Su Xinghe and Zhang Ke laughed. Both of them were used to treating Su Yuanshan as an old adult. At this time, they rarely showed excitement when they saw Su Yuanshan, and they all felt like they were their son and nephew.

My uncle raised his voice, like an old cadre who was mixed with me: "Young man, don't be so anxious, it's the New Year."

"Your uncle is right, what about the New Year." Su Xinghe looked at his son and smiled: "I'll wait for the New Year to talk about it - and you can watch it, there's no news on TV now."

Su Yuanshan smiled and shook his head to sit down. He also knew that he was too excited just now. But there was a reason why he was excited, because he knew that the spring breeze would blow, and he would say, "Be bolder and take faster." Since he had this foresight, it would be unreasonable to not do anything.

At this time, the knock on the door sounded. After opening the door, Professor Li Gaoliang was holding two bottles of wine in his hand, and a middle-aged man of about the same age stood behind him.

This attitude made Su Yuanshan very stunned - Li Gaoliang lived upstairs and was not uncommon to visit him, but it was rare for him to bring two bottles of wine to come. He was the head of his father!

"What? Xiao Su, don't let Uncle Li enter the door?" Li Gaoliang saw Su Yuanshan a little confused and joked.

"No, Uncle Li, what does this wine mean? My house is not a sales store." Su Yuanshan quickly opened the door and turned around and shouted: "Dad, Uncle Li is here."

Su Xinghe had heard the sound for a long time, walked quickly to the door, and greeted the two of them in with a haha.

...

After introducing his identity and greetings, Su Yuanshan moved a stool and sat next to his uncle, with an uncontrollable smile on his face - it was not polite, but a real smile.

Zheng Zhenchuan, deputy leader of the Optoelectronics Project Team of the Institute of Optoelectronics Technology of the Chinese Academy of Sciences, is also a classmate of Li Gaoliang.

The wine was naturally brought up by Zheng Zhenchuan.

My aunt came out of the kitchen, soaked tea for the guests, and then took the girl into the kitchen, leaving the living room for the men.

"Old Su, we are not polite. My old classmate is facing some difficulties in the project under his command. Look at how Yuanxin can help me." Li Gaoliang touched his head and said to Su Xinghe, and finally looked at Su Yuanshan again.

He knew that Yuanxin was actually Su Yuanshan, the genius who was responsible.

Su Xinghe smiled and nodded: "Well, Master Zheng, please say."

"Okay, our optical and mechanical institute has been doing the imitation and development of lithography machines. The problem now is that we are all fine in the light source part and other hardware, but the embedded system is very difficult." Zheng Zhenchuan has been in the provincial capital for many years, and has learned a Sichuan sound, shook his head, and said with a wry smile: "Now, looking at the country, Professor Su's Yuanxin has the ability to develop an embedded system suitable for lithography machines, so I'm here to worship the Bodhisattva."

"Haha, what's Zheng Gong talking about?" Su Xinghe laughed at him and praised him. He turned to look at his son: "Xiaoshan, can you still draw a team there?"

Su Yuanshan pursed his lips and smiled very much.

"Since Uncle Zheng has spoken, we have to help even if we stop EDA!"

Everyone laughed loudly. Zheng Zhenchuan looked back at his old classmate. After seeing Li Gaoliang nodding with confidence, he immediately breathed a sigh of relief. When he was at home, Li Gaoliang told himself that Yuanxin Company was actually responsible for Su Xinghe's son, and this child was a truly famous genius in Silicon Valley.

Next, Su Yuanshan simply asked Zheng Zhenchuan several questions about lithography machines, which made Zheng Zhenchuan look at him with admiration.

After arguing that after the New Year, Li Gaoliang and Zheng Zhenchuan stood up and said goodbye, but refused to stay for dinner.

Close the door, Su Yuanshan slapped the high-high again with excitement.

"Dad, do you know what it means to give someone a pillow if you want to sleep? That's called!"

Su Yuanshan said and laughed, jumping into the sofa.

Domestic lithography machines, or optical precision machinery, actually started not late. As early as the 1950s, the Changchun Institute of Optical Machinery of the Chinese Academy of Sciences was established. Then in the 1960s and 1970s, the Changguang Institute assisted in the construction of Xiguang Institute, Shangguang Institute and Chengguang Institute in Xijing, SH, and provincial capitals respectively.

Since they are blooming everywhere, their respective focus will naturally be different. As the grandfather’s generation, the Changguang Institute dominated the overall situation, and the Xiguang Institute mainly studied space optics, optoelectronic engineering and other fields; the Shangguang Institute mainly focused on strong lasers, information optics, photonic materials and other fields; and the Chengguang Institute, which is the provincial capital optical machinery institute, proposed as early as the 1970s that the main direction of the future is optical measurement equipment and large-scale integrated circuit equipment research projects. (Skip the Anguang Institute here)

But Su Yuanshan knew that these research directions of Chengguang Institute had failed.

It is now early 1992. Next year, Chengguang Institute will launch the first g-line lithography machine known as one of the top ten electronic scientific and technological achievements - a 1.5-2 micron step-by-step repeated projection lithography machine. However, because the yield is too low, it can only be used as a prototype...

Later, Chengguang Institute continued its efforts and developed a distributed projection lithography machine of 0.8-1 micron, and claimed to be the only lithography machine that has produced components independently developed.

Listen to this wording, "made" components - there is stubbornness in the sadness.

From then on, domestic lithography machines have been around for a hundred years.

As a practitioner in related industries, Su Yuanshan has certainly learned about the history of domestic lithography machines. In fact, the 2-micron lithography machine built by Cheng Guang is a 2-micron lithography machine that imitates NEC, but the hardware can be counterfeit, so there is no way to embedded systems. Especially for various fine-tuning, it requires the dual support of systems and experience.

Su Yuanshan’s plan this year is to take advantage of his own provincial capital to help the people from Chengguang Institute gain experience. Before he could figure out how to make excuses to cooperate, he came to the door. Isn’t this to sleep? What’s the point of someone giving me a pillow?

...

Seeing Su Yuanshan excited, his father calmed down: "Don't be too happy too early. There are tens of thousands of parts in the lithography machine, which are extremely precise instruments. To develop an embedded system, you must have a certain understanding of its system and structure. Do we have such people?"

"Of course we don't, but we can learn from each other." Su Yuanshan smiled: "And lithography machines are complicated to say, but in fact, the most difficult thing about embedded systems is to solve the alignment system. To put it more details, the cooperation between stepper motors, torque motors, servo motors and other motors..."

Speaking of this, Su Yuanshan suddenly stopped.

Zhang Ke, who was listening with relish, was stunned: "Why don't you say it?"

Su Yuanshan sighed softly: "Because these motors seem to be non-domestic."

In fact, the domestic laser light source part has not been much behind, and it is even ahead of its application in some fields. However, high-precision machinery such as lithography machines, which combines various top technologies, is the most affected by the barrel effect.

"Just import it, at worst, the cost is higher." My uncle said disinterestedly.

Su Yuanshan smiled and squinted his eyes and looked out the window. It was a cold winter outside.
