Rebirth: Fight For Life

   Chapter 324 Master, let's toss the precision

   "Gu Song went to Shanghai?"

  Tian Deyu nodded: "It's said to be the preliminary work of handling tape-out and craftsmanship in the past. I'm worried about what conditions Huhai put forward in private."

Liu Liangmu pondered for a while: "It can't be avoided. 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, arrange the procedures as soon as possible in the planned place, and put the infrastructure The work is done. Deyu, his assistant will come over tomorrow with Mr. Liao, who is in charge of the preparatory work. This visit will depend on when the design plan of the factory area will come out. Please coordinate the various units. "

   "I'll keep an eye on it."

Liu Liangmu said: "For the time being, you will be doing this job first. You are in charge of the planning of the optoelectronic industry belt, and you can serve the implementation of Xinhuo Technology as soon as possible. For the scientific research of related topics, you should also organize research institutes in Wuhu to study, can you try your best? Participate more. This matter is related to the century-old development of Zhonghu, and there is still a heavier burden to be entrusted to you in the next stage."

  Tian Deyu moved in his heart and said calmly, "I will do my best in this matter and live up to the heavy trust of the province."

  Liu Liangmu stopped for a while and asked, "Did Gu Song mention that when he will return to Zhonghu?"

   "It is said that after the Shanghai trip is over, I will return 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 in time for this time?"

   "The procedure of company registration, the procedure of land auction...I'll organize it." Tian Deyu made a guess and nodded.

"Okay, take this opportunity to report the preliminary planning ideas of the optoelectronic industry belt to the leaders. Elder Wang Bang attaches great importance to this project. If it can be put into production this year, Core Fire Technology needs to be built within this year. The optoelectronics industry has a new face."

   Tian Deyu smiled and said, "Then Yongning 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 can be implemented first, so you can start thinking about it."

   "I'll talk to them later."

  …

  Zhonghu was worried that Huhai would have other ways to win over Gu Song, but Gu Song had actually been soaking in Huhai Microelectronics Equipment and Huaxin International.

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

   No matter the type of infiltration liquid, the immersion method, the elimination of air bubbles, or the deposition of pollution, there are ways to solve it.

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

   These two issues involve the most expensive and complex components in the entire lithography machine.

Dozens of lenses of various specifications, each of which must be polished with high-purity light-transmitting materials, the surface of the lens is slightly incorrectly curved, or the impurities in the lens are diffracted and refracted incorrectly, and the image defects after refocusing will be Multiply magnification.

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

   But catadioptric projection objectives are more complicated.

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

  This thing, the difficulty lies in the accuracy. Someone once used an analogy to say that it is equivalent to two large planes that always go hand in hand from takeoff to landing. A knife sticks out from one plane, and engraves words on the rice grains of another plane. It cannot be broken.

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

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

   Absolute Master!

  Asmail is not omnipotent, he also buys the best parts everywhere and finally integrates them. But the problem is, he can't buy these best parts.

   There is a whole book of black technology in my mind, but this thing can't be processed 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 complete set of design drawings and process plans, are you sure about the processing and assembly of the lens?"

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

  Gu Song ignored his reaction, just nodded affirmatively.

  Niu Junming's face changed, and finally he gritted his teeth and said: "This can only be done by manpower, and it depends on the number."

   This is also true, and Gu Song has no way to be demanding: "Okay, this is a special topic. As long as this hurdle is over, the projection objective lens and liquid supply device required for immersion lithography will be broken through."

   If it doesn't work, it depends on whether you can refine the problem and extort some craftsmanship from the wife.

   Zhang Rujing felt that his feet were very soft: "Do I have to move the projection objective lens? If this thing is broken, it is equivalent to the whole machine being useless."

  Gu Song sighed: "No wonder the research and development of this thing burns money, 1.5 billion is too little, and a lithography machine can't burn it."

"You are so beautiful! If 1.5 billion can burn a lithography machine, a lot of people will lose money and burn it." Zhang Rujing rolled his eyes, trying to make a last effort, "You can't start a 250-nanometer process first. ?"

   "That simple, high process has to break through."

   "That's simple..." Zhang Rujing was in a hurry, "You have to do it first, I can cooperate with you at any time."

   "I'm not here yet? When Qingshan comes over from Wuhu, we will start to tackle the 250-nanometer tape-out."

   "Did you design it?"

  Gu Song looked at him strangely: "The tape-out specification is set, and of course the design is ready."

   Zhang Rujing sucked in a breath of cold air: "You really aren't people in this lab, haven't you figured out the theory of optical technology? Even the memory chips of the 240nm process have been designed? How big is the design capacity?"

   "This tape-out is simple, with 8 layers of storage units, 4 layers of packaging, and a single 4G capacity."

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

What about   180nm? What about 130nm? A single capacity must not be 32G?

   The top-level flash memory in mass production is only 512M. Will it be able to produce 1G in 2003?

   The low-level flash memory used in U disk, the mainstream is only 64M, 128M!

   This is an earth-shaking change!

   For a while, his heart was itching: "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 lens with the best accuracy that we can buy now? If our master polishes it further, to what level can the accuracy be improved?"

  Niu Junming was speechless for a long time, and finally said a little complaining: "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 have the same mood.

  I'm so angry, but I have to play with him!
