The conversation of everyone was very pleasant, Song Manli also drank some wine, her delicate face was dyed red, and her eyes became hazy.

Yang Jie also had seven or eight points of alcohol, and his head was also groggy, while Huo Xiaotian and Gu Xiaosong were also drunk.

Yang Jie endured his drunkenness and sent Huo Xiaotian and Gu Xiaosong away, and got into the car with Song Manli this time.

"Sister, are you okay?" Yang Jie asked as he looked at Song Manli beside him with concern.

"It's okay, I want to get some sleep, borrow your shoulder. Song Manli looked at Yang Jie with drunken eyes, and her soft words were coquettish.

"You sleep. A certain Yang Jie touched a place in his heart, he suppressed this inexplicable emotion, and said with a smile.

Song Manli had a smile on her face, leaned on Yang Jie's broad shoulders and closed her eyes.

The nose wafted from Song Manli's body mixed with the rich aroma of alcohol, and Yang Jie's heart was also full of tenderness.

Huo Xiaotian flew to Ukraine after a few days in Yanjing, and his current task is to expand his business there and search for talent.

Yang Jie and Song Manli also returned to Tanzhou City together in mid-October.

After rushing back to Tanzhou City, Yang Jie learned that Huayue Electronics Company had made a breakthrough in the 0,18 micron process technology, and he was also very happy and hurriedly rushed over.

When he arrived at Huayue Electronics Company, he found that XCMG, He Yuguang, Xi Haiqing and a group of technical engineers were all sad.

"What's going on?"

"Yang Shao, the yield rate of tape-out is too low, everyone is looking for problems, but they don't have a ......clue," He Yuguang said.

A large number of leaders and engineers from Huayue Electronics Co., Ltd., Zhongjing Microelectronics Co., Ltd., and Ruixing Technology Co., Ltd. are now gathered together to solve the problem of yield.

Huayue Electronics Co., Ltd. carried out the first round of engineering tape-out of the flash memory particles of Xinlan Technology Co., Ltd., and has taken out a very small number of engineering samples, but the 0.18 micron process is not mature, and the yield rate is low to death, and only 11 qualified products are obtained after testing after making five wafers in a row.

"Bring me the sample. Yang Jie said, Xu Shaoqiu and the others had a bright light in their eyes, and hurriedly asked the technicians to take the sample.

Huayue Electronics Company has an internal boiler, and the conference room is as warm as spring, Yang Jie looks at the computer and casts a photo of the sample under the electron microscope on the screen with a slide projector, and the microstructure on the chip in nanometers is magnified like a bucket, after looking at many photos, he already has a number in his heart.

"You have seen these photos before the meeting, and you have a good idea of the morphology and structure of the gate embedded layer, so I will analyze them for you to see if they are the same as the analysis you made yourself. ”

Looking at dozens of pairs of eyes looking at himself, Yang Jie also expressed his opinion: "The reason why there will be a large number of defective products that cannot be read and written in our engineering tape-out, and the yield rate is extremely low, although the main reason is that the current 0.18 micron experimental process is immature, but no matter how immature, the yield rate cannot be so low." I just looked at the photos, and the reason why we really got the defective product was because the gate diffusion layer of our buried wafer was abnormal. ”

In the conference room, XCMG was also relieved, this time he was the person in charge of tackling the 0.18 micron process technology, and he was also worried that he had a major problem in the technical route.

"You look at this electron microscope flaw detection diagram, the left is the good product this time, the right is the unqualified product, the difference between the normal form of the embedded layer diffusion structure on the left and the right is obvious, I know you must be thinking now, why do these defective products on the right appear? What is the problem?"

Many technicians in the conference room also spoke enthusiastically.

"Huang Haibo's judgment just now is right, and this situation is indeed related to our diffusion layer ion implantation process. ”

The named technician had a look of surprise in his eyes.

"Then let me ask you, what is wrong with this process?" Yang Jie asked.

The technician couldn't answer.

"Yang Shao, is it a problem with the vacuum degree of the injection machine?" asked Xu Shaoqiu.

"Yes, it is that the vacuum degree of the injector is not enough, which causes the thickness of the oxide film embedded in the diffusion layer to be thin in the middle and thick at the periphery, and the isolation of the thin part is poor, resulting in leakage in the middle. ”

Some of the engineers in the audience suddenly realized their expressions, and some nodded excitedly, indicating that as expected, Yang Jie's judgment was the same as theirs.

Yang Jie continued: "I think failure is also a good thing, it has given us the experience we have learned, if nothing happens, I don't think it's good, then everyone won't be able to learn anything." ”

He looked at Xi Haiqing and said, "Mr. Xi, you immediately take the improved vacuum parts of the new ion implanter currently under development of Ruixing Technology Company to upgrade and modify the equipment of Huayue Electronics Company." Judging from the vacuum parameters of the new equipment they gave, the problem should be solved immediately after the modification and upgrading, and after the second batch of engineering tape-outs in a few days, everyone can see the difference in the electron microscope pictures. ”

"Yes, Yang Shao, I'll arrange it immediately. ”

Some of the engineers here are still hanging in their hearts, worried about what if this modification and upgrade still can't solve the problem?

Yang Jie continued to press the mouse, changed the picture on the projector, and continued to explain: "This picture is very classic, this is a typical feature of poor adhesion of silicon cargo, and it is a problem of polysilicon growth process, as long as the cleaning process of silicon carcity is improved before growth, so as to eliminate the phenomenon of poor adhesion." ”

When several engineers in charge of silicon wafers heard this, they also hurriedly wrote down the improvement plan that Yang Jie said.

Yang Jie continued to explain to everyone the future process needs to improve the place and specific methods, everyone listened with relish, quickly took notes, everyone felt that Yang Jie opened a new door in front of them, and this door has been suffering from the blockade of Western technology and has never been able to peek into the end!

With the improvement of the manufacturing process, there are many problems involved, and even companies like Intel need to spend billions of dollars and engineers from all walks of life to tackle the problems together for each generation of process technology, which shows its difficulties!

But fortunately, Yang Jie himself has enough experience in this area, and the scientists and engineers present felt as if they were listening to a top expert from a world-class laboratory teaching top-secret technology, but the absurdity is that this expert is only twenty years old!

"Look, this is a photo of the polycrystalline silicon film after etching, what do you think of these scars for these etched spots?"

Seeing that everyone didn't speak, Yang Jie personally explained: "From the morphological analysis, this is caused by the insufficient dry etching allowance, mainly because the cooperation between the new lens of the lithography machine and the workpiece table has not yet reached perfection. ”

Yang Jie looked at He Yuguang and said, "Mr. He, although this problem has little impact, it still needs to be debugged again to minimize this situation." ”

"Okay, Yang Shao. He Yuguang nodded.

Everyone in the conference room listened carefully to Yang Jie talking about the problems in the process one by one, for fear of missing something.

Yang Jie also knew that Xu Shaoqiu of Huayue Electronics Company and the engineers of Zhongjing Microelectronics Company only mastered the 0.35 micron process technology in the FinFET process technology, and at least they had enough experience after mastering the first generation of process technology, so he naturally wanted to provide them with more experience in this.

The meeting was held in the evening, and Yang Jie was also dry-mouthed, and finally explained many problems to everyone.

Yang Jie stayed at home in Yuetai City for a few days, and when he went to Tanzhou City, Huayue Electronics Company made a comprehensive adjustment according to his plan, and the yield rate soared to 74%, which is very high, and it can be said that Huayue Electronics Company has completely mastered the process technology of 0.18 microns.

This is of great significance, and now the American Intel company has only maturely mastered the 0.13 micron process technology, and the 90 nanometer process technology is being tackled.

Strictly speaking, the process technology of the United States is only one generation ahead of Huaxia.

Yang Jie also called his father and asked him not to report the news to the above for the time being, and at the same time forbade the personnel of his company to disclose the news to the outside world.

If you shout to the outside world that Huaxia has conquered the 0.18 micron process technology, the United States will definitely send intelligence personnel to understand the situation, and when the time comes, it will find out that Ruixing Technology Company can produce lithography machines, and then we will definitely try our best to block the way for Ruixing Technology Company to import from the outside, and then everyone can only stare dryly.
