"First of all, it needs to be clear that Flint Technology's 3D flash memory technology involves two levels of 3D, storage cells, and storage particle packaging. 3≠ 8 3≠ 8 3≠ read 3 ≠ books, .↗.o ●"

In one sentence, it caused an uproar.

"Three-dimensional storage unit and 3D packaging realize the ...... at the same time"

The one who does the packaging is even more energetic. Although this package is not the other, who knows if there is a chance in it?

Lin Yaodong clicked on the next slide, and Gu Song said: "In the laboratory, we have completed the three-dimensional storage unit architecture of four architectures. According to the needs of applying for patents, the general idea of these four structures will be published. Now, of course, for the first time. ”

None of the tech-savvy and corporate people in the audience listened to him, and only focused on the four structural diagrams presented on the slides.

Gu Song waited for them to digest for more than ten seconds before approaching the microphone and raising the volume: "Please pay attention, although the core details of the process will not be fully disclosed, but with the foreign research foundation and their energy, they must have obtained the patent application materials submitted by me at this moment and are tackling key problems in the laboratory." ”

Only then did the people in the audience shift their attention to Gu Song, and Gu Song said: "There is not enough time. The good news now is that with four architectures and four sets of technologies, I am sure that I will block foreign countries for at least 3-5 years at the patent level. During this time, the chances that they will be able to find a fifth set of structures are very small. This means that in 3 to 5 years, we have to gain a foothold in the field of flash memory and catch up with the world's best in terms of process technology. ”

The field of flash memory is firmly established, and now that this technology is in hand, the problem is not too big. But the process technology has caught up with the world's first-class level...... Including Bao Ruozhang and Rujing, the audience fell silent.

"As for the TSV packaging process, I only completed the application for the full set of processes on the flash memory chip. ∈ 8 ∈ 8 ∈ read the ∈ book, .2∞3.↓o But this packaging process, of course, is not only used in flash memory. Once foreign giants complete breakthroughs in other fields, it will widen the gap in those fields. ”

Zhang Rujing looked at the schematic diagram of the TSV packaging process on the slide, and nodded heavily in his heart.

Gu Song said in a serious tone: "Everyone, let go of your prejudices and suppress some selfishness first. We can't fully predict the inspiration of scientific research ideas and the extension of application fields brought by a new technology to foreign countries. This is a fleeting opportunity, if we can't unite at this time, we can build a 3D flash memory factory first and gain a sufficient share of the global market first. Well, this cake does not exist. I have a patent in hand, and I don't want to expect foreign manufacturers to make the cake bigger and give me a small bite each. ”

"If we want to make this cake bigger, we must first ensure that the world's largest and most advanced 3D flash memory production base will be in China in the future! Now, the 2D flash memory process technology has matured at the 130nm level, and this year's MLC architecture 2D flash memory will be mass-produced and put on the market, and the 12-inch wafer production line will be adopted. But now, flintstone Technology's 3D flash memory can only be considered to try tape-out mass production on the 250nm or even 350nm process, and it is on an 8-inch wafer. ”

Gu Song paused and said sincerely: "There are many difficulties, and the advantages are not as big as imagined, because our foundation is too poor. Even the most direct difficulty, the first batch of 3D flash memory, now needs to be tackled if you want to be successful in tape-out. Can I choose to go to Intel, Toshiba, and Samsung to work together for joint research and development, tape-out and mass production?"

Looking at Gu Song's expression, the people in the audience finally came to their senses.

Yes, the technology of 3D flash memory is indeed epoch-making. But now what people want is cake that they can eat in their mouths. If it can't be mass-produced as soon as possible, what does this cake have to do with itself?

If you want mass production, the equipment is worse than others, the process is backward than others, and there is not even a special flash memory factory to jointly develop together.

Huaxin International's production line is the most advanced, but it was established at the beginning of the development direction of a pure foundry. Huahong's 8-inch production line can only achieve mature mass production of 500nm process. Belling Microelectronics is also very difficult.

Wouldn't it be child's play to consider sharing the cake now?

This is the first step that Xinhuo Technology is facing now. The 8-inch wafer production line can complete the mass production of a complete set of processes at the 250nm level as much as possible. The equipment required, the team, which is a real difficulty. ”

Gu Song nodded at Lin Yaodong, and entered the second link with the content of the slide: "I put forward my solution idea." At the same time as the construction of Xinhuo Technology, I want to choose a chip factory to cooperate, and I will be responsible for the mass production process of 8-inch wafers and 250nm process, and try to tape-out. The chip factory will obtain a permanent license for the architecture and first-generation process, and will mass-produce its own 3D flash memory under an independent brand in the future. ”

Zhang Rujing, Hua Hong, and the representatives of Belling Microelectronics all showed expectant looks. 8-inch production line, 250nm process, their production line can meet the basic conditions.

Gu Song didn't wait for them to digest it, and continued: "As for Xinhuo Technology, I want to directly go to the 12-inch wafer and 130nm process. I will come up with the second set of architecture and exchange it with a large foreign manufacturer. Similarly, what I exchanged abroad was also based on the original process of 8-inch wafers and 250nm process, and I was not responsible for tackling key problems in the mass production process. This plan is not absolute, if any chip factory here has the ability to directly introduce this production line to me, then I don't have to give foreign authorization. This production line is equivalent to the permanent transfer of a set of architecture and original process patents. ”

"If possible, I don't want to be the first to realize the mass production of 3D flash memory abroad. But again, I don't want to start with 8-inch wafers and 250nm to compete with other MLC chips that are mass-produced in 130nm or even 90nm on 12-inch wafer lines. ”

Zhang Rujing smiled wryly, a set of 12-inch production lines and equipment that can realize 130nm process technology are used to permanently exchange a set of 3D flash memory patents, of course, it is worth it, but I am afraid that foreign factories will be difficult to refuse. It's just that Gu Song's conditions for them are definitely not as generous as those for domestic enterprises, and they must have some other requirements.

But he tried his best to only introduce an 8-inch wafer production line. 12-inch wafer production line...... This is a wafer production line that has just matured and been put into mass production in 01.

Han Jingwei whispered to Wang Bang about the difficulties in the introduction of 12-inch wafer production, and Wang Bang also looked serious.

"After talking about the difficulties of equipment, let's talk about the difficulties of people. The person in charge of Xinhuo Technology, I have already confirmed. Liao Qingshan, the production supervisor of the Bay Semiconductor Manufacturing Co., Ltd., has confirmed to join Xinhuo Technology. ”

Zhang Rujing raised his head abruptly and stared at Gu Song.

The action is so fast, Liao Qingshan...... This is an old acquaintance, the backbone of Wanji, who is regarded as a figure cultivated by the next generation of leadership. Got dug up so quickly?

"There are generals and no soldiers, there is no point. Gu Song glanced at Zhang Rujing twice, "When tape-out, the two sets of people participate and learn together, this is my cooperation requirement." ”

"As for future plans, let's put them aside for now. Cooperate with tape-out and help Xinhuo Technology introduce 12-inch wafer production line and 130nm process equipment, what are your ways and ideas, let's communicate first. ”

In the audience, the leaders of Huhai City and Zhang Rujing took the lead in standing up...... 11. Baidu: Read the latest chapter of "The Life of Rebirth, When Fighting for Literature" for free for the first time.
