MTL - The Rise of Space Technology-Chapter 112 , super lithography machine

   Chapter 112, Super Lithography Machine

  The golden autumn is October, and the autumn is getting stronger.

   A large number of golden fallen leaves are spread on the spacious roads in the Xinghai Science and Technology Research Institute. It is very quiet here, only flocks of birds are tirelessly chirping.

  The Optical Laboratory of the Institute of Electronics Research Here, Liu Yuan and Li Chun are working on lithography machines with hundreds of researchers.

   "Haha, incredible, this method actually works. A beam of light can be split into more than 100,000 beams of light, and after enhancement, it can fully meet the needs of lithography."

  Li Chun looked at the latest research results, and the whole person couldn't help laughing happily.

   Originally, in his opinion, it was almost impossible to get through all the technologies in the chip field from start to finish and from scratch.

The frame design, software architecture and development of wafers, lithography machines, ternary computers, etc., alone are enough to be conquered 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 already conquered wafer technology, and now the core and most critical technology of lithography machine has also been conquered.

  Xinghai Technology is researching lithography machines. The technology studied 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    are split, the more precise the resulting chips will be.

   Like polar bears, most of their chips are imported, but in the field of military chips, they are not afraid of being strangled.

  Because they have two maskless lithography machines developed by themselves, they also use this technology.

  Although their technology can only achieve an accuracy of tens of nanometers, for military chips, this is enough.

   And their consistent style has always been that they are solid and durable. As long as they can meet the demand, there is no problem at all. If the accuracy is not enough, they can also increase the amount of ammunition.

   In short, the accuracy is not enough, and the ammunition needs to be collected. 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 not enough, the accuracy is not up to standard, and the qualification rate, cost and many other aspects of the product are completely incomparable with others.

However, this does not mean that the maskless lithography technology is not good. In fact, compared with ASML's mask lithography technology, the mask lithography technology is equivalent to pressing out what you want on the wafer. The required circuit is produced, and the maskless lithography technology is equivalent to using a large number of beams to draw the circuit on it, which is equivalent to deducting the circuit on the wafer.

   In simple and popular terms, this is somewhat equivalent to the difference between gravure printing and letterpress printing, which is roughly the same.

It is precisely with the maskless lithography machine independently researched that although it can only produce chips of tens of nanometers or hundreds of nanometers, polar bears can master their own military chips. Simple and easy to use is enough. As for In the civil field, it is enough to give up completely.

   "Polar Bear's maskless lithography machine technology is only able to divide a beam of light into more than 13,000 beams, so their accuracy can only be tens of nanometers."

   "But now our technology can divide a beam of light into more than 100,000 beams, and our precision can easily be more than ten times that of them, and it can reach the international advanced level of a few nanometers."

   "And now is just the beginning. As long as we fine-tune this technology, it can even be possible to achieve the level of a few tenths of a nanometer in the future."

  Wang Wei was also very excited. When he thought that the chip technology could be improved to a few tenths of a nanometer, the whole person was ecstatic.

   "Haha, it's entirely possible."

"Now we have just started to develop this technology, and we have already been able to achieve more than 100,000 beams. In the future, it is possible to split more than one million beams. The chip technology can completely break through to the picometer level. ."

   Li Chun is also very excited. He has studied electronic technology for a lifetime, and he has never been so happy and excited as he is now.

   "It is entirely possible that we can create a super lithography machine!"

"Accuracy can easily reach the world's most advanced 2-nanometer level, and after upgrading, it can be achieved at the picometer level. I can't imagine that once it can achieve a picometer chip, the chip will change. what kind of."

   "Super lithography machine?"

  Liu Yuan laughed when he saw everyone's excitement.

  This technology is nothing at all. The use of light and energy in star-level civilization and river system-level civilization has long been pure and innocent. One of the most important technologies is energy weapon technology.

   Among them, the most used is to use light to carry energy, and then use it for attack. The speed of light is the fastest, and it carries a huge amount of energy, which can often destroy the enemy at an incomparable distance.

   The technology that he has brought out in front of him is not even an entry point in the face of energy weapon technology.

In the field of energy weapons, a beam of light is first split into countless beams 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 hit together to attack go out.

A seemingly simple beam of light is extremely terrifying, enough to easily destroy an interstellar battleship, and even when the technology reaches its peak, even light can be substantiated for you, like a sharp sword in the vastness. Across the interstellar universe.

   Now it is just using very shallow technology to manufacture lithography machines and chips, which is nothing at all, but it is still an extremely advanced technology for the technology on the earth today.

Splitting a beam of light into more than 100,000 beams, this technology alone has surpassed the most advanced optical technology. The more beams split, the finer things can be depicted, easily surpassing the current international light engraving technique.

   In this regard, compared to mask lithography, maskless lithography is more promising and promising, which is why Liu Yuan studies maskless lithography.

   On the one hand, it is because the patent of mask lithography technology is in the hands of competitors. Even if you research it, they also hold 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 any more, and it is almost reached to the current level.

But maskless lithography technology is different. As long as more beams can be split, its accuracy can be continuously improved. It is easy to do it at the nanometer level, and the technology at the picometer level is also promising. .

   In addition, it is to accumulate technology in the future.

   When you reach the stage of interstellar cosmic civilization, you will naturally need to study light energy weapons. At that time, you will still have to study these technologies.

   Now is the time to lay the groundwork for future research into light weapons.

   "This lithography technology has made a breakthrough, and the lithography machine can be manufactured soon."

   "In other words, we have overcome the two biggest problems in the field of chip technology. We can produce wafers by ourselves, and we also have lithography technology. As for other technologies, they are nothing."

   "Haha, soon we can produce our own chips!"

  Li Chun calculated a little, and immediately laughed happily.

   For a scientist like him who has been studying chip technology all his life, this is the most exciting and happiest thing.

   Like the older generation of scientists, through their own efforts and struggles, they can use their own wisdom to fill in the defects and deficiencies of certain technologies.

  The field of chips has always been a pain in the hearts of fruit people.

   Without its own chips, chips rely heavily on imports, spending more than 300 billion green coins to import chips every year, what a huge fortune.

   The key is to spend money, you are still your grandson.

   They say they will choke you if they choke you, if they say they won’t sell it, they won’t sell it, if they say they will raise the price, they will raise the price.

Now that I have mastered the advanced lithography technology, I will soon be able to have my own powerful chip, and I will no longer have to be strangled in the future, and I will have a lot of money left. The key is that I will never have to worry about being strangled in the future. thing.

   How could he not be excited, how could he not be happy.

   For a scientist like him, there is nothing more gratifying than that.

   Think back to the road you have traveled over the years.

   He studied hard when he was young, and went abroad to study. He still studied chip technology. He studied well and was retained by foreign companies with high salaries, but he was not tempted.

   With a passion to serve the motherland, he came back resolutely.

   It was just a waste of his life, and he was never able to come up with his own chip, which was always a regret in his heart.

This is also the reason why Liu Yuan was able to persuade him to give up a lot of everything to join Xinghai Technology, because he has a dream, that is, to come up with his own chip, and no longer be strangled or endured Their ugly faces are really straight.

   Originally came here with a dream, hoping to overcome some technologies through hard work. Who could have imagined how long it would take, less than a year.

  Under the leadership of Liu Yuan, everyone has conquered the two most critical technologies one after another, and has their own wafer technology and lithography technology.

   As for some other technologies, it is not too difficult at all, it is easy to break through and research.

   Soon you can make your own top chip!

  Thinking of this, Li Chun has some tears in his eyes, his dream will soon be realized,
