The Grandmother in the Siheyuan

Chapter 208: Jiuxian Bridge

"From what angle?"

"These students helped us, greatly shortened our research cycle, and saved a lot of money in the end. Just give them a little bit and treat it as a bonus."

Director Huang shook his head like a rattle: "Impossible, impossible, there is no precedent for this in the past."

"Or you can just recruit an apprentice and pay him an apprentice's salary."

Director Huang is very principled and he refuses to do this or that. First of all, Liu Hua must affirm that Director Huang is absolutely a good director and he cares very much about the students. The reason why he refuses to do this or that is because we have not completely let go and everything must be done in accordance with the regulations.

"Too rigid." Liu Hua and Professor Li complained: "We don't care anyway, Director Huang, these kids are on vacation and don't even go home to help us do experiments. You can't let them pay for their meals, right?"

Director Huang was finally forced into a corner and had to squeeze out some money from the limited funds, nominally to repair the dormitories. He treated these students as laborers and gave them some subsidies.

Although the money is not much, it is enough for students' daily use so that they don't have to pay money to help the teachers.

At the beginning of August, Liu Hua took all the students to Jiuxianqiao, which is the semiconductor production park in Beijing and where most of the electronics factories in the north are concentrated.

After coordination with the Ministry of Science, Liu Hua and his team will modify a photolithography machine here to manufacture ultra-large-scale integrated circuit chips.

Looking at the lithography machine in front of him, it is completely different from the ASML lithography machine that Liu Hua has in mind. It has a strong heavy metal industrial style.

"We have completed the ninety-nine bows, and the only thing left is the last step." Professor Li said with a smile: "To be honest, I am still a little nervous. I don't know if our design can produce ultra-large-scale integrated circuits."

"Forget it, just do it." Liu Hua said with a smile: "First of all, we have to have confidence in ourselves."

The student asked curiously: "Teacher, why do you always have so much confidence?"

"Because there is nothing I, Liu Hua, cannot accomplish."

If this happened thirty years later, King B would definitely be ridiculed by the crowd, but in this era, such confident words are enough to stabilize the morale of the troops.

With Liu Hua's confidence, everyone worked hard and completed the transformation of the lithography machine in just over half a month.

It was worth it that Liu Hua spent a thousand points to exchange for the knowledge of lithography machines. Of course, general knowledge of lithography machines could not be so cheap. What Liu Hua exchanged was only the knowledge of basic lithography machines, but it was enough for use at this stage.

The transformation of the lithography machine was completed, and Factory 798 even set up a table for Liu Hua and his team to celebrate. The director of their factory knew very well that the problem was not solved yet.

Although this is not the achievement of our own factory, after the transformation, you cannot move the lithography machine away. The final user can only be Factory 798. Since we are the ones who get the benefit, we might as well be generous to these technicians.

"Now everything is ready, we just need a favorable wind." Liu Hua said to Professor Li with a smile: "We have spent half a year to accumulate theoretical knowledge, and we have also designed the ultra-large-scale integrated circuit. Now the only thing left is to produce it."

"I still feel like I'm in a dream. I thought this work would take at least three to five years." Professor Li said in disbelief, "I didn't expect it to be almost done in half a year. Why does it feel so unreal?"

Factory 798 has a team of mature technical workers. With their assistance, it took less than half a month for the first VLSI chip to be produced. Thanks to Liu Hua's mature guidance, the first tape-out was successful, and the next step was the tense testing phase.

Liu Hua and Professor Li were conducting intensive tests in the laboratory, while the rest of the people were waiting outside. Even though Liu Hua asked them to take a rest, no one was willing to leave.

After more than half a year of hard work, it all depends on the final result. No one wants to know the result later than others.

It was the middle of the night and most of the lights in the laboratory were turned off. At that time, our country had not yet carried out large-scale infrastructure construction and electricity was still a scarce resource. Except for some key factories, no one could guarantee that they had not experienced power outages.

With a click, the laboratory door was opened. The students, who were sitting, standing or squatting, looked towards the laboratory door sensitively.

Liu Hua and Professor Li held up a document of only a few pages and said, "Students, I have good news for you. After six months of intense work, our first VLSI chip has finally been successfully developed."

In fact, the second sentence had already ignited the enthusiasm of the students. The deserted campus suddenly became lively. It was because the campus of Huaqing University was relatively large, otherwise the children in the family area would have been scared.

The next day, the students were given a day off. Liu Hua and Professor Li each contributed another 105 yuan, making a total of 210 yuan, which was evenly distributed among everyone, 10 yuan each.

"Go play, eat and drink. Just enjoy yourself today."

Nowadays, ten dollars is a huge sum of money. You may not be able to spend all of it on food, drinks, and entertainment in a day.

Liu Hua and Professor Li took their results directly to the Science Department. They called their superiors overnight. The Science Department and the Driver Department organized people to review their chips today.

The audit was very serious and everyone was a little excited. They were both afraid and happy. The reason they were happy was that the super-large-scale infrastructure was successful, which marked that our country had caught up with the world's advanced level.

What we are afraid of is that if this news is a mistake or fails to pass the review, not only will everyone’s enthusiasm be wasted, but it will also easily cause many negative effects.

Liu Hua and Professor Li confidently handed over the information and chip samples to the experts for testing.

Some people took the chips into the laboratory for physical testing, and some experts began to look through the documents. For a moment, the conference room was very quiet.

Liu Hua and Professor Li sipped tea and occasionally exchanged a few words with each other. After waiting for about an hour and a half, the person in charge of the test came back.

Everyone in the conference room stared at him, and he nodded vigorously: "Yes, VLSI, and it is running well."

Warm applause immediately broke out in the conference room, and the two leading leaders stood up and shook hands firmly with Liu Hua and Professor Li.

“On behalf of the organization and the country, I congratulate you on this great achievement.”

Three minutes later, the leader said to everyone in the information: "Let's end the first part here. Next, let's get back to the topic and listen to Professor Liu and Professor Li's lectures. We must study hard."
