After breakfast the next day.

"Brother Shan, I have two friends coming over. ”

"Friends?"

"Well, two big beauties!"

"Big beauty, are you beautiful?"

"It's not much, but it's a foreign girl, a princess of a big family, and a top student!"

"More than you?"

"A little bit better than me, just a little bit!" Saying that, Ning Xin'er also pinched with her thumb and little finger.

"Really?" I asked with a smile.

"Really, that princess is not only beautiful, but her family is the second most beautiful in India, and she is a true nobleman; Another top student, who has a doctorate in physics and chemistry...... Anyway, I've already got several degrees, and I'm amazing!"

"How many degrees do you get in a year?"

"No, they are all two years higher than me, and they are considered senior sisters. ”

"And you're still friends?"

"Hey, hey, is the average princess of the human book eye-catching?" Ning Xin'er said proudly.

"And what are they doing here?"

"Of course it's to see my boyfriend!"

"What kind of god, didn't you tell me about me in Xiangjiang?"

Ning Xin'er stuck out her little tongue, "I accidentally said something out of my mouth once." ”

"Don't talk about this kind of thing in the future, and you can't talk about the things of these two days. ”

"What's going on these two days?" Saying that, Ning Xin'er glanced at Li Ping.

"Don't ask so much!"

"Oh!"

.......

A little after eight o'clock, with a knock on the door, two beautiful foreign chicks entered.

"This Indian beauty is called Agim Premji, I call her a hen, this one is a Dutch beauty, call her Anne!"

Ning Xin'er first mischievously introduced me to two beauties in Chinese.

"This is my boyfriend, Li Xiaoshan, handsome, right?" After Ning Xin'er finished the introduction, she came over and proudly took my arm.

It's really two big beauties.

Even if the Indian beauties among the two are dressed conservatively, the plump breasts, thin waist, fat buttocks, the "three bends" on the body and a pair of big eyes can't hide the sexy and charming, but with a noble temperament with all kinds of amorous feelings, the whole person has both the classical beauty of the Orientals and the unique romantic temperament of the Westerners.

And the Dutch beauties are not much, with long curly hair scattered around the waist like seaweed, eyes as deep blue and clear as the sea, tall and plump, and white skin.

However, the whole person is a little faint, and smiling and greeting can't suppress that indifference.

"I didn't lie to you, did I?"

"Indeed, I almost have you beautiful!"

"You can speak, but let's stop speaking Chinese, it's rude." ”

"Ahem! Anne is Dutch, so the Dutch AS-ML company should have heard of it, right?"

Indian beauties are beautiful, but I'm not very interested in them yet.

As I have more and more women, beautiful women, the attraction to me is just like that.

As for this Dutch beauty, it reminded me of AS-ML, which makes top-of-the-line lithography machines, so I asked casually.

Lithography machine is the core equipment of chip manufacturing, which is the biggest shortcoming in semiconductor equipment manufacturing in China, the lithography machine required by domestic wafer factories is completely dependent on imports, and it is one or two generations behind, and the most advanced lithography machine is not sold to you at all.

In the manufacture of high-end lithography machines, the leading leader is AS-ML.

"Li, what a coincidence of your question, last month AS-ML sent me an invitation to work in their company's laboratory, but I didn't go. ”

My heart moved, Anne is still in school now, and AS-ML is coming to rob people?

"Does Anne know anything about lithography machines?"

"Lee, you don't know yet, Anne is a doctor of physics, a doctor of chemistry...... Many of her papers have won awards. At this time, the Indian beauty Agim interjected.

"Does this physics and chemistry have anything to do with lithography machines?" I'm still confused, we really don't understand high-tech stuff.

"This is a big deal, manufacturing lithography machines, not only requires top-notch physics, chemistry and other aspects of knowledge and technology, but also ...... In short, the top lithography machine can be said to be the essence of hundreds of years of industrial technology in Western countries, and it can be manufactured, and it is not clear in a few words. ”

Listening to Agim's words, I took a breath of cool air in my heart. I knew it was difficult to make semiconductors, but I didn't know it was so difficult.

After stabilizing his mind, he said, "Does Miss Agim also have any involvement in lithography machines?"

"No, I studied software, but I talked to Anne a lot, and software is related to these technologies, so I know a little more. ”

"Then I would venture to ask, Miss Anne, if you were given all the necessary conditions, would you be able to build a lithography machine?"

"Li, are you joking, do you know what kind of conditions are needed to develop lithography machines?"

"Miss Anne may as well tell me!"

Although I was stunned for a while, I was not discouraged.

Two bombs and one satellite can be built, and aircraft carriers in later generations can also be built, and I don't believe that there is anything that exceeds these two difficulties.

"Huge capital, professional talents, and sophisticated technology are all indispensable. ”

"Technology is still last?"

"It can be said that the principle of the lithography machine is not difficult, but an advanced lithography machine can have tens of thousands of parts, and it is not easy to design and produce, and the most difficult thing is that each step in it requires the most advanced technology. ”

"There is no shortcut in the research and development process of the lithography machine, which is a high-precision opto-mechanical integrated equipment, and the accuracy can only be improved step by step. Without a micron foundation, it is impossible to build a 90-nanometer device, a level that did not fall from the sky, but was gradually accumulated by others step by step over decades. ”

"So you need high-end talents and long-term accumulation, and time means spending a lot of money?" I asked.

"Yes, otherwise we wouldn't have been able to produce the drawings when we got them. Anne replied firmly.

"If you have money, there are people, and since the drawings are not the most important thing, then my boyfriend can do it. At this time, Ning Xin'er interjected.

"It still didn't work. Anne said lightly.

"Why do you say that, Miss Anne?" I asked, puzzled.

"The lithography machine can be said to be the crystallization of Western wisdom or human wisdom for hundreds of years, and it is a combination of cutting-edge optics, materials science, and machinery. ”

"Among them, the top lens and light source are the core things, without the top lens and light source, without the ultimate mechanical precision, it is still in vain. Dutch beauty Anne spread her hands and said.

"So you mean, if you want to make a top-level lithography machine in Huaxia, it's impossible?" I continued.

"That's pretty much!"
