Siheyuan: Starting from a fitter

Chapter 157 Chip Cost
"Okay, your rolling mill should submit a report as soon as possible, and this year's machine tool research expenses will be allocated to you," Dad Zhao suggested.

“Okay Dad, we’ll submit it as soon as possible”.

"Last time, most of the 100 101-type computers were delivered to the Northwest, and other units also applied for many times. So far, there have been more than 1000 computers in total. At the beginning of the year, a production task of 500 computers was issued. Will the subsequent production be 101 or 103? Type, can you give me some advice?" Dad Zhao asked.

“101型的制造成本应该是812元，103型的制造成本不会多于1000元。但是两种型号没有可比性。101型只能用于科学计算，无法存储数据。

Model 103 is a computer in the true sense. Based on the operating system and stored data, it can handle a lot of tasks, as I have just stated.And their monitors and chassis are the same, the only difference is the motherboard.”

"Dad, what do you think?" Father Zhao asked Mr. Xiang.

"The remaining 500 units will not be produced for the time being. I will talk to everyone first and then decide what to do," the old man replied after pondering for more than ten seconds.

"By the way, when will Type 103 be mass-produced?" the old man asked.

"It is expected that the national day will be finalized, and it should be capable of mass production in early December."

"I've always been curious, why are your chip prices so cheap?" Dad Zhao asked.

"Should the domestic production of single crystal silicon reach 2 inches now? We can now produce 3 inches. And we extract the single crystal rods in ultra-vacuum. During the heating process, most of the impurities are vaporized or Vaporized and then discharged directly out of the vacuum furnace.

The purity is directly 8 nines, and it needs to be purified again in China.During the chip production process, we have a dust-free workshop, but they do not.Our yield rate has always been above 9%, and they estimated it to be below 95%.

Our chip design will be verified repeatedly, and the production depends on sophisticated photolithography and etching machines.They are all done by hand.We have started LSI design, and they are still in the stage of small-scale integrated circuits at the level of discrete devices or 10 devices.

We can solve the same function with one chip, but they require thousands of devices.We can manufacture more than 30 chips on one wafer, but they can only manufacture 30 to 40 scattered devices.

Our production process has strict quality control procedures, and they are also manual workshops.Add all this up and it’s not surprising that their costs are hundreds of times higher than ours.”

The two of them took a breath of air and looked at each other.

"I didn't hear you say that today. I didn't understand that the gap is so big. I have learned a lot," the old man said with emotion, looking at Li Guocheng with even more satisfaction.

"In addition to equipment and environmental problems, are there any other problems?" The old man then asked.

"Philosophy. Our workers have very high ideological consciousness and obedience. But our philosophy is to save as much as we can, and we are not willing to invest in the working environment.

The construction cost of our dust-free workshop can be earned with a radio production line. Of course, we do not make money from our brothers' units, but by analogy.If we purchase a production line with the same technology content from the West, how much will it cost? "

"It can't be compared. Last year, the cost of abandoning East Germany's one-generation backward semiconductor production line was more than 100 times that of the radio production line. The problem is that they are not willing to sell it yet. If the CNC machine tools are solved, our industrial system can be slowly built." , Father Zhao said with emotion.

"The 103-type computer seems to be unable to be exposed. Now that there are strong enemies around, we can't stimulate them for the time being," the old man said thoughtfully.

"Build walls high, accumulate grain widely, and become king slowly."

"Hahahaha...", the three of them laughed heartily.

When he went to work the next day, Li Guocheng mentioned the machine tool cost report to Wu Liankui.Then a morning meeting was held for the semiconductor laboratory.

"Comrades, we communicated with the factory leaders yesterday. Next, our main work goal is the research and application of computer technology. And the first choice target for application is definitely our machine tool design.

In computer technology research, the primary goal now is the design of operating systems, which is headed by Zhang Zhijing.Machine tool We choose 3-axis CNC machine tool for research.Do you have any comments? "

As soon as she finished speaking, Zhang Zhijing raised her hand to speak: "Can you tell me the specific time requirements?"

"The design task of the first version of the operating system must be completed by the end of September and must pass the test."

"There are only more than 4 months. I will make a schedule first and then report to you."

"CNC machine tool research, which part of the work is our laboratory responsible for?" Zhou Xiaojuan asked suspiciously.

"I am responsible for the software aspect, and Wang Gong is responsible for the mechanical structure," Li Guocheng replied.

"What is the direction of materials research?" Zhou Xiaojuan asked.

"What is more urgent now is the research on luminescent materials. I have already told you the principle, which is to release energy to emit light through the recombination of electrons and holes, and to obtain different colors by doping with different materials.

The basic materials are made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc.How to experiment, you can contact Zhang Tou or Wang Dayong."

"I have no problem," Zhou Xiaojuan said.

"Brother Li, what is the next step of the lithography machine's work?" Yan Jiefang asked when he saw that no one was talking.

"You change the movement mode of the lithography machine from manual control to automatic control. If you ask for it, I will consider how to realize it."

"OK".

"Where are the others?" After waiting for a few seconds, "If there is no opinion, the meeting will be adjourned."

Everyone gets busy.

Three days later, Wu Liankui hurriedly walked in and said, "Old Li, let's go, Director Li has invited me."

Entering Li Huaide's office, Wang Gong was already sitting on the sofa.

After exchanging pleasantries, they each sat down.

"Comrades, we have just received a notice from our superiors, announcing two things. First, all comrades in the laboratory will be given special allowances, ranging from 10 yuan to 30 yuan; second, the safety level of the steel rolling mill laboratory will be raised by two levels. A squad of security personnel was stationed."

The three of them looked at each other and showed happy expressions.

"For the sake of safety, a family building is built on the east side of the laboratory, and people in the laboratory will live in it in the future."

"What about family members going to and from get off work?" Wu Liankui asked.

"In the future, work will be transferred one after another, and the rolling mill, machine tool factory and laboratory can all be arranged," Li Huaide said with a smile.

All three breathed a sigh of relief.

"It's still the leader's consideration." Wu Liankui hurriedly flattered him, and Li Guocheng and Wang Gong nodded frequently.

"You guys," Li Huaide smiled and pointed at the three of them.

"I didn't expect that the leader would pay so much attention to the laboratory. He also said that the name brands of the five production lines have been changed to English, and the manufacturer is "Chou Guo Company". And a hush order was issued, hahaha",
Several people also laughed, thinking that the leader was too good at playing pranks.
