In the golden month of October, the mood of autumn is getting stronger.
A large number of golden leaves are spread on the spacious roads in Xinghai Science and Technology Research Institute. It is very quiet here, with only flocks of birds chirping tirelessly.
Here in the Optical Laboratory of the Institute of Electronics, Liu Yuan and Li Chun are leading hundreds of researchers to study lithography machines.
"Haha, it's incredible. This method actually works. A beam of light can be split into more than 100,000 beams of light. After being enhanced, it can completely meet the needs of photolithography."
Li Chun looked at the latest research results and couldn't help laughing happily.
In his opinion, it was almost impossible to master all the technologies in the chip field from beginning to end.
Wafers, photolithography machines, ternary computer framework design, software architecture and development, etc., each alone is enough to be tackled as a major project. It requires a large number of scientists and engineers to gather together and study for many years.
It may not be possible to study it.
But now, in less than a year, Xinghai Science and Technology Research Institute has successively conquered wafer technology. Now the core and most critical technology of lithography machines has also been conquered.
Xinghai Technology is researching lithography machines. The technology they are studying is maskless lithography machine technology. The difficulty of this lithography machine technology is how to split a beam into thousands of beams.
The more beams that are split, the higher the accuracy of the chip produced.
Like Polar Bear, they also rely on imports for most of their chips, but in the field of military chips, they are not afraid of being strangled.
Because they have two maskless lithography machines developed by themselves, which also use this technology.
Although their technology can only achieve an accuracy of tens of nanometers, it is completely sufficient for military chips.
And their consistent style has always been that the leather is durable. As long as it can meet the needs, there is no problem at all. If the accuracy is not enough, they can also increase the amount of ammunition.
In short, in one sentence, the accuracy is not enough and ammunition needs to be scrapped. Even if the accuracy is only a few tens of nanometers, the chips they produce themselves are enough to meet military needs.
Of course, if it is to be used in the civilian field, this is obviously completely insufficient, the accuracy is not up to standard, and the product's qualification rate, cost and many other aspects are completely incomparable with others.
However, this does not mean that maskless lithography technology is not good. In fact, compared with ASML's mask lithography technology, mask lithography technology is equivalent to stamping out what you want on the wafer.
The required circuit is drawn out, and maskless photolithography technology is equivalent to using a large number of light beams to draw the circuit on it, which is equivalent to drawing out the circuit on the wafer.
In simple terms, this is somewhat equivalent to the difference between gravure printing and letterpress printing, which is roughly the same.
It is precisely by relying on the maskless lithography machine that he independently developed. Although it can only produce chips of tens of nanometers or hundreds of nanometers, Polar Bear can master its own military chips. Simple, practical and easy to use is enough. As for
In the civilian field, just give up completely.
"Polar Bear's maskless lithography machine technology can only divide a beam of light into more than 13,000 beams, so their accuracy can only reach tens of nanometers."
"But now our technology can divide a beam of light into more than 100,000 beams. Our accuracy can easily be more than ten times theirs, and we can reach the international advanced level of a few nanometers."
"And now is just the beginning. As long as we refine this technology, we may even be able to achieve a level of a few tenths of a nanometer in the future."
Wang Wei was also very excited. He was so excited when he thought that if the chip technology could be improved to a few tenths of a nanometer.
"Haha, it's completely possible."
"Now we have just started to develop this technology and we are already able to produce more than 100,000 beams. In the future, if we carefully refine it, it will be possible to split more than a million beams. By then, this chip technology will be able to break through to the picometer level.
."
Li Chun was also extremely excited. He had studied electronic technology all his life and had never been so happy and excited as he is now.
"It is entirely possible that we can build a super lithography machine!"
"The accuracy can easily reach the most advanced 2 nanometer level in the world. After upgrading, it can reach the picometer level. I can't imagine that once the chip can reach the picometer level, what will happen to the chip?
What will it become?”
"Super lithography machine?"
Liu Yuan also laughed when he saw everyone's excitement.
This technology is nothing at all. Among star-level civilizations and river-level civilizations, the use of light and energy has long been a passion. One of the most important technologies is energy weapon technology.
Among them, the most commonly used method is to use light to carry energy, and then use it for attacks. The speed of light is the fastest, and when it carries huge energy, it can often destroy enemies from an extremely long distance.
The technology that I have come up with in front of me is not even an introduction to energy weapon technology.
In the field of energy weapons, a beam of light is first split into countless rays of light, and then each beam of light is continuously increased to contain more powerful energy, and finally thousands of beams containing a large amount of energy are struck together to attack.
go out.
A seemingly simple beam of light has terrifying power, capable of easily destroying an interstellar battleship. Even at the peak of technology, even light can be made material for you, just like a sharp sword in the vastness.
Across the interstellar universe.
Nowadays, it is just using very crude technology to manufacture lithography machines and chips. It is nothing at all, but for the technology on the earth now, it is still an extremely advanced technology.
Splitting a beam of light into more than 100,000 beams, this technology alone has surpassed the most advanced optical technology. The more beams it splits, the finer things it can depict, easily surpassing the current international light beams.
Engraving technology.
From this point of view, compared with mask lithography technology, maskless lithography technology has more prospects and development prospects. This is why Liu Yuan wants to study maskless lithography technology.
On the one hand, the patent for mask lithography technology is in the hands of competitors. Even if you develop it, they still have the patent. If you want to use it, you have to pay the patent fee honestly.
The other is that the development potential of mask lithography technology has come to an end, and it is difficult to improve it. The current level has almost reached its peak.
But maskless lithography technology is different. As long as it can split more beams, its accuracy can be continuously improved. Nano-level is easy to achieve, and picometer-level technology is also promising.
.
In addition, it is to accumulate technology in the future.
When it reaches the stage of interstellar civilization, it will naturally be necessary to study light energy weapons. At that time, you will still have to study these technologies.
Now is the time to lay the foundation and prepare for future research on light energy weapons.
"This photolithography technology has achieved a breakthrough, and photolithography machines can be manufactured soon."
"In other words, we have overcome the two biggest problems in the field of chip technology. We can produce wafers ourselves, and we also have photolithography technology. As for other technologies, they are nothing."
"Haha, we will be able to produce our own chips soon!"
Li Chun did some calculations and immediately laughed happily.
For a scientist like him who has studied chip technology all his life, this is the most exciting and happiest thing.
Like the older generation of scientists, they can use their own efforts and struggles to fill in the defects and shortcomings of certain aspects of technology through their own wisdom.
The chip field has always been a pain in the hearts of fruit people.
Without its own chips, it relies heavily on imported chips. It spends more than 300 billion green coins to import chips every year. What a huge fortune this is.
The key is to forget about spending money, you will still be your grandson after spending money.
If they say they want to choke you, they will pinch you. If they say they won't sell, they won't sell. If they say they want to raise the price, they will raise the price. You can only endure it. There is no way.
Now that we have mastered advanced photolithography technology, we will soon have our own powerful chip. We will no longer have to be choked by others, and we will have a large amount of money left over. The key is that we will never have to worry about being choked by others again.
thing.
How could he not be excited and happy?
For a scientist like him, there is nothing more gratifying than this.
Think back on the path you have traveled over the years.
When he was young, he studied hard and went abroad to study. He also studied chip technology. He excelled in his studies and was hired by foreign companies with high salaries, but he was not tempted.
He came back resolutely with passion to serve the motherland.
It's just that he has wasted his whole life and has never been able to come up with his own chip. This has always been a regret in his heart.
This is also the reason why Liu Yuan was able to persuade him to give up everything and join Xinghai Technology, because he has a dream, that is to develop his own chip, and no longer be choked by others, and no longer tolerate it.
Their ugly faces really straighten their backs.
Originally I just came here with a dream, hoping to conquer some technologies through hard work. Who would have thought that it would only take so long, less than a year.
Under the leadership of Liu Yuan, we have successively conquered the two most critical technologies and have our own wafer technology and photolithography technology.
As for some other technologies, they are not too difficult at all and can be easily broken through and researched.
You will soon be able to create your own top-notch chip!
Thinking of this, Li Chun burst into tears. His dream will soon come true.
