Hearing Yang Jie's words, He Yuguang, Xi Haiqing and others were also very excited.

In the past few years, the head office has been spending money on R&D, and the R&D staff has also been growing, with annual R&D funds of more than 2 billion, and it is still growing.

Because many of the technical solutions proposed by Yang Jie are very difficult, and the lithography machine is a very high-precision instrument, it takes a lot of effort to improve a certain index, and the goals set by the boss are world-class difficulties, He Yuguang has to work hard to find the top talents from all over the country and even from overseas to tackle the problem together.

In recent years, Huaxing Science and Technology Group Company has smashed six or seven billion yuan on this, but the total revenue created by the company is less than four billion, and the foundation is still supported by the head office.

He Yuguang heard that Yang Jie had to hold on to the domestic industrial chain before Ruixing Technology Company could go independently, and he and Xi Haiqing also sighed in their hearts-

The person who can have such a sober understanding of the domestic semiconductor industry and have an extremely firm will is Yang Shao!

"The etching machine technology of Ruixing Technology Company is now mature, but it can be fluttered in the international market first, a wafer factory needs forty or fifty units, and the international demand is still very large. ”

Yang Jie smiled and said: "Now the etching machine sold on the market costs two million US dollars, and we sell 10 million is already very cheap. ”

In recent years, Ruixing Technology Company has sold more than 200 units in China, and the domestic market has been robbed on the basis, and the production of etching machines has been domestic, and it will not be stuck in the neck.

Yang Jie is very confident that he will grab a part of the cake from the global etching machine equipment market of more than 10 billion US dollars.

He Yuguang and Xi Haiqing both nodded.

Tan Yunsong asked: "Yang Shao, have you read the flash memory particle design drawings and preparation process made by the New Blue Science and Technology Research Center?"

Yang Jie said: "There are some problems that need to be corrected, according to the current design, the production is very difficult, and the yield rate is very low. ”

Tan Yunsong hurriedly asked: "It's about to be experimentally trial-produced, won't it fail in this way?"

Yang Jie said with a smile: "Tonight, I will rush to Tanzhou to the R&D center to help correct it." ”

"Yang Shao personally went out on the horse, this time it's going to be finalized, right?" Tan Yunsong said with a smile.

"I'm just going to say what I think, and I'm going to ask them to fix it. ”

Yang Jie said with a smile: "They take the design of the IO input and output interface too seriously, without considering the difficulty of preparation and the process, the DMA engine design is not streamlined enough, which affects the access speed, the efficiency of the verification algorithm is not high, resulting in insufficient bad area inspection ability, and the data will often make errors after the particle application time is long." ”

Tan Yunsong almost cried: "Yang Shao, why didn't you say it earlier? I still think that the design is perfect? Han Xiaolong was still bragging everywhere two days ago, saying that at most seven or eight films can be successfully experimented." ”

"Their R&D idea is not wrong, as long as the design is slightly corrected, the preparation process can be shortened by 30%, the production cost will be greatly reduced, and the yield rate will be easy to increase in the future. ”

"Yang Shao, you are really a genius, you can see the problem at a glance, and you have even thought about how to correct it, with a genius like you, I think those big flash memory factories abroad are going to shed tears. ”

Yang Jie laughed, God didn't let himself be reborn easily, he had a large number of skill patents in hand, and it would be too tyrannical not to take out and use it!

"I wonder if Yang Shao, did you engage in IC in your last life?

"Mr. Tan, you are still a scientist! How can you still trust this!"

Tan Yunsong laughed: "There is no measure, there is such a rapid improvement in the semiconductor industry in China, this is a miracle! There is no measure to explain it with science." ”

"Isn't this the result that Mr. Tan is most looking forward to seeing? Yang Jie said with a smile.

In Vietnam, Yang Jie also emerged in the R&D center of Xinlan Technology Company, and the conference room was full of technical engineers from the company's R&D part, and there were more than 20 American engineers in the middle.

He pointed to the self-made PPT on the projection screen and said: "Look, under this polysilicon gate are three layers of edge films, which are tunneling oxide layers, silicon nitride, and barrier oxide layers, among which silicon nitride has a very high density of electron traps, which can capture electrons and achieve the goal of storing charge, charged is 1, and uncharged is 0." ”

Yang Jie continued: "Silicon nitride was only used to cover the underlying metal, and because there were few pinholes, the diffusion of water vapor and sodium in the silicon nitride material was very slow, and this time we injected silicon nitride into the edge of the channel. ”

He saw that everyone showed a confused expression, and explained with a smile: "We all know that there are two kinds of carriers in semiconductors, one is electrons, and the other is holes.

"Due to the circumference nature of silicon nitride, the electrons generated by the thermal electron effect can only be injected and confined to the edge of the channel. It is in this way that once the two sides of the channel are fully charged, it is 11, and all the uncharged is 00, but once we erase one side of the channel on both sides separately, there will be four situations, one is 01, and the other is 10, so we have doubled the existing flash memory capacity without complex process transformation. ”

"On this basis, we can develop multi-voltage gate multi-layer charge injection technology products in the future to achieve multi-layer stacking, which can be used to maximize the capacity of flash memory on the existing process technology, rather than completely relying on the improvement of the process technology, which also greatly reduces the cost of flash memory. ”

Hearing this, there was an uproar in the conference room, everyone was extremely surprised, Han Xiaolong applauded excitedly at this time, and then everyone applauded vigorously.

"Yang Shao, you are too godly! We have to hurry up and experiment! Hurry up and write a paper and apply for a patent!" Han Xiaolong said excitedly.

"Mr. Yang, your assumption is too perfect! I feel that it is feasible! It is really feasible! Why has no one thought of this way before! You are such a genius!"

At this time, several American engineers stood up excitedly and shouted.

"Yang Shao, I have a question, this kind of technical route does allow a storage unit to carry four pieces of information, which is double the previous amount, but how to read it next?" asked an engineer with a raised hand.

"The voltage in these four cases is different, we just need to design a set of decoding circuits for reading and parsing the data, and the specific decoding circuits still need to be set by you. Yang Jie said with a smile.

"Yang Shao, we will design the decoding circuit immediately, I almost have an idea, I promise to take out the chip design next week, and then we can design the process flow, and at the end of the month at the latest, we can carry out the first engineering tape-out!"

Han Xiaolong said excitedly.

"Very well, I am waiting for good news from you. Yang Jie saw that everyone was like being beaten with chicken blood, and nodded with a smile.

Now that he has pierced this layer of window paper, Xinlan Technology will become the first design company in the world to adopt 3D flash memory technology! It can also be said to completely get rid of the current shackles of Intel and Toshiba's flash memory patents, and offset the patent fees to be paid to the International Flash Technology Alliance!

As long as the chip is successfully taped out and the patent application is obtained, these major foreign flash memory manufacturers will in turn have to pay patent fees to the company!

Seeing Yang Jie standing there with a smiling face, Han Xiaolong and the others were extremely sighed in their hearts: Yang Shao is really a god!

Yang Jie was also planning to stay here to personally participate in the next chip design and development, but a phone call the next day made him have to rush to the electrochemistry laboratory-

Premier Zhu came to inspect the electrochemical laboratory!
