You say you have an iron will, are you serious?

Chapter 58 Semiconductor Etching
People from Zhongwei Company have been waiting for a long time.

However, everyone at Zhongwei Company was relieved when they saw Vice President Chen from PBC University leading the team in and expressing their apologies enthusiastically.

Then, the two parties began cooperation negotiations.

In response to this, the two sides will naturally go back and forth to gain more benefits for themselves.

Business behavior can be mixed with a little emotion, but it cannot be influenced by emotion. Just do what you want, so that you can have long-term cooperation.Otherwise, you will use emotions to talk about things. In the end, 99% of the time, interests will collapse, and then emotions will collapse, and in the end there will be nothing to talk about.

However, in the semiconductor field, there are still some differences.

"...When I came back to China, I was warmly invited by Director Jiang from Shanghai, who is also my junior; the second one is that I want to do something for the national semiconductor industry. The current situation is that we need people and no one, and we need money. I have no money and my business is about to fall into trouble. I will go abroad next month to attract investment..."

During the negotiation, Lin Zhiyao suddenly talked about his experience with emotion, and then said: "So, in terms of price, we may not be able to sell too much. I hope you can understand this~"

"Understood, we understand~"

Regardless of whether it was Vice Principal Chen or Deputy Director Zhou, they all responded quickly.

Zhao Mo also expressed his understanding.

Good guy, you are too embarrassed to refute this emotional card.

A rebuttal, no matter whether it is a success or a failure, no matter what your true thoughts are, it means that you are obstructing the progress of the national semiconductor industry.

People in this era are still somewhat spiritual, and are still very simple in their emotions of "dedicating themselves to the country." They are in awe when it comes to "dedicating themselves to the country" and are willing to do it themselves.Unlike later, when the Internet became so chaotic that people started to sneer at the rhetoric of "patriotism" and "dedication". A large number of people commented on such videos like "Who loves me?" and "It affects my salary of 3000 a month." "?" and the like, even to the point where one has to be cautious when expressing "patriotism", which is simply ridiculous.

Therefore, when Lin Zhiyao mentioned this, Zhao Mo later expressed that he could give in.

As the person involved, Zhao Mo suddenly asked a question out of curiosity: "Professor Lin, you have worked in the semiconductor industry for many years. Could you please explain to us some aspects of semiconductors, such as the development history and manufacturing process flow?"

Lin Zhiyao smiled and asked: "Is Zhao Mo very interested in the semiconductor field?"

Zhao Mo smiled and nodded: "Yes, I am very interested. A small thing as big as a fingernail can integrate hundreds of millions of transistors. It is really the ceiling of human industrial manufacturing. I think the semiconductor field will be The core area of ​​future great power competition.”

Lin Zhiyao was shocked, not only shocked by Zhao Mo's eyes, because he himself also held such a view, but also shocked by the fact that there seemed to be something in Zhao Mo's words.

"Maybe I'm overthinking~"

Lin Zhiyao shook his head, discarded this strange idea, and instead extended an invitation to Zhao Mo with a smile on his face: "Are you interested in working at Zhongwei Company? With Zhao Mo's talents in mathematics and computers, I believe you will definitely It can bring great help to Zhongwei Company."

Feeling that Vice President Chen, Deputy Director Zhou, Professor Yao and others were looking at him, Zhao Mo suddenly felt uncomfortable and said quickly: "No, I only know a little bit, so I can't be of much help. of."

Lin Zhiyao smiled and nodded, not taking his words seriously, but thinking that he was just being modest.

Later, Lin Zhiyao briefly explained the development history of the semiconductor field and the main work of Zhongwei Company: "...I mainly work in several companies such as Fanlin, Applied Materials, and Tokyo Electronics abroad, researching semiconductor etching equipment. Therefore, the current research work of Zhongwei Company is to localize the etching equipment, which requires a very heavy workload..."

Zhao Mo listened very carefully.

Etching, as the name suggests, uses etching to engrave circuit patterns on the wafer.

Although etching equipment is not as difficult to manufacture as photolithography machines, it is still one of the most difficult equipment to manufacture in the field of semiconductor manufacturing, especially high-level etching equipment. Currently, there are only Fanlin, Applied Materials, and Tokyo Electronics can do these three companies.

Lin Zhiyao has worked in all three etching equipment manufacturing companies, and he is the core figure and leader of the team. He is the biggest contributor to the success of their etching equipment and their move to high-end!
"Current etching technology can be divided into wet etching and dry etching according to process division."

"Wet etching includes chemical etching and electrolytic etching. It uses liquid reagents, so it is low cost, simple to operate, and has a wide range of applications. However, this method is prone to slopes on the sides and requires rinsing or drying. The steps are not suitable for increasingly advanced manufacturing processes.”

"Dry etching is different. Its cost is very high and the selected materials have poor etching properties. However, it does not have the disadvantages of wet etching. It is usually etched with ion beams, high-density plasma, reactive ions, etc. , the etched side is anisotropic, has the advantage of less photoresist shedding, and a high etching rate, so dry etching has advantages in fine etching of small feature sizes in today’s advanced processes.”

……

What was supposed to be a fierce negotiation suddenly turned into a technical exchange meeting.

After he finished explaining, Lin Zhiyao realized that he seemed to have talked too much and couldn't help laughing and shaking his head.

Fortunately, Vice Principal Chen, Deputy Director Zhou, Zhao Mo and others were all listening attentively. Everyone seemed to have gained a lot, and Lin Zhiyao was secretly relieved.

"So, although the problem of reactive ion sources has been solved, it is actually only the first step in a long journey for the manufacture of domestic etching equipment. And reactive ion etching still needs further improvement?"

Zhao Mo suddenly said thoughtfully.

Lin Zhiyao nodded and said, "That's right."

"It's so complicated!" Zhao Mo was secretly shocked.

It is said that semiconductors are the crystallization of human modern industrial civilization. He has never had any idea. Like most Chinese, his attention is focused on photolithography machines.Now he knows that it is indeed a crystal. Etching equipment that has almost no presence in the field of semiconductor manufacturing is so complicated, let alone a photolithography machine.

At the same time, he also knew that various scientific principles did represent modern human civilization, but actual industrial manufacturing also represented modern human civilization, and no one was superior to the other.

Being able to use these principles to build a variety of machines and equipment to serve modern civilization and continuously create wealth for mankind is even more important to a certain extent!

"It's not easy~"

Vice President Chen lamented that he was an administrative principal, not an academic, so it was the first time he had heard of these detailed technical issues.

Then, he curiously asked: "How big is the gap between our country and foreign countries in this field?"

Lin Zhiyao replied without hesitation: "Two or 30 years. If we catch up now, I believe we can narrow the gap to less than ten years."

"..."

Vice Principal Chen was extremely shocked and then continued the topic.

It is better not to talk about unpleasant topics for a long time.

Zhao Mo has no worries. He knows that this gap is indeed very large and will not change even in the next ten years.However, for a red country with a national system that can concentrate its efforts on big things, these can all be solved, because semiconductor manufacturing is gradually approaching its limit, which gives us the possibility to catch up.

"There is still a lot of potential in the field of semiconductor manufacturing equipment."

Zhao Mo smiled and said, "Professor Lin, I believe the current difficulties are only temporary. The road is tortuous, but the future is bright."

"I believe too."

Lin Zhiyao looked at him deeply and said, but in fact, he was still a little uneasy about whether Zhongwei could succeed.

He did not expect that here at Wudaokou, the 17-year-old boy who helped them solve the problem of the reactive ion source seemed to be more confident than him.

Then, he recalled that after meeting Zhao Mo, Zhao Mo's reaction seemed to be very determined and full of confidence.

He didn't know where Zhao Mo's confidence came from, but he admired it and thought to himself, "Maybe this is what makes geniuses unique."

Think about it when he was 17 years old, even though he was considered a genius by others, his performance was still inferior to Zhao Mo's.

While waiting for the negotiation, he saw two papers published by Zhao Mo in "Chronicle of Mathematics".He had to admit that Zhao Mo was indeed amazingly talented.There were some parts of these two papers that he didn't understand, and he only vaguely understood part of them after pondering for a long time.Perhaps it was because of his old age, but he knew that it was largely due to the difficulty level of these two papers.

"Professor Lin, we accept your company's conditions for this plan. The technology will be developed first."

After thinking about it, Zhao Mo and Gu Rong discussed it and then made a decision.

Even if it is a small contribution to the national semiconductor industry.

Lin Zhiyao was stunned.

Vice President Chen, Zhou Zuojian, Professor Yao and others were all stunned.

Du Xiao from Zhongwei Company was also stunned.

They didn't expect that Zhao Mo would make the decision so readily.

"Thank you! Classmate Zhao Mo, the door of Zhongwei Company is always open to you, and you are welcome to come to Zhongwei Company as a guest~"

Lin Zhiyao's mood even became a little excited. He stood up and reached out his hands to Zhao Mo enthusiastically.

Zhao Mo quickly stood up, stretched out his hands, and then said with a smile: "You're welcome, didn't you pay 10 yuan in advance~"

Click!Kacha~
Someone from Zhongwei Company filmed this scene.

After the matter was negotiated, Lin Zhiyao and others wanted to invite Zhao Mo and others to dinner, but Vice President Chen said that there were still media interviews to deal with, so the two parties quickly dispersed.

"What's it like to be interviewed?"

After leaving the conference room, Zhao Mo entered the interview place with nervousness and anticipation under the arrangements of the staff.There, people from CCTV have been waiting for a long time.
