Chapter 286: Test lithography machine

The Chinese Academy of Sciences, China's highest-end research institute, is located in the Optical Lab of Yanjing. Many experts are gathered here.
Vice Minister Wu Yanyu of the Ministry of Science and Technology also brought engineers from the Ministry of Science and Technology to come here.
Today Academician He Wanming brought a prototype of the lithography machine that will be put into production from Qingci Technology. They tested the machine.
The performance of this machine will affect the strategic layout of the China chip industry led by the Government Council.
He Wanming watched the tightly packed lithography machine being carried to the dust-free laboratory next to it.
He said with emotion: "I have been paying close attention to the research and development projects of lithography machines for clear porcelain technology.
It's only been a while now that prototypes have been made. I remember the development of etching machines. With their decades of technical accumulation, it took two years to develop successfully. "
"The times are different, as long as the foundation is laid. Products can be manufactured quickly.
One is the advancement of materials science. Now many new materials have been developed. One new material can solve the problems that could never be solved before.
The other is the advancement of processing technology. Today's intelligent CNC machine tools and 3d printing technology can easily process complex parts. We were working on a piece of equipment at that time, and we needed nine-level fitters to machine parts by hand. "
Standing among the crowd, an old man with gray hair said. He is Mr. Ou Jingyu, the developer of Huaxia's first generation lithography machine.
At that time, I only looked at foreign public information, and groped on my own in a poor situation. The problem of lithography machine is solved, and the country can produce a large number of industrial chips such as single-chip microcomputers.
Wu Yanyu said with a smile: "Let's take a look at the performance of this lithography machine. No matter the speed of research and development is fast or slow, it is the most important to be able to process high-quality chips."
He Wanming nodded and smiled: "It should be like this, we don't have to think too much now. Start testing this lithography machine now."
He Wanming then ordered the staff to test the lithography machine.
After the box is thoroughly cleaned with special tools, the robot sends it to the clean room.
After the robot opened the box, the lithography machine inside was immediately exposed.
Seeing the appearance of this lithography machine, someone whispered immediately: "The appearance of this lithography machine is too ordinary, it is a large box with a thin iron sheet, without any sense of technology."
The robot then puts the prepared semi-finished carbon-based semiconductor into the feed port of the lithography machine.
Only to see the lithography machine start up immediately, the box began to unfold. Above the lithography machine, it seems that flowers are in full bloom, and a stand device is stretched out.
He Wanming introduced: "This is the most important part for processing chips. The laser emitter is superimposed. It uses elastic metal as a skeleton and consists of 13 laser emitters. Through the control of the lithography system, the chip can be processed at any angle.
This system, which I led the research and development, can definitely reach the world advanced level. It's not just processing that we are preparing to carbon-based chips. There is no problem processing 7-nanometer silicon-based chips. "
"Lao He, don't brag about your achievements. Start the lithography machine soon, everyone can't wait." He Wanming's colleagues urged.
"Okay, okay. I'll start the lithography machine now. Its processing process is very fast and I can't see anything. I'm still ready to test the performance of the processed chip." Academician He Wanming immediately agreed to him.
He then took out the remote control and started to remotely control the start of the lithography machine. Set the processing standard of the chip.
Only seeing the raw materials and finished chips in and out of the lithography machine, the prepared raw materials are processed soon.
Wu Yanyu saw that the lithography machine had processed the smart chip.
She smiled for a long time. This basically confirms that the lithography machine has been successfully developed.
The impact of this device on the country is too great. Even if the smart chip is not processed successfully. But having a lithography machine in hand is also a great achievement.
Finally saw the chip successfully processed by the lithography machine. Everyone warmly applauded.
Wu Yanyu said with a smile: "This lithography machine is really fast. We can now test the performance of the lithography machine and its processing chip separately."
After she had finished speaking, the scientists and engineers standing next to each other were eager to try and selected several smart chips that had just been processed for testing.
The project they tested did not require packaging the chip.
When He Wanming heard this, he immediately stopped their actions and said, "What are you so impulsive about? You still need to package and activate the chip before you can test it.
Of course, there are many processed chips. If you do not test the overall chip performance, you can also choose the chip test first. "
He Wanming then took out a small box and placed it next to the chip. He said to everyone: "People who test the overall performance of the chip, don't be too anxious. The chip has not been packaged yet. After the chip is packaged, the chip is mounted on this small box. It will automatically write the startup program, otherwise It's a scrap. "
Everyone understands that after hearing this, this should be a patent protection method for chip development companies.
Wu Yanyu first stepped forward and chose a chip. These chips are the same, they have just been processed from the lithography machine and have not been packaged.
It's just a black and faint carbon-based original, and special equipment is needed to package them, integrating some internal circuits and external pins. This is the complete chip.
One scientist, he picked up the chip and said, "The chip I choose doesn't need to be packaged, mainly to test the performance of carbon-based transistors."
With the action of this scientist, there are many people who are mainly testing the performance of the chip construction.
They directly selected the unpackaged smart chip and quickly walked to the laboratory for testing.
When they finished selecting chips, some staff took the chips away for packaging. The chip after activation is activated again
They then distributed the chip to people in various units and let them test the performance of the chip.
Smart chip processing was completed, and He Wanming did not leave the lithography machine idle. Change its working mode immediately.
Processing of world-class chips, seven nanometer silicon-based chips. The selected processing scheme is a microstructure developed by Godson International.
He Wanming and Wu Yiyu etc. are here to summarize the data. UU reading books www.uukanshu.com
There are many ways to test the performance of a chip. Soon the news will gather in their hands.
The basic structure of a smart chip, a carbon-based transistor is three times the power of an ordinary silicon-based transistor. Power consumption decreased by 30%.
The basic performance of other chips also exceeds silicon-based chips in a wide range.
Carbon-based chips have also been tested, and good news is also coming. Its performance is not inferior to the top chip in the world.
There is also a strong compatibility, which can be compatible with most software and hardware.
Carbon-based chips, in particular, have hardware intelligent circuits. Changed the way conventional chips judge data. Artificial intelligence programs can be better developed on this chip.
He Wanming held the silicon-based chip already packaged in his hand. After testing, the track chip has reached the international mainstream level.
This lithography machine passed their test perfectly.
