Rebirth: I carry a desktop computer inside me

After receiving phone calls from Yi Guobin and Bai Chunhua, Jiang informed Guo Xiaoming and asked him to temporarily cancel the holiday arrangement for the production line workers.

Of course, Jiang Cheng will not say the specific reason, but only that there is a temporary emergency mission.

For engineers who cannot take leave, in addition to the statutory triple salary, appropriate incentives will be issued for this temporary action.

Of course, Chinese New Year's Eve and the third day of the first lunar month, there will still be a holiday for everyone, but it can't be so long.

Fenghuo Semiconductor's 12-inch wafer production line, under the dim light, Jiang Cheng took engineers to prepare for the first official tape-out.

Prior to this, after more than a month of commissioning, the engineers had basically become familiar with the entire production process.

However, this time it is a real tape-out, and it is still Maple Fire Group's own film.

In the design of this piece, the resistance storage R&D department has completed the design, and Jiang Cheng recognized this in the in vivo simulation.

And the pattern is placed on the light mask.

Well, next, there's manufacturing.

Maple Semiconductor's wafers are mainly from foreign LG and blue globular companies, and hundreds of thousands of pieces have been purchased.

This is not that Jiang Cheng does not want domestic, but that no company can meet this standard at present.

Throughout the process, Jiang Cheng is guiding. While instructing, the simulation is carried out in case which step produces what moth.

The engineers, including Guo Xiaoming, were a little surprised to find that this time Jiang Cheng was particularly demanding, even if it was a slight mistake, Jiang Cheng would criticize it sharply.

Although it is not swearing, it obviously makes everyone feel more stressed.

The chairman of the group personally guides and supervises, can you not be nervous?

Gluing, photolithography, developing, etching, to the addition of impurities, starting from the exposed area on the silicon wafer, into a mixture of chemical ions.

After this series of repetitive and precise work, a wafer is densely packed with chips.

When measuring electrical characteristics, Jiang Cheng simulated in vivo testing by the way, and the speed in the body was much faster, and through Jiang Cheng's own self-coding neural network, he quickly found the problem die.

"The yield should be around 75%." Without waiting for the test results, Jiang Cheng spoke.

It seems that there are still some problems.

The lithography machine and other equipment in Jiang Cheng's body are simulated in the body, which is an absolutely clean space, and the actual production line in this regard cannot be compared.

Moreover, Jiang Cheng estimates that there is still room for improvement in some links.

After a while, the results were similar to what Jiang Cheng said, and the results of the test here were slightly higher, 79%.

The engineer moves on to the next step, cutting Die, soldering the pins and mold sealing.

A small resistance memory chip is built.

Test engineers conduct detailed tests.

In the process of waiting, Jiang Cheng and the yield engineers began to study the relevant process improvement step by step.

The whole process, without multiple exposure, should not be a big problem.

Just keep improving.

Out of the laboratory, Guo Xiaoming let out a long breath, "Jiang Dong, your requirements are really high. In

his eyes, they are just starting out, with a yield of nearly 80%, which is very good.

"At least a yield of more than 90%." Jiang Cheng shook his head, "I followed every step, but there may still be some things that I didn't notice either."

Guo Xiaoming raised his thumb, "Jiang Dong, your understanding of chip manufacturing is really too profound, I see that those engineers adore you super much."

Jiang Cheng shook his head and said in his heart, who let me have a production line in my body?

Others may still be touching it for the first time, but Jiang Cheng has actually simulated that he is about to vomit.

"Have a good rest today, tomorrow President Bai Chunhua and Minister Yi Guobin of the Chinese Academy of Sciences will come to see our production line and let everyone feel refreshed." Jiang Cheng took off his dust-free suit and walked towards Guo Xiaoming.

Guo Xiaoming was stunned, "Look at the production line? Could it be, which big leader is coming?

"It's not clear what exactly, get ready."

Jiang Cheng glanced at him, but he didn't expect that this technical man's mind was still a little alive.

You can react at once.

Guo Xiaoming nodded, "Jiang Dong, with you here, we must be fine."

"Okay, don't say that." Jiang Cheng waved his hand, not cold to these words.

Guanglin County.

Since the Maple Fire Group invested in the construction of Jiangluo Hot Spring Town in Guanglin County, the county attached great importance to it, and it took only one month to requisition the land.

Manager Chen Zikai of Fenghuo led the winning card construction company according to the design plan, quickly promoted the construction, and as soon as January changed, the tourist service center of the hot spring town and the garden in front were basically built, and the 23-story crescent-shaped hot spring hotel on the side also had seven or eight floors.

The hot spring area is still under construction and is expected to open for soft opening in the second half of 16 years.

It will soon be the Lunar New Year, and Chen Zikai is ready to go back to his hometown for the New Year.

Workers also stopped working, and there was no point in staying.

Originally, he thought of waiting for Jiang Cheng to come back and report the progress of the construction of the hot spring town with him, but later learned that Jiang Cheng was estimated to not return so soon because of something.

No way, the New Year home still has to go back.

So, at this time, Chen Zikai, who had a big belly, took two boxes of essence ham sent by his hometown and drove them to Jiang Cheng's home.

Because he has been working in Guanglin County for a long time, he and Jiang Yiping are very familiar.

"President Jiang."

After Jiang Yiping opened the door, he saw Chen Zikai and was a little surprised, "Manager Chen, don't you go back for the New Year?"

"Just about to go back, take advantage of the New Year, bring some hometown souvenirs, President Jiang, you can taste it." Chen Zikai came in with some effort.

Chen Ru was serving soup to Yu Xinran, and then poked his head over, "Eh, Manager Chen, please come in, why do you still bring something!"

"It's just a souvenir, it's not worth anything." Chen Zikai put down his things, added shoe covers, came in, and greeted Yu Xinran again, "President Yu."

Yu Xinran glanced at him, knowing what the other party's mind was, and did not break it, and said with a slight smile, "Manager Chen."

Chen Zikai smiled and sat down a little restrained, "Hasn't Jiang Dong come back yet?"

"No, there is still something on his side, is Manager Chen looking for something?"

This time involves the affairs on the company's side, Jiang Yiping and Chen Ru can't interject, mainly Yu Xinran.

Chen Zikai explained, "Jiangluo Hot Spring Town originally wanted to report the situation with Jiang Dong.

"Well, what's the situation with construction now?" Yu Xinran asked.

"Now the construction progress is very fast, it is expected that in June this year, the main body of the hotel, the hot spring pool can be built, and the second half of the year is decoration, greening and road construction..."

Yu Xinran nodded slightly as he listened, "It's hard for you." I will talk to Jiang Cheng about these developments.

"That's bothering you." Chen Zikai got up, it was close to the New Year, it was not good to keep the rice, and then resigned and left.

However, although Chen Ru kept letting him take it back, Chen Zikai insisted on not allowing it, so he had to give up.

Chen Ru opened it and looked at it, but it was two thick hams, "This package says essence ham, is it expensive?"

Yu Xinran thought for a while and said, "It seems that it will cost eight or nine hundred."

"Eh, it's so expensive, what do you do with this thing?" Chen Ru was a little speechless.

"I'll talk to Chengzi when I go back."
