Chapter 323: Master, let's toss the precision

"Gu Song went to Huhai?"

Tian Deyu nodded: "It was said that it was the preliminary work of dealing with tape-out and processes in the past." 6 8 6 8 6 read 6 books, .□.≠o I'm worried about what conditions Huhai put forward in private. ”

Liu Liangmu pondered for a while: "I can't avoid it." The foundation of Wuhu is indeed worse than others, but Xinhuo Technology has decided to settle in Wuhu, and we will do the work that should be done. First of all, arrange the procedures for the planned land as soon as possible, and do a good job in the infrastructure work. Deyu, tomorrow his assistant and Mr. Liao, who is responsible for the preparation, will come over together, this trip to investigate, related to when the design and planning of the factory can come out, I want to trouble you to coordinate the units. ”

"I'll keep an eye on it. ”

Liu Liangmu said: "For the time being, you will take charge of the planning of the optoelectronic industry belt and serve the implementation of Xinhuo Technology as soon as possible." In the scientific research of related topics, it is necessary to organize scientific research institutes in Wuhu to study whether they can participate as much as possible. This matter is related to the centennial development of Zhonghu, and there are heavier burdens to be handed over to you in the next stage. ”

Tian Deyu's heart moved, and he said calmly: "I must be conscientious in this matter and live up to the trust of the province." ”

Liu Liangmu paused for a moment and asked, "Did Gu Song mention when he would return to Zhonghu?"

"It is said that after the Huhai trip, I will go back to Yanjing, and I will return to Yongning after attending the company's annual meeting. The time is estimated to be around the 20th. ”

"It's only half a month...... Liu Liangmu frowned and said, "Can the foundation of Xinhuo Technology be laid in time for this time?"

"Procedures for the registration of companies, procedures for land auctions...... I'll organize it. Tian Deyu touched it and nodded.

"Well, take this opportunity to report the preliminary planning ideas of the optoelectronic industry belt to the leaders. Wang Bang attaches great importance to this project, not to mention that it can be put into production this year, within this year, Xinhuo Technology needs to be built. Strive for this time next year, the optoelectronic industry with a new look. ∔ Eight ∔ Eight ∔ Read ∔ Book, .↗.â–Čo"

Tian Deyu smiled and said, "Then Yongning's side also needs to work harder." ”

Liu Liangmu also smiled: "It depends on the ability of the Yongning team." Gu Song is from his hometown, and he has a lot of plans in Zhonghu. Some of them can land first, so you can start thinking about it. ”

"I'll talk to them when I get back. ”





Zhonghu is worried that Huhai has other means to win over Gu Song, and Gu Song has actually been soaking in Huhai Microelectronics Equipment and Huaxin International.

Regarding the technical problems of immersion lithography, Gu Song naturally has a full set of solutions in his mind.

Whether it is the type of wetting liquid, or the immersion method, bubble elimination, and pollution deposition, there are ways to solve it.

But the problem is the control of large numerical aperture projection objectives and polarized light.

These two problems involve the most expensive and complex parts of the entire lithography machine.

Dozens of lenses of various specifications, each piece has to be polished with high-purity translucent materials for high-quality polishing, the surface of the lens is slightly curvature is wrong, or the impurities in the lens are diffracted and refracted incorrectly, and the image defects after refocusing will be magnified exponentially.

Not to mention the lens material and processing accuracy, this thing, using the traditional way, no matter how the number of lenses is stacked and matched, it is difficult to achieve the aperture required for immersion lithography.

But with a catadioptric projection objective, it's much more complicated.

Gu Song can give the drawings, but the problem is that he can't make them now. The grinding of lenses, the processing of other parts, and the precision of assembly are not up to that level.

The difficulty with this thing is precision. Someone once used an analogy to say that it is equivalent to two large planes from take-off to landing, always going hand in hand. A knife stretched out from one plane and carved words on the rice grains of the other, so that it could not be carved.

The real situation is even more exaggerated than this, this is a nano-scale operation, the scale of one-thousandth of a hair.

Lenses that achieve this level of precision are all hand-polished. The surface of a mirror is divided into tens of thousands of dots, each with an error in the ten-digit nanometer.

Absolute Holy Hand!

Asmail is not a panacea, he also buys the best parts everywhere and finally integrates them. But the problem is that he can't get the best parts.

I have a complete book of black technology in my head, but I can't process this thing directly.

On the contrary, the control of polarized light is relatively simple, although it is also very precise design and processing.

"Mr. Niu, if I can give a full set of design drawings and process plans, are you sure about lens processing and assembly?"

Niu Junming confirmed: "A full set of design drawings and process plans?"

Gu Song didn't care about his reaction, he just nodded affirmatively.

Niu Junming's face changed, and finally gritted his teeth and said: "This can only be piled up by manpower, relying on the number to fight." ”

This is also a fact, and Gu Song can't be demanding: "Okay, this is a special topic." As long as this hurdle is passed, the projection objective lens and liquid supply device required for immersion lithography will break through. ”

If it really doesn't work, let's see if we can refine the problem and extort some craftsmanship skills from my wife.

Zhang Rujing felt that his feet were very soft: "Do you have to move the projection objective? If this thing is broken, it is equivalent to the waste of the whole machine." ”

Gu Song sighed: "No wonder it burns money to develop this thing, 1.5 billion is too little, and a lithography machine can't burn it out." ”

If 1.5 billion can burn a lithography machine, a lot of people will lose their money to burn it. Zhang Rujing rolled his eyes and tried to make a final effort, "Can't you do the 250nm process first?"

"It's simple, and the high-tech process has to be broken through. ”

"That simple ......" Zhang Rujing was angry, "You can do it first, and I can cooperate with you at any time." ”

"Haven't I come yet? When Aoyama came from Wuhu, he began to tackle the 250-nanometer tape-out. ”

"You've got your design done?"

Gu Song looked at him strangely: "The specifications of this tape-out have been set, and of course the design has been done." ”

Zhang Rujing inhaled a cool breath: "You are really not a person in this laboratory, isn't it the theory of optical process that has been figured out? Even the memory chip of the 240nm process has been designed, and how large is the design capacity?"

"This simple point of tape-out, 8 layers of memory unit, 4 layers of packaging, and a single 4G capacity. ”

"4G ......" Zhang Rujing muttered, this is the capacity made under the 250nm process.

What about 180 nanometers? What about 130 nanometers? A single piece must not have a capacity of 32g?

The top flash memory that is now mass-produced only produces 1G per year, isn't it?

The low-level flash memory used by the USB flash drive, the mainstream talent!

What a sea change!

All of a sudden, his heart itched: "When will Liao Qingshan arrive?"

"The day after tomorrow," Gu Song ignored his reaction, and continued to discuss with Niu Junming: "What are the parameters of the lenses with the best accuracy that can be bought now?

Niu Junming was speechless for a long time, and finally said a little complainingly: "You still report to the top to see if you can transfer a few national players to participate in the project." ”

Zhang Rujing and Niu Junming's mood is the same.

I'm angry, but I still have to play with him!11 Baidu take a look at the latest chapter of "The Life of Rebirth as a Champion of Literature" to read for free for the first time.
