When everyone heard this, they also frowned.

They all seem to think that this matter is a bit of a big deal.

Wei Haoguang said: "If it doesn't work, let's find an outside OEM?" OEM is not our production. There shouldn't be any technical issues involved. ”

Su Han said: "OEM can't either. Isn't it necessary to run the data package drawings to others? At that time, the chip drawings we worked so hard to design were taken away. In any case, it must also be produced domestically. If not. It's a big deal that I will open a chip production company by myself, all of which use domestic equipment, and we will be self-sufficient. ”

Hu Guangnan said: "But the problem is that now our domestic lithography machine is not only backward in light source, but also backward in exposure process, even if we are willing to use it, the accuracy is about 1.2 microns at most, and the multiple exposure technology you said requires projection exposure!" Even if we can overcome it, it is about one micron at most, and even 386 is not included in the process, but the yield rate will further decline.

If you really plan to use a domestic lithography machine to realize the dual-core core display function of the processor we designed, I will say something ugly, the yield rate may not even be five percent at that time. ”

Everyone nodded when they heard this...... After all, the quality of domestic lithography machines is like this, and it is not possible to improve it in the short term.

Su Han said: "No matter what. It is also necessary to use domestic lithography machines, and this major premise cannot be changed. As for what you said, I've thought about it. In fact, increasing the size of the chip may not necessarily improve the yield rate, as long as the method is appropriate. ”

Everyone was a little wide-eyed when they heard this.

The larger the chip, the lower the yield rate, this is basic common sense, how can it be possible to improve the yield rate?

It's not physics anymore, it's a myth, okay.

Wei Haoguang said: "Su Han, do you have any good ideas?" ”

Su Han nodded and said, "Since we can't use lithography machines, we can start with packaging." I envisioned a new technology for chip package integration.

Here's how it works.

We designed the chip to be very small.

As long as the chip is small enough, the probability of local contamination, exposure failure or touching dead pixels will be reduced, and the yield rate will be improved. When the time comes, let's combine these small chips with different functions to form a more powerful large chip, and the number of transistors will not come up.

The key to this technology vision is the fragmented functional combination and packaging.

Packaging technology does not belong to the improvement of lithography accuracy, and it is easy to achieve technological breakthroughs in a short period of time.

When the time comes, let's use trivial small chips to make up a big chip, and the yield rate and processor performance will be preserved. ”

Everyone was stunned when they heard this!

The people here are almost all elites in the field of chips and computers.

In an instant, he understood what Su Han meant.

This method is too brainy!

Use fragmented small chips to form a powerful big chip.

In this way, the bottleneck of the lithography machine process can be bypassed.

Use fragmented integration of ideas and packaging technology to achieve real corner overtaking.

This not only improves the yield rate, but also increases the number of transistors and the combat effectiveness of the processor.

Awesome!

Jiang Binglu said with a shocked face: "Su Han, you are too powerful!" How did you come up with this trick? ”

Wei Haoguang also smiled: "You kid is really a genius." ”

Hu Guangnan also admired it at this time.

They racked their brains and couldn't help it.

Su Han easily set the general direction.

Su Han thought of something again, and said, "That's right, Dean Jiang." You should be familiar with the microelectronics schools of major schools, right? ”

"Cooked. What's wrong? ”

"I thought about it and decided that we had to speed up the development of lithography machines and related packaging equipment. In fact, there has been no major breakthrough in international light source technology for many years. Come to think of it, it's actually a good time for us to overtake in corners. Money is not a problem, the key is that there is not enough talent, can you find a way to contact the major colleges, let's form a lithography machine chip semiconductor development alliance to promote the equipment manufacturing level of the chip manufacturing industry.

It is better to bring down the experts of the Institute of Optoelectronics of the National Academy of Sciences, 701 Factory, 708 Factory, and 709 Factory. I'll take care of the money, the key is talent and technology. ”

"How much money are you going to invest?"

"R&D doesn't cost much money, and an investment of five billion is enough. Let's organize a team, as long as we can advance our G light source to the I light source within a year, it is a big breakthrough, the exposure process is a little behind, it doesn't matter, as long as it can achieve automatic projection exposure.

At that time, our chip process will definitely be able to enter 800 nanometers, and then we can advance the process accuracy to 400 nanometers with multiple exposures.

At that time, we will not be much worse than 586 in terms of technology. Then use my chip integration package idea, increase the number of transistors, chip performance will definitely be greatly improved, I believe that even the chip iteration of Intel is limited by the light source, it is impossible to improve much. When the time comes, we'll definitely be able to overtake those bastards on the straights in the retail market. ”

Everyone showed excited expressions when they heard this.

The thought of beating Intel in the chip market is like a dream.

Su Han said: "Dean Jiang, this is going to trouble your old face." How do you say that you are also an expert of the National Engineering Corps, the dean of the School of Microelectronics of Mushui University, the eldest of the elders, I believe that you must have face in organizing this matter. ”

Jiang Binglu said: "You kid is really tired and can't pay for his life." ”

Hahahaha!

The people around him also laughed.

If all the things Su Han said can be realized, then the domestic lithography machine is likely to have a big breakthrough in only one or two years.

Jiang Binglu gritted his teeth and said, "Okay, I've decided, give up my old face, and I must organize this matter." ”

Su Han said: "Then this matter will be handed over to Dean Jiang." That's right, Vice President Hu. According to my design ideas, you take advantage of this time to complete the chip design, as long as the technology meets the standard, the chip will definitely be able to achieve mass production in the future. You can rest assured of this! ”

"Okay, Mr. Su!"

……

Su Han returned to the software R&D center in Modu again.

The Longhan Hotel will officially open for business.

With the support of Su Han's large amount of money, the decoration of the Longhan Hotel is naturally extremely luxurious, and to be honest, it is not much worse than the real Burj Al Arab.

It almost reached five stars at the opening.

As one of the owners of Longhan Hotel, Su Han naturally wanted to participate in the opening event.

However, Su Han is not very fond of socializing.

After participating in the ribbon cutting, he pulled aside the deputy representative of the official family of a certain magic capital.

said that he wanted to invest in opening a chip manufacturing company in Modu.

I hope to approve a piece of land.
