Chapter 1402

The picture in front of them is clearer than the ultra-high definition picture quality in some movies. After all, the computers they use are not bad. Although they use not the graphics cards used by ordinary game players on the market, but the graphics and image graphics cards, it is also easy for these graphics cards to achieve such a picture.

However, such things like scenery make them feel at a loss. After all, this is not quite the same as what they imagined. What they imagined should not be pages similar to various software, with data input windows and command boxes, and then they input data, and then wait for the program to give the data they need?

At least they think so in their mind, but now after connecting, there is a picture similar to entering the game. What ghost is it?

But soon they found that there were different menus around the page. When they put the mouse up, they finally found something familiar to them. For example, they could set up the factory they needed here.

The factory has the 3-nanometer lithography machine production line they want.

After all, they are all high-tech talents. At first, they are just not proficient. Now, after adapting to it, it is actually simple. There are options they input in the setting. After they input and establish a production line of 3-nm lithography machine.

On the picture in front of them, there was a startling change. A production plant of lithography machine rose directly, and then a variety of production lines appeared in the plant.

As the most advanced research institute in China, they have actually seen these two things. In fact, chip design and lithography machine design are not the same job, but from another point of view, they are also a job.

At least in their research institute, there are two groups studying this, and now both of them are conducting relevant tests in this regard.

When a 3-nanometer lithography machine production line appeared, although the chip design team was surprised at the changes in the picture in front of them, they didn't care about these pictures at first. In their view, this picture was nothing more than a software program designed to show them. It didn't work, that's all.

Their concern is that after the establishment of the lithography production line, a drawing input page similar to the real production line appears on their page.

Here they can input all the chip parameters and drawings they have designed, and then the 3-nm lithography production line can produce the products they need.

Whether the product is successful and its performance can be further tested.

In fact, there is no 3-nm lithography production line in the world, but there are similarities between 3-nm and 7-nm in some aspects. If you choose 3-nm production line here, the whole production line can be used for production.

Their research institute has actually come up with a 7-nm lithography machine, and even a 3-nm lithography machine.

The reason why there is no way to use it is that whether it is 7 nm or 3 nm, their yield is simply terrible, and they can't be used in reality, because the price is too high, and the price of the chip is simply unbearable. How can such a lithography machine be competitive?

But in the dreamland simulation program or Pangu program, there is no problem. Anyway, these are data simulation. What if the yield is only 1%? Anyway, they are to test the performance of the chip.

The progress of another group of lithography machine design team is much faster. In reality, they have designed a 7-nm lithography machine, but the yield is too touching, so the lithography machine is just to have a look. There is a gimmick, which has no practical value.

After all, the 7-nm lithography machines of foreign companies have long been purchased and produced by OEM factories. Warwick's mobile phone chips have been produced by 7-nm manufacturing technology for several generations. Their lithography machines are simply throwing money to improve the country's technical reserves in this regard.

Because there is no income from other sources, the improvement of lithography machine must be slow. It can not produce enough chips. The speed of finding problems is naturally slow, because they want to save money.

But in this program, they can produce unlimited, and the amount of production is just a simulation data.

Only in the production process, the input data of the 7-nm lithography machine designed by them are carried out with reference to the actual production data reaction, including the procedures used by these lithography machines.

So in the process of unlimited production, the problems that can break out naturally continue to appear.

The whole lithography design team immediately began to adjust their own lithography machines according to these problems. Many devices are used enough to find problems.

Because Jiang Yanhai is near the scientific research institute, the speed of two eggs calling data is very slow, and the results given in the mirage simulation program are also very fast.

In just over two days, the yield of the 7-nm lithography machine designed by the lithography machine design team of the scientific research institute has increased from less than 40% simulated by the program to 90%!

The yield of 90% is still a little low in reality. For example, the yield of some OEM enterprises is at least about 95%, and even 98% can be achieved through skilled personnel and equipment adjustment.

However, the 90% yield, especially the domestic chip manufacturing which has always been in the international backward technology, has great production value!

The reason why the speed is so terrible is that they find any problem here. As long as they put forward a solution, the adjustment of the lithography production line can be completed in minutes by inputting a few data.

But in reality, you have to at least re produce relevant parts, which takes more than a little time. Here, you only need to change the data, and the simulated parts can be formed in an instant.

With a yield of 90%, the lithography design team is no longer ready to continue the design, mainly because they have not used the program and do not know whether the program is reliable, but all the data transmitted by the program are very accurate in their opinion.

There is only one reason why they stopped. They should produce one in reality according to this latest improvement, and then test it in reality!

Compared with the progress of the lithography design team, the progress of the chip design team is naturally slower. After all, chip design is something from scratch, and the lithography is more like upgrading.
