Siheyuan: Craftsmen of a Great Country

After the initial shock, Jiang Chen gradually calmed down.

It is impossible to find evidence for time travel, especially soul travel.

He even had some doubts as to whether the concept of time travel existed in people's minds in this era.

Now that he has understood the key point, Jiang Chen is prepared to respond to all changes with the same approach.

If you make changes rashly, it may appear that you are trying to cover up something and may reveal more flaws.

The most you can do is to be a little more restrained in the future, especially not to show any ulterior motives.

As for the surveillance by the security department, just leave it to him.

Just think of it as the security department starting to protect him again.

It probably won’t last too long, after all, Jiang Chen’s job involves dealing with too many secrets.

Long-term surveillance is actually a big problem. If information is leaked, no one can explain it.

It would also easily arouse Jiang Chen's disgust.

No matter what his current identity is, his contribution to the flower-growing family is real.

It is estimated that if no clues are found in two days, the surveillance will be withdrawn.

In other words, even if clues are found, they are discarded without reason.

If Jiang Chen really becomes rebellious because of this incident and doesn't work hard in the future, the loss will be too great.

No matter whether the cat is black or white, a cat that can catch a mouse is a good cat.

When Jiang Chen walked out of the office, he returned to his usual self, as if the previous events had never happened.

After leaving the office, Jiang Chen came to the Internet project team.

All the research here is being carried out in an orderly manner.

A team is studying the feasibility of optical fiber.

The biggest problem now is that glass factories are simply unable to produce the core and cladding required for optical fiber.

Quartz glass is not difficult to make.

The difficulty lies in the processing technology. It is really difficult for them to make such a fine concentric glass body with current technology.

The diameter of this concentric glass body is generally required to be 2-50 microns, and the diameter of the cladding is 125 microns.

Only Qiming Machine Tools can achieve this precision.

But now the first batch of supporting products of Qiming Machine Tool has been sent to the Equipment Department, and it is not their turn yet.

It is impossible to achieve with their current technology.

There is only waiting for this matter.

But their research did not stop.

They have already communicated with the glass factory and will first produce large-diameter optical fibers to conduct preliminary experiments.

Once the equipment is in place, thinner optical fibers can be made.

Optical fibers with larger diameters can also transmit signals with less loss.

As for other problems, researchers from both the glass factory and the Institute of Technology are working together to solve them one by one.

The group that Jiang Chen joined was an integrated circuit research group.

This is also the only department, besides the Equipment Department, that has obtained supporting equipment for Qiming Machine Tools.

Because the research on integrated circuits is the key to computer miniaturization.

In terms of timing, the production of integrated circuits can only be truly on track after the production of lithography machines.

But now products made with high-precision machine tools can also be used.

Especially in the current situation of single function, there are not many circuits that need to be engraved on the circuit board, so a machine tool with a precision of 5 microns is sufficient.

When the functions become complex enough and the precision requirements increase, the support of a lithography machine will be needed.

This process of improvement is the process of improving the precision of the lithography machine from low to high.

During this process, if the progress of either party lags behind, Jiang Chen will intervene to ensure rough consistency.

During this process, the lithography machine industry chain will also develop synchronously.

Similarly, the thousands of industrial chains of lithography machines do not require completion in one step.

Instead, it is gradually planned and arranged as the accuracy of lithography machines increases and requirements rise.

There have been successful cases of integrated circuits abroad, which saved Jiang Chen a lot of trouble.

Last year, Kiel in the United States created the first integrated circuit with a single circuit and won the Nobel Prize for this invention 42 years later.

At the beginning of this year, Noyce successfully developed integrated circuits by adding a layer of silicon oxide insulation on silicon wafers, and laid the foundation for modern integrated circuits based on silicon oxide.

In fact, the principle of integrated circuit is very simple.

It is to interconnect or independently embed multiple electronic components on a semiconductor chip or dielectric substrate to form a microstructure with the required circuit functions.

Simply put, it is to shrink the existing circuit components countless times and then embed them on the chip.

Its core function is to enable electronic components to move towards miniaturization, low power consumption, intelligence and high reliability.

Although the principle is simple, the first person who thought of this method must be a genius.

Generally speaking, the technological content of high-tech products with relatively simple principles is often a reflection of the industrial foundation.

If it were before, the flower growers would naturally have no choice but to admit defeat.

But now, the most advanced and precise machine tools are in China, and China has been leading the world in comprehensively deploying the lithography machine industry chain for 20 years.

Perhaps our industrial base in other areas is still weak, but when it comes to precision, we are unmatched.

Although many things cannot be accomplished solely by high-precision machine tools, integrated circuits are an exception. The core of them is precision.

The higher the precision, the more accurate it is, the smaller it is, and the higher the integration.

The Institute of Technology tried every possible means to get a piece of silicon integrated circuit to provide a reference for everyone's research.

However, by now, this integrated circuit has already been dismembered and studied.

Now, they are trial-producing integrated circuits with the support of Qiming Machine Tools.

Because the functions of computers in this era were still very simple, integrated circuits were not complex and the degree of integration was not high, the production difficulty was relatively low.

It is estimated that they will be able to produce the first version of the trial integrated circuit soon.

This progress excited the original computer researchers in the group.

They had previously studied computer manufacturing, so they certainly knew how much change this integrated circuit could bring to computers.

According to their estimates, the size and weight of computers with integrated circuits can be reduced by at least dozens of times.

That is, it is reduced from the original 30 tons to about 1 ton.

This is still a huge thing for Jiang Chen.

But for them, they are children who have become as thin as their mothers who have suffered a lot from working away from home.

Jiang Chen also said that this was just the initial version.

Once new manufacturing tools come out, not only will the size of the central processing unit be reduced again, but more extremely tiny but powerful units can be accommodated in an even smaller volume.

The computer weighs only a dozen pounds, but has more and more powerful functions.

At first they didn't really believe it.

But as the integrated circuit took shape, they discovered that anything was possible.

Maybe it is really possible to achieve the goal that Jiang Chen mentioned.

If computers could be miniaturized, it would change many industries.

Then they remembered what Jiang Chen said, "Computers can change the world." This was not just an empty slogan, but a real possibility.

But before that, there is still a long way to go.

Especially given the current national conditions, even if the research and development of this system is completed, there is no soil for it to germinate.

When Jiang Chen arrived, some engineers were using Sangang machine tool's supporting machinery to make small circuits.

Very focused.

Jiang Chen did not disturb him, but stood quietly behind him, using his eagle eyes to watch his work.
