Chapter 399: No time to talk to bragging guys

In chip manufacturing, what process is used is a big technical indicator. For example, in later generations, the process has been developed to 10 nanometers, and even 1 nanometer has been tried in the laboratory. The smaller the value, the more valuable.
What does it mean?
The CPU manufacturing process refers to the processing of various circuits and electronic components, and the manufacturing of wires to connect various components during the production of the CPU. The number of nanometers in the manufacturing process refers to the distance between the circuits in the IC. (There are also sayings that the width of this wire, or the width of the gate circuit of the most basic functional unit on the chip.).
In short, the smaller the value, the denser the internal circuits, which means that in the same area of ​​the IC, you can have a higher density and more complex circuit design. At the same time, the most expensive is the wafer. If more circuits are integrated, it also means that the cost can be reduced.
The development and progress of microelectronics technology mainly depends on the continuous improvement of process technology. The chip manufacturing process started in 1971 and has experienced 10 micrometers, 6 micrometers, 3 micrometers, 1.5 micrometers, 1 micrometers, 800 nanometers, 600 nanometers...and the subsequent 10 nanometer technologies.
Now, in Qin Guan's impression, he felt that Nano was the basic unit. Who would have thought that his question made Wang Lao think he was here to humiliate himself.
"Our current process is 10 microns." Wang Lao said: "If you say nano, it would be 10,000 nanometers."
10 microns, the technology level achieved by foreign countries in 1971, when Intel’s first-generation CPU4004 used 10-micron technology. Now, almost ten years have passed, and the 10-micron technology level is still adopted in China.
At this level of technology, it is impossible for the designed and manufactured chips to have great development prospects.
Qin Guan frowned, and at this moment, he had entered the brain system.
Start, machine graveyard!
If you want to improve the domestic processing level, you need to exchange the industrial mother machine, that is, the machine tool!
After unlocking the machine tool cemetery, Qin Guan introduced a high-precision CNC machine tool to complete the processing of the most precise high-pressure oil pump in the heavy truck engine. Now, what Qin Guan is looking for is a machine tool that produces chips.
The machine tool is a general term. In the production of cpu, the etching machine and the lithography machine are the most important parts. These can also be regarded as machine tools in a broad sense.
In the chip processing process, lithography machine stake out, etching machine construction, cleaning machine cleaning. Then repeat the cycle dozens of times, usually about 500 processes, the chip-that is, the integrated circuit of the transistor can be completed. (Of course there are coating processes, so I won’t talk about it.)
In later generations, this kind of machine can also be produced in China. Although it cannot be compared with the advanced level of foreign countries, it can reach a relatively high level. For example, the Changchun Institute of Optics and Mechanics has achieved a breakthrough in "extreme ultraviolet light" technology, which can reach 22-32. Around nanometers.
It is impossible for a lithography machine of this level to enter the graveyard. In the 1990s, for example, the most representative 80486 chip used a 1 micron process, and later a 0.6 micron process. This 1 micron process has completely fallen behind in later generations, even The lowest-end chips have begun to have a process of tens of nanometers, so the previous equipment has been eliminated.
Compared to later generations, it is backward, but compared to this era, if a 1 micron process is used, it will definitely be a bunker. Leading foreign countries for more than ten years.
Find it now!
The leading lithography machine is ASML, but Qin Guan does not want to use foreign lithography machines.
Yes, this is the pride, honor and disgrace in his heart, or it is a little anger at work.
In later generations, seeing that the chip industry was blocked, the country started independent research and development. In order to make a breakthrough, when the domestic chip manufacturing process had reached the level of 20 nanometers, suddenly the foreign monopoly was lifted.
The ASML lithography machine manufacturer owned by Eagle Country suddenly declared, when did we monopolize Han Country? We have never said before, now, we can provide it to you!
Therefore, the 7-nanometer technology lithography machine was actually shipped to Han and sold to a chip company in Han. The intention behind this is too obvious.
This is not the first time a foreign country has done this. If you don’t have it, you will be technically blocked. You can only spend a large amount of money to buy the finished product. When you are about to develop it, then it will not be blocked. To you.
In this way, your self-study road is blocked.
Your self-developed level is only 20 nanometers. I will export the 7 nanometers to you. Yours is immediately behind. At the same time, you have to spend a lot of research and development funds. The transition from 20 nanometers to 7 nanometers requires a huge amount. Invest, in this way, the comprador class in Han will chant the usefulness of imports, and then block the road of domestic self-research once again.
Foreigners can do such a thing with ease. In short, it is to block your self-research path. You already have a 7-nanometer one. Throw away the 20-nanometer one. Later, when foreign technology advances, it will reach 1 nanometer. , Even when it was 0.1 nanometers, Han was behind again.
Qin Guan didn't want to use foreign ones. He wandered around in the domestic machine tool cemetery. Anyway, when he entered the system, the time outside did not pass by.
Finally, he found a prototype in an empty corner.
Lithography No.1, 1 micron process, the lithography machine product prototype developed by Han Guo Microelectronics Equipment Co., Ltd. in 2006, due to the backward performance, after the development, it only exists as a prototype and began to develop more advanced The lithography machine finally reached the level of 90 nanometers.
At this time, this lithography machine was quietly in a corner of the cemetery, witnessing the development and changes of microelectronic technology in Han.
Qin Guan did not exchange immediately, but left the cemetery.
At this moment, the expression on the face of the prince in front of him is still ugly, are you here to make fun of people?
Seeing that Mr. Wang was upset, I wish Mr. Zhu wanted to dissuade him from the sidelines. Qin Guan definitely didn't mean that. He must be unintentional. Besides, I don't understand what you are talking about.
"I can improve our 10-micron production equipment to 1 micron production equipment." Qin Guan said: "Using this new technology, our current 4K memory can directly double the performance."
"Hmph, I have no time to talk to you, wasting time." Wang Lao looked at Qin Guan in front of him and didn't believe it at all.
10 micron to 1 micron is a zero thing, but even Eagle Country has used it for more than 10 years! From 10 micrometers in 1971, it was 1 micrometer in the mid-1980s.
Where did Qin Guan come from? Never seen him before.
The more special the industry, the narrower the circle. For example, Wang Lao, the world's top chip development man, he knows, but has never known Qin Guan.
