Siheyuan starts from a better life

Chapter 789, the first chip

Actually! At the Academy of Sciences, they have also been paying close attention to the development progress of lithography machines.

When they learned that Jiang Yan needed to make a mask, they immediately organized their full support.

At present, the place with the highest science and technology in the country is undoubtedly the Academy of Sciences. In order to shorten the project, Jiang Yan specially held several meetings with them. Among them, the Academy of Science and Technology of the mask said that they would be responsible for it.

They are naturally quite clear about the benefits brought by the third generation of computers. They also know that chips are the top priority. In order to produce them as quickly as possible, the Academy of Sciences has gathered experts and scholars from multiple departments. After a long period of time, they Constantly providing suggestions on the material formula, production process and quality control of the mask, ultimately helped Jiang Yan successfully break through this core technology.

So after the mask was prepared, Jiang Yan began to make the photolithography pattern. There are no automated machines now, and photolithography patterns must be carved manually. This requires very high requirements for workers, because they must carefully control every detail of the pattern exposure in one go, without stopping in the middle.

"Everyone, I'm going to start photolithography of the first test chip now." Jiang Yan calmed down and said solemnly.

Hearing Jiang Yan start carving, everyone in the workshop didn't dare to express their anger.

I saw Jiang Yan carefully putting the prepared silicon wafer into the lithography machine, then starting the equipment and debugging the parameters meticulously. The first batch of photolithographic chips was a processor chip for machine tools designed by Jiang Yan himself, because he was quite familiar with this thing.

The process used by the current lithography machine is the most cutting-edge one-micron process. This process can be said to be a very advanced process now. Of course, compared with the chips made by Jiang Yan in his previous life, which were often made with a few nanometer process, the performance of this micron chip is still poor. There is a huge gap, but for this era, reaching this level of craftsmanship is a very good achievement.

However, the birth of this micron chip marks that my country's integrated circuit manufacturing has entered the international advanced ranks, laying a solid foundation for subsequent development.

In the following time, Jiang Yan patiently completed the work of pattern exposure with a focused look and did not dare to be careless at all. His head was gradually covered with sweat, but he didn't have time to wipe it off now.

Others gathered around the operating table, stretching their necks, nervously waiting for the chip to be born.

Half an hour later, Jiang Yan was still focused on controlling the lithography machine and completing the exposure work meticulously.

"Okay, it's done."

After Jiang Yan completed the last stroke, he immediately turned off the power.

Looking at the formed chip, Jiang Yan let out a satisfied smile.

"Okay, now we just have to wait for the results." He exhaled softly and turned off the power switch of the device.

"Comrade Jiang Yan, what is the possibility of successful chip engraving?" As soon as he saw Jiang Yan turning off the power of the lithography machine, Professor Wang stepped forward, handed Jiang Yan a towel, and asked with an anxious look on his face. .

"More than 90% sure." Jiang Yan wiped his sweat and replied with a smile on his face.

Even though he said this, Jiang Yan still didn't feel low in his heart.

After waiting for a few minutes, the exposed silicon wafer is gently removed from the photolithography machine.

Jiang Yan carefully placed the chip on the operating table, then picked up a magnifying glass to carefully examine the pattern.

Jiang Yan murmured to himself, "The pattern is very clear, which means that the circuit image has been formed!"

"Is it true? Our chip engraving was successful the first time?" Since Professor Wang was the closest to Jiang Yan, he naturally understood what Jiang Yan was saying to himself, so he subconsciously asked. . "Success, under the magnifying glass, the circuit pattern has been revealed!" Jiang Yan said excitedly.

"Come on, Professor Wang, come and take a look!" After Jiang Yan said this, he grabbed Professor Wang next to him and put the magnifying glass in his hand.

After Professor Wang took the magnifying glass, he carefully began to look at the completed chip.

“The circuit pattern is so clear, it’s incredible!”

"It's hard to imagine the thin lines on this. Is this the circuit of the chip?"

“Such a detailed image can be carved into something so small!”

Professor Wang was watching and admiring, which made everyone scratch their heads and want to find out more.

"Get in line and take your time, we all have time." Seeing this situation, Jiang Yan could only say helplessly.

"Xiao Jiang, what is the use of this small chip?" Wang Honghai asked confused.

This thing was still too advanced for him, and he couldn't understand it.

"That's right, it looks like just a pattern, what can it do?" Zhao Zhanqiang next to him also looked at Jiang Yan curiously.

"This chip is not simple!" Jiang Yan said with a smile, "It integrates computing and control circuits, which can realize digital control and efficient computing of machine tools. In layman's terms, this chip is like a small 'brain'. Once installed on a machine tool, the machine tool can operate automatically like a human being.”

"For example, lathes that previously required manual control can automatically process parts according to the program after installing the chip. The accuracy is higher than manual operation. It can also realize functions such as automatic drawing and automatic control of motor speed. In this way, the machine tool changes from a simple machine to a It has become an intelligent machine!”

After hearing this, the two people suddenly realized.

"Xiao Jiang, you mean that this thing can allow us to enter the four modernizations in advance."

Jiang Yan didn't know what to say when he asked this question, but there was nothing wrong with him asking. Jiang Yan could only express vaguely that it was of great significance to the promotion of the four modernizations.

It's not that Jiang Yan doesn't want to go into detail. If he wants to go on in detail, he probably won't be able to finish it in three days and three nights. Just like Jiang Yan is introducing to them the smart phones, smart watches and personal computers of later generations. They I thought it was science fiction.

This small chip represents the widespread application of electronic technology in machinery manufacturing. In the future, we must continue to improve the yield rate of chip manufacturing and design more advanced and powerful chips. This is the key to sustainable development.

The birth of the first chip marked that my country's semiconductor technology has entered a new stage of development.

As long as we work unremittingly, we will be able to gradually narrow the gap with foreign countries and eventually move towards the ranks of the world's manufacturing powers!
The application of chips will also bring about revolutionary progress in electronic information technology in various fields. In the future, the development of computers will also accelerate as a result. At that time, powerful tools to improve production efficiency and improve people's lives will appear!
Although the road is long and hardships still lie ahead, history has taken its first critical step.

Simply put, this time Jiang Yan witnessed a piece of history.
