or eight million.

This made him really embarrassed to ask for money.

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

His primary goal now is to design a chip drawing, 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 same size as a thumbnail cover.

And this is not only the CPU structure, other structures such as GPU, NPU, ISP, DAC decoding chips, baseband, etc. are all among them.

Designers need to line up billions of transistors in this nail-sized area and make them work accurately.

Precision is like carving an entire city with a pen.

A chip needs to go through about 2 steps from the drawing stage to the physical stage, which are chip design and chip manufacturing.

Building a chip is like building a building, and designing a chip 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 early, and they made the world's first chip.

Chips are products of the semiconductor industry, and semiconductors are the materials used to make chips.

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

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

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

In the world, only 3 countries have the ability to manufacture lithography machines, among which only island countries and the Netherlands can manufacture high-end lithography machines.

Although the island country is small in size, it has a strong scientific and technological strength and industrial base.

In the eighties, the island nation's lithography machines were the most advanced in the world.

At that time, Nikon and Canon could also produce lithography machines, which once occupied more than 50% of the industry, and 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 nation ceded the crown of the lithography machine giant to the Dutch ASML.

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

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

At that time, ASML was still a small company, and in the face of the island country's domination of the lithography machine market, they decided to overtake in corners and try the "immersion lithography machine technology" proposed by TSMC and Lin Benjian.

This technology, which you may sound like is very high-end, is actually a very simple technology, so simple that when Chen Weidong first heard about it, he thought he had heard it wrong.

So he was impressed by it.

Immersion lithography technology is to fill the lithography lens with liquid between the silicon wafer to be engraved, which can greatly improve the processing accuracy of the lithography machine!

Chen Weidong told Professor Krueger about this "technology".

In recent days, he has successfully engraved a dense pattern of 105 nanometers with the lithography machine he brought back from the Treehouse Research Institute, a lithography machine with an accuracy of 190 nanometers!

He was ecstatic about the result!

Almost out of shape!

A typical lithography machine does not have any obstruction between the lithography lens and the silicon wafer.

Of course, from another point of view, there is air between them.

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

Since 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 subtle engraving.

Originally, they thought that there were some old lithography machines, but suddenly they turned into 105 nanometer lithography machines, far exceeding the existing lithography technology!

In fact, this immersion lithography technology is not the first of its kind in ASML.

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

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

Therefore, the mainstream lithography technology research in this period only used it as a transitional means, and did not pay enough attention to it.

Once the next generation of lithography technology matures, it will not hesitate to abandon immersion lithography.
