1991 Starting from the core

At noon, after a simple meal, the meeting continued.

When discussing the control system, Li Mingliu and others from Yuanxin also joined in. Then it was over. What was originally a discussion about statistical requirements was turned into a purely technical discussion.

During this period, Zheng Zhenchuan wanted to remind these people not to go off topic, but he gave up when he saw that Su Yuanshan was listening with gusto and even picked up his notebook to keep writing.

Just when the engineer from Chengguang Institute was about to get the drawings for the second time, Su Yuanshan raised his wrist and looked at the time.

"Ahem... Why don't you stop for a moment?" Su Yuanshan raised his notebook and smiled: "Teachers, brothers and sisters, I have roughly written down that in order to achieve the ideal alignment system solution, in addition to micromotors, It seems that many types of optical diodes are needed, right? In addition, I heard from Lao Liu that the PCB of the control circuit needs to be redesigned."

"Of course, I don't understand lithography machines, but I know from technical intuition that lithography machines will definitely be the key to restricting the chip manufacturing process in the future - we are EDA developers, and we know that the upper limit of the process that Yuanxin EDA can design is far beyond the current Based on this, we must adopt new technologies if we can, and use new circuits if we can. After all, circuit boards are constantly maturing through trial and error."

"Especially for precision instruments like photolithography machines, just heat dissipation and anti-interference require long-term verification. Don't you think so, Mr. Zheng?" Su Yuanshan asked Zheng Zhenchuan with a smile.

Zheng Zhenchuan smiled meaningfully and nodded: "That's right. Lao Zhou, you and Master Li should stop arguing."

Lao Zhou is an old engineer about forty years old and has been responsible for various circuit designs of the alignment system here. Frankly speaking, he had some complaints about Zheng Zhenchuan calling a private company like Yuanxin to come over to help... and he almost completely denied his previous work when he came over, which was really hard for him to accept. So in the past two months, he and Li Mingliu's team have been working together, striving to innovate and iterate based on the original circuit design.

It's just that he didn't expect that Li Mingliu would bring up the old talk again after the little boss came today. How could he bear this?

Lao Zhou snorted softly: "Director Zheng, this is not an indisputable issue. The thickness of the circuit board will affect the overall accuracy of a precision instrument such as a lithography machine. How can it be possible to rebuild it all? It would be better to start over the entire machine. Start designing.”

"It's okay." Li Mingliu argued: "Zhu Jianting has been working on the mechanical CAD for half a year. The test version will be available in the second half of the year at the latest. Then we can just take it and draw it again - Chen Gong, your design team There is no need to use a magnifying glass to look at the drawings every day.”

The middle-aged man named Chen Gong coughed.

Su Yuanshan didn't know whether to laugh or cry, and he covered his mouth and coughed.

He knew that even in T University, this guy Li Mingliu was the kind of arrogant person. After entering Yuanxin, he and Xi Xiaoding finally surrendered, but that didn't mean that he really lost his arrogance - others would probably be intimidated when they heard about the Institute of Optics of the Chinese Academy of Sciences, but that depends on the field.

Let’s not talk about the mechanical and optical parts, that is their domain, and they should be awesome. But the IC and circuit parts are Li Mingliu's field, and Li Mingliu has participated in the entire development of EDA simulation tools. In this area, he is a well-deserved expert.

Seeing Su Yuanshan's reminder, Li Mingliu also knew that what he said was a bit sharp, and immediately said seriously: "Old Zhou, really, listen to me. If you are worried about the size, we can leave some space, but the thing before was really not good - — Yuanxin's VCD board was designed by me, and it was reduced from the size of a dinner plate to the size of a dictionary. You think I'm awesome? Damn! That's a lie to a layman!"

His last words made Lao Zhou's face look a little better.

"Our design relies entirely on EDA simulation. Tell me, how do you simulate the board you designed? Can it keep up with Yuanxin's simulation tools?"

Lao Zhou opened his mouth and began to sulk after realizing that he couldn't refute.

Su Yuanshan looked at Zheng Zhenchuan and saw Zheng Zhenchuan smiling like a normal person: "It's okay, it's all for work, just get used to the noise. Don't look at Mr. Chen drinking tea over there. When he was just designing the drawings, he was noisier than anyone else. Loud.”

Zheng Zhenchuan straightened his expression as he spoke: "Okay, while Mr. Su is here today, we will make a final decision. All circuits will be redesigned."

The person responsible for statistical demand immediately asked: "Will the components change? Do I need to purchase additional new ones?"

"Design it first and then talk about it. Today you sort out what we urgently need at this stage."

Zheng Zhenchuan waved his hand and concluded today's meeting.

Su Yuanshan declined Zheng Zhenchuan's offer to stay and see him off, and only asked Li Mingliu and others to see him off to the parking lot. Shen Haoran here has decided to join Yuanxin, so they are all his own people.

"Mr. Shan, have you seen it?" Li Mingliu said with a wry smile: "When I was a child, I thought the Academy of Sciences was so mysterious and great, but only after getting closer did I realize... Alas!"

Shen Haoran smiled and walked down the steps for the lithography machine department: "The electronic tube technology that the military industry department has been using before is mature and reliable after all. Although it is now making great strides to pursue the semiconductor industry, the demand for lithography machines is mainly for civilian equipment. , so I don’t invest that much, and I’m used to being in charge of things.”

"You want to change just because you are poor! You can't say that you have gone through all kinds of difficulties under difficult conditions to create an awesome abacus that can calculate a hundred times per second, and then just leave it to the calculations of 10,000 times per second. If you don’t use it, say it’s your hard work! What a waste of development.”

This metaphor made Su Yuanshan smile.

"Okay, stop complaining. Help them get this lithography machine up and running better, and they will have more funds for the next one."

Li Mingliu pursed his lips: "How much more can we get? I heard that Nikon and Canon's annual research and development costs are hundreds of millions, or US dollars."

"Haha, take your time, you have to have an understanding. As long as the lithography machine they are researching can achieve yield at a certain line width, then there will definitely be a market - if they can't make high-end ones, why can't they make low-end ones? ?With the development of the semiconductor industry in the future, it will also drive a large number of electronic and electrical equipment. By then, various low-end ICs will definitely be in short supply."

"This is the lowest level of the reason why we help Chengguang Institute."

After getting in the car and waving goodbye to everyone, Su Yuanshan asked Zhou Xiaohui to take a look at his needs.

This list will shock you if you don’t know it.

Chengguang Institute is really poor. In addition to high-precision components such as motors, capacitors and inductors that must be imported, Su Yuanshan even needs help in purchasing chip diodes.

"Are we talking about money today?" Su Yuanshan turned to look at Zhou Xiaohui.

Zhou Xiaohui pursed her lips, smiled and shook her head.

Su Yuanshan chuckled: "Let them remember all the pens and don't miss a diode. When the time comes, we will bring the machine back if they dare not pay."
