In fact, he didn't know that he was a full man and didn't know that a hungry man was hungry, and that his accuracy of 50 or 60 nanometers was now the world's first! Before the invention of ultra-deep ultraviolet lasers, Europe and the United States were still in the U-meter era.

When the software engineer of SoftNews heard him say that the boss asked for less than 10 nanometers, he said, "I'll change the program again." ”

It turned out that he took a trick and directly applied the system control program used in the original chip production, but the lasers used to produce the chips were in a row, and it was enough to irradiate and scan only once. And this AMOLED screen dedicated lithography machine has only one laser head, using the same progressive scanning technology as a dot matrix printer, because the system control program is not very matched, of course, the error in the middle is large. Originally, the lithography accuracy of the ultra-deep ultraviolet laser can reach a maximum of 10-15 nanometers, which is several times higher than the accuracy of 50 or 60 nanometers.

Since it was the boss who personally requested it, he didn't dare to take a trick, so he hurriedly went to change the program.

It must be noted here that there is no upper limit to the mechanical accuracy, which can reach a maximum of 2 nanometers. This is because they have adopted non-contact rail linear motor technology, changing the mechanical accuracy to electromagnetic control accuracy.

It took a lot of effort for the software engineer to finally modify the program. He sighed again, relieved the pressure in his heart, and then said, "It's okay, let's try again!"

This time, the engineer of the physics research institute was no longer so lively, he did not answer, and without saying a word, he tried to engrave again, and a few minutes later, he picked up the AMOLED screen used for the experiment and went to the high-powered electron microscope to observe. This time, the effect is much better, but it is still only 20 nanometers accurate, which still cannot meet the boss's requirements. So he said to the software engineer, "Can you do it again, and the lithography is only 20 nanometers." ”

"Okay! I'll tune it again," the software engineer replied.

At this point, the mechanical engineer spoke, and he said to the two, "It's fine to adjust it again, but that's not enough, you have to add a focus lens." Because the lithography accuracy of the ultra-deep ultraviolet laser is only more than 10 nanometers. ”

After he finished speaking, he took a piece of glass and walked towards a nano-level machining precision CNC combination machine in the workshop. This is where Changsheng Investment Group is awesome, if other companies want to process this focused lens, it is not much more difficult than picking the stars in the sky, it is the same can't be done. But they just need to start the machine and set some parameters.

Here I would like to explain again, don't be deceived by the exquisite craftsmanship of some senior optical craftsmen in Germany, and it is not really deceived, there are such top craftsmen. But the highest precision a person can achieve is the filament level. Silk is also a unit of length, that is, 0.01 millimeters, everyone imagine, to be divided into 100 points within a millimeter, it is only a minimum scale, most people have to use a microscope to observe this unit, but the top craftsmen can find this subtle unit with their eyes and hands. It's remarkable. But one nanometer is one ten-thousandth of this unit of length, and if you don't use instruments and only manual labor, unless you are an immortal, you can observe it, let alone process it. So what craftsmen are scum at the nanometer level, just like us ordinary people, there is nothing to do. And Changsheng Seiko's nano-level CNC combined machine tool can do it, so the engineer of the Institute of Mechanical Technology casually processed a focused lens, the world's enterprises have no way, not at all German Chase optics can be compared, this is the absolute crushing of technology, not an order of magnitude at all.

In just 5 minutes, the mechanical engineer preliminarily processed a focused lens and walked over. The software engineer hadn't been able to adjust the data parameters so quickly, so the mechanical engineer took the opportunity to modify the laser lens.

It may seem simple to say, but there is a top-notch technology that supports his work. This is another black technology developed by Changsheng Seiko, the predecessor of Shen Danqing Mechanical Technology Research Institute. He was inspired by the digital mapping technology of the former Soviet Union in his previous life. That is, the space is divided into a three-dimensional grid, and the three-dimensional three-dimensional pattern of the object is determined by the laser scanning machine. Of course, Changsheng Seiko has undergone technological upgrades to achieve this measurement accuracy of one nanometer. Far from being comparable to the measurement accuracy of the former Soviet Union.

What is the use of this technology? The engineer can tell if the focusing lens he has installed is wrong without the help of an optical instrument such as a microscope, and he can see it from the numbers on the display. All this is because of the help of laser scanning and positioning technology, which scans this three-dimensional data and displays it on the display screen with intuitive numbers. Of course, assembling such precision parts is not assembled by hand, but by using an automatic robotic arm. The engineer simply sets the parameters. The robotic arm does everything else, and it adjusts the mounting of the focusing lens based on the scan results, which is the charm of technology. Turn decay into magic, what others can't do, you can do it with a raise of your hand.

An extremely deep ultraviolet laser beam cannot be seen by the human eye and must be seen with the help of a high-powered electron microscope. Because its beam is so thin, as thin as one thousandth of a hair. Mechanical engineers use a high-powered electron microscope to observe this beam to see if it meets the requirements of less than 10 nanometers. Optical focusing is at the nanometer level, and it is very difficult to focus twice. Mechanical engineers not only have to adjust the lens mounting, but sometimes they also have to grind the lens in order to achieve twice the focus. He kept revising, installing, and observing, and finally tuned it to twice the focus that satisfied him.

The software engineer has also adjusted it, and it takes a lot of mental energy to make such a subtle parameter adjustment, as if he has just finished heavy physical labor. Exhausted, he said weakly, "It's okay, you can try again!"

The engineer of the physics research institute had been waiting impatiently for a long time, and when he heard the software engineer say that it was okay, he immediately put the trial substrate that had been prepared into the lithography machine for trial engraving. A few minutes later, he got the high-powered electron microscope and found that it had finally met the requirements, and the lithography accuracy was six nanometers. He jumped up for joy, his face flushed as if he had just finished a sport. He is so happy that he is not only expected to complete the task assigned by his boss, but also get a good bonus.

"Thanks, when I officially engrave a few substrates, I will invite you to a big dinner, wherever you want, you can choose. He said gratefully to the two tired engineers.

Ion implantation and surface coating, their institute has already prepared, they already have these precious equipment, but the size of the target chamber is not suitable, so they temporarily modified it.

In this way, the Institute of Physics finally made several AMOLED screens with six-nanometer lithography accuracy within the three-day deadline specified by Shen Danqing. is the reason why Hu Weihong reported the good news to Shen Danqing mentioned above.

Hu Weihong's good news is indeed too good news for Shen Danqing. He immediately jumped up excitedly, "Good, good, good!" He said three good words in a row, and he said to Hu Weihong in a tone that was trembling with excitement: "Director Hu, you work harder, immediately set up an emergency technical group headed by you, bring together the top engineers of the Electronics Research Institute, Soft News Company, and Mechanical Technology Research Institute, make these AMOLED screens, and try the lithography effect, if qualified, immediately replace all the laser heads of the lithography machine, including the LCD screen, and finally tell me the news." Did you hear me clearly?"

"Boss, I heard me clearly, and I will do what you say immediately. Hu Weihong reacted like a spring and immediately assured Shen Danqing. It was the first time he had seen his boss in such an urgent mood, so he used twelve points of vigilance, for fear of angering the boss. At this time, the boss is the most sensitive, and he can't tolerate the slightest disobedience from others.

"Well, I'm waiting for your good news. Shen Danqing hung up the phone after speaking. He didn't want to waste even a second, so he didn't say more, so that Hu Weihong could hurry up and do it.

This matter is so important that Shen Danqing didn't dare to participate in the experiment in person, yes, he was just afraid, afraid that if it didn't work, then he would be hit too hard, and he was afraid that his emotions would get out of control on the spot. He couldn't help himself at this point, so he might as well sit in the office and wait.

The reason why Shen Danqing is so excited is because this technology is so important. "Direct lithography" is only a simple four words, which may seem simple to say, but in fact it is a hurricane-level technological revolution. It will reduce the cost of chips by more than half, and it will shorten the time of the process of chips from drawing to tape-out to mass production of finished products by several months to half a year. Any one of the changes is amazing, not to mention the two, if it really happens, then Changsheng Investment Group will be able to crush foreign chip companies. Of course, I can't see it now, because now Changsheng Investment Group can only produce low-end chips, just like a beggar with a golden job bowl can only beg for food.

Shen Danqing realized that this direct lithography technology was a thick gold finger for Changsheng Investment Group. Then the level of secrecy of this technology is about to be mentioned to the highest, and he can't pay too much attention to it. Besides, he will have many black technology inventions in the future, all of which cannot be known by outsiders. Then the time has come for a strict internal secrecy regulation. He pondered in his mind what regulations should be enacted, who should participate in the formulation of them, and which unit should be responsible for implementing and supervising them.

Now his heart was terrifyingly calm, and the excitement he had just now had long since disappeared. When it comes to the life and death of the company, he must think maturely with the most rational thinking, and he will not allow the slightest loophole. In this way, Shen Danqing fell into deep contemplation.
