Chapter 1397 Progress

The picture that appeared in front of them was clearer than the ultra-high-definition picture quality in some movies. After all, the computers they used were not bad, although they were not using the graphics cards used by ordinary gamers on the market, but graphics graphics cards , but it is also very easy for these graphics cards to achieve such a picture.

But something like this scenery makes them feel a little bit at a loss. After all, it is not quite the same as what they imagined. What they imagined should not be a page similar to various software, with windows for data input and Command box, and then they enter data, and then wait for the program to give them the data they need?

At least they think so in their minds, but now after connecting, a screen similar to entering the game appears directly. What the hell?

But soon they found that there were different menus around this page. When they put the mouse on it, they finally found something familiar to them, for example, they could set the factories they needed here.

And the factory has the 3nm lithography machine production line they want.

These personnel probably also found some clues. After all, everyone is a high-tech talent, but they were not proficient at the beginning. Now after getting used to it, it is actually simple. There is an option for them to input in the settings. After the lithography machine production line.

There was an astonishing change on the screen in front of them in an instant. A lithography machine production plant rose directly from the ground, and then various production lines appeared in this plant.

As the most advanced domestic research institute for researching chips and lithography machines, they have actually seen these two things. In fact, chip design and lithography machine design are not the same job, but from another perspective, they It's also a job.

At least in their research institute, there are two groups researching this, and now both of their groups are conducting related tests in this area.

When a 3-nanometer lithography machine production line appeared, although the chip design team was a little surprised by the changes in the pictures 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 for What they see doesn't work, that's all.

What they are concerned about is that after the establishment of the lithography machine production line, a drawing input page similar to the real production line appeared on their page.

Here they can input all their designed chip parameters, drawings, etc., and then this 3nm lithography machine production line can produce the products they need.

And whether this product is successful and its performance, these can be further tested.

In fact, there is currently no 3nm lithography machine production line in the world, but there are some commonalities between 3nm and 7nm, and here we choose a 3nm production line, and the entire production line can be used for production.

Their research institute has actually produced a 7-nanometer lithography machine, and they even have plans for a 3-nanometer lithography machine.

The reason why there is no way to use it is because regardless of whether it is 7nm or 3nm, their yield rate is simply horrible, and it cannot be used in reality because the cost is too high, and the price of the manufactured chip is simply unaffordable. How can the machine have any competitiveness?

But in the illusion simulation program or the Pangu program, there is no problem. Anyway, these are all data simulations, so what if the yield rate is only 1%? Anyway, they are to test the performance of the chip.

However, the progress of another group of lithography machine design teams was much faster. In reality, they designed a 7nm lithography machine, but the yield rate was too impressive, so the lithography machine just had a look. A gimmick with no practical value.

After all, the 7-nanometer lithography machine of a foreign company has long been purchased and produced by a foundry. Huawei’s mobile phone chips have been produced for several generations using 7-nanometer manufacturing technology. Their lithography machine is purely for money. It exists to enhance the country's technical reserves in this area.

Because there is no other source of income, the improvement of lithography machines must be slow, and it cannot produce enough chips. The speed of finding problems is naturally slow, because they want to save money.

But in this program, they can produce without limit, and how much they produce is just a simulated data.

It's just that in the production process, the input data of the 7nm lithography machine designed by them is based on the actual production data response, including the programs used by these lithography machines.

Therefore, in the process of unlimited production, problems that can erupt naturally continue to appear.

The entire lithography machine design team immediately began to adjust their own lithography machines according to these problems. Many devices were used enough to find the problem.

Because Jiang Yanhai is near this scientific research institute, Er Dan's data transfer speed is very slow, and the results given by the illusion simulation program are also very fast.

In just over two days, the yield rate of the 7nm lithography machine designed by the lithography machine design team of the research institute has greatly increased from less than 40% in the initial program simulation to 90%!

The yield rate of 90% is still a bit low in reality. For example, the yield rate of some foundry companies is at least about 95%, and it can even reach 98% after skilled personnel and equipment adjustment.

But the yield rate of 90%, especially the chip manufacturing in China, which has always been in the international backward technology, is already of great production value!

The reason why the speed is so terrifying is because here, if they find any problems, as long as they propose a solution, the adjustment of the lithography machine production line can be completed in minutes by inputting a few data.

But in reality, you have to at least re-produce the relevant parts, and this delay is more than a little bit, but here you only need to change the data, and the simulated parts can be formed in an instant.

With a yield rate of 90%, the lithography machine design team is no longer ready to proceed with the design. The main reason is that they have not used this program before and do not know whether the program is reliable, but all the data returned by this program, in their opinion It's all very precise.

And there is only one reason for them to stop, they want to produce one in reality according to this latest improvement, and then actually test it in reality!

Compared with the progress of the lithography machine design team, the progress of the chip design team is naturally slower. After all, chip design is something that starts from scratch, and the lithography machine is more like an update.
