Siheyuan: Starting from a fitter

Chapter 134 Report ([-])

"Yes, science cannot tolerate carelessness, let alone messing around," Mr. Zhao agreed.

"Nowadays, many investments have no returns, and the quality of products is even more difficult to describe," said Zhao's father.

"However, we have no choice. Now that Xiao Li has made some tricks and they are practical, you must strongly support Xiao Li's work in the future," Mr. Zhao and his father said.

"I know, Dad."

Lying on the bed, Zhao Ting brought up the topic from last time.

"My mother and I brought up the idea of ​​having a child again, but I didn't dare to tell the truth. I just said that I couldn't have one, so they asked me to go to the hospital for a check-up."

"What do you think?" Li Guocheng kicked the ball back to Zhao Ting.

"Actually, since I caught Old K, my wish has been granted and I no longer resist having children." Zhao Ting actually became shy when she said this.

"What are you waiting for".

. . . . . . .

The next day, the three of them gathered in Li Huaide's office.

"What's Mr. Zhao's opinion?" Li Huaide asked casually.When Wu Liankui heard his question, his expression was a little nervous, obviously he couldn't cultivate well.

Li Guocheng did not hide it, "What the old man meant, the results are all from the laboratory."

Without using their senses, they obviously breathed a sigh of relief.

"You also know that I don't like to appear in public, and the next research work will be more arduous. I don't have time to attend various meetings, so unless there are special circumstances, I will help the two leaders."

All the honors now are of little significance. If they can be free from interference, there is no problem in giving them all the credit.Li Guocheng's current identity is a worker. If anyone knows that he has such great achievements, he will definitely be regarded as a representative of the working class. He cannot escape his identity as an advanced worker.

At that time, they will be arranged to tour the country to introduce their experiences.It is conceivable that in recent years, there is no need to stop.Li Guocheng did not want to enter politics. These experiences and reputation had no effect on him, but instead affected the speed of his research and development.

"Isn't this good!" Wu Liankui said sheepishly, his face still tender.

"It's really inappropriate," Li Huaide agreed.

"Without Director Li's overwhelming support and strong support, there would be no current laboratory." Li Guocheng's flattering skills have improved.

"Everywhere, it's all you who work hard," Li Huaide said with a blushing face and declined again and again.

"Since the establishment of the laboratory, Director Wu has always ensured that the laboratory materials are sufficient and has personally participated in research. It can be said that he is well-deserved." Li Guocheng continued to lie.

"The laboratory is all supported by you. Without you, there would be no current results. I know how much I weigh. I listen to you all. As long as I need to do it, I am obligated." Wu Liankui is very smart. No matter what, as an experimenter Office leader, he has all the credit, he might as well buy a good one.

"We all know that foreigners are now developing CNC machine tools. Whether it is machining accuracy or efficiency, they are far beyond us. We cannot stand still and need to catch up," Li Guocheng mentioned again.

Having worked in machining all his life, Li Huaide deeply agrees with this.

"Machine tools, as industrial master machines, determine the overall manufacturing capabilities of the country's industry. When faced with Western CNC machine tools, the technological gap between us and Western developed countries will become wider and wider, and the country's overall strength will also become wider and wider."

"Can we really develop CNC machine tools?" The more Wu Liankui understood the machine tool technology, the more powerless he felt.

"Don't worry, it will definitely work. With the Shuguang II model, the processing capacity problem has been solved. The only problem now is the computer, but it will definitely be available in the near future." Li Guocheng is very confident.

"That's great, don't worry, you can do research with peace of mind from now on. I will cover all the reception of the laboratory," Wu Liankui vowed.

After the general direction was determined, Li Guocheng leisurely returned to the No. [-] Assembly Laboratory.

"Everyone, please come here," Li Guocheng clapped his hands and greeted everyone.

"This week's work is to summarize, no other work will be arranged."

"Long live", Zhou Xiaojuan was the first to shout. Although the other two did not shout, they were already beaming with joy.

Li Guocheng smiled, waved his hand, and let them go about their work.

Where was Li Guocheng sitting, thinking about the next direction of work.

First, the current single crystal ingot is only 50mm, which is often referred to as 2 inches.In order not to fall behind in the future, we must continue to invest in research into larger-sized wafer rods.In the next three years, the size must be 4 inches or more.

Second, we are now in the Stone Age of chip design and manufacturing. This time span spans approximately 1958 to 1975 abroad and 1958 to 1985 domestically.He hopes to keep up with the pace of foreign countries. It would be better if he can surpass it and enter the computer-assisted era earlier.

Third, the oscilloscope is an essential tool for future circuit development and testing, and it must be designed earlier, which requires an AD chip.

Fourth, computers must be developed earlier.

1971年Intel推出全球首个4位中央处理器(CPU)芯片4004。它集成了2250只晶体管，采用10μm工艺，这已经是当时规模很大的芯片了。

In 1974, Intel launched the 8-bit CPU chip 8080, which was manufactured using a 6μm process and integrated more than 6000 transistors.

It's 1967, and there's still time.The increase in size of the single crystal rod is left to Wang Gong; the research on the photolithography machine is left to Yan Jiefang; the etching machine continues to be left to Zhou Xiaojuan; AD research can be left to Zhang Zhijing.

Of course, if there is no suitable person for the research on computer display screens, it will be left to Yan Jiefang.The process optimization of wafer preparation is handed over to everyone; the subsequent process optimization of circuit boards is handed over to Wang Dayong.

There are still not enough people!Li Guocheng decided to ask Dad Zhao for help.

Li Guocheng's next main research direction is computer CPU and DRAM random access memory. The CPU is going to refer to the ARM architecture and instruction set of later generations. ARM2 only used 30000 transistors at the time, and its performance was better than the 80286 that Intel later launched.

With the meticulous precision of Li Guocheng's mind, the design of this chip can be completed through multi-layer masks.The current photolithography accuracy is still 10 microns, and it must be 1 micron by then. Of course, this mainly tests the accuracy of the mask and the cooperation of the lens group.

After thinking about it, this seems not impossible.

Of course, if you want to create a low-power CPU, you must first design NMOS and PMOS. This principle has been taught in universities. Now Li Guocheng can only try it slowly based on memory.

After wanting to understand this, Li Guocheng began to write guiding notes for the projects he was responsible for. Of course, in order to improve their abilities, he would only tell them the direction at first, and give them guidance when they encountered difficulties.

With the current foundation and the experience or knowledge of later generations, Li Guocheng completed the guiding notes for all other projects in only three days.Just waiting to give it to each of them next Monday.
