The ups and downs of life in the Siheyuan

Representative Tong tried hard to suppress his excitement, "It's done, it's done", he kept shouting in his heart.

He spent half a year in agony.

Every time he returned to the unit, there were a bunch of big guys waiting for him, asking about the progress of the chip.

Today, he was finally free. He believed in Li Yuan and even more in the machine in front of him.

The mechanical part of this photolithography machine was jointly built by Xiao Gong and Li Yuan, and its processing accuracy has surpassed the most precise measurement tools in the country.

To improve accuracy, the two worked together to machine a set of gauge blocks.

The gauge block is not a standard size, it is just to ensure a tighter fit between components during processing.

Therefore, they defined the gauge blocks as No. 1 to No. 10.

No. 1 is the smallest and is designed to be 1 micron in size.

No. 2 is the second, and the size is designed according to 5 microns.

接着顺序为10微米、50微米、100微米、200微米、500微米、1毫米、5毫米和10毫米。

The material is tungsten carbide synthesized by Li Yuan by constantly adjusting the proportions in the crucible.

Metal cobalt is then used as a binder to synthesize larger gauge blocks.

As for the raw materials, Representative Tong helped prepare them.

In 1958, geologists discovered the Jinchuan copper-nickel sulfide deposit in the vast Gobi desert in the Hexi Corridor of Gansu Province.

In one fell swoop, it broke the "nickel blockade" of Western countries and got rid of China's label as a "nickel-poor country".

In June 1959, the Ministry of Metallurgical Industry decided to establish Yongchang Nickel Mine; in January 6, it was renamed Jinchuan Nonferrous Metals Company (referred to as "Jinchuan Company").

This is where the materials come from.

With the gauge block and the vernier caliper, the problem of machining accuracy is solved.

Coupled with Li Yuan's special control chip, a precision automatic control pallet system is manufactured.

Of course, current dedicated chips can only correspond to fixed-size wafers.

Current chips can only process 4-inch wafers.

The wafer size could have been set, and the control algorithm was relatively simple.

But in order to rush for time, we directly designed it to a fixed size.

I will use it like this for now, and then I will design a control chip with adjustable wafer size when I have more time.

If time permits, simply design a CPU to improve laboratory work efficiency.

Given the current situation, I guess there won’t be that much time.

Of course, all other supporting materials currently used, such as photoresist, etching fluid, cleaning fluid and other materials, were developed by Li Yuan and Huang Yan's team.

In order to keep up with the schedule, we had to suspend wafer preparation research and instead fully join the research on chip manufacturing equipment and related materials.

In just six months, everything was accomplished because Li Yuan secretly took action from time to time.

Or provide ideas directly.

If that doesn't work, try it yourself.

Therefore, Li Yuan, as the general person in charge of chip manufacturing equipment, is also the chief technical engineer.

He is like a treasure house. Even if it is the most difficult bone to crack, just ask Li Yuan and he will give the answer in a short time.

During the research process, the most common scene is, "Old boy, help me get this information..."

Once he got the information, he began to study and deduce like crazy.

In short, the answer will be given in the end.

In fact, he already had the answer in his mind. The reason why it was so complicated was also a means of self-protection.

Just like now, his image in everyone's eyes is that of a man with strong learning and analytical skills, great luck, and blessing from God.

Closer to home.

When the lithography machine was operating normally, Representative Tong kept giving a thumbs up to Li Yuan through the double-layer glass.

He got excited, greeted Li Yuan, and ran out of the laboratory.

He once again forgot the fact that there was a phone in the laboratory, and instead ran back to the unit out of habit.

The next day, there were a few more people in the laboratory, including superior leaders, leaders of the National Defense Industry Office, and related assistants.

**The National Defense Industry Office was approved and established in 1961 and is responsible for the management of the entire military equipment plan.

Organize collaboration among various equipment work departments within the military to coordinate and resolve major and common issues in equipment work.

This is the first visit by a leader of this organization.

Superior leaders still attach great importance to it.

When Li Yuan reported the project progress to him and mentioned the product quotation, his superiors were secretly delighted.

The middle-aged man in his 50s in front of him, although younger than him, was accompanied by his superiors throughout the process.

“If I hadn’t seen it with my own eyes, it would be hard for me to imagine that our country actually has such advanced equipment.

Not to mention its technical content, the appearance design is also quite impressive.

Only with this spirit of excellence can we develop world-leading high technologies."

The leader of the National Defense Industry Office was delighted from the bottom of his heart. Looking at the equipment in front of him, he thought of the anti-artillery radar.

Once it becomes an organically equipped unit, the overall strength of the Chinese Army will definitely be raised to a higher level.

In the following discussion, the leaders of the National Defense Industry Office put forward some other needs and hoped that the laboratory could study them.

“Now we have anti-artillery radars, but we lack technical aircraft, air-to-air missiles, and surface-to-air missiles.

I think these fire control systems can be replaced with chips.

Therefore, your laboratory has great potential."

"Listening to you, I know that you are a leader who understands technology." The superior leader flattered me.

"I was forced to do it. The troops were clamoring for it. After listening to it too much, I only got a rough idea.

Recently I obtained an air-to-air missile from South Vietnam. After dismantling it, I found that a lot of transistors were used in it.

I think since transistors can do it, more advanced chips are more suitable."

Li Yuan had to admire these senior leaders. Putting aside their management abilities for the moment, their technical sensitivity was worthy of praise.

"Yes, several leaders, chips will enter all walks of life in the future.

Today's computers are characterized by high power consumption, poor reliability, and large footprints.

The transistor computers being studied by various units have been perfectly solved in terms of power consumption, reliability and floor space.

Think about it, everyone, it has only been so long since our country had electron tube computers that it will soon be eliminated by transistor computers.

In the near future, more powerful chip computers will replace everything now.

And chips will definitely enter all walks of life, especially military equipment."

A few words of emotion from several leaders led to a long sales pitch from the young man in front of them.

But upon reflection, they felt that this inference was indeed inevitable.

Several people looked at each other, and the leader of the National Defense Industry Office said: "Perhaps it is because of your unique vision as a leader that you created the laboratory in front of you."

Several leaders left excitedly, and the superior leader got what he cared about: the military agreed to the laboratory's offer.

Next, Li Yuan's main job is to study the turbojet-6 engine.

Although I knew all the design information by heart, I never triggered the skill book.

It seems that the system can only be triggered when you have to start optimizing the engine with your own hands.
